ScottPlot is a free and open-source graphing library for .NET which makes it easy to display data in a variety of formats (line plots, bar charts, scatter plots, etc.) with just a few lines of code (see the ScottPlot Cookbook for examples). User controls are available for WinForms and WPF to allow interactive display of data.

ScottPlot 3.1.6 is the last version which supports .NET Framework 4.5

Solution files for quickstart examples are in /doc/quickstart

• Install the ScottPlot NuGet package
• Add the following to your startup sequence:

double[] dataX = new double[] {1, 2, 3, 4, 5};
double[] dataY = new double[] {1, 4, 9, 16, 25};
var plt = new ScottPlot.Plot(600, 400);
plt.PlotScatter(dataX, dataY);
plt.SaveFig("quickstart.png");

Static plots can be useful in GUI applications, such as plotting on a Picturebox:

pictureBox1.Image = plt.GetBitmap();

• Install the ScottPlot.WinForms NuGet package
• Drag/drop a FormsPlot user control onto the Form
• Add the following to the start-up sequence:

double[] dataX = new double[] {1, 2, 3, 4, 5};
double[] dataY = new double[] {1, 4, 9, 16, 25};
wpfPlot1.plt.PlotScatter(dataX, dataY);
formsPlot1.Render();

• Install the ScottPlot.WPF NuGet package
• Add <ScottPlot:WpfPlot Name="wpfPlot1"/> to your XAML file
• Add the following to the start-up sequence:

double[] dataX = new double[] {1, 2, 3, 4, 5};
double[] dataY = new double[] {1, 4, 9, 16, 25};
wpfPlot1.plt.PlotScatter(dataX, dataY);
wpfPlot1.Render();

Review the ScottPlot Cookbook to see what ScottPlot can do and learn how to use most of the ScottPlot features. Every in figure in the cookbook is displayed next to the code that was used to create it.
