q1. How do I change the rollovermodifier’s vertical line to a dotted line?rolloverModifier.getVerticalLinePaint().setStyle(Paint.Style.STROKE);This source doesn’t seem to work
q2. I wonder how to display markers only on the last data of the line chart.
q3. I am wondering how to make the background transparent, how to make the grid transparent on the background.
q1. I’m not sure what Stroke style has to do with dotted pattern. I believe you should set DashPathEffect on Paint to make it dotted, isn’t it?
q2. By default it isn’t possible and would require customization of RolloverModifier. To suggest something specific I would need more information about what you’re trying to implement ( description of desired behavior, some screenshots or videos that demonstrate desired output )
q3. To do this I would suggest to create custom theme for chart. It has sciChartBackground attribute which allows to say background drawable for chart.
