ScottPlot 5.0.16

ScottPlot is a free and open-source plotting library for .NET that makes it easy to interactively display large datasets.

The ScottPlot Cookbook demonstrates how to create line plots, bar charts, pie graphs, scatter plots, and more with just a few lines of code.

Quickstart

double[] dataX = { 1, 2, 3, 4, 5 };
double[] dataY = { 1, 4, 9, 16, 25 };

ScottPlot.Plot myPlot = new();
myPlot.Add.Scatter(dataX, dataY);
myPlot.SavePng("quickstart.png", 400, 300);

Windows Forms Quickstart

Install the ScottPlot.WinForms NuGet package, drop a FormsPlot from the toolbox onto your form, then add the following to your start-up sequence:

double[] dataX = { 1, 2, 3, 4, 5 };
double[] dataY = { 1, 4, 9, 16, 25 };

formsPlot1.Plot.Add.Scatter(dataX, dataY);
formsPlot1.Refresh();

Plot in the Cloud

ScottPlot does not require a GUI so it can be used to create plots in cloud applications. The images below are regenerated hourly using Azure Functions to update star metrics from the GitHub API and download count from the NuGet API. The data is plotted with ScottPlot and saved as an image file in blob storage. Try it out!

Try it out! Give us a star and come back in an hour and your name will appear here:
