这个问题来源于我昨天问的一个问题,这个问题让我很快找到了我的目标: Rotate transformation on matplotlib axis in subplot
我想创建一个2乘2的图形数组,其中左下角是一个散点图,另外三个是从该图投影x、y和x-y数据的直方图。最后一个柱状图是45度角的,这是我要调整的图的位置。在
目前,我有这个:
from matplotlib.transforms import Affine2D
import mpl_toolkits.axisartist.floating_axes as floating_axes
import matplotlib.pyplot as plt
def setup_axes(fig, rect, rotation, axisScale, axisLimits, doShift):
tr_rot = Affine2D().scale(axisScale[0], axisScale[1]).rotate_deg(rotation)
# This seems to do nothing
if doShift:
tr_trn = Affine2D().translate(-90,-5)
else:
tr_trn = Affine2D().translate(0,0)
tr = tr_rot + tr_trn
grid_helper = floating_axes.GridHelperCurveLinear(tr, extremes=axisLimits)
ax = floating_axes.FloatingSubplot(fig, rect, grid_helper=grid_helper)
fig.add_subplot(ax)
aux_ax = ax.get_aux_axes(tr)
return ax, aux_ax
fig = plt.figure(1, figsize=(8, 8))
axes = []
axisOrientation = [0, 0, 270, -45]
axisScale = [[1,1],[6,1],[6,1],[6,1]]
axisPosition = [223,221,224,222]
axisLimits = [(-0.5, 4.5, -0.5, 4.5),
(-0.5, 4.5, 0, 12),
(-0.5, 4.5, 0, 12),
(-3.5, 3.5, 0, 12)]
doShift = [False, False, False, True]
label_axes = []
for i in range(0, len(axisOrientation)):
ax, aux_ax = setup_axes(fig, axisPosition[i], axisOrientation[i],
axisScale[i], axisLimits[i], doShift[i])
axes.append(aux_ax)
label_axes.append(ax)
numPoints = 100
x = []
y = []
for i in range(0,numPoints):
x.append(np.random.rand() + i/100.0)
y.append(np.random.rand() + i/100.0 + np.mod(i,2)*2)
axes[0].plot(x,y,ls='none',marker='x')
label_axes[0].axis["bottom"].label.set_text('Variable 1')
label_axes[0].axis["left"].label.set_text('Variable 2')
b = np.linspace(-0.5,4.5,50)
axes[1].hist(x, bins = b)
axes[2].hist(y, bins = b)
b = np.linspace(-3.5,3.5,50)
axes[3].hist(np.array(x)-np.array(y), bins=b)
for i in range(1,len(label_axes)):
for axisLoc in ['top','left','right']:
label_axes[i].axis[axisLoc].set_visible(False)
label_axes[i].axis['bottom'].toggle(ticklabels=False)
fig.subplots_adjust(wspace=-0.30, hspace=-0.30, left=0.00, right=0.99, top=0.99, bottom=0.0)
plt.show()
它给出了:
正如您在代码中看到的,我试图用Affine2D().translate()
来改变右上角绘图的位置,但似乎没有效果。有人知道我该如何移动这个绘图,使它的x轴几乎碰到左下角的坐标轴的右上角吗?在
我还注意到右下角的情节与它应该是什么样子相比是颠倒的。它需要从上到下镜像。在
编辑2:
之前的代码图:子批次调整()将修复:
label_axes[2].invert_yaxis()
