OnRender rectangles on both chart bars & panel bars

[davydhnz]

It's been a long time since I worked with panel bars and I've forgot the code. I remember seeing it a long time ago,
so apologies!

I'm using a plot in the panel bars, but I want OnRender to be able to draw in the panel and the chart.

I know to use base.OnRender(chartControl, chartScale);

but I forgot the precise settings to be able to draw on both.

Thank you in advance!

Hello davydhnz,

Rendering in multiple panels is not officially supported, but is possible using unsupported code.

Below is a link to an example on the User App Share.

Is it possible to only draw on the price bars with OnRender,
but also have the default Ninjatrader volume bars panel underneath?

I'm trying

IsOverlay = false;
DrawOnPricePanel = true;

and it refuses to draw on the chart if I have "Panel 2".
It will only draw if I put "Same as the input series"
but I want the volume bars on their own panel.

Thanks in advance.

Hello davydhnz,

Are you asking about adding a data series using Volume bars to a new panel in the Data Series window?

Are you asking about the VOL indicator?

DrawOnPricePanel only affects drawing tool objects. This does not affect custom rendering in OnRender().

An indicator is intended to only render in the panel the indicator is applied to.
We recommend using two indicators if you need to render in two panels.
However, the User App Share script I provided you a link to, uses unsupported code to render in multiple panels.

Yes,

I want to have a volume plot in a new panel which I can colour easily using non-OnRender code,
but I want to draw certain things based on the volume around the price bars using vectors... thanks for your help

Hello davydhnz,

Plots will only appear in the panel the indicator is applied to.

If the indicator is an a separate panel you can call Draw tool methods with DrawOnPricePanel true and the drawing tool objects will appear on the price panel.
If the objects are custom rendered, the supported approach would be to use two separate indicators, one applied to the price panel, and one applied to it's own panel.
It would require unsupported code to custom render in multiple panels.
