Julia: ver.1.0.2
GR: ver0.6, ver1.0

GRでtitleや軸ラベルの設定

hoge = [1,2,3]; foo = [1.5,2.5,3.5]
data = [hoge, foo]
labels = ["hoge", "foo"]
using Plots
Plots.gr()
plot(data, 
     xaxis = "x axis",
     yaxis = "y axis",
     label = labels,
     title = "aa")

`GR: ver0.6 & ver1.0`の場合

title等に日本語やギリシャ文字を使うと，
BoundsErrorを吐く (なんでBoundsError ??)

hoge = [1,2,3]; foo = [1.5,2.5,3.5]
data = [hoge, foo]
labels = ["hoge", "foo"]
using Plots
Plots.gr()
plot(data, 
     xaxis = "x axis",
     yaxis = "y axis",
     label = labels,
     title = "あ")
