Need information on multiple charts superimposed.

[satyajit]

I was using this code snippet to generate multiple chartseries on the same chart. have attached the jpeg file. We recently got a licensed copy of sync fusion and I can no longer do this. I have attached the image with before and after charts for the same value. Many classes are obsolete in the new version and I don't know how to generate this chart.
Thanks,
Satya

//the two params are nothing but a set of x and y values.this code was working fine with a version of syncfusion a month ago

public void adddatafromcollection(TrajectoryParentFillList pFillLst, TrajectoryPointList pointLst)
{

//chart 1 data
ChartBindingData bindingdata = new ChartBindingData();
bindingdata.BeginInit();
bindingdata.XPath = new String( new char[]{'X'});
bindingdata.YPaths = new string[] { "Y" };
bindingdata.Source = pointLst;
bindingdata.EndInit();
Binding binding = new Binding();
binding.Source = bindingdata;
BindingOperations.SetBinding(chartseries, ChartSeries.DataProperty, binding);
BindingOperations.SetBinding(chartseries2, ChartSeries.DataProperty, binding);

//chart 2 data
ChartBindingData bindingdata1 = new ChartBindingData();
bindingdata1.BeginInit();
bindingdata1.XPath = "X" ;
bindingdata1.YPaths = new string[] { "Y" };
bindingdata1.Source = pFillLst;
bindingdata1.EndInit();

binding1.Source = bindingdata1;
BindingOperations.SetBinding(chartSeriesPFills, ChartSeries.DataProperty, binding1);

Hi Satya,

Sorry for the inconvenience. Recently we have revised our databinding methods for ChartSeries in order to provide the users with the easily ways to bind data.

Previously we had ChartBindingData class as a helper class to bind the data to ChartSeries. With this feature, ChartSeries can be directly bound to ObservableCollection, XML data, IList, LINQ results, CollectionViewSource and so on.

Following properties has been implemented to accomodate this feature.

DataSource - A new property has been implemented to directly bind the data from any type of source such LINQ results, ObservableCollections, CollectionViewSource, IList collections etc.

BindingPathX – A string property used to specify the path from where values should be picked for X axis.

BindingPathsY – A string[] property used to specify the path of the Y values in the source.

Sample in the following location illustrates the new DataBinding concepts of Chart WPF.

With regards to the issue mentioned in your attachment, IsIndexed property of the line series is set to true by default. You can overcome this by having IsIndexed property set to false exclusively. The following lines of code can be used to change the IsIndexed property of a chartseries.

C# Code:

chartseries.IsIndexed = false;

Still if you encounter this issue, kindly update us with a sample so that we can help you overcome the issue.

Thanks for your interests in Syncfusion products.

Please let us know if you have further queries.
