PlotPanel is a component for Lazarus to replace (more or less) the TChart component. With some modification it can also be used with Kylix, Delphi 5, 6 or 7.

This tutorial shows how to create a chart with multiple series in their own panes and with their own left axes and one common bottom axis. It was created while checking out the nice "Panes demo" which you can find in the folder components/tachart/demo/panes of your Lazarus installation.

TCustomPlot is a custom plotting component. It allows you to plot a series of points connected with line.
TFunctionPlot is a special function plotting control based on TCustomPlot.
TSurfacePlot3D is a 3D plotting control like 2D-plotting TFunctionPlot
