I take it by the lack of response this isn't possible?  I can't be the only one who's wanted a composite chart of all line charts and/or NullHandling different per line? 

Hi DmgInc,

Your approach is correct. You should add a chart layer and series for each LineChart. Then for each ChartAppearance set the desired NullHandling property. Your code should be working, just add the rest of the lines the same way.

Let me know if you have any questions.

My problem is, no line is getting drawn.  This is all I get

Ahhh thank you! That was it. So then for the rest of the lines I just have to add a series and and a layer for each, right?

Forgot to write back but I got everything working how I needed.  Thank you for your help!

Hi DmgInc,

If you have any further questions regarding the matter, please let me know.

Hello DmgInc,

A possible approach to edit the legend appearance would be to handle the ChartDrawItem event and set the size and position of each box:

    protected void UltraChart1_ChartDrawItem(object sender, Infragistics.UltraChart.Shared.Events.ChartDrawItemEventArgs e)

    {

        if (e.Primitive.Path == "Legend")

        {

            Box b = (Box)e.Primitive;

            b.rect.Width = 15;

            b.rect.Height = 15;

            b.rect.X += 10;

        }

    }

After that, you can get and position each separate label in the legend in the FillSceneGraph event like this:

    protected void UltraChart1_FillSceneGraph(object sender, Infragistics.UltraChart.Shared.Events.FillSceneGraphEventArgs e)

    {

        foreach (Primitive p in e.SceneGraph)

        {

            if (p.GetType().ToString() == "Infragistics.UltraChart.Core.Primitives.Text")

            {

                Text t = (Text)p;

                switch(t.GetTextString())

                {

                    case "Series1":

                        t.bounds.X += 50;

                        break;

                    case "Series2":

                        t.bounds.X += 50;

                        break;

                    default:

                        break;

                }

            }

        }

    }

To style the line appearance, you should create a PaintElement and add it to your Series:

    PaintElement pe = new PaintElement();

    pe.Fill = Color.Red;

    pe.FillOpacity = 150;

    devTargetSeries.PEs.Add(pe);

Please let me know if you have any questions regarding the matter.

Thanks a bunch Nikolay!

I figured out a couple of those things on my own, but the legend was still giving me trouble.  I have it work 99% of how I want it now, I have just 2 cosmetic things left that if they can't be fixed I could live with but if they can be fixed that would be great.

1) Is there a way to add some spacing between these items in the legend and also make the boxes w/the colors bigger? (Like in the screenshot I posted a couple replies ago) This is what I have now...would this be some FillSceneGraph stuff to change it?

I'd like it to look like this..

2) What are the line colors and opacity settings for these green, blue, and yellow shown here, do you know? These are the default colors when i create a line chart automatically. I've tried a few and they don't seem correct, like CornflowerBlue for the blue and GoldenRod for the yellow with opacity setting of 98

This is what I want...

This is what I'm getting

Hello Lucas,

1. To avoid overlapping title with the chart area, you could set Bounds of the ChartArea, for example:

Rectangle bounds = new Rectangle(50, 100, 300, 300);

UltraChart1.CompositeChart.ChartAreas[0].Bounds = bounds;

The second parameter passed to the Rectangle constructor is the offset from the top border of the control.

2. You can use the LineThickness property of the axes: yAxis.LineThickness = 1;

3. The legend style depends on the chart type used in the corresponding layer. So if you want a legend like in your second screenshot, you could create a new hidden ChartLayer containing, for example AreaChart. Then select the same series used for your LineChart. And after that add a legend and link it to that layer. Now the legend should  look as per your  requirement.

4. You can achieve this using code, similar to the following:

xAxis.Labels.Orientation = TextOrientation.Custom;

xAxis.Labels.OrientationAngle = 30;

If you have any questions regarding the matter, please let me know.
