使用matplotlib

Question

我有一个从E ^ -35到E ^ -17的数据，相对于plt.arange（0,1,0.01，float）绘制

但结果出来并不像我预期的那样

它是在x = 0

处的散点图

fig0 = plt.figure()
ax0 = fig0.add_subplot( 111 )
ax0.scatter( data, np.arange(0,1,0.01, float) )
plt.show()

我的数据是

Answer 1

Matplotlib还没有能够选择线性比例来很好地匹配您的数据。由于您的x坐标数据范围很广，因此对数刻度可能更适合您：

fig0 = plt.figure()
ax0 = fig0.add_subplot( 111 )
ax0.scatter( data, np.arange(0,1,0.01, float) )
ax0.set_xlim(np.min(data), np.max(data))
ax0.set_xscale('log')
plt.show()
