Python ggplot旋转轴标签 [英] Python ggplot rotate axis labels

问题描述

当我尝试使用ggplot绘制时间序列时，x轴标签变得过于拥挤且彼此重叠:

when I tried to plot a timeseries with ggplot, the x axis lables became too crowded and overlapped each other:

代码是:

plot = ggplot(df, aes(x=df.index, weight='COUNT')) + \
    geom_bar() + \
    xlab('Date') + \
    ylab('Incidents') 

我尝试添加以下行

+ theme(axis.text.x = element_text(angle = 90, hjust = 1))

到情节，但是它不起作用.这条额外的行给了我错误:

to the plot, but it doesn't work. And this extra line gives me error:

SyntaxError: keyword can't be an expression
close failed in file object destructor:
sys.excepthook is missing
lost sys.stderr

任何想法这是怎么发生的，我应该如何解决?谢谢！

Any idea how this happened and how should I fix it? Thanks!!

推荐答案

(旧问题，如果将来有人遇到，请发布答案)

(Old question, posting the answer if anyone comes across this in the future)

"axis.text.x"格式用于R.将ggplot用于python时，将"axis.text.x"替换为"axis_text_x"

"axis.text.x" format is used for R. When using ggplot for python, replace "axis.text.x" with "axis_text_x"

这对我有用:

theme(axis_text_x  = element_text(angle = 90, hjust = 1))
