SSRS 2008 R2 - Range Bar Chart (GANTT) - updated

Hi All,

Sorry for not posting any updates on my blog. 

Anyways I just updated the Range bar chart (GANTT) using SSRS 2008 R2 Business Intelligent Studio. And here is the actual output of the report:

Here are the video tutorials of implementing this report:

Part 1

Part 2

Click HERE to download the RDL file (File -> Download) for this Range Bar Chart Report.

Below given details are references for you guys:

How to implement this Report:
The below given image has all regions identified to implement this report:

In the above picture, all marked regions (1, 2, 3, and 4) are individual Range Bar Charts with updated properties and properly aligned for the look and feel. 

SELECT TaskId, TaskName, StartDate, EndDate, SubTaskId,
      CONVERT(datetime, '1/1/2012') AS TempStart, CONVERT(datetime, '12/12/2012') AS TempEnd
      SELECT TaskId, TaskName, StartDate, EndDate, 0 AS SubTaskId FROM Task
      SELECT TaskId, TaskName, StartDate, EndDate, SubTaskId FROM SubTask
) AS tasks
ORDER BY TaskId, SubTaskId

The query is returning the following fields:

  • TaskId
  • TaskName
  • StartDate
  • EndDate
  • SubTaskId
  • TempStart
  • TempEnd
For time being ignore the fields TempStart, and TempEnd. Let's start with chart. Right click on the Report design area and insert a Range Bar Chart to report.

After adding the chart to report the chart looks like this:
As you can observe, this part is little different than in SSRS 2008.  Values is where we select the date range fields, and Category Groups is where we add columns to group data. I added EndDate to Values. Select the EndDate and right click select "Series Properties" and update the series as given below.

As you can see I also added TaskId and SubTaskId to the Categories Groups. You can right click on each of the Category Group select "Category Group Properies" to change the sort options. As I added integer fields, I am changing my sort direction to Z - A form A-Z. Here is how the properties window looks like:

Repeat the same for SubTaskId Category Group As well. Once this is done, let us get rid of all the titles, legends, and Vertical Axis. For titles you can simply select and delete. For Vertical Axis, select the Axis and uncheck "Show Axis". Now the report should look like this:
And the report output should look like:
Now Go back to Design mode and select the Horizontal Axis, right click select "Horizontal Axis Properties".

  • Select Labels -> then check "Hide axis lables" checkbox.
  • Select Major Tick Marks -> then check "Hide major tcik marks" checkbox

Now when you view the report it should look like this:
As you can see except the margins, rest is looking good. You can update the label for the Series in the chart as explained in my previous post. Before discussing how to remove the margins, let me explain some customization you can do with the Major/Minor Grid Lines for Horizontal Axis. Select the Horizontal Axis, and go to the properties window. Here you see two important sections that controls Major and Minor Grid Lines. 

As you can see both Major Grid Lines and Minor Grid Lines has same fields. Here is how we can use it.

  • Enabled : This has values of Auto, False, True. False will make them not to be shown in the chart, and True does show the lines on the chart. I will explain later about Auto option, for time being you can change the value to True.
  • Interval Type:  This is very important fields which controls where to show the lines. It has the following values. 
  • Interval : This is an integer field. You set the interval between the lines.

If you set Interval Type as Months and Interval as 2, then for each two months in the chart you can see grid line. And the remaining fields under this group are to control the line style and color. I let you guys to play around it. You can set different colors for Major and Minor grids. You can hard-code the Interval and Interval Tyoe. Or a better options would be to have two Report Parameters MyInterval and MyIntervalType  and use these in the formula expression. I will leave it to you guys to play with these parameters.

Now we go back to removing the margins for the chart area. I am saving this for last because once the margins are removed it is difficult to select individual parts of chart in design areas. Go to design mode, and click on the chart. Now click again to select the chart area. On the properties window ensure Chart Area is selected. It has the following two properties.

  • CustomInnerPlotPosition
  • CustomPosition

By default both properties has Enabled property set to False. You make it to True to change the Height and Width of chart area. Both Height and Width are set to value from 0 - 100, which means it is a percentage. CustomInnerPlotPostion will let you control the Height and Width of the chart area. And CustomPosition will let you control the area of the chart within the selected chart area. Here are some exaples:

I set the CustomPosition and CustomInnerPlotPosition to 100.

Now we go to the Months bar chart. Here is how you can do that. Copy the current chart and paste it in the report. Now we modify the copy to look like the the Months bar.
Select the copies chart. Go to properties window, select Chart Areas collection. This is another way you can go to the CustomInnerPlotPosition and CustomPosition properties. I changed the CustomInnerPlotPostion as given below.

Now Select the Horizontal Axis, and go to properties window. Set LabelsFormat to '="MMM"' and MajorTickMarks -> Enabled to True.  You can check other parameters like LabelInterval, and LabelIntervalType to control at what interval to show the labels.
Now Chart Data -> Select EndDate, Go to Properties Window. Now update the CustomProperties -> PointWidth to 0.
Now click on the report, and click again to select the chart area. Go to Properties window -> CustomInnerPlotPosition. Set Height to 0.01
Then adjust the height of the report, and align with the original report like shown below. You can also view the output of the report given below.
Now we are almost done with the Months bar. You can copy and paste this Months chart and modify the Lables format to '="yyyy"' to get years and Change the Interval to 1, and IntervalType to "Years".

Now lets make another copy of the original chart and update some properties to show the task name. Select the copied chart and Chart Data -> Right click on EndDate select Series Properties and change the to TempEnd and TempStart instead of EndDate and StartDate.

Select the TempEnd/TempStart Series. Go to Properties Window, set Lable to =Fields!TaskName.Value

Now Select the Major Grid Lines on this report, right click -> Un-check the check box - Show GridLines

Adjust the width of the chart so that it looks like another column. Here is the how it looks like.

We are almost there .. Now lets start with finishing touches.
First let us give different color for main task and sub task in the Task Name chart. Select the Date Series added to Chart Data. Go to Properties Window -> 
Custom Attributes section:
          Bar Label Style - Set it to Outside
Appearance section:
          Label - set the value to =iif(Fields!SubTaskId.Value = 0, "Silver", "Beige") . This will give Silver color to Main Task and Beige Color to sub tasks (because for main task row, subtaskid will be 0).

And the report output is:

Now we do the same to Main chart.
Select the Chart Data -> EndDate and Go to Properties Window.

Custom Attributes section: 
     BarLabelStyle - set to Outside
     DrawingStyle - set to Cylinder

Appearance section:
     Color - set to expression  =iif(Fields!SubTaskId.Value = 0, "Aqua", "Khaki") . This will give Aqua color to Main task and Khaki color to sub tasks.

Label section:
     Label - set to expression  =DateDiff("D", Fields!StartDate.Value, Fields!EndDate.Value).ToString() + " days" . This will display the task duration in days as label.
      Visible - set this to True

Finally add a Textbox just above the Task Bar chart so that it looks like a Column Header. VerticalAlign the text to Middle, textalign to Center, and give a border and your GANTT chart is ready. Here is the final report output is:

You might be wondering what is the purpose of the database fields TempStart, TempEnd. Here is the reason: Range Bar Chart doesn't show the report if there is no date range. Main task may have a start and end date, but sub-tasks may be having these values as null. And our requirement is to show all the tasks in the chart irrespective of date range. So, I added the columns TempStart, TempEnd which always has default values and I can use this to show the Task Name chart. You can add multiple charts to show other data as well (like Task Name).

You can use formula expressions to controls appearance of the report in many ways. I just explained a couple. 

Please go through the video tutorial added.

Enjoy folks!!!


  1. Hi Swamy - this is really helpful as I try to make this work. Unfortunately the link is coming up as broken. Could you double check it?

  2. Updated the link.. Let me know if this works.


    1. Hi Swamy,

      You blog is superb! It's really helped me to design some of my range chart reports. I was wondering whether you can help me to create calendar view range chart. I have done a report as a matrix view in SSRS how ever I would like to create a visual calendar view. The data set as below...

  3. Good Morning,
    You have another blog post that has a chart towards the bottom. 3rd from the bottom actually. I was wondering if you had documentation on that chart. How did you do it? I've posted the link below.

    Is there any way I could get you to Email me at I have no idea of knowing when/if you'll update this. Thanks!

  4. If possible we could also talk by phone. I see by your profile that you're here in Houston. I look forward to a response either way.

    Thanks for your time.

  5. This comment has been removed by the author.

  6. Hi Gavindra,

    You need to add this rdl file as Add Existing Item to the SSRS project. Then you will be able to see the chart instead of xml version.


  7. This comment has been removed by the author.

  8. This comment has been removed by the author.

  9. Select Horizontal Axis -> Go to Properties Window and update the LabelsFormat to ="MMM"

  10. Swamy, you have a Gantt Chart on another page that has a status bar going through the center. Can you tell me how get that status bar in there along with the task bar?


  11. This comment has been removed by the author.

  12. This comment has been removed by the author.

  13. Please go to the beginning of this Blog. You will see 2 videos for the tutorial.


  14. can you please help me how to add month name and corresponding dates in the month to show in the header instead of show only month name exactly like in this image

  15. Hi Viniston,

    You need to give Interval=1, IntervalType=Days, and LabelFormat as "dd" or "DD" for the chart (Horizontal Axis Properties) to show dates. You can play with the LabelFormat to control what to show as label. Please check date formats.


    1. Thanks Swamy .... you are doing nice.....please kepp it up.....

  16. Hi Swamy,

    Thank you for this very interesting post ! Very usefull and very easy to understand thanks to your detailled explanations.
    Could you try to show a task with start and end at the exactly same timestamp ?
    It won't display, do you have an idea to fix this ?

    Kind regards,

    1. Hi Vincent,
      I think if start and end time have same timestamp, there is nothing to show as bar. But you can always show task name as label with some status saying start and end time are same or finished. Or if you have to show a bar, you can always add a buffer days/months to end date if start and end date is same. Hope this helps.


    2. Hi Swamy,

      Thanks a bunch. I fixed this directly in the DataSet :
      WHEN ScheduledStart=ScheduledEnd THEN DATEADD(hh,2,ScheduledEnd)
      ELSE ScheduledEnd
      END AS ScheduledEnd


  17. Hi Swamy,
    First of all thank for your useful information. I am stuck somewhere, When I try to create a drill down gantt chart in ssrs 2008 r2. First, it shows the information of the projects. When i click the project then it shows the information of the tasks and sub tasks. Could it be possible on SSRS? Could you please give me some information how do i accomplish this report?

    1. Hi Shiva,

      I think it may be possible, I am not sure. Let me try it myself. Please do not expect any responses soon as it takes time.


    2. Hi,

      I did this, very easy ! On the Chart Series (the bar) right click for the series properties. There you have Action, select "Go to report" select the correct report and add the requested parameters.


  18. Swamy,

    do you have any idea how to set the height of the bar as fixed ?

    Kind regards,

    1. Hi Vincent,

      You cannot really set a fixed height for the bar. It actually calculates automatically based on rows for the page. One thing you could do is use DynamicHeight. Set the DynamicHeight to a formula that gives the height based on number of rows retrieved from database. Now as the height is fixed, you will always see fixed height for the bar. This should work.


    2. Hi Narayana, it should be better to increment automatically the height of the chart to maintain almost fixed the height of a single bar of the range bar chart. Is it to possible to do it?

  19. Swamy,
    Great documentation and tutorial. Wondering if its possible to have a range bar chart show activity during a time range which has breaks in it. For example, I am attemmpting to plot the weeks a project was worked on, however its possible the work wasn't done continuously. A project may have been worked on weeks 15, 16, 17 and 19...with no work being done on the project during week 18. I would like to show the activity on the project as a single bar going from week 15 to week 19, with a blank or break in the bar at week 18. Hope this makes sense. Thanks in advance for your time and response. Jim

  20. Swami,
    What I would hope to achieve is having the subtasks on the same row as consecutive phases of the main task. I would even show only the subtasks on the same row, and display the tasks only as "legends" in the left chart. How could this be possible in SRSS? (It should look like I tried to show below)

    |Task 1| | Subtask1-1 | Subtask1-2 |
    |Task 2| | Subtask2-1 | Subtask2-2 |Subtask2-3|

  21. Well, the spaces were not displayed correctly, but you can assume each task is starting/ending in different moments, not all together at the same time. The chart would be like a Grantt, but instead of bars I would like to have "stacked" bars:)

  22. Hi Swamy,
    Do you have any idea how to make an arrow that go from the end of the bar to the beginning of the next one when there is a dependency between tasks?

  23. hi swamy...
    any idea if the two sub tasks started to show them horizontally...

  24. Thanks for this blog. Saved me countless hours during my report design


  25. Hi, Swamy, i want put a line were today has located, is possible?, thanks in advance!

  26. Hi Narayana Swamy Palla,

    Do you have any idea on how to achieve solve the below issue:

  27. Hi Swamy, I was wondering if you have any suggestions for flagging certain tasks (using Reporting IDs) within a Project 2010 schedule that would then show up on the Gantt. Any help would be appreciated!!

  28. I would like to do 2 tasks.
    1. Group the left chart by only main tasks, which has to cover till its sub tasks positions. Is it possible? I tried with category group of main tasks but the positions are not matching between tasks chart and main chart?
    2. Format month label to Quarter. I tried interval type is month and interval=3, but I could not format the label as Q1,Q2 etc. Can you please help me with this?

  29. Hi Swamy, is it to possible to enlarge the bars containing the task name in order to show long description? Thanks

  30. This comment has been removed by the author.

  31. Hello, Swamy. Thanks for your video and tutorial. Great tricks!

    I am, however, stuck at the task bars. Mine are a copy/paste as yours are, but the task bars are mimicking the data bar and are not filling the chart area from left to right - as yours are. I didn't see any spot that you changed anything in that area other than the gap between the bars top to bottom. Can you advise how your are filling?


  32. Dear Swamy,

    Thanks for writing such a useful post.

    But, I do have an issue which is irritating me and is as follows:

    In my case, I have many tasks (say 150) and in this case, Gantt is messing up.

    So, I have increased the Area according to number of tasks. But in other case, I have less no. of tasks (say 15-20) and in this case, each and every Gantt Bar size is becoming too huge.
    So, Is there any way to fix the size of Gantt Bars irrespective of the selection of No. of Tasks???

    Thanks & Regards,

  33. Hi Swamy,

    Thats a wonderful post. can we set up a pagination when there are too many records ?

    Thanks in Advance
    Mansura Shaik

  34. Hi Swamy, Thank you for a great post. How Do I change the years to Quarters?

  35. Hi, thank you for this post. It's very helpful.

    One concern is that if there are many records, how does the chart look like?
    Can we do paging?

  36. Amazing article mate.
    I am trying the same with XML web Service data source I getting no where.

    I have a data source of XML web services in SSRS 2008 R2

    I got the following warning

    "unknown collection member for dataset field""

    SO I tried to use CDate() that got the following error.

    [rsRuntimeErrorInExpression] The High expression for the chart ‘Chart1’ contains an error: Conversion from string "" to type 'Date' is not valid.

    But never had data shown in range chart in preview or while running the report. Any help will be great.

  37. Hi,

    is there a way to display axis label as quarters?

    For example : 2015 Q1, 2015 Q2, etc

  39. Wonderful article. currently i prepared a gantt chart that lists out activities based on start date and end date. my requirement is within each bar based on time, i should show it in different colors. Like any event starting between 8am till 2 pm should in blue, 2pm till 8pm in green and rest in any other color. something like below:
    Activity A: [*****Blue*****][******Green*****]
    Activity B: [**Blue***][******Green*****][****Yellow***]
    Activity C: [**'Green**][****Yellow***][***Blue***]
    Please help.

    1. hi shrinivas...
      have you done that report?
      I need to create similar report...

  40. Hello Sir,

    Thanks for this great article.

    I have implemented the schedule report as per your guidance. I am facing an issue. i am getting an error when the dataset size increasing from 1735.

    please suggest an approach to overcome it.

  41. Very informative, Thanks! Can we add Quarter interval type as well along with Years and Months?
