Bars information in custom plot

[supernatural]

Hi,

I'm coding an indicator using custom plotting (overriding the Plot method) and let's say I need to draw, for each bar of the price panel, a simple rectangle in the indicator panel. For that, I need to know such things as what bars are displayed in the price panel (for example bar number 500 at position +200 pixels) and the space between each price bar. I don't see these informations in the CustomPlotSample indicator code so my question is what objects/variables can I use to obtain this kind of information?

Thanks

supernatural, this is unfortunately outside of our supported NinjaScript methods, however you can take a look at the PowerVolume indicators for example to get started (i.e. VolumeProfile).

Ok...
At least, if a user has done it, how can I just get the X coordinate of a displayed price bar?

supernatural do a search for ChartHelper in this forum. Some user posted a whole pile of methods to do with grabbing co ords and pixels that is really helpful.
The major difficulty (for me) was getting the bar index. If it's CurrentBar it is easy but historically it requires.. well you will see.

GetXByBarIdx() may also help you but NONE of this is supported....

Mindset, thanks for the help.
Yes, finally I could get the bar index by doing :
ChartControl.GetXByBarIdx(BarsArray[0], FirstBarIndexPainted)
for example for the first painted bar.
