plot([x], y, [fmt], *, data=None, **kwargs) plot([x], y, [fmt], [x2], y2, [fmt2], ..., **kwargs) 1. 2. 点或线节点的坐标由 x,y 给出。 可选的参数 fmt 是定义基本格式(如颜色、标记和线条风格)的方便方法。这是一个快捷的字符串表示法,在下面的 Notes 部分中进行了描述。
plot([x], y, [fmt], [x2], y2, [fmt2], ...,**kwargs) Parameters---x, y : array-likeorscalar The horizontal/vertical coordinates of the data points.*x* values are optional. Ifnotgiven, they default to ``[0, ..., N-1]``. Commonly, these...

Now, let’s explore how to add legends to only a specific part of a plot in Matplotlib. We can achieve this by creating multiple plots on the same axes and adding legends only for the desired elements. importmatplotlib.pyplotasplt# Create some datax=[1,2,3,4,5]y1=[1,4,9,16,25]...
only_move:字典型,用于指定文本标签与不同对象发生遮挡时的位移策略,可选择'points'、'text'和'objects',对应值可选'xy'、'x'、'y',分别代表竖直和水平方向均调整、只调整水平方向以及只调整竖直方向。 arrowprops:字典型,用于设置偏移后的文字标签与原始位置之间的连线样式。和matplotlib 的ax.annotate()使用相似...
省去了寻找shape文件的麻烦2.使用maskout.py这个模块,其中的函数shp2clip_new(originfig, ax, shpfile, clabel=None,vcplot=None)可帮助我们绘制想要的shape3.salem库,这个方法比较简单,通过.salem.roi(shape= )这个方法可以更具shape文件来筛选数据4.polygon_to_mask,可生成掩膜数组,为布尔值,可根据该布尔数组...
Theplotfunction will be faster for scatterplots where markers don't vary in size or color. Any or all ofx,y,s, andcmay be maskedarrays, in which case all masks will be combined and only unmasked points will be plotted. Fundamentally, scatter works with 1D arrays;x,y,s, andcmay be ...
使用场景: 与stripplot()类似,只是swarmplot中数据点经过了成簇处理【the points are adjusted (only along the categorical axis) so that they don’t overlap.】,是数据点不重叠的stripplot() 语法:seaborn.swarmplot(x=None, y=None, hue=None, data=None, order=None, hue_order=None, dodge=False, orien...
