How to set line thickness in Draw.Line?

[fersanmito]

Hi everyone,

I'm trying to draw a horizontal line using Draw.Line, but I can't find a way to change the line thickness. My current code looks like this:


Draw.Line(this, CurrentBar + ".VsalineDown", 1, High[1] - 1, -20, High[1] - 1, Brushes.Yellow); all it's ok

But when I try different posibilities

Draw.Line(this, CurrentBar + ".VsalineDown", 1, High[1] - 1, -20, High[1] - 1, Brushes.Yellow, , DashStyleHelper.Solid, ....


I would like to make the line thicker, but I don’t see an option to set the width.

Is there a way to increase the thickness of a Draw.Line?

If not, what is the best alternative?

Thanks in advance!

Hello fersanmito,

Welcome to the NinjaTrader forums!

Use the overload signature with the width parameter.

Draw.Line(NinjaScriptBase owner, string tag, bool isAutoScale, int startBarsAgo, double startY, int endBarsAgo, double endY, Brush brush, DashStyleHelper dashStyle, int width)

I am also including a link to a support article with helpful resources on getting started with NinjaScript and C#.

Hi thanks for your answer but the sample is not working,

// Draws a dotted lime green line from 10 bars back to the current bar
// with a width of 2 pixels
Draw.Line(this, "tag1", false, 10, 1000, 0, 1001, Brushes.LimeGreen, DashStyleHelper.Dot, 2);

https://developer.ninjatrader.com/docs/desktop/draw_line

Draw.Line(this, CurrentBar + ".VsalineUp", 0, Open[0], power*-1, Open[0], Brushes.DarkGreen, DashStyleHelper.Solid, 2);

Hello fersanmito,

You have excluded the isAutoScale parameter. You must provide all parameters for this overload signature and not leave any out.

The endBarsAgo value you are supplying 'power*-1' might not be an integer and may be double. The value you choose here must be an int (whole number with no decimal) and must be equal to or greater than 0 and less than CurrentBar.

Hi, whether positive or negative, the result is the same. The issue is not about direction, but about the line thickness in Draw.Line.

Hello fersanmito,

Supply all of the required parameters to use this overload signature.

You will have to add the isAutoScale parameter as directed.

Use a higher value for the width property for a line with a higher thickness.

Thanks so much , now is perfect !!

if ((CrossAbove(EMA1, EMA2, 1))

&& (CandlestickPattern1[0] == 0))

{
Draw.Line(this, $"EstrategiaXma_Line_{arrowCounter}", false, 1, Low[1] - 1, -20, Low[1] - 1, Brushes.Green, DashStyleHelper.DashDot, 3); // Estilo de línea (puede ser sólido, punteado, etc.)
arrowCounter++;

}

// Set 2
if ((CrossBelow(EMA1, EMA2, 1))

{
Draw.Line(this, $"EstrategiaXma_Line_{arrowCounter}", false, 1, High[1] + 1, -20, High[1] + 1, Brushes.Red, DashStyleHelper.DashDot, 3);
arrowCounter++;
