#343 transparent lines


gnuplot supports transparency in some cases, but not for simple lines. It would be helpful to be able to do something like 'plot x lc rgba "#AABBCC00"' to plot transparent lines on top of each other.

    This feature is already present in the current development version (4.7).

    gnuplot> help rgbcolor
    "#AARRGGBB" represents an RGB color with an alpha channel (transparency)
    value in the high bits. An alpha value of 0 represents a fully opaque color;
    i.e., "#00RRGGBB" is the same as "#RRGGBB". An alpha value of 255 (FF)
    represents full transparency. `Note`: This convention for the alpha channel
    is backwards from that used by the "with rgbalpha" image plot mode in earlier
    versions of gnuplot.
