Gradient Chart Background color

[inventor1949]

Is it possible to to make the chart background a gradient color?
I have no problem working with HTML code if that is the way to do it.

inventor1949, not per default unfortunately, but C# would offer ways to do it (i.e. google LinearGradientBrush).

[inventor1949]

Thanks that might work but where do I find the chart code?
can you point me at the right folder?

You would need to override the default Plot method to be able to use custom C# graphics, please see for example our CustomPlotSample.

How do you get the brush to instantiate?

The following produces an error.

LinearGradientBrush myLinearGradientBrush = new LinearGradientBrush();

Hi Mindset, I suggest you use Intellisense to guide you through the available overloads.

intellisense vs msdn

// Create a diagonal linear gradient with four stops.   
LinearGradientBrush myLinearGradientBrush =
    new LinearGradientBrush();
myLinearGradientBrush.StartPoint = new Point(0,0);
myLinearGradientBrush.EndPoint = new Point(1,1);
myLinearGradientBrush.GradientStops.Add(
    new GradientStop(Colors.Yellow, 0.0));
myLinearGradientBrush.GradientStops.Add(
    new GradientStop(Colors.Red, 0.25));                
myLinearGradientBrush.GradientStops.Add(
    new GradientStop(Colors.Blue, 0.75));        
myLinearGradientBrush.GradientStops.Add(
    new GradientStop(Colors.LimeGreen, 1.0));

The above comes straight out of msdn - I see that intellisense is giving me various arguments to complete - so how do lines 1 and 2 compile. Is msdn incorrect??

Per default you have the Drawing 2D namespace added for using, so you would need work with this instructions then - http://msdn.microsoft.com/en-us/libr...ientbrush.aspx

It's a different story according to MSDN docs if you were using the one from the Media / Presentation core one...

Aha - didn't know there were 2 types of lingradient brush - thanks for pointing that out.

Chart Background Using a Gradient Color

Hello. Would you happen to have the code to paint the background chart color as a gradient? If not, can you point me to the URL for the CustomPlotSample?

My goal is to have the code that paints the chart background as displayed in the attached *.png.

Thanks,
R. C.

Unfortunately I wouldn't have a complete sample for your task, but the CustomPlot one is default with NT per default as indicator.

Background gradient

As my golf was rained off....

Edit - see later post (#17) for zip file which is compatible with both 6.5 and 7

Hello Mindset,

Thank you for the code. I've got one question.

I'm currently running NT V6.5.1000.9. When I try to IMPORT BackGroundGradient.zip I receive the following message ..

"Import failed. NinjaTrader could not decompress the NinjaScript Archive File: Version required to extract this entry not supported(45)."

Have you seen this error before?

[Mindset]

Yes

Copy and paste the attached code into a new indicator that you make in 6.5 called BackGroundGradient and see if it will compile.

I'm getting a compile error on the following lines :

[GridCategory("Text & Colors")]

The type or namespace name 'GridCategory' could not be found (are you missing a using directive or an assembly reference?) Code : CS0246

Do you have an additional DLL that contains the GridCategory reference?

P.S. When I comment out the "GridCategory" lines, everything works great.

Thanks again.
