如何绘制a＆＃x27;比例图形＆＃x27;在朱莉娅？

Question

这是我正在寻找的示例：

我查看了文档中的所有示例，但找不到类似的图表。任何帮助将不胜感激。

Answer 1

这是一种方法：

using Plots

@userplot StackedArea

# a simple "recipe" for Plots.jl to get stacked area plots
# usage: stackedarea(xvector, datamatrix, plotsoptions)
@recipe function f(pc::StackedArea)
    x, y = pc.args
    n = length(x)
    y = cumsum(y, dims=2)
    seriestype := :shape

    # create a filled polygon for each item
    for c=1:size(y,2)
        sx = vcat(x, reverse(x))
        sy = vcat(y[:,c], c==1 ? zeros(n) : reverse(y[:,c-1]))
        @series (sx, sy)
    end
end

a = [1,1,1,1.5,2,3]
b = [0.5,0.6,0.4,0.3,0.3,0.2]
c = [2,1.8,2.2,3.3,2.5,1.8]
sNames = ["a","b","c"]

Answer 2

以下@sanidhya-singh的链接还提供了一个内置解决方案：

julia> areaplot(1:3, [1 2 3; 7 8 9; 4 5 6], seriescolor = [:red :green :blue], fillalpha = [0.2 0.3 0.4])

它提供了

也许值得添加到文档中！
