Using the PlotColor when Drawing

[sandman]

Hello,

I put together an indicator using a Plot that shows a hash and the pricemarker for a higher SMA. For example: I can use it in a 1minute chart so it indicates the SMA20 of a 360min DataSeries. I am not interested in the actual line of that 360 SMA20. I just want to see where it's price is at. Works fine and I can adjust the color through the PlotColor.

Add(new Plot(Color.LightBlue, PlotStyle.Hash, "RoundedSMA"));
PlotColors[0][1] = Color.Transparent; // (I use this so it only shows 1 hash)

Now I would like to add a label into the chart that tells me the timeframe being used. To do that I use DrawText as follows:


DrawText("tag", false, BarsArray[1].Period.ToString(), -1, (SMA(BarsArray[1],20))[0], 0, textcolor, new Font ("Arial", 7, FontStyle.Regular),StringAlignment.Near, Color.Empty, Color.Empty, 0);

My question is whether there are any possibilities to define the textcolor through the Plot color?

Hello sandman,

The Plots[plot index].Pen.Color will have the color used for the plot. This can be supplied to the DrawText() method.

Chelsea, Thanks for the fast reply which sounds like it is possible.

The references are unfortunately limited to Plots. They do not show how the DrawText() method can pull in the Plot colors.

Is there a sample somewhere that shows more exactly how to do that (I am not a pro-programmer), or could you expand on what you said. In case it helps, I am including my indicator. This shows that currently the color has to be set twice: once for the plotting method which paints a hash and the pricemarker; and twice for the color of the label (using DrawText) and a limited horizontal line. I would want to get rid of the separate color choice and instead have it use the same color which the plot method uses.

Hello sandman,

The Color object can be supplied anywhere a Color parameter is accepted.

DrawText(string tag, string text, int barsAgo, double y, Color color)

For example:
DrawText("myText", "Some text", 0, High[0] + 2 * TickSize, Plots[0].Pen.Color);

Chelsea,

You make it sound so easy I needed to know that "Plots[0].Pen.Color" is the basic formula.

Needless to say it works like a charm. Many thanks.

Have a good day!
