Chart.OnChartScroll callback for mouse wheel or slider scrolled chart?

[SmartArtsStudio]

[SOLVED]
Sorry it was the logic I was using to calculate the labels X coordinate that created the illusion OnRender was not being called.

I discovered chartControl.CanvasLeft chartControl.CanvasRigh for the X coordinate. Working as expected.


Hello

I would like some drawing (tool) object's OnRender method to be called when mouse wheel or slider scrolls their chart?

I have labels for price level lines I want to remain rendered against the chart view port left or right edges regardless of where the chart is scrolled.
They currently work as desired if I manually move the line. But they do not update when the chart is scrolled, they remain in their last OnRender-ed position..

ChartStyle.OnRender event? (Because obviously the bars re render on scroll)

How is this achieved?

Thanks

Hello SmartArtsStudio,

Glad you were able to work out a solution.

As a tip our first suggestion is to start simple and use prints outside of any conditions when engaging an issue.

Any interaction with a chart, clicking on, scrolling, zooming, changing the scale, etc, will all trigger OnRender().
