To make transparent error bars without affecting markers in matplotlib, we can take the following steps −
Steps
Set the figure size and adjust the padding between and around the subplots.
Make lists x, y and z for data.
Initialize a variable error_bar_width=5
Plot y versus x as lines and/or markers with attached errorbars.
Set the alpha value of bars and caps.
To display the figure, use show() method.
Example
from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True x = [1, 3, 5, 7] y = [1, 3, 5, 7] z = [4, 5, 1, 4] error_bar_width = 5 markers, caps, bars = plt.errorbar(x, y, z, capsize=5, elinewidth=error_bar_width, markeredgewidth=7, fmt='o', ecolor='black', capthick=2) [bar.set_alpha(0.5) for bar in bars] [cap.set_alpha(0.5) for cap in caps] plt.show()
Output
It will produce the following output −
