Color specific region of chart with different colors

[amol]

Hi Steema Support,

We are facing one issue regarding fill multiple color in line series. We are using the Dot Net TChart version 2012.
We want to show multiple color(in specific portion like in x axis when value is from 0 to 20 the color of portion is light green when value is from 20 to 30 the color of portion is light blue and so on) similar to below chart .

Thanks in advance.

Thanks and Regards

Hello Amol,

have you had a look at the Contour series? There are several demos in the Feature Demo:

Hi Christopher,

Thanks for your quick response.
As you discussed in the earlier mail i have already gone through with it.
But in "Filled Levels" example contrours setting color like this-

this.contour1.Brush.Color = System.Drawing.Color.FromArgb(((int)(((byte)(68)))), ((int)(((byte)(102)))), ((int)(((byte)(163)))));
this.contour1.EndColor = System.Drawing.Color.FromArgb(((int)(((byte)(192)))), ((int)(((byte)(0)))), ((int)(((byte)(0)))));
this.contour1.FillLevels = true;
this.contour1.StartColor = System.Drawing.Color.FromArgb(((int)(((byte)(255)))), ((int)(((byte)(255)))), ((int)(((byte)(192)))));

but actually tchart plot in diffrent way...why?
In start color chart setting light yellow color.
In End color chart setting dark brown color.(I am relating with as we set gradient color).

Query1. But chart showing many colors, i am unable to understand this.
Query2. One more thing sir please explains steps in contour and logic behind drawing of contour means how we draw contour without using fillsamplevalues method.
Query3. Please provide dummy data for drawing contours in teechart.

Thanks in advance.

Hello Amol,

Query1. But chart showing many colors, i am unable to understand this.

Okay - the problem is also that I may have misunderstood your requirements.

First question then - is the data you want to represent in your TChart two-dimensional (X,Y) or three-dimensional (X,Y,Z)?

Hi Christopher,

Yes, We want to draw in two dimensional chart.

Yes, We want to draw in two dimensional chart.

Okay, in which case neither the ColorGrid nor the Contour series are relevant, as they are both designed for 3D data (X,Y,Z).

In which case, have you considered the SeriesBand tool?

you could add several of these between each of your line series.

Hi Christopher,

Thanks for very quick response...

Actually we have data for X,Y,Z and want to draw with contour series and the view mode 3D is false.
We can not use line series here.
So please provide solution for below queries-
Query1. But chart showing many colors, i am unable to understand this.
Query2. One more thing sir please explains steps in contour and logic behind drawing of contour means how we draw contour without using fillsamplevalues method.
Query3. Please provide dummy data for drawing contours in teechart.

Hello Amol,

Do please bear in mind that the time we have to spend with our clients is not infinite, especially when we receive no or little income for it.

Over and above the ColorGrid/Contour series examples in the Feature Demo, I think the best place to look for further examples of how to use these series is in these forums - could I please suggest you search these forums and have a look at the examples other clients have given us?

e.g. ColorGrid -> here.
Contour -> here
