命令行中画图

利用 item2客户端， ssh远程到服务器中，竟然能画图

• 例子1

imgcat fig.jpg

• 例子2

export GNUTERM=png
gnuplot -e "plot [-10:10] sin(x)" | imgcat

• 例子3

python -c  'from pylab import *; x= linspace(-10,10,100); plot(x,sin(x)); show()'

• 例子4

imgcat <- function(plot_command){
  fn <- tempfile(pattern = "file", tmpdir = tempdir(), fileext = ".png")
  png(fn)
  eval(quote(plot_command))
  dev.off()
  system2("imgcat", fn)
}


x = (-100:100)/10
imgcat(plot( x, sin(x ), type='l' ))


library(ggplot2)
p <- ggplot(iris, aes(Sepal.Length, Sepal.Width, color = Species))
imgcat(print(p))
