使用 R 中的 2+ 个图例来 plotly/plot.ly [英] Using 2+ legends from R to plotly / plot.ly

问题描述

我正在使用 R 的 ggplot 创建一个静态图并将其传递给 plot.ly 以创建一个交互式图.我的目标是将分类变量投影到颜色，将数值变量投影到大小.使用 R 的 [iris] 数据完美运行 - 就像这样:

I am using R's ggplot to create a static plot and pass that on to plot.ly to create an interactive plot. My aim to project a categorical variable to the color and a numeric variable to size. With R's [iris] data that works perfect - Like that:

testplot <- ggplot(iris, aes(Sepal.Length, Sepal.Width, color=Species, size=Petal.Length)) + geom_point()
py$ggplotly(testplot)

现在，我有自己的数据集，a，...

Now, I have my own dataset, a, ...

> a
       Country OR_Edu OR_Illn total num
         Peru   1.75    1.67 25367  10

当我只使用国家作为分类变量时，它也可以工作......

When I use only the country as categorical variable, it works, too...

testplot <- ggplot(a, aes(OR_Edu, OR_Illn, color=Country)) + geom_point()
py$ggplotly(testplot)

但是当我尝试将总计"映射到标记的大小时

but when I try to map 'total' to the size of the marker

testplot <- ggplot(a, aes(OR_Edu, OR_Illn, color=Country, size=total)) + geom_point()
py$ggplotly(testplot)

我收到此错误，尽管总计"显然是一个数值.

I get this error, despite 'total' obviously being a numeric value.

L$marker$size * marker.size.mult 中的错误:二元运算符的非数字参数

Error in L$marker$size * marker.size.mult : non-numeric argument to binary operator

有什么问题?有什么想法吗?

What is the problem? Any ideas?

还有一件事(也许我需要在一个单独的问题中问这个问题):如何自定义悬停时出现的小弹出框?

And onther thing (maybe I need to ask that in a separate question): How can I customise the little pop-up box that appears on hover?

非常感谢！
