Where can I find the date that my evaluation license expires? Wally

I could not get my chart to print. I narrowed it down to the Chart.UseEffects property. In the following, when UseEffects is false, the chart does not print. When UseEffects is true, the chart prints. using System; using System.Windows; using System.Windows.Controls; using System.Windows.Input; using ChartFX.WPF; class Program { [sTAThread] static void Main(string[] args) { bool isPrintSuccessful = false; Window w = new Window(); Chart c = new Chart() { UseEffects = isPrintSuccessful }; w.Content = c; // ctrl-p to print w.CommandBindings.Add(new CommandBinding(ApplicationCommands.Print, OnPrint)); new Application().Run(w); } static void OnPrint(object sender, EventArgs e) { PrintDialog dlg = new PrintDialog(); if (dlg.ShowDialog().Value) dlg.PrintVisual(sender as Window, "My Chart"); } }

Another thing I learned that maybe helpful to developers... you don't have to use a Scatter plot to use X-Y data. The Line plot can also plot X-Y data.

Figured it out. Here is what I was missing: 1. SeriesAttributes has both a BindingPath and BindingPathX. 2. I had Visibility.Collapsed my markers for my Line plot. When I switched my chart from a Line plot to a Scatter plot, nothing was displaying because my markers were still Visibility.Collapsed.

I found examples that showed using chart1.Data[0,0] = 3.14 as a way to populate data for an XY scatter plot. But this requires adding data points one at a time. Is there a way to populate a scatter chart using SeriesAttributes.ItemSource? My thoughts were perhaps binding to List<double[]> where double[0] is the X value and double[1] is the Y value. I also considered binding to List<MyValues> where MyValues has properties X and Y. I cannot seem to find the right way to do this. Any suggestions?
