如何更改标记边框宽度和填充宽度? [英] How to change marker border width and hatch width?

问题描述

在此散点图中标记的示例中，我将颜色设置为绿色，将边缘颜色设置为黑色，并将阴影线设置为"|".为了完全显示填充图案，我必须设置边缘颜色，但是当我这样做时，我会在标记周围得到一个非常粗的边框.两个问题:

In this example of a marker from my scatter plot I have set the color to green, and edge color to black, and hatch to "|". For the hatch pattern to show up at all I must set the edgecolor, however when I do, I get a very thick border around the marker. Two questions:

1) 如何设置此边框的大小(最好为 0)?

1) How can I to set the size of this border (preferably to 0)?

2)如何增加剖面线的宽度?

2) How can I increase the thickness of the hatch lines?

推荐答案

1. 您只需要设置 linewidth 即可控制标记边框的粗细.
2. 您可以通过重复符号来增加阴影的密度(在下面的示例中，'|' 在 R/H 窗格中重复；请注意，要获得 NW->SE 对角线必须对符号进行转义，因此需要两倍的字符才能真正将其加倍 -- '\\\\' 是密度 2 而 '||||' 是密度4).但是，我不认为影线内各条线的粗细是可控的.

1. You just need to set the linewidth to control the marker border thickness.
2. You can increase the density of hatching, by repeating symbols (in the example below, the '|' is repeated in the R/H pane; note that to obtain NW->SE diagonal lines the symbol must be escaped so needs twice as many characters to really double it -- '\\\\' is density 2 while '||||' is density 4). However, I don't think the thickness of individual lines within hatching is controllable.

请参阅下面的代码示例以生成如下散点图:

See the code example below to produce scatter plots such as these:

import matplotlib.pyplot as plt
# generate some data
x = [1,2,3,4,5,8]
y= [i**2 for i in x]
y2= [60-i**2+3*i for i in x]

# plot markers with thick borders
plt.subplot(121)
plt.scatter(x,y, s=500, marker='s', edgecolor='black', linewidth=3, facecolor='green', hatch='|')
# compare with no borders, and denser hatch.
plt.subplot(122)
plt.scatter(x,y2, s=500, marker='s', edgecolor='black', linewidth=0, facecolor='green', hatch='||||')

plt.show()
