SSRS bar/range chart rendering incorrectly when amount of data increases

Question

Hello,

We're experiencing some problems using a bar/range chart in SSRS. I couldn't post an RDL as this extension is not supported (nor rename it as XML and upload that), so I posted the XML for the RDL file below as a code block. Simply put it into a .rdl file in order to test the report.

The report shows the performance data for a specific machine. For every hour that has passed, the report shows a number that represents its performance. The number is located on top of a bar, and the bar's background color shows whether this was sufficient or not. The actual values are irrelevant here, I even made this easier to read by simply counting up. Also, the data has been reduced to a single machine, in an attempt to find our problem (however we didn't manage to solve it, hence this post).
So, what's wrong with the report? There is a report parameter that allows the user to select the amount of data he wishes to see. You can choose between 1, 2 or 3 days of data. If you choose only one day, everything is correct. However, when you choose 2 or 3 days, then the report starts showing the labels incorrectly. The labels are being shifted, and because of this some labels overlap, others are being placed on top of the wrong bar, and others are being left empty.

So, in other words, the amount of data seems to cause the bar chart to render incorrectly, even though the data itself should be correct. You can check the data if you run the query in the dataset. I added some screenshots in the attachments, which also show this. Perhaps stranger even is that on my colleague's system, the reports show differently, even though the data is hard-coded.

Does anyone know what we can do about this? Any help is appreciated!

Kind regards,
Stefan Adriaenssen

Answer 1

Hi @Stefan Adriaenssen
I tried a lot of things and what worked was changing the width of the Chart. If the width value is large, the labels of 2 days and 3 days will not overlap, and if the width value is small, even the labels of 1 day will overlap.
Another way is to change the type of Chart. If you change the type to Range Column, the labels will not move.
Best Regards,
Aniya
