Change color of a plot depending of it's value?

[chrille]

How can I change the color of a plot depending of it's value?

Example:

//Long signal
if (MyCalc)
MyPlot[0] = 1

//Short signal
else if (MyCalc)
MyPlot[0] = -1

else
MyPlot[0] = 0

If the value of MyPlot is 1 i want it o be green, -1 I want it to be red. If there's no signal I just want to keep the color that is stated in AddPlot(Brushes.Grey, "MyPlot").

Cheers,
Christian

Hello Christian,

Thanks for your post.

To change the color of the plot you would use PlotBrushes. Please see the helpguide: http://ninjatrader.com/support/helpG...lotbrushes.htm

Example:

//Long signal
if (MyCalc)
{
MyPlot[0] = 1
PlotBrushes[0][0] = Brushes.Green;
}

//Short signal
else if (MyCalc)
{
MyPlot[0] = -1
PlotBrushes[0][0] = Brushes.Red;
}

else
MyPlot[0] = 0
// leave to plot default grey color

Thank you, that works! Had to add a ";" though:

if (MyCalc)
{
MyPlot[0] = 1;
PlotBrushes[0][0] = Brushes.Green;
}

It only "paints" half of the "spike", it's not that important but if there's a simple solution...?

Hello chrille,

Thanks for your reply.

The code is only adding the Green or Red if the plot value is +1 or -1 and defaults to the grey color you assigned to the plot when the value does not equal either +1 or -1.

You can try adding other conditions such as testing if the previous plot value [1] was equal to a +1 or a -1 and the current plot value[0] is equal to zero then you can assign the red or green plot brushes to color the return to zero.
