Hi! I'm building an UWP app and having some issues with the bar graph.
I would like to show the value-label for each Tick instead of categoryname.
Like the example in the attached image that is from another application:
As you can see there is no Label for the bar, only labels for the tick. How do I do that in an UWP application.
Hi,
I noticed this bad effect today. My main view has 3 RadCartesianChart:
- SplineSeries (Minute)
- BarSeries (Hour)
- BarSeries (Day)
If I opened the app then navigate to previous dates in the default chart, you can see that the performance is amazing. There is actually 1440 data points. Then if I go to the day view that has like 30 data points and go back to the first chart, the performance is super bad.
In the second part of the video, I do the same exercise except I do not even navigate to previous dates, it means that the default chart has NO data in it! However, going to day chart then minute chart, the performance goes bad.
Sorry for the "spam" of bugs lately.
Thanks
Sébastien

We've got a RadCartesianChart with a BarSeries. We added the ChartTooltipBehaviour with a custom ContentTemplate. It's difficult to hover the mouse over bars with very small or zero values to get the tooltip to show, so I enabled `SnapToClosestPoint` for the tooltip. This works great for getting the tooltip to appear when hovering in the area above a bar, but if the tooltip gets rendered at a location where the mouse pointer is inside the tooltip, then the tooltip appears, disappears, appears, disappears, etc.
Has anyone else run into this issue? Anyone solved it?
