Drawing object at the bottom of the price panel chart

[orenytz]

Hello
I was adding 3 array to build colored bar at the bottom of the price panel chart.

AddPlot(new Stroke(Brushes.Red, DashStyleHelper.Solid, 20), PlotStyle.Square, "RTDownTrend");
AddPlot(new Stroke(Brushes.Gold, DashStyleHelper.Solid, 20), PlotStyle.Square, "RTNoWhere");
AddPlot(new Stroke(Brushes.Green, DashStyleHelper.Solid, 20), PlotStyle.Square, "RTUpTrend");

RTUpTrend[0] = 1; ...

but when it draws the object it drwas on Price 0 and distroy the scale of the chart.
How can i position the built bar on the bottom of the chart without changing the chart scale?





Thanks
Oren

Hello Oren,
Seems like you're placing your indicator on Panel 1 itself, you can use new panel for your indicator & keep DrawOnPricePanel = true; so your draw objects are on proce panel & your plot are in panel 2 & your scaling will not be affected. Hope it helps!

Hello Oren, thanks for your post.

You would need to use SharpDX in the OnRender method to draw objects on the chart panel without the scaling getting messed up. The ChartPanel object contains the coordinates of the chart panel that you can use to draw graphics in OnRender.

There is also an example indicator called "SampleCustomRender" for a working reference sample.

s.kinra - this code is from starategy (not from an indocator).
i tried to implement the code from indicator - i did use DrawOnPricePanel = true;
if i load the indicator from GUI it positions well on price panel but when i try load it from strategy by AddChartIndicator it lost its scale as looks above.
Chris L - wow i looked at the manual looks like somthing complex i will back to it later after finishing critical blocks at my strategy.

Thanks alot for both of you!
