How to fill two plots with a color

[cmtjoancolmenero]

I'm creating an indicator and adding two SMA
AddPlot(Brushes.Red, "test1");
AddPlot(Brushes.Green, "test2");

Is there any way to fill these space and chose a color for it?

Let's say I have two lines like
-------------------------------------------
(I want to fill this with a color)
-------------------------------------------

Hello cmtjoancolmenero,

Yes, this is possible with Draw.Region().

Below is a link to the help guide.

https://ninjatrader.com/support/helpGuides/nt8/draw_region.htm

For example:
Draw.Region(this, "myRegion", CurrentBar, 0, Values[0],Values[1], null, Brushes.Blue, 100);

Hello ChelseaB,

Thanks this works, but the thing is I'd need to save the rest of the colors drawn, for instance I have a check for instance
if(condition)
{
PlotBrushes[0][0] = Brushes.Yellow;
PlotBrushes[1][0] = Brushes.Yellow;
}
else
{
PlotBrushes[0][0] = Brushes.Blue;
PlotBrushes[1][0] = Brushes.Blue;
}

Then I want when changing these plotBrushes, change it's region inside too, but from now is not working I want to draw the region when if (condition) to
Draw.Region(this, "myRegion", CurrentBar, 0, Values[0], Values[1], null, Brushes.Yellow, 10);
and in the else would be
Draw.Region(this, "myRegion", CurrentBar, 0, Values[0], Values[1], null, Brushes.Blue, 10);

but is not working, I've tried to add a different id but neither, what I'm missing?

Hello cmtjoancolmenero,

You would need a new region object with a unique tag name for each region you want as a different color.

You may find this indicator on the User App Share helpful as it adds a new region object with a different color on each crossover.

Hello ChelseaB, I've tried with unique tag name but still doesn't work, maybe I'm missing something.

I have two plots and I'm changing its color using
PlotBrushes[0][0] = Brushes.Lime;
PlotBrushes[1][0] = Brushes.Lime;

And
PlotBrushes[0][0] = Brushes.Red;
PlotBrushes[1][0] = Brushes.Red;

Now whenever I try to fill this two lines it's only painting in red even if I do this

if (someCondition)
{
PlotBrushes[0][0] = Brushes.Lime;
PlotBrushes[1][0] = Brushes.Lime;
Draw.Region(this, "ChannelFilled" + CurrentBar, CurrentBar, 0, Values[0], Values[1], null, Brushes.Lime, 56);
}
else
{
PlotBrushes[0][0] = Brushes.Red;
PlotBrushes[1][0] = Brushes.Red;
Draw.Region(this, "ChannelFilled"+CurrentBar, CurrentBar, 0, Values[0], Values[1], null, Brushes.Red, 56);
}

Values[0][0] = MySeriesDouble[0];
Values[1][0] = MySeriesDouble2[0];

Doing this, is always painting Brushes.Red, what I'm missing?

Edit
------
I think I know what I was missing on my logic, now I'm storing the startBar I want to start printing depending on the someCondition for example

condition1StartBar = -1
condition2StartBar = -1

if(condition1)
{
condition1StartBar= CurrentBar;
condition2StartBar= -1;
}
else {
condition1StartBar= -1;
condition2StartBar= CurrentBar;
}

Now, I want to print using this :

if(condition1) {
//some logic
if(condition1StartBar != -1) {
Draw.Region(this, "example" + condition1StartBar, condition1StartBar, CurrentBar, Values[0], Values[1], null, Brushes.Lime, 56);
}
}
else {
if(condition2StartBar != -1) {
Draw.Region(this, "example" + condition2StartBar, condition2StartBar, CurrentBar, Values[0], Values[1], null, Brushes.Lime, 56);
}
}


But even using this is not working... I want to start printing from the CurrentBar I've stored until the CurrentBar.

Hello cmtjoancolmenero,

The example I have provided you demonstrates this.

On line 570 to 575 the condition is a crossabove. When the condition is true the savedUBar is assigned to the bar number the condition occurred on and sets CrossDetect to 1 to indicate a cross above has occurred.

On lines 586 to 589, if the CrossDetect is 1, the region is drawn using the bar number of the object as the unique tag, and draws from the number of bars ago the condition was true on (CurrentBar - savedUBar + 1) to 0 bars ago.
