How to use `GridSpec()` with `subplots()`

Question

There are several (example) SO posts dealing with how to use GridSpec with subplotting in general. What i am trying to achieve to no avail, is to allow the use of GridSpec with subplots, something like this, Where i can replace the actual Array and list indexes with some loop controlled index :

gs = gridspec.GridSpec(4, 1, height_ratios=[2, 2, 1, 1])        
tPlot, axes = plt.subplots(4, sharex=True, sharey=False)
tPlot.suptitle(node, fontsize=20)
axes[0].plot(targetDay[0], gs[0])
axes[1].plot(targetDay[1], gs[1])
axes[2].scatter(targetDay[2], gs[2])
axes[3].plot(targetDay[3], gs[3])

Needless to say that this code does not work, it just an example.

Rather than calling gridspec.GridSpec before subplots, you can send the kwargs to GridSpec from within your subplots call, using the gridspec_kw argument. From the docs:

gridspec_kw : dict

Dict with keywords passed to the GridSpec constructor used to create the grid the subplots are placed on.

So, for example:

import matplotlib.pyplot as plt

tPlot, axes = plt.subplots(
        nrows=4, ncols=1, sharex=True, sharey=False, 
        gridspec_kw={'height_ratios':[2,2,1,1]}
        )

tPlot.suptitle('node', fontsize=20)

axes[0].plot(range(10),'ro-') 
axes[1].plot(range(10),'bo-') 
axes[2].plot(range(10),'go-') 
axes[3].plot(range(10),'mo-') 

plt.show()
