Way to see data value in imaging an array?

Hi! Is there a way to see data values when imaging an array, say, e.g., when holding the cursor over a point?

I found the data_browser.py example - how do I use it if I’m not using pylab.show, i.e., I’m using oo?

David,

Replace
“from pylab import figure, show” with “import matplotlib.pyplot as plt”
“fig = figure()” with “fig = plt.figure()”
“show()” with “plt.show()”

I believe that is all you need to do.
