在 matplotlib 图形上启用白框/禁用透明框 [英] Enable white frames on matplotlib figure/ Disable transparent frames

问题描述

我正在以深色主题运行 ipython notebook.当我在其上构建图表时，图表是白色的，但框架是透明的(因此是黑色的)，隐藏了同样黑色的刻度线.有没有办法让框架不透明/白色?

I'm running ipython notebook on a dark theme. When I build a chart on this, the chart is white, but the frame is transparent (hence dark), hiding the ticks which are also dark. Is there a way to make the frame not transparent/ white?

由于黑色背景，蜱虫几乎看不见.

The ticks are barely visible due to black background.

我该如何解决这个问题?谢谢！

How do I solve this? Thanks!

这不是关于改变轴、刻度/标签的颜色，我想添加一个白色背景框架，而不是改变刻度的颜色 - 如果我只是改变颜色打勾，因为数字是白色的

This is not about changing the colors of axis, ticks/labels, I'm thinking of adding a white background frame, not changing the colors of ticks - it'll be ugly if I just change the color of the ticks because the figure is white

推荐答案

jupyter 中显示的带有 %matplotlib inline 后端(通常是默认设置)的图形是通过通过 savefig 到一个 png，然后显示.savefig 有一个参数 facecolor 来设置图形背景的颜色.这可以设置为白色，例如fig.savefig("name.png", facecolor="w").

The figure shown in jupyter with the %matplotlib inline backend (which is often the default) is created via saving it through savefig to a png that is then displayed. savefig has an argument facecolor which sets the color of the figure background. This can be set to white, e.g. fig.savefig("name.png", facecolor="w").

保存选项可以在 jupyter 配置中进行调整.要实现白色背景，可以设置

The options for saving can be adapted in the jupyter configuration. To achieve a white background one can set

%config InlineBackend.print_figure_kwargs={'facecolor' : "w"}

在显示绘图之前的单元格中.

in a cell prior to showing the plot.

如果要用于每个笔记本，也可以将其添加到ipython 配置文件

If that is to be used for every notebook, it can also be added to the ipython configuration file

c = get_config()
c.InlineBackend.print_figure_kwargs={'facecolor' : "w"}
