To keep the figure the correct size on the screen and the fonts at the expected size. Figure.savefig() with bbox_inches='tight' and PNG output is incorrectly clipping text annotations when a dpi argument is passed. The following are 30 code examples for showing how to use matplotlib.figure.Figure().These examples are extracted from open source projects. What the heck does "screen resolution" mean here? So, instead of changing the source as above, I just kept the figure.dpi setting as the default 80, and was able to generate images with savefig() that looked like images from show(). self._wspace=wspace self._hspace=hspace self._subplot_spec = subplot_spec GridSpecBase.__init__(self, nrows, ncols, width_ratios=width_ratios, height_ratios=height_ratios) Example 8. facecolor default figure.facecolor color of the drawing background. python matplotlib plot 546 .

The choice of data mining and machine learning algorithms depends heavily on the patterns identified in the dataset during data visualization phase. The matplotlib module is used to create a figure, and we can do different types of experiment with that figure such as “changing the axis of the graph”, “changing the geometric shape”, “changing the background colour of the figure” and many more.
