Profile: create the Cartesian Projection

For our vertical profile, we will need :

Have a look at the Subpage Documentation and at the Axis Plotting Documentation, and try to get the 0oC grid line highlighted.

Profile: Using Arrays as Input of a Graph

Here is the list of levels, and the list of Temperature in Kelvin at each levels.

levels = [1.,2.,3,5,7,10,20,30,50,70,100,150,200,250,300,400,500,600,700,800,850,900,925,950,1000]

We can pass these arrays to Magics using the minput object . Check the Input Data Documentation for more information about the parameters.

The mgraph object can then be used to  preform the visualisation. All the parameters can be found in the Graph Plotting Page.
