Updating drawing made using OnRender RenderTarget

[eladlevi]

Hi There,
I'm trying to have a calcuation that is cross bars e.g. total volume when I'm in range of X ticks.
While I do it using On Bar Update and the drawing object is given a key / tag -- and this enables me to use the same tag to update it, When I using OnRender drawing (e.g. RenderTarget.DrawText) I can't delete / overide the current drawing with new data.
Any help or ideas will be great.

as footnote, I would like to use OnRender since it is the right way to do it and the drawing there is much more flexible.

Thanks!
E.

Hi Brandon,
Thanks for replying,
let me see if I understand the limitations - In case I would like to have the draw a cycle with a text inside saying the total volume of last X bars.
I would like to have the cycle "moving" and to be painted on top of the latest bar.
Does this not achievable using OnRender drawing?

Thanks again E.

Hi Brandon,
This was my first approch (I guess I'll go back using it) , I think this approch is easier but has less flexability in the look & feel for the drawing.

Thanks,
E.
