    <p>I'm currently using Matplotlib to create a histogram:</p> <p><img src="https://i.stack.imgur.com/B0jJr.png" alt="enter image description here"></p> <pre><code>import matplotlib matplotlib.use('Agg') import matplotlib.pyplot as pyplot ... fig = pyplot.figure() ax = fig.add_subplot(1,1,1,) n, bins, patches = ax.hist(measurements, bins=50, range=(graph_minimum, graph_maximum), histtype='bar') #ax.set_xticklabels([n], rotation='vertical') for patch in patches: patch.set_facecolor('r') pyplot.title('Spam and Ham') pyplot.xlabel('Time (in seconds)') pyplot.ylabel('Bits of Ham') pyplot.savefig(output_filename) </code></pre> <p>I'd like to make the x-axis labels a bit more meaningful.</p> <p>Firstly, the x-axis ticks here seem to be limited to five ticks. No matter what I do, I can't seem to change this - even if I add more xticklabels, it only uses the first five. I'm not sure how Matplotlib calculates this, but I assume it's auto-calculated from the range/data?</p> <p><strong>Is there some way I can increase the resolution of x-tick labels</strong> - even to the point of one for each bar/bin?</p> <p>(Ideally, I'd also like the seconds to be reformatted in micro-seconds/milli-seconds, but that's a question for another day).</p> <p>Secondly, I'd like <strong>each individual bar labeled</strong> - with the actual number in that bin, as well as the percentage of the total of all bins.</p> <p>The final output might look something like this:</p> <p><img src="https://i.stack.imgur.com/UyBGD.png" alt="enter image description here"></p> <p>Is something like that possible with Matplotlib?</p> <p>Cheers, Victor</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
