Re: [Matplotlib-users] using subplot to plot a large numbers of graphs in a loop

[John H. <jdh...@ac...>]

You seem to be mixing idioms, between pylab which manages current
figure and current axes, and explicitly managing the Figure and Axes
instances yourself.  Eg

	fig = figure()
	hold(False)  #<-- manipulates current axes
	for counter in counter_list:
		y = intensities_calc[counter]
		plotnr = plotnr+1	
		ax = subplot(rownrs, colnrs, plotnr) #<-- uses current fig
		fig.add_subplot(ax) 
		plot(x,y)  #<-- uses current axes
		if ax.is_last_row():
		ax.set_xlabel('time')

If you want to manage the figure and axes attributes yourself, which
is good practice, I suggest imposing some discipline on yourself and
only importing 4 things from pylab (this is what I usually do)

  from pylab import figure, show, nx, close

Your code would then look something like:

    fig = figure()
    for counter in counter_list:
        y = intensities_calc[counter]
        plotnr = plotnr+1    
        ax = fig.add_subplot(rownrs, colnrs, plotnr)
        ax.hold(False)          
        ax.plot(x,y)    
        if ax.is_last_row():
            ax.set_xlabel('time')

That should work, as long as plotnr is incrementing like you expect it
to.
