Adding a text
Magics allows the user to add of or several lines of text. The position of the text is by default above the plot, but some parameters aloow it to be moved around.
A basic html formatting can be used for colour, style, and font size.
Visualising the precipitation field
The goal of this exercise is to discover a bit more the diverse styles of visualisation offered the mcont object.
Here we will work with shading, and we will use a different technique to setup the levels we want to contourThe mtext object has to be inserted in the plot command to see the text on the result.
