说我在数据框中有这张桌子:
server
这会给我一个散点图:
DATE SUNHOUR YEAR
--- ---------- --------- ------
281 2018-10-09 11.1 2018
29 2018-01-30 6.5 2018
266 2018-09-24 6.2 2018
115 2018-04-26 13.4 2018
69 2018-03-11 7.3 2018
158 2019-06-08 13.7 2019
287 2019-10-15 8.5 2019
177 2019-06-27 15.9 2019
136 2019-05-17 11.5 2019
59 2019-03-01 10.1 2019
现在,当我看at the documentation时,我读到参数df.plot.scatter(x='DATE', y='SUNHOUR')
可以列名或位置,其值将用于根据颜色图为标记点着色。 / em>因此,我认为每年可以使用不同的颜色:
c
但这返回:
df.plot.scatter(x='DATE', y='SUNHOUR', c='YEAR')
我想念什么?
答案 0 :(得分:1)
根据文档:
c : str, int or array_like, optional
The color of each point. Possible values are:
* A single color string referred to by name, RGB or RGBA code, for instance ‘red’ or ‘#a98d19’.
* A sequence of color strings referred to by name, RGB or RGBA code, which will be used for each point’s color recursively. For instance [‘green’,’yellow’] all points will be filled in green or yellow, alternatively.
* A column name or position whose values will be used to color the marker points according to a colormap.
您不能只给出任何值,而只能给出颜色值的列(例如,您将给出一列值,包括“绿色”,“红色”等。
