更改图例符号的大小 [英] Change size of legend symbol

问题描述

如何更改图例中符号的大小？现在他们看起来像这样：

I希望它们与标题的尺寸大致相同。看过文档后，我想改变symbolHeight，symbolRadius和symbolWidth会做的，但事实并非如此。事实上，就我所知，这些参数根本不会改变。 如果您正在使用线条系列，则需要将其图例符号更改为列系列图例符号。 然后您可以使用 symbolHeight ， symbolWidth 和 symbolRadius 属性。

API参考：

How do I change the size of the symbols in the legend? Right now they look like this:

I would like them to be squares approximately the same size as the titles. After looking at the docs, I thought changing symbolHeight, symbolRadius and symbolWidth would do the trick, but it doesn't. In fact these parameters don't change anything at all, as far as I can see.

解决方案

If you are using line series, you need change its legend symbol to column series legend symbol. Then you can use symbolHeight, symbolWidth and symbolRadius properties.
