custom bar types

[pjsmith]

Hello,

I have an indicator that plots text based bar types. I turn the actual NT generated bars off (set them transparent). The issue is that scaling is not always good. I also want to now get a little graphical. I think I need to build my own bar type. This would also probably be more efficient that adding the 1000's of text/drawing objects to the chart I do now.

Is there an example of how to build a custom bar type. I did look around and search as I believe I've seen an official one before, but I cannot find it now.

My bars are ladder type charts, so mainly text. I want to add some graphical boxes too. If there is any more efficient way you'd recommend I do this, please let me know.

Thanks.

Hello pjsmith,

Thank you for your patience.

To create your own custom bar types, you must understand the BarTypes class as well as the ChartStyle class. The BarsType class allows you to manipulate, organize, and present data that will eventually be drawn to your chart with a ChartStyle class. The ChartStyle class does the actual drawing to the chart and are where you will use SharpDX objects to render bars, and whatever else you would like to accompany the bars (like text).

You may browse the source code of BarsType and ChartStyle by opening a NinjaScript editor, and on the right, in the folders list, there are folders named BarsTypes and ChartStyles.

To fully understand SharpDX and how the rendering works and I recommend you look at the SampleCustomRender file inside of the Indicators folder.

Drawing on the chart will take place in OnRender() within your ChartStyle class.
