Description
Bug summary
The keyword argumenttransform of the method ax.plot(...) malfunctions with size of the samples greater than 1000.
For example, the following script
import numpy as npimport matplotlib.pyplot as pltimport matplotlib.transforms as transformsax = plt.gca()xx = np.linspace(0.0, 4 * np.pi, num=1001)yy = np.cos(xx)t = transforms.Affine2D().translate(10.0, 0.0).scale(2.0, 0.5)lines = ax.plot(xx, yy, transform=t + ax.transData)plt.show()Produces an expected figure
withnum=1000
and an empty figure
withnum=1001.
Code for reproduction
importnumpyasnpimportmatplotlib.pyplotaspltimportmatplotlib.transformsastransformsax=plt.gca()xx=np.linspace(0.0,4*np.pi,num=1001)yy=np.cos(xx)t=transforms.Affine2D().translate(10.0,0.0).scale(2.0,0.5)lines=ax.plot(xx,yy,transform=t+ax.transData)plt.show()
