我有以下代码
p = ggplot(aes(x='DHT temp',y='temp3'), data=data)
p + geom_point(alpha=0.1, size=10) + scale_x_continuous(limits=(20,30)) +
scale_y_continuous(limits=(0,170)) + theme_bw()\
+ geom_abline(intercept=20)
我收到以下错误:
<repr(<ggplot.ggplot.ggplot at 0x607a3d0>)
failed: UnboundLocalError: local variable 'x' referenced before assignment>
