Introduction

In the tutorial TAChart Tutorial: BarSeries we had demonstrated how to create a chart with bar series located side-by-side. Stacked bars are another popular variant of bar charts where the grouped data are drawn stacked onto each other. In this way, the individual contributions and their sum can be shown within the same plot.

We'll apply this technique in this tutorial to plot the progress in generation of renewable energies during the last years.

As usual, you must have some basic knowledge of Lazarus, Object Pascal, and the key concepts of TAChart to follow the tutorial. If you have never worked with bar charts it is a good idea to look at the related tutorial explaining the side-by-side arrangement of bars.
