Hi Stefan,

I have attached a sample project showing that.

I want the legend to show all the series data.

Any help is welcome.

Hi,

What is the status of this Product Idea - PI12060038.

Has this been incorporated in any of the release?

Hello Varun,

This Product Idea hasn't been implemented yet, but we will try to revisit it for the first version that will be shipped next year (13.1).

Hi,

I am new Infragistics and I am trying to simply plot a 2 line series on the XamDataChart and show the legend for the two series through C# programming. Unfortunately the legend doesn't come up at all. Can I know what the reason might be. I am exactly using the same code as the given in the online documentation. Below is the code I am using. I would really appreciate if you could help me with this.

Thanks.

SimpleDataCollection data = new SimpleDataCollection();
XamDataChart DataChart = new XamDataChart();
Legend leg = new Legend
{
Content = "Legend",
Margin = new Thickness(20),
VerticalAlignment = VerticalAlignment.Top,
HorizontalAlignment = HorizontalAlignment.Right
};

DataChart.Margin = new Thickness(5);
DataChart.DataContext = data;

// XAxis
CategoryXAxis xmXAxis = new CategoryXAxis();
xmXAxis.Interval = 50;
xmXAxis.ItemsSource = data;
xmXAxis.Label = "{Label}";

// YAxis
NumericYAxis xmYAxis = new NumericYAxis();

DataChart.Axes.Add(xmXAxis);
DataChart.Axes.Add(xmYAxis);

// Series
LineSeries series = new LineSeries();
series.ValueMemberPath = "Value";
series.XAxis = xmXAxis;
series.YAxis = xmYAxis;
series.ItemsSource = data;
series.Title = "Navya";
series.Legend = leg;

LineSeries series1 = new LineSeries();
series1.ValueMemberPath = "Value";
series1.XAxis = xmXAxis;
series1.YAxis = xmYAxis;
series1.ItemsSource = data;
series1.Title = "nnn";
series1.Legend = leg;

DataChart.Legend = leg;
DataChart.Legend.Visibility = Visibility.Visible;
DataChart.Series.Add(series);
this.LayoutRoot.Children.Add(DataChart);

Hello,

I have been looking into your post and I can say that you have to add the Legend object to the Visual tree as well as the XamDataChart, so I can suggest you add the following code at the end of the one you have shared:

this.LayoutRoot.Children.Add(leg);

Hope this helps you.

Thanks. That did work. But I have another problem now. The legend doesn't render over the chart like the one showed in the example. The chart and legend come as two different entities. Is there a way to render the legend over the chart.

Hello,

I can say that the Legend is separate element from the XamDataChart. In order to make the Legend render over the chart you have to add it to the Visual Tree after you add the chart and I can suggest you add the Chart and the Legend in a DockManager or Grid, so you can organize them as you want. In the Feature Browser under xamDataChart / Display – Legends / Legend Docking section there is a sample demonstrating how to place the Legend.

Hope this helps you.
