title: WPF: update data of syncfusion chart
body: <p>I'm using syncfusion to build a chart, but my problem is that I load the window and the chart first. Then I change comboboxes on the window to set filters and afterwars I want to see the data in the chart. But I haven't found a solution to update the chart once it was created. So I just see a empty chart all the time. Any ideas?</p>
