以下是画图代码
import fractoolbox as ftb
# ensure fractoolbox.py is in the same directory as this notebook
import numpy as np
import pandas as pd
import mplstereonet as mpls
import matplotlib.pyplot as plt
azimuth = 180
plunge = 80
fig = plt.figure(figsize=(12, 9))
ax = fig.add_subplot(1, 3, 2, projection='equal_area_stereonet')
# plot the line
ax.line(plunge, azimuth, 'o', color='b', markersize=10)
ax.grid()
ax.set_title('My Steaply Plunging Line: 180/80', y=1.1)
plt.show()
画出来的刻度离图片太远了,要怎么调整距离呢
