From a data file I am using two columns to plot boxes with 50% saturation: plot "data" using 1:4 axis x1y2 title '...' with boxes fs solid 0.5 I'd be interested to know whether it's possible to change that constant 0.5 to become a parameter also controlled by the data file. In the "data" file I have a column that contains percentages in the range from 0% to 100% that should be mapped to a range of something like "solid 0.0" to "solid 1.0". Would that be possible to achieve, and if so, how? Thanks!

I'd also appreciate a negative confirmation, that what I intend is not possible to achieve with gnuplot.

It is not possible to make the "fs solid" parameter variable. However in the development version (4.7) it is possible to make the fill color itself a variable and encode the alpha channel value in the upper bits of the color. That would achieve the same result.
