matplotlib:使加号变粗 [英] matplotlib: make plus sign thicker

问题描述

在Matplotlib中，我想画一个粗加号(或一个十字)，但是

In Matplotlib, I would like to draw a thick plus sign (or a cross), but the one provided in the marker set is too thin.

即使我增加了它的大小，它也不会变厚.

Even as I increase its size, it doesn't get any thicker.

对于示例: 绘制红色加号的代码行是:

For example: The lines of code drawing the red plus sign are:

# Draw median marker.
if plot_opts.get('bean_show_median', True):
    ax.plot(pos, np.median(pos_data),
            marker=plot_opts.get('bean_median_marker', '+'),
            color=plot_opts.get('bean_median_color', 'r'))

如果我添加一个额外的参数markersize=20，则标记只会拉伸.它会像以前一样薄.我可以把它厚吗?

If I add an extra parameter markersize=20, the marker will only stretch. It will be as thin as before. Can I make it thick?

推荐答案

您可以使用markeredgewidth(或mew).您需要将其与markersize结合使用，否则会得到粗大但很小的标记.

You can use markeredgewidth (or mew). You'll want to combine it with markersize, otherwise you get thick but tiny markers.

例如:

plt.plot([2,4,6,1,3,5], '+', mew=10, ms=20)
