12/13/2023 0 Comments Subplot scatter plot matplotlibBecause you are creating a 2x2 subplots, the indices are ax, ax, ax, and ax. plt.close('all') fig, ax = plt.subplots(1, figsize=(12,6)) # plot and labels sc = ax.scatter(x,y) plt.xlabel(x_name) plt.ylabel(y_name) # cursor grid lines lnx = plt.plot(,, color='black', linewidth=0.3) lny = plt.plot(,, color='black', linewidth=0.3) lnx.set_linestyle('None') lny.set_linestyle('None') # annotation annot = ax.annotate("", xy=(0,0), xytext=(5,5),textcoords="offset points") t_visible(False) # xy limits plt.xlim(x.min()*0.95, x.max()*1.05) plt.ylim(y.min()*0.95, y.max()*1.05) def hover(event): # check if event was in the axis if event.inaxes = ax: # draw lines and make sure they're visible lnx.set_data(, ) lnx.set_linestyle('-') lny.set_data(, ) lny.set_linestyle('-') lnx.set_visible(True) lny.set_visible(True) # get the points contained in the event cont, ind = sc.contains(event) if cont: # change annotation position annot.xy = (event.xdata, event.ydata) # write the name of every point contained in the event t_text("".format(', '.join( for n in ind]))) t_visible(True) else: t_visible(False) else: lnx.set_visible(False) lny.set_visible(False) _connect("motion_notify_event", hover) plt.The code for best fit line of a scatter plot has already been answered here.Īnd for the other subplots, you can just change the index from ax to other index like ax. When it is, we change the text, position, and visibility of the annotation accordingly. index: The plot that you have currently selected. import numpy as np import matplotlib import matplotlib.mlab as mlab import matplotlib.pyplot as plt import matplotlib.fontmanager as fm from mpltoolkits.mplot3d import Axes3D myfont fm.FontProperties(fname'') matplotlib.rcParams'axes. ncols: The number of columns of subplots in the plot grid. We’ll create a blank annotation and check if the mouse position is over one of the plotted points. How To Create Subplots in Python Using Matplotlib We can create subplots in Python using matplotlib with the subplot method, which takes three arguments: nrows: The number of rows of subplots in the plot grid. Adding line to scatter diagram in matplotlib with subplots 0 I have four subplots (arranged 2x2) and I want to add a line of best fit to these scatter diagrams however there is too much data to manually work it out and input it. Matplotlib is a comprehensive library for creating static, animated, and interactive visualizations in Python. Great! We know how to add and modify elements in our plot and detect the movement of the cursor. The event we receive from mpl_connect at our hover function has some valuable properties let’s try to get the XY coordinates of the mouse. 'g+-', 'r-', 'b.-', 'yo-' plt.plot (x, ycos, 'b-', linecos') linewidthlabel plt.plot (x, ysin, 'g-', linesin') plt.legend (loc'upper left', propmyfont, shadowTrue) locupperlowerleft, right, center plt. So even if some element is only displayed when a specific event is triggered, we still should define it outside of our function. Sklearm and Matplotlib, exporting a multi-subplot plot to HTML Sklearm and Matplotlib, exporting a multi-subplot plot to HTML score:0 Accepted answer I only had to use fig instead of plot to solve the problem. The idea is to draw the chart with all the elements we’ll use and then use the events to modify those elements.
