PointLineSeries performance
Hi, I would like to ask if there is any performance difference between using PointLineSeries and FreeformPointLineSeries. I need to draw lines, that have x-coordinates that go up and down and sometimes, PointLineSeries has problems with it. So I am wondering, if it is worth the effort to use appropr...

Spacing between bars
As you can see on the image, the 1 pixel space between bars is sometimes not rendered correctly. The frequency changes based on the wdth of the chart.
Is there a way to ensure the 1px gap between bars?

Re: Far ticks placement
I forgot to mention, that we use custom ticks.
It seems that custom ticks take the placement setting from MajorDivTickStyle.Alignment
Is thare a way to place the shorter custom ticks in the same way minor ticks are placed?

Far ticks placement
Hello,
we have a problem with minor ticks, that have axis.MinorDivTickStyle.Alignment = Alignment.Far;
They are aligned with minor ticks on the right, so they seem to be the same length and the length difference is on the axis side

Re: Many charts performance

Re: Many charts performance
I don't remember why we used the border, but I tried to set the actual width and height of the point and the performance is much better (4-5 seconds). The shape doesn't make any difference. Nevertheless the performance is poor also with this improvement. Is that a limitation that we cannot pass? Is ...

Hello, we are experiencing very bad performance when we display more charts (20 in this example). When resizing the container with the charts (collapsing part of the screen) freezes the UI for several seconds (up to 10 seconds). Each chart has 2 point line series with cca 3000 points. One of the ser...

Re: Dx11 support
Hi,
when I was creating the example I found the problem.
When axis Title.Text is set to null, there is a System.NullReferenceException in Arction.RenderingEngine11.dll
With dx9, it is not as problem.

Re: Custom tick grid line color
Thanks, that worked.
It would be useful to have a list of all changes for a release.

Re: InvalidOperationException when closing app
unfortunatelly that's the whole stack trace that came with the exception
The only thing I noticed is that the chart that involved in this exception uses FreeformPointLineSeries (other charts in our application don't use that). But it's just a guess, I don't know how to get a longer stack trace.
