[英]Editing the x-axis tick labels of a stacked bar graph in matplotlib
I have written code to produce a stacked bar graph that plots 192 bars of data. 我编写了代码来生成堆积条形图,绘制192条数据。 The data spans over 4 days, and each bar represents a 30 minute time period.
数据跨越4天,每个条形代表30分钟的时间段。
The graph produces 192 tick labels that overlap each other which is obviously undesirable appearance-wise. 该图形产生192个刻度标签,它们彼此重叠,这在外观上显然是不合需要的。
To fix this, I have added the following lines to my code: 为了解决这个问题,我在代码中添加了以下几行:
myFmt = mdates.DateFormatter('%d') myFmt = mdates.DateFormatter('%d')
ax.xaxis.set_major_formatter(myFmt) ax.xaxis.set_major_formatter(myFmt)
I want to have one tick label for each day, but matplotlib automatically generates unwanted, extra tick labels when my graph spans over 4 days or less. 我希望每天都有一个刻度标签,但是当我的图表跨越4天或更短时间时,matplotlib会自动生成不需要的额外刻度标签。 This problem doesn't happen when there are 5 or more days.
当有5天或更多天时,不会发生此问题。 Is there any way I can force the graph to just have only one tick for each day?
有什么方法可以强制图表每天只有一个刻度吗?
