我有一個多邊形徑向圖,但是我無法弄清楚如何使圖形的其餘部分如y-tick線多邊形。Matplotlib徑向圖(極座標圖) - 子軸控制
radar.py
:
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cm as cm
from matplotlib.path import Path
from matplotlib.spines import Spine
from matplotlib.projections.polar import PolarAxes
from matplotlib.projections import register_projection
def _radar_factory(num_vars):
theta = 2*np.pi * np.linspace(0, 1-1./num_vars, num_vars)
theta += np.pi/2
def unit_poly_verts(theta):
x0, y0, r = [0.5] * 3
verts = [(r*np.cos(t) + x0, r*np.sin(t) + y0) for t in theta]
return verts
class RadarAxes(PolarAxes):
name = 'radar'
RESOLUTION = 1
def fill(self, *args, **kwargs):
closed = kwargs.pop('closed', True)
return super(RadarAxes, self).fill(closed=closed, *args, **kwargs)
def plot(self, *args, **kwargs):
lines = super(RadarAxes, self).plot(*args, **kwargs)
for line in lines:
self._close_line(line)
def _close_line(self, line):
x, y = line.get_data()
# FIXME: markers at x[0], y[0] get doubled-up
if x[0] != x[-1]:
x = np.concatenate((x, [x[0]]))
y = np.concatenate((y, [y[0]]))
line.set_data(x, y)
def set_varlabels(self, labels):
self.set_thetagrids(theta * 180/np.pi, labels)
def _gen_axes_patch(self):
verts = unit_poly_verts(theta)
return plt.Polygon(verts, closed=True, edgecolor='k')
def _gen_axes_spines(self):
spine_type = 'circle'
verts = unit_poly_verts(theta)
verts.append(verts[0])
path = Path(verts)
spine = Spine(self, spine_type, path)
spine.set_transform(self.transAxes)
return {'polar': spine}
register_projection(RadarAxes)
return theta
def radar_graph(labels = [], values = []):
N = len(labels)
theta = _radar_factory(N)
fig = plt.figure()
ax = fig.add_subplot(1, 1, 1, projection='radar')
ax.set_ylim(0,100)
ax.set_yticks([20, 40, 60, 80, 100])
ax.set_yticklabels(['','','','',''])
ax.plot(theta, values, color='k', linestyle='dashed', linewidth=.2)
ax.fill(theta, values, color='#23B5BA')
ax.set_varlabels(labels)
plt.savefig("radar.png", dpi=100)
這是我如何打電話radar.py生成圖形:
from radar import radar_graph
labels = ['1', '2', '3', '4', '5']
values = [65, 66, 53, 54, 78]
radar_graph(labels, values)
正如你可以將此圖像y軸是圓形的,但整體的看結構是一個polygon.Radar圖片:
也許有一種方法可以轉換類似刺的yticks。
快速簡單的黑客不會使用座標軸網格,而只需將網格繪製爲灰色和虛線樣式的線圖。 – ImportanceOfBeingErnest
謝謝您的重要性,我同意它不是我希望的優雅解決方案,但它很容易完成。我添加了代碼,以防有人搜索時想知道如何添加該代碼。 – Vexiis
那麼,你不是要在你的問題中提供答案。相反,您可以在回答欄中回答自己的問題。這樣問題就會有一個答案,以後可以接受。 – ImportanceOfBeingErnest
