Multiple XAxis

[Syed Sadaqat Hussain]

Hi,

I need to create multiple XAxis depending on XAxis header and OpposedPosition.

But when I create new CharAxis and assign to serie.XAxis, it is not creating the XBindPath values labels.

It is creating the labels with 0,1,2.... but when I changed the labelmode from default to Datasource and assign datasource it is also causing problems.

Please help me how to create the multiple XAxis and it should automatically pick label from XPathBindind values. I am not using the WPF designer. I am creating chart control using C#.

Thanks,

Sadaqat

Hi Sadaqat,

The LabelSource of ChartAxis should be collection of Double, String or DateTime. It should not be any other class. So you need to calculate the Labels for Axis manually as shown in below code snippet.

Code Snippet(C#):

            List<double> _labelSource = new List<double>();

            for (int i = 0; i < _viewModel.DataCollection.Count; i++)

            {

                _labelSource.Add(_viewModel.DataCollection[i].XData);

            }

            ChartSeries series = new ChartSeries() {Type=ChartTypes.Line, DataSource = _viewModel.DataCollection, BindingPathX = "XData", BindingPathsY = new List<String> {"YData"} };

            series.XAxis = new ChartAxis() { IsAutoSetRange = true,RangeCalculationMode=RangeCalculationMode.ConsistentAcrossChartTypes,RangePadding=ChartRangePaddingType.None};

            ChartArea area = new ChartArea();

            area.PrimaryAxis = new ChartAxis() { IsAutoSetRange=false,Range=new DoubleRange(_labelSource[0],_labelSource[_labelSource.Count-1]),LabelsMode = ChartAxisLabelsMode.DataSource, LabelsSource = _labelSource };

            area.SecondaryAxis = new ChartAxis() { IsAutoSetRange = true };

            area.Series.Add(series);

            Chart chart = new Chart();

            chart.Areas.Add(area);
