Set plot line value to EMPTY

[ttodua]

lets say, we want not to have the plot for specific bars.
Generally, I was used to just "not plot" on that OnBarUpdate, like:

if (myCondition) 
  myPlot[0] = Close[0];

so, if not `myCondition` then plot isn't being ploted/shown at all.

but how can we use in ternary operator, like this?

myPlot[0] = myCondition ? Close[0] : Double.NaN;

but on this case, it throws error (` Error on calling 'CalculateMinMax' method on bar XXX: The calculation results in unrenderable values.` )

if i use

myPlot[0] = myCondition ? Close[0] : myPlot[1];

then it plots at 0.00 on those occassions...
what is workaround?
yes, i know that i should not set value at all , or use .Reset(), but is there any value to assing to it, which will just force the chart not to shown line, as it is wasnt set at all on that bar?

hope my question is simple.

Hello TazoTodua, thanks for your post.

Instead of setting the plot value to null for ignored data points, use Reset() and only plot if IsValidDataPoint() is true. Alternatively, if you are calculating values, and some of those values can be ignored, you can set the PlotBrushes of that bar to Brushes.Transparent to hide them while plotting.

Best regards.

thanks.
so, just with NULL value (or .nan) it is not possible to make that on that bar, to become ignored?

I've not tried NULL, have tried double.nan, but it errors.

thanks!

Hello TazoTodua, thanks for your reply.

Sorry, in my last post I meant PlotBrushes, not BarBrushes.

If you don't want to plot for some values, set the PlotBrushes[0][0] to Brushes.Transparent.
