Binding an observable collection

[n0kx]

I used an observable collection on a previous charting library and I'm trying to do the same with LightningCharts but I'm having a hard time finding the right calls.

Here is what I had that worked...

Code: Select all

MyDataCollection dataCollection = new MyDataCollection();

chart.DataContext = dataCollection;
((CategoryXAxis)chart.Axes[0]).ItemsSource = dataCollection;
((LineSeries)chart.Series[0]).ItemsSource = dataCollection;

I'm trying this but no luck and I'm sure I need to do something similar to .ItemSource like above, but I'm not sure what to use.

Code: Select all

MyDataCollection dataCollection = new MyDataCollection();

chart.BeginUpdate();

chart.DataContext = dataCollection;

// Not sure what to do here, but this doesn't work
// chart.ViewXY.SampleDataSeries[0].AddSamples(dataCollection, false);

chart.EndUpdate();

Any suggestions? Thanks!

Our chart does not currently support data binding. We are working on this and data binding will be included in version 7. Estimated delivery is by the end of this year.

Until then, you need to add data “manually” using methods that each series have. For example, in PointLineSeries there is AddPoints method and in SampleDataSeries there is AddSamples method. Take a look at the examples in our WPF demo application - especially the first ones under "Basic" and "Real-time monitoring". I also sent you some details in email.
