Screen rendering not working with multiple dataseries

[love2code2trade]

i am testing some ideas to see how various indicators work and i have run into an issue. when i am working with multiple dataseries and plots, all the plots dont render initially. however, when i go into a dialog box and adjust an unrelated property like autoscale or pricemarker, the lines render on the chart. any idea what might be going on? here is my code for the test:

Hello love2code2trade,

Thanks for your post.

I do not see where you are adding additional secondary data series in the code you shared. To clarify, are you referring to running the custom NinjaScript indicator on multiple charts, each set to a different data series?

So I may accurately assist, please send me the steps you are taking to reproduce the behavior and a screenshot demonstrating the behavior you are reporting.

• To send a screenshot with Windows 10 or newer I would recommend using the Windows Snipping Tool.
  • Click here for instructions
• Alternatively to send a screenshot press Alt + PRINT SCREEN to take a screenshot of the selected window. Then go to Start--> Accessories--> Paint, and press CTRL + V to paste the image. Lastly, save it as a jpeg file and send the file as an attachment.
  • Click here for detailed instruction

Also, please provide an exported copy of the indicator so that I may test it on my end using the steps you provide.

To export a NinjaScript indicator, go to Tools > Export > NinjaScript AddOn.

I look forward to assisting further.
