The wxPython tutorial

The Graphics Device Interfacehttp://www.zetcode.com/wxpython/gdi/Because of the simplicity of the script, there are some magicnumbers. In reality, we would have to calculate them. In theprevious code example, we draw the years alongside the xaxis. We subtract 13 px from the x value. This is done tocenter the years over the vertical lines. It works on my linuxbox. I might not work correctly on other platforms. It mightnot work even on linux boxes with different themes. You justplay a bit with this example. Adjusting it to fit under thedifferent circumstances is no rocket science. Normally, weneed to calculate the width of the chart, the width of the textand center the text manually.Figure: A line chartNoteNote is a small script that shows several interesting featuresof the GDI. We will see, how we can create a custom shapedwindow. There are small applications that are used to takevisible notes. They work as reminders for people, that workwith computers a lot.
