我正在尝试绘制2个geom_line()
对应2个团队(LAN
/ SFN
):
hr_by_team_year = pandas.read_csv("simple.csv")
print ggplot(hr_by_team_year, aes("yearID", "HR", color="teamID")) + geom_point()+ geom_line()
但是我想要绘制一个这样的图表:
我的代码出了什么问题?
答案 0 :(得分:1)
如果指定参数名称(即使它们是可选的),有时也更容易调试。建议对您的代码进行此修改。
ggplot(hr_by_team_year, aes(x="yearID", y="HR", color="teamID")) + geom_line()
然后,您的下一个问题可能与x轴上的年份有关。如果您的数据只有数字年份,则上述内容可能会有效。如果它有您需要显示年份的日期,则可能需要添加以下内容:+ scale_x_date(labels='%Y')
我刚做了一个带日期的情节,我希望x轴显示每3个月左右的日期。此代码示例也可以帮助您:
ggplot(aes(x='Date', y='Price', color='Daily'), data=googleHiLoPlotData) \
+ geom_line() + scale_x_date(breaks=date_breaks('3 months'), labels='%m-%d-%Y') \
+ ggtitle("Daily Prices of Google")
最后,在研究如何执行此操作时,以下网址帮助了我:
