TAChart Tutorial: Multiple Panes in one Chart

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. Since a second topic is included in this sample project it may be a bit difficult to catch the basic idea. So here we explain how you can do this from scratch.
