How to set a Matplotlib rectangle edge to outside of specified width?
To set a Matplotlib rectangle edge to outside of specified width, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Create a new figure or activate an existing figure.
- Add an ax to the figure as part of a subplot arrangement.
- Initialize a variable line_width to set the rectangle outside of specified width. Use the variables xy, w and h for rectangle's center, width and height.
- Get a rectangle instance, with xy anchor points and its height and width.
- Get the offset transformbox instance.
- Add an artist patch, r (Step 5).
- Get the container for an OffsetBox instance.
- Add an annotation box, ab, to the container box.
- To display the figure, use show() method.
Example
import matplotlib.pyplot as plt from matplotlib.patches import Rectangle from matplotlib.offsetbox import AnnotationBbox, AuxTransformBox plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True fig = plt.figure() ax = fig.add_subplot(111) ax.plot([1, 6, 8, 6]) line_width = 7 xy, w, h = (1, 3), 2, 2 r = Rectangle(xy, w, h, fc='green', ec='orange', lw=3) offsetbox = AuxTransformBox(ax.transData) offsetbox.add_artist(r) ab = AnnotationBbox(offsetbox, (xy[0] + w /, xy[1] + w /), boxcoords="data", pad=0.52, fontsize=line_width, bboxprops=dict(facecolor="none", edgecolor='r', lw=line_width)) ax.add_artist(ab) plt.show()
