Correct way to get PlotBrushes in OnRender

[davydhnz]

e.g.

PlotBrushes[0].GetValueAt(ChartBars.ToIndex).ToDxBrush(RenderTarget)

If you could provide the correct syntax, I'd really appreciate it. Thanks!

Hello davydhnz,

Thank you for your post.

Are you trying to access the PlotBrushes of another script, or access the PlotBrushes within the same script?

NinjaTrader_Gaby,

Thanks for your reply.
Same script. I have an OnRender text box which I want to change colors with the plot when I scroll the chart backwards and forwards.
So the textbox needs to get the PlotBrushes[0] color for the ChartBars.ToIndex bar.

Hello,

Unfortunately, it is not possible to get the PlotBrushes information this way. Once it is set, this information can't be read back.

One suggestion is that you could use a custom series of ints to determine the color. For example,

mySeries[0] = 1 //1 equals red

Then in OnRender you can make a condition that checks the int value of the series to determine the brush.

Please let us know if you have any further questions.
