    <p>I have a few boxplots in matplotlib that I want to zoom in on a particular y-range ([0,0.1]) using <a href="http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/users/overview.html" rel="nofollow noreferrer">inset axes</a>. It is not clear to me from the <a href="http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/examples/inset_locator_demo2.py" rel="nofollow noreferrer">example</a> in the documentation how I should do this for multiple boxplots on the same figure. I was trying to modify the code provided this example, but there was too much unnecessary complexity. My code is pretty simple:</p> <pre><code># dataToPlot is a list of lists, containing some data. plt.figure() plt.boxplot(dataToPlot) plt.savefig( 'image.jpeg', bbox_inches=0) </code></pre> <p>How do I add inset axes and zoom in on the first boxplot of the two? How can I do it for both?</p> <p>EDIT: I tried the code below, but here's what I got: <img src="https://i.stack.imgur.com/ht95r.jpg" alt="enter image description here"></p> <p>What went wrong?</p> <pre><code># what's the meaning of these two parameters? fig = plt.figure(1, [5,4]) # what does 111 mean? ax = fig.add_subplot(111) ax.boxplot(data) # ax.set_xlim(0,21) # done automatically based on the no. of samples, right? # ax.set_ylim(0,300) # done automatically based on max value in my samples, right? # Create the zoomed axes axins = zoomed_inset_axes(ax, 6, loc=1) # zoom = 6, location = 1 (upper right) axins.boxplot(data) # sub region of the original image #here I am selecting the first boxplot by choosing appropriate values for x1 and x2 # on the y-axis, I'm selecting the range which I want to zoom in, right? x1, x2, y1, y2 = 0.9, 1.1, 0.0, 0.01 axins.set_xlim(x1, x2) axins.set_ylim(y1, y2) # even though it's false, I still see all numbers on both axes, how do I remove them? plt.xticks(visible=False) plt.yticks(visible=False) # draw a bbox of the region of the inset axes in the parent axes and # connecting lines between the bbox and the inset axes area # what are fc and ec here? where do loc1 and loc2 come from? mark_inset(ax, axins, loc1=2, loc2=4, fc="none", ec="0.5") plt.savefig( 'img.jpeg', bbox_inches=0) </code></pre>

    1. COI'm not sure I know what you mean by "multiple boxplots on the same figure". Do you have multiple subplots?

    2. CONo, `dataToPlot` contains more than one sample of data, and `plt.boxplot` treats it as such: it draws as many boxplots as there are samples in its input.

    3. COSo, can't you just do another `axins=zoomed_inset_axes(ax,6,loc=2)` and set different coordinate range for this next plot?

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.
