Tkinter is not a graphing tool. However, should you need to draw graphs with Tkinter, you can use the Canvas widget to draw graphs.
In this iteration, we will draw the following graphs:
- Pie chart (8.02_pie_chart.py)
- Bar graph (8.03_bar_graph.py)
- Scatter plot (8.04_scatter_plot.py)
The three graphs show up as follows:
Let's look at the pie chart first. You can easily create a pie chart in Tkinter using the Canvas widget's create_arc method.
The create_arc method has the following signature:
item_id = canvas.create_arc(x1, y1, x2, y2, option, ...)
Point (x1, y1) is the top-left corner and point (x2, y2) is the bottom-right corner of the rectangle into which the arc fits. If the bounding rectangle is a square, it makes a circle. The method also takes two arguments, named start and extent, which we will use to create the pie chart.
The start option...
