plt.yscale('log') after plt.scatter() behaves unpredictably in this example. #6915
Description
As mentioned in this SE question a scatter plot is not autoscaling to include all of the data if plt.yscale('log') is used after plt.scatter(). This happens for the y-axis but not the x-axis in the example, and does not happen for plt.plot().
In an earlier answer by a developer, ax.set_yscale('log') is shown following ax.scatter(), so I am wondering if this may be a bug.
Using matplotlib version 1.5.1 and python 2.7.11
import matplotlib.pyplot as plt
X = [0.997, 2.643, 0.354, 0.075, 1.0, 0.03, 2.39, 0.364, 0.221, 0.437]
Y = [15.487507, 2.320735, 0.085742, 0.303032, 1.0, 0.025435, 4.436435,
0.025435, 0.000503, 2.320735]
plt.figure()
plt.subplot(2,2,1)
plt.scatter(X, Y)
plt.xscale('log')
plt.yscale('log')
plt.title('scatter - scale last')
plt.subplot(2,2,2)
plt.plot(X, Y)
plt.xscale('log')
plt.yscale('log')
plt.title('plot - scale last')
plt.subplot(2,2,3)
plt.xscale('log')
plt.yscale('log')
plt.scatter(X, Y)
plt.title('scatter - scale first')
plt.subplot(2,2,4)
plt.xscale('log')
plt.yscale('log')
plt.plot(X, Y)
plt.title('plot - scale first')
plt.show()
