SeriesEventMarker performance
Posted: Tue Apr 14, 2020 2:01 pm
We're having issues with chart performance when there are a lot of serieseventmarkers (between 10 and 15 thousand)
Our chart displays stock prices and creates a marker when a large trade is detected. These markers are displayed as circles and the radius of the circle depends on the size of the trade that was detected. We also use the mouse interaction of the markers to display information about the trade when the user hovers the mouse over it.
At the end of the trading day when the chart shows all data it's almost not responding anymore. When removing the markers the chart response is back to normal.
Is there any other way to achieve the same functionality without using markers?
For an example see the attached image (top panel is showing price chart including markers - blue/red indicators)
