Pandas: bar plot xtick frequency
提问by KLI
I want to create a simple bar chart for pandas DataFrame object. However, the xtick on the chart appears to be too granular, whereas if I change the plot to line chart, xtick is optimized for better viewing. I was wondering if I can bring the same line chart xtick frequency to bar chart? Thanks.
我想为 Pandas DataFrame 对象创建一个简单的条形图。但是，图表上的 xtick 似乎过于精细，而如果我将绘图更改为折线图，则 xtick 会进行优化以获得更好的查看效果。我想知道是否可以将相同的折线图 xtick 频率带入条形图？谢谢。
locks.plot(kind='bar',y='SUM')

You can reduce the number of thicks by setting one every nticks, doing something like:
您可以通过每个n刻度设置一个来减少厚度的数量，执行如下操作：
n = 10
ax = locks.plot(kind='bar', y='SUM')
ticks = ax.xaxis.get_ticklocs()
ticklabels = [l.get_text() for l in ax.xaxis.get_ticklabels()]
ax.xaxis.set_ticks(ticks[::n])
ax.xaxis.set_ticklabels(ticklabels[::n])
ax.figure.show()
