Series Event Marker symbol Issue

[PKS]

Hi,

I draw a series event marker but its symbol is not smooth.
Please check the attached screen shot and provide some help.

Thanks,

Please set chart.RenderOptions.AntiAliaslevel = 4. You might have 0 or 1 there, which disables AA.

Or you ary maybe running with an old Intel GPU that doesn't support anti-aliasing in hardware at all.

Also,please confirm do we need to manually remove the series event marker from sampledataseries when it goes out side the visible chart area or is it do automatically?

By setting ViewXY.DropOldEventMarkers = true, the outscrolled markers are destroyed by the chart.

ViewXY.DropOldSeriesData does this property clear series data(plotting) and series event markers both ?

[ArctionPasi]

DropOldSeries data destroys old series data, but not markers.

DropOldEventMarkers destroys the markers, but not data.

To destroy both, enable both these properties.

When markers are set to track the data values, and series data is destroyed from marker's location the marker will disappear because there's no data to track on that position anymore. But the marker stays in the markers list.

DropOldEventMarkers is this property drop both (SeriesEventMarkers & ChartEventMarkers) ?

[ArctionPasi]

Yes.

We need to display a huge amount of markers on the chart, so instead of initializing new marker object every time can we reuse these markers ? as soon as the marker go beyond the visible chart area we reuse it by placing it in upcoming time stamp ?

i think it would definitely boost up the performance of my application.

Would you like to suggest something on this?

Happy Coding !!

It's definitely a good idea to recycle markers. You can set marker.Visible = false when it goes out of the chart, and then recycle that marker to new position and set Visible = true.

It is the optimal approach, and I definitely recommend using it
