How to display different colors of each point without using a PolarEvent Marker
Posted: Mon Sep 23, 2019 12:08 pm
Hello?
First, I am sorry for my poor English.
I am developing a Polar Chart using ViewPolar.
However, there was a problem.
I want to change the color of the area in Sector as shown below.
There is no big problem in recognizing the data in the Sector.
By referring to the Scatter Points Selection in the demo application, the PolarEventMarker was created at the data location within the sector. And changed the color of the generated PolarEventMarker.
There was no problem when using less data. But my program has to display up to 65536 data.
More data in sectors increases the number of PolarEventMarkers to be created.
In this case, I face a performance problem. So I'm going to change the way I develop.
I set the PolarSeriesPoint value.
Set the set PolarSeriesPoint to Points on the PointLineSeriesPolar.
PolarSeriesPoint can set each value, but not color.
I can change color in PointStyle of PointLineSeriesPolar. However, all of PointLineSeriesPolar's points color changes.
Is there a way to color each point without using the PolarEventMarker?
Or, even with the PolarEventMarker, Is there a way to display 65536 PolarEventMarkers without performance issues?
Could you let me know if there's anything I don't know?
I attach a picture so that you can understand my question.
This is a picture of my application.
In the above cases, the data are all the same location. However, there are other cases in my software.
The picture below is an example.
I hope my intentions are well conveyed.
I know you're busy, but thank you for your time.
