![]() One thing to note is that if you want to pad the underline, or control the line thickness (note that the line thickness is the same for both annotations) you'll have to do it manually within the 'underline_annotation' command, but this is pretty easy to do by passing more arguments through the arrowprops dict, or augmenting the location of where the line is being drawn. ncols 2 or 1 fig,axes plt.subplots (3, ncols, sharex'all', sharey'row') axes axes.reshape ( (3,ncols)) for input in inputs. However in matplotlib 2.1.1 I have this as default behavior - and I actually don't want it. #uses an arrowprops to draw a straightline anywhere on the axis.Īnd this produces an underlined annotated sin example. 32.3k 47 109 178 Add a comment 3 Answers Sorted by: 444 Use pyplot.suptitle or Figure.suptitle: import matplotlib.pyplot as plt import numpy as np figplt.figure () datanp.arange (900).reshape ( (30,30)) for i in range (1,5): axfig.addsubplot (2,2,i) ax.imshow (data) fig.suptitle ('Main title') or plt.suptitle ('Main title') plt. I have seen on Stackoverflow that some people where asking how to have the grid lines showing in between subplots. # text isn't drawn immediately and must beĪx.annotate('', xy=(tb.xmin,tb.y0), xytext=(tb.xmax,tb.y0),Īrrowprops=dict(arrowstyle="-", color='k')) Tb = text.get_tightbbox(f.canvas.get_renderer()).transformed(f.transFigure.inverted()) fig, ax plt.subplots() ax.settitle('Different horizonal alignment options when x. ![]() So is the text centered on the point, or is the first letter in the text positioned on that point Let’s see. If you have an overall title, you can use the subplotsadjust () function to ensure that it doesn’t overlap with the subplot titles: import matplotlib.pyplot as plt define subplots fig, ax plt.subplots(2, 2) fig.tightlayout(hpad2) define subplot titles ax 0, 0.settitle('First Subplot') ax 0, 1.set. import matplotlib.pyplot as plt plt.plot(range(10)) plt.title('Center Title') plt.title('Left Title', loc'left') plt.title('Right Title', loc'right') plt. Text2 = ax.annotate("sin(x)", xy=(.7.6), xycoords="axes fraction", How to change the text alignment We specify the xy coordinates for the text, but of course, the text can’t fit on a single point. Matplotlib can display plot titles centered, flush with the left side of a set of axes, and flush with the right side of a set of axes. Text1 = ax.annotate("sin(x)", xy=(.7.7), xycoords="axes fraction") Each axes can have a title (or actually three - one each with loc 'left', 'center', and 'right'), but is sometimes desirable to give a whole figure (or SubFigure) an overall title, using FigureBase.suptitle. There are some caveats with this approach, but overall I find it quite flexible because then you can customize the underline however you'd like.Īn example of my solution is as follows: import matplotlib.pyplot as pltĪx.plot(np.sin(np.linspace(0,2*np.pi,100))) Ultimately my solution finds a bounding box for the text object in question and then uses the arrowprop arguments in the annotation command in order to draw a straight line underneath the text. This is an old question, but I actually had a need for underlining text that didn't use LaTeX so I figured I'd follow up with the solution that I came up with, for others who may encounter the same issue. ![]()
