Question

在朱莉娅0.5你可以写：

using DataFrames, Plots, StatPlots
df = DataFrame(
    fruit = ["orange","orange","orange","orange","apple","apple","apple","apple"],
    year = [2010,2011,2012,2013,2010,2011,2012,2013],
    production = [120,150,170,160,100,130,165,158],
    consumption = [70,90,100,95, 80,95,110,120]
)
plotlyjs()
mycolours = [:green :orange]
legend1 = sort(unique(df[:fruit]))
legend2 = legend1'
fruits_plot = plot(df, :year, :production, group=:fruit, linestyle = :solid, linewidth=3, label = ("Production of " * legend2), color=mycolours)

其中legend1是2-element DataArrays.DataArray{String,1}而legend2是1×2 DataArrays.DataArray{String,2}。

现在，在朱莉娅0.6 legend2 = legend1'不再工作了。您可以改为使用legend2 = reshape(legend1, (1, :))，但这会产生一个相当模糊的1×2 Base.ReshapedArray{String,2,DataArrays.DataArray{String,1},Tuple{}}，然后在plot()调用中不会被接受。

那么，从2-element DataArrays.DataArray{String,1} 1×2 DataArrays.DataArray{String,2}生成julia 0.6的任何方式？

再次，在SO上发帖有助于..; - ）

我终于得到了我可以获得预期字符串连接的情节：

fruits_plot = plot(df, :year, :production, group=:fruit, linestyle = :solid, linewidth=3, label= reshape("Production of " * sort(unique(df[:fruit])),(1,:)), color=mycolours)

如何在Julia 0.6中转置字符串向量（为了绘制多个图例）？
