Width of first and last bars in reporting Graph is cut in half

[David]

Using the Telerik.Reporting.Graph, how can I get the first and last bar to not be cut in half?

I have worked around this issue, but it doesn't seem quite like the proper way of doing it.

Just in case someone else comes across this issue and the "proper" way is never revealed, this is what I did:

My data is always a range such as 1-20, or 1-30. I manually set the cartesianCoordinateSystem.XAxis.Scale.Minimum to 0.65, this allowed a little space between the y axis line and the first bar.

To handle the maximum value, I left the default to NaN, but setup a binding to change the Maximum. You set the binding under cartesianCoordinateSystem, not the graph itself. The binding I used was:

Property Path : XAxis.Scale.Maximum

Expression: = IsNull(CDbl(Max(Fields.DisplayNumber)), 20) + 0.35

The IsNull wasnt really needed, but the preview in the designer was showing an error without it.

Hello David,

Based on the provided information, it seems that you are using a Numerical scale for XAxis which places the data points precisely where the tick marks are. I can confirm that the solution using bindings for changing the Maximum and Minimum properties of the Scale is the correct one.

You can also test if switching to a Category scale might bring the desired visualization of the data points - How to change the axis scale to Category.
