Marianne,
Does this library support line /step charts with markers
Yes, markers are supported in all line, area, scatter and bubble charts.
You can customize the color of the markers by using markerColor property. markerSize becomes zero when there is huge number of dataPoints, which you can customize by setting markerSize property. To enable zooming and panning, you can set zoomEnabled property to true.
Please refer documentation for more customization options available.
