Finding the pixel distance between 2 bars

[Shai Samuel]

Is there a way to transform the distance between bars (or time) to chart pixels?

I have 2 vertical bars I draw, and I would like them to be one next to the other. I use the time to set their position, but when the chart is scaled, they may be too close or too far. I am looking for a way to calculate the difference I would like to set them up according to the X scale.

Assuming this can be done, I would need to force an update of only this calculation. My guess I need to get this information from onRender and save the last value.

By the way, I am not drawing using onRender(). Instead, I do all my drawing from onBarUpdate().

Hello Shai Samuel,

Thanks for your post.

ChartControl.Properties.BarDistance will give the pixel distance between bars. Using Drawing Tools in OnBarUpdate() will draw by bar slots and cannot be placed at specific pixel locations. If you would like to draw at specific pixel locations, OnRender() should be used with your own SharpDX rendering. Our SampleCustomRender example indicator can be used as reference for using OnRender, and I have also included resources on using SharpDX for custom rendering. Pixels will be relevant to the ChartPanel owned by the indicator.
