maxframe.dataframe.DataFrame.plot.line#

DataFrame.plot.line(*args, **kwargs)#

将 Series 或 DataFrame 绘制为线条。

此函数可用于使用 DataFrame 的值作为坐标来绘制线条。

参数:

x (label or position, optional) -- 允许绘制一列相对于另一列的图形。如果未指定，则使用 DataFrame 的索引。
y (label or position, optional) -- 允许绘制一列相对于另一列的图形。如果未指定，则使用所有数值列。
color (str, array-like, or dict, optional) --
每个 DataFrame 列的颜色。可能的值有：
- 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 column recursively. For instance ['green','yellow'] each column's line will be filled in green or yellow, alternatively. If there is only a single column to be plotted, then only the first color from the color list will be used.
- A dict of the form {column name : color}, so that each column will be colored accordingly. For example, if your columns are called a and b, then passing {'a': 'green', 'b': 'red'} will color lines for column a in green and lines for column b in red.
**kwargs -- 其他关键字参数请参见 DataFrame.plot()。

返回:

当 subplots=True 时，返回一个 ndarray，每个列对应一个 matplotlib.axes.Axes。

返回类型:

matplotlib.axes.Axes or np.ndarray of them
