[PrintDialog.PrintVisual() and Chart.UseEffects]

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");

  }

}

[Right way to add data to a scatter plot?]

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.

[Right way to add data to a scatter plot?]

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.

[Right way to add data to a scatter plot?]

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?
