Indicator Plot Labels

[dibDab]

what's the recommended way to label indicator plots e.g.

Hello dibDab,

You are wanting to create something like the Add Plot Names indicator?

You can either custom render text where you would like it in OnRender(), or you can use Draw.Text() which will draw over the bars.

The <Indicator>.Plots[plot index].Name will have the plot name. The .Plots[plot index].Brush will have the color.

ok thanks, something to work on.

so Draw.TextFixed options are BottomLeft, BottomRight, Center, TopLeft & TopRight, presumably overwriting each other if more than 1

Hello dibDab,

That is correct, but you can add "\r\n" to a string to add a new line.

ok thanks again, all useful. but can I use '\r\n' to draw get plot1 & plot2 on different lines in different colors?

[NinjaTrader_ChelseaB]

Hello dibDab,

"\r\n" means return and new line.. This is not related to colors.

Yes, you can supply a brush to a draw method to specify the color.
Draw.Text(NinjaScriptBase owner, string tag, string text, int barsAgo, double y, Brush textBrush)

ok just to clarify, I can use '/r/n' to draw on 2 lines and I can use a brush to define different colours on each line?.

[NinjaTrader_ChelseaB]

Hello dibDab,

Yes, \r\n means new line.

A brush defines a single color. Each text would have its own brush.

Not quite. One color per draw object. Multiple lines of text in Draw.TextFixed will all be the same color.

[dibDab]

ok thanks but to conclude...

there is no (easy) way to do the following



would be useful if multple Draw.TextFixed could be stacked and not simply ovewritten?

e.g. Draw.TextFixed(NinjaScriptBase owner, string tag, string text, TextPosition textPosition, int linenumber)

[NinjaTrader_ChelseaB]

Hello dibDab,

The way to do it would be to use two draw fixed calls for different colors, and on one them add a new line so these are not layered on top of each other.

[dibDab]

I must have misunderstood.

string text = "myTxt/r/n" draws myTxt/r/n
string text = "/r/nmyTxt" draws /r/nmyTxt

i.e. drawing the text and the escape characters

Hi dibDab,

I think you have used the wrong slashes. Try backslashes instead of forward slashes.

Try copying and pasting from post # 4.

[dibDab]

that's perfect, thank you.

I'm probably going off topic here but if I use my indicator inside a strategy then the draw labels don't appear but they do if I just use the indicator?

Hello dibDab,

Are you calling AddChartIndicator()?
