Matplotlib table font size
Working with Matplotlib in Python (2.7.9). I need to build a table in a subheading (in this case, the subheading name is tab), but I cannot find a way to change the font size of the table ( http://imgur.com/0Ttvzee - bottom left). Antman is happy with the results, but I am not. This is the code I used.
EDIT: Added complete code
def stat_chart(self):
DN = self.diff
ij = self.ij_list

ocont = self.ocont
ucont = self.ucont

clat = '%1.2f' %self.mclat
clonlat = "{0}/{1}".format(clon,clat)

perim = self.perimeter
mdist = np.array(self.widths)
mdist = mdist[:,0]*10
mdist = np.mean(mdist)
pstat = self.polygon_status
if pstat == 1:
status = "Overestimation"
else:
status = "Underestimation"

table_props = the_table.properties()
table_cells = table_props['child_artists']

plt.show()
return
EDIT2: Eventually (un) solved printing text instead of table. Good enough.

According to the docs , table
has a kwarg called fontsize
float value for the size in points.
In your example above, for a 5 point font, you should use:
the_table =tab.table(cellText=stats,colWidths=cwid,rowLabels=rows,colLabels=columns,loc='center',fontsize=5)
If you need more control, you can pass an instance to a FontManager
method cell.set_text_props()
as described in this example . This will allow you to set family size, spacing, style, etc. In addition to the size.
EDIT: playing around with the Matplotlib example , it seems that simply passing fontsize
to the table has no effect. However, import
from matplotlib.font_manager import FontProperties
and then loop through cells and run
cell.set_text_props(fontproperties=FontProperties(size = 5))
has the desired effect. It's unclear why the documented kwarg fontsize
doesn't work in this (or apparently your) case.
