[Matplotlib-users] colorbar() and plt.title() From: Claus - 2010-04-03 10:56 ```Hi, I've got two questions: 1) one is related to colorbar() on multiple subfigures (see code example below): how do I add a scatterplot if I wanted multiple subfigures? Or, what am I doing wrong in the second code example 2) in either of the examples, how can I increase the distance between the top of the plot (imshow) and the bottom of the title? # code example 1: this works fig = plt.figure() plt.title('Hello') plt.imshow(interpolValsRas, cmap=cm.jet, interpolation='nearest', origin = 'lower', extent=[5,95,5,95]) # , plt.scatter(measurementLoc[:,0], measurementLoc[:,1], 10, messwerte, cmap=cm.jet) plt.colorbar(); # code example 2: this works generally, but only if the second last line is commented out # Q: how do I add a scatterplot if I wanted multiple subfigures? fig = plt.figure() ax = fig.add_subplot(111) plt.title('Hello') ax.imshow(interpolValsRas, cmap=cm.jet, interpolation='nearest', origin = 'lower', extent=[5,95,5,95]) # , ax.scatter(measurementLoc[:,0], measurementLoc[:,1], 10, messwerte, cmap=cm.jet) # plt.colorbar(); plt.show() Thanks for your help, Claus ```
 Re: [Matplotlib-users] colorbar() and plt.title() From: Marius 't Hart - 2010-04-03 11:43 ```Try this: from pylab import * from numpy import * Z = random.randn(100,100) figure() subplot(1,2,1) imgHandle = imshow(Z, cmap=cm.gray) scatter(random.rand(10)*100,random.rand(10)*100) colorbar(imgHandle) title('Hello') show() By the way, I find jet a bad colormap to represent scientific data: it suggests bands in the data that aren't there and when reduced to luminance (eg. students printing/copying in black/white or in the eyes of all your colorblind colleagues) the two halves of the scale are identical, rendering all graphs completely ambiguous. ;) Claus wrote: > Hi, > I've got two questions: > 1) one is related to colorbar() on multiple subfigures (see code example below): how do I add a scatterplot if I wanted multiple subfigures?
