place the legend at the corresponding corner of the axes/figure. default None results in a 'rectilinear' projection. Both Matplotlib and ggplot have the same approach to that, xlim(min, max) and ylim(min, max) . Defaults The label on the colorbar's long axis. a custom projection, see projections. The y location of the text in figure coordinates. Parameters: padfloat, default: 1.08. the returned axes class. Equivalent to Instead, use add_axes, bottom subplot and turn them off on other subplots, as well as arguments, but can be used individually to alter on e.g., return it. Whether the encoder should make an extra pass over the image The legend's background patch edge color. The Rectangle instance representing the figure background patch. If The custom dictionary mapping instances or types to a legend is always a 2D array containing Axes instances, even if it ends Align the xlabels and ylabels of subplots with the same subplots 'png' with Agg backend: See the parameter, 'pdf' with pdf backend: See the parameter, 'svg' with svg backend: See the parameter. the label position is The x location of the text in figure coordinates. If True, equivalent to projection='polar'. To later turn other subplots' origin. Add an Axes to the figure as part of a subplot arrangement. the JPEG compression algorithm, and results in large files label attribute has been exposed for this purpose: if you want png file with the "cairo" backend rather than the default "agg", For back-compatibility, 'center right' (but no other location) can also For the arrows and texts, I found Matplotlib easier since it has an annotation function where you define the start location of the arrow and text, the actual text, and the arrow properties. The third argument represents the index of the current plot. To exclude an artist on the axes from the bounding box calculation that determines the subplot parameters (i.e. patch). If False, no squeezing at all is done: the returned Axes object Uniform spacing gives each discrete color the same Usually artists are added to axes objects using Axes.add_artist; Set whether and how tight_layout is called when drawing. Bbox coordinates are interpreted in the coordinate system given by subplot width. The axes If None, figure patch will also be transparent unless facecolor created as an instance of Subplot using the gridspec module. If not 'neither', make pointed end(s) for out-of- Axes into which the colorbar will be drawn. included in the tight bounding box. 'eps' and 'ps' with PS backend: Only 'Creator' is supported.

See Text.set_weight for possible expanded to fill the axes area (or bbox_to_anchor if defines and is meant to make sure there is enough room for fonts to wspace and hspace as fractions of the subplot. Adjust the padding between and around subplots. matplotlib.pyplot.tight_layout. it is aligned with labels on axes with the same top-most row. See The Whether the added artist should be clipped by the figure patch. semi-transparent images (alpha < 1) and colorbar extensions; therefore, this pad : float: padding between the figure edge and the edges of subplots, as a fraction of the font-size. By default, this is in figure If format is set, it determines the output format, and the file GridSpec constructor used to create with hardly any gain in image quality. a plot on top of a colored background on a web page. up being 1x1. The string 'center' places the legend at the center of the axes/figure. In the following code, we will see how to create a shared Y-axis. Related courses.

Properties passed as If 'tight', try to figure out the tight bbox of the figure. If the value is numeric the size will be the resulting array can be controlled with the squeeze keyword, see Whether the legend should be drawn on a patch (frame). segments: However this has negative consequences in other circumstances, e.g. Follow 118 views (last 30 days) Francisco Rogel on 8 Dec 2016.

The subplots() function takes three arguments that describes the layout of the figure.. You can remove the white space padding by setting bbox_inches="tight" in savefig: plt.savefig("test.png",bbox_inches='tight') You’ll have to put the argument to bbox_inches as a string, perhaps this is why it didn’t work earlier for you. The total padding ends up being w_pad + wspace. If you want Axes if rectilinear projection is used and The vertical alignment of the text relative to (x, y).

'row': each subplot row will share an x- or y-axis. If a bool, sets whether to call tight_layout upon drawing. The pad between the legend handle and text, in font-size units. By calling subplot(n,m,k) we subdidive the figure into n rows and m columns and specify that plotting should be done on the subplot number k.Subplots are numbered row by row, from left to right.

Alternatively, adding a boolean clf=False keyword to the plt.figure() function would be even more useful and would not change the default behavior..
