为什么在 matplotlib 中调整 scilimits 不能正常工作? [英] Why doesn't adjusting scilimits in matplotlib work properly?

问题描述

我正在尝试使用以下代码绘制具有相同 scilimits 的图:

我原以为 axis='x', scilimits=(5,5) 会帮助我的 x 轴成为 10**5，但是，它产生 10**6.你能帮我找出我做错的地方吗?

I was expecting that axis='x', scilimits=(5,5) would help my x-axis to be 10**5, however, it yields 10**6.Can you please help me to figure out where I am doing wrong?

解决方案

The following solution is based on a similar post by the matplotlib wizard ImportanceOfBeingErnest ;)

Here you just apply the modification to the x-axis since the y-axis values are already below 10^6.

Please upvote the original post on the above link if you find it helpful.

from matplotlib import rc
import matplotlib.ticker 

fig = plt.figure(figsize=(8, 8))
ax = fig.add_subplot(111)

# Your data here

class OOMFormatter(matplotlib.ticker.ScalarFormatter):
    def __init__(self, order=0, fformat="%1.1f", offset=True, mathText=True):
        self.oom = order
        self.fformat = fformat
        matplotlib.ticker.ScalarFormatter.__init__(self,useOffset=offset,useMathText=mathText)
    def _set_orderOfMagnitude(self, nothing):
        self.orderOfMagnitude = self.oom
    def _set_format(self, vmin, vmax):
        self.format = self.fformat
        if self._useMathText:
            self.format = '$%s$' % matplotlib.ticker._mathdefault(self.format)


plt.plot(bbbb, aaaa, 'k*', label="$A$", markerfacecolor='none', markersize = 8)

plt.ticklabel_format(style='sci', axis='y', scilimits=(5,5), useMathText=True)

# Setting the x-axis notation as 10^5
ax.xaxis.set_major_formatter(OOMFormatter(5, "%1.1f"))
ax.ticklabel_format(axis='x', style='sci', scilimits=(5,5))

# Remaining code here
