How to make markers on lines smaller in matplotlib?
提问by Sibbs Gambling
The documentation on matplotlibmarkers hereteaches me I can have several styles of the markers. For example, I may have '-o'for circles on the line, '-*'for stars on the line and '-s'for square on the line.
matplotlib此处有关标记的文档告诉我，我可以拥有多种样式的标记。例如，我可能有'-o'直线上的圆圈，直线'-*'上的星星和直线'-s'上的正方形。
However, they all appear to be too big for me. Like, when I do
但是，它们对我来说似乎都太大了。就像，当我做
axes.errorbar(x, y, yerr=ci, fmt='-o', color='k')
I get
我得到
To make them smaller, I tried
为了让它们更小，我试过
axes.errorbar(x, y, yerr=ci, fmt='-o', s=1, color='k')
but no luck.
但没有运气。
