    <p>I am using matplotlib 1.2.1 in ubuntu 13.10 64bit</p> <p>I have a function that creates and saves a plot and I am calling that function several times. However in some cases the suptitle is drawned over the old one, making a mess. I think this is related to the following question, but I didn't manage to understand the reply in that question: <a href="https://stackoverflow.com/questions/10559144/matplotlib-suptitle-prints-over-old-title">Matplotlib suptitle prints over old title</a></p> <p>My code is as follow:</p> <pre><code># ======================================================================= def plotMultivariable(scenarios_h, variables_h, region, title, filename): nvar = len(variables_h) nscen = len(scenarios_h) plt.figure(1) maintitle = unicode(title, 'utf_8') plt.suptitle(maintitle, fontsize=16, ha='center') for i in range(nvar): plt.subplot(nvar,1,i) title = unicode(variables[variables_h[i]][0], 'utf_8') ylabel = unicode(variables[variables_h[i]][1], 'utf_8') plt.title(title) plt.ylabel(ylabel) for scenario in scenarios_h: for spGroup in spAggregates.keys(): serieName = unicode(spGroup + " - " + scenario, 'utf_8') serieColor = scenarios[scenario] serieLineType = spAggregates[spGroup][2] serieWidth = spAggregates[spGroup][3] key = region, variables_h[i], scenario, spGroup y = odata[key] plt.plot(x, y, serieLineType, label=serieName, linewidth=serieWidth, color=serieColor) plt.subplots_adjust(hspace=0.6) plt.savefig(chartoutdir+"/"+filename) #plt.show() </code></pre> <p>And I call this function with:</p> <pre><code>plotMultivariable(['reference','vRegEnd075','vRegFixed','vRegFromHr'],['expReturns','vReg','vol','hV'],'11000','Management effect','management.png') plotMultivariable(['reference','withRisk06','withRisk08','withRisk10'],['expReturns','vReg','vol','hV'],'11000','Risk effect','risk.png') plotMultivariable(['nonspatial','reference','withVariance'],['expReturns','vReg','vol','hV'],'11000','Spatial explicit simulations','space.png') </code></pre> <p>Here are the resulting plots. If I view them instead of saving they are fine. Any hint or help with understandingh the reply in the cited answer? Thank you..</p> <p><img src="https://i.stack.imgur.com/n63jj.png" alt="first image (ok)"> <img src="https://i.stack.imgur.com/SrBjI.png" alt="second plot (ok)"> <img src="https://i.stack.imgur.com/uiWAl.png" alt="third plot (title overdrawn)"></p>

    1. COBy the way, you could improve the look of your labels using LaTeX formating, replacing `"Mm^3"` by `r"Mm$^3$"`.

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.
