B5 - Chart - Index out of range

[patapata]

From the log:

1)
Chart rendering failed. There is likely a problem with a chart object's OnRender method. D2D error = 'Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index'

2)
Unhandled exception: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Reproduce it this way:

- Open new chart with some data series
- Compress the time scale to the max by moving - with pressed mouse button on the timescale - the last bar to the right chartpanel border.
Now move the last bar - with pressed mouse button on the timescale - to the left chartpanel border to make future timeline visible. Exception is raised.

See attached example screenshot.

Hello patapata,

Thank you for your post.

I was able to reproduce and I have created a video to submit to our development department.

Please let me know if you find any other unexpected behavior to report.

Until Ninja fixes this, you can stop the error by adding this at the beginning of OnRender

if (chartControl.SlotsPainted >= ((BarsArray[0].Count) - 2) )
return;

This simply checks the number of bars on the screen and drops out of OnRender if they hit the total number of bars in the chart...(ie "squeezing the chart)....
Perhaps not the most elegant solution but it seems to work.

Your rendering stops of course....but no error thrown...and everything pops back when you 'unsqueeze' the chart..

Hello,

This issue is tracked with ID #NTEIGHT-9026.

This should be corrected in Beta 7 which available for download. Please give this a try and let me if you are still able to reproduce.
