Bump...anyone?

Hello barbaros,

It has to be custom rendered with RenderTarget.DrawRectangle() / RenderTarget.DrawTextLayout().

NinjaScript > SharpDX SDK Reference > SharpDX.Direct2D1 > RenderTarget > DrawRectangle()

https://ninjatrader.com/support/helpGuides/nt8/sharpdx_direct2d1_rendertarget_drawrectangle.htm

NinjaScript > SharpDX SDK Reference > SharpDX.Direct2D1 > RenderTarget > DrawTextLayout()

https://ninjatrader.com/support/helpGuides/nt8/sharpdx_direct2d1_rendertarget_drawtextlayout.htm

Included with NinjaTrader is the SampleCustomRender indicator that demonstrates custom rendering.

The bar x values come from ChartControl.GetXByBarIndex().

NinjaScript > Language Reference > Common > Charts > ChartControl > GetXByBarIndex()

Jtrealstats Realtime Level Ii / Tick Volume - NinjaTrader Ecosystem

This is a conversion of the Realtime Level II/Tick Volume. Please contact the original author for any questions or comments. Update Aug 27th, 2018: Since OnRenderTargetChanged can be called before State.DataLoaded, setting the dxmBrushes["backColor"].MediaBrush here wasn't working out and was sometimes null. Changed this to now get the chart background color (and text color) from […]

This means you need to adjust all the rectangles when the chart is scrolled since you are custom drawing it at a specific x,y?

**barbaros** · 08-16-2022, 12:05 PM

May be it can be a WPF grid, cell size is adjusted with bar width and the whole grid is moved up and down if the chart is moved or scaled?

**NinjaTrader_ChelseaB** · 08-16-2022, 12:11 PM

Hello barbaros,

The RenderScrollableObjectExample I have linked in post #3 demonstrates renderings that scroll with the chart.

I would not have any examples that use WPF grid to simulate scrolling behavior.

Sounds good. Thank you!
