Change Pen color, on the fly?

[tazatek]

Hi,

I've been trying something like the following:

Plots[0].Pen = new Pen(color, 4);
HA_Plot1.Set(Close[0]);

... to change the color of the plot based on certain values. I'm not getting a compile error for doing this, but the setting of the pen color is being ignored completely.

Thoughts ? I've looked at the SampleMultiColorPlot, but that uses multiple Plots. I'd rather use multiple pens instead... possible?


Thanks.

Unfortunately this is not supported.

Hi there,
I am not sure if this is possible but in manual I found this piece of code:
// Initialize method of a custom indicator
protected override void Initialize()
{
// Plots are added to the Plots collection in order
Add(new Plot(Color.Orange, "Plot1")); // Stored in Plots[0]
Add(new Plot(Color.Blue, "Plot2")); // Stored in Plots[1]
}

// Dynamically change the primary plot's color based on the indicator value
protected override void OnBarUpdate()
{
if (Value[0] > 100)
Plots[0].Pen = new Pen(Color.Blue);
else
Plots[0].Pen = new Pen(Color.Red);
}

What exactly is this doing? I understood it as tazatek described...

Just changes the color from blue to red of the primary plot of an indicator.

I am trying to do the same but getting an error message when trying to compile; "Does not contain a definition for "Pen" My code:


{
Plot0.Set(VOLMA(14)[0]);
if(CurrentBar < 1) return;
if (VOLMA(14)[0] > 100)
Plot0.Pen = new Pen(Color.Red);
else
Plot0.Pen = new Pen(Color.White);
}


Any suggestion?

Hello Pete77,

Thanks for your question.

Plot0 in your context looks to be the associated DataSeries object, not to be confused with your actual Plot.

You may refer to the publicly available documentation below for syntax on changing a Plot's color by pen and with PlotColors.

Plots Collection (example for changing color by pen is included within) - https://ninjatrader.com/support/help.../nt7/plots.htm
