如何旋转 matplotlib 填充样式标记? [英] How to rotate matplotlib fill-style-markers?
问题描述
黑色是 matplotlib 标记 能够旋转.蓝色/橙色是 fill-style-markers,我还没有设法旋转以同样的方式.
In black are matplotlib markers that are able to rotate . In blue/orange are fill-style-markers, and I have not managed to rotate them in the same way.
这是生成图形的代码.在此版本中,未使用 t
.
Here is the code that has generated the graphics. In this version t
is not used.
import matplotlib as mpl
import matplotlib.pyplot as plt
x = [0,10,20,30,40,50,60,70,80,90]
for i in x:
t = mpl.markers.MarkerStyle(marker='o')
t._transform = t.get_transform().rotate_deg(-i)
marker_style = dict(color='b', markerfacecoloralt='orange', markeredgecolor='w', markersize=25,
marker='o' )
plt.plot(i, i, marker=(2, 0, -i), c='k',markersize=30, linestyle='None')
plt.plot(i, i, marker=(3, 0, -i), c='k',markersize=10, linestyle='None')
plt.plot(i, i+20,fillstyle='top', **marker_style)
plt.margins(0.15); plt.grid();plt.show()
我尝试没有成功:
marker_style = dict(....., marker=(3, 3, -i) )
or
marker_style = dict(....., marker=t )
or
plt.plot(i, i+20,fillstyle='top', marker=(3, 3, -i)
如果您知道并告诉我如何将它们放在一起,谢谢!使用 plt.scatter()
的解决方案也可以.
Thanks if you know and tell how to put the things together ! A solution with plt.scatter()
would be fine too.
推荐答案
我不知道是否可以使用标记或MarkerStyle来完成,文档仅指定如何填充除半的符号.您可以通过将 2 个半圆放在一起并相应地旋转它们来模仿这种行为.
I don't know if it can be done using markers or MarkerStyle, the documentation only specifies how to fill the symbol divided by half. You can mimic that behavior by putting together 2 half circles and rotating them accordingly.
import matplotlib.pyplot as plt
import matplotlib as mpl
plt.figure(1)
x = [0,10,20,30,40,50,60,70,80,90]
ax=plt.gca()
rot=0
for i in x:
HalfA=mpl.patches.Wedge((i, i+20), 5,theta1=0-rot,theta2=180-rot, color='r')
HalfB=mpl.patches.Wedge((i, i+20), 5,theta1=180-rot,theta2=360-rot, color='b')
rot=rot+360/len(x)
ax.add_artist(HalfA)
ax.add_artist(HalfB)
ax.plot(i, i, marker=(2, 0, -i), c='k',markersize=30, linestyle='None')
ax.plot(i, i, marker=(3, 0, -i), c='k',markersize=10, linestyle='None')
ax.set_xlim((-10, 110))
ax.set_ylim((-10, 130))
