Completing the Graph

Let us conclude this tutorial with Figure 3-11. This graphic has been generated by adding a third and a forth layer to the graph shown in Figure 3-10. The bottom axis ticks and title of layer 1 (upper graph) have been switched off. Due to the fact that both graphs show the same size as well as the same x scaling, it is sufficient to have x axis ticks and title only for the lower graph. The grids serve as a guide to the eye.

Layers 3 and 4 exhibit obviously the same size as layers 1 and 2. The only parameter that is different is the top offset of these two layers.

The graph in Figure 3-11 is left as an exercise for you. After having made the first two layers, it should not be too difficult to generate the second graph as well. Having finished your work, you may save it as "tutorial3.sg".

You still don't have enough? Well, then we will meet at tutorial 4. There, you will learn how to do some calculations with the columns of a worksheet.
