This app shows how to display a plot by creating the axes programmatically before calling a plotting function. In this case, the app plots a polar equation using the
polarplot functions. When the user changes the value of a or b, or when they select a different line color, the plot updates to reflect their changes.
This example also demonstrates the following app building concepts:
Creating different types of axes programmatically to display plots that
uiaxes does not support
Calling a plotting function in App Designer
Sharing a callback with multiple components
Displaying Unicode® characters in a label
