我正在制作一个 Pluto 笔记本，在其中使用多个绘图库创建相同的简单绘图。由于绘图库可能会定义具有相同名称的函数，因此我的工作方式如下：

using AlgebraOfGraphics, RDatasets, CairoMakie
const AoG = AlgebraOfGraphics

iris = dataset("datasets", "iris")

iris_frequency = AoG.data(iris) *
    AoG.mapping(:PetalLength, :PetalWidth) *
    AoG.mapping(color = :Species) 
AoG.draw(iris_frequency)

在此处输入图像描述

但是，当我这样做时，我using gadfly在调用时遇到错误AlgebraOfGraphics.draw()，我不清楚为什么。

using Gadfly
AoG.draw(iris_frequency)

MethodError：没有方法匹配大小（::Compose.Property{Compose.FillPrimitive}）

最接近的候选人是：

/opt/julia/usr/share/julia/stdlib/v1.6/LinearAlgebra/src/qr.jl:524

大小（！Matched::Union{LinearAlgebra.QR，LinearAlgebra.QRCompactWY，LinearAlgebra.QRPivoted}，！Matched::Integer）在 /opt/julia/usr/share/julia/stdlib/v1.6/LinearAlgebra/src/qr .jl:523

/opt/julia/usr/share/julia/stdlib/v1.6/LinearAlgebra/src/cholesky.jl:442 的大小（！Matched::Union{LinearAlgebra.Cholesky, LinearAlgebra.CholeskyPivoted}）

注释掉# using Gadfly并不能解决错误，但这可能是由冥王星引起的。

Pluto 的实时文档识别AoG.draw()为AlgebraOfGraphics函数，并typeof(iris_frequency)返回AlgebraOfGraphics.Layer（如您所愿。）

有人知道Gadfly如何导致此错误，以及我如何解决它（除了在不同的笔记本中创建绘图。）
