Forcing plots to disappear/reappear?

June 17th, 2024, 10:03 PM

I'm trying to get the indicator plots to disappear/reappear when clicking the "AVG" and "BANDS" buttons on the toolbar. It works when I manually press F5 or do "Reload NinjaScript"; however, I'd like this to be done automatically. The "ForceRefresh()" in my code does not work. I've also tried "Update()" and even "SendKeys.SendWait({F5})". How is this done? I know it's possible because indicators offered in NexusFi have done this!

One way of doing this is to alternate the PlotStyle for the relevant plot between .Line and .PriceBox
For example, on button engaged, use:

Code

                
Plots[0].PlotStyle = PlotStyle.Line;

And when button is disengaged, use:

Code

                
Plots[0].PlotStyle = PlotStyle.PriceBox;

The PriceBox style plots just a marker in the price axis. If you don't want that to show, you can apply a Brushes.Transparent color to it.

I hope this helps.
