I have a rather large dataset (65k point) that I am adding to a line graph. I think there is a default filter built into linegraph, which should also apply to the markers (I think). The problem is that just displaying the data is a bit slow,
but if I show markers then it becomes unusable.
I was adding markers like this:
new Pen(Brushes.LimeGreen, 1),
Size = 5,
Brush = Brushes.Red,
Fill = Brushes.Orange
Is there a way to use markers so that the performance doesnt suffer? Do I need to create my own filter to reduce the size of my dataset? What should I do?
- So as followup, I tried to write my own filter class- seemed simple enough, no data point should be displayed when the markers overlap. But there seems to be no way to add a filter to a ElementMarkerPoints graph, and even though my data is
being properly filtered on the linegraph itself, its completely pointless without filtering the markers.
I tried to use chartPlotter.AddLineGraph(), but I dont know how to add my own filter using this syntax. So then I created my own LineGraph and added it to chartPlotter.Children, but then there is still no way to filter the markers.
