Probably the simplest way to do this is to draw over the x axis with a colored line, using the PLOT/VS command. Here is how to do this on a single plot: Draw the plot. When it is drawn, Ferret defines symbols xaxis_min, xaxis_max, yaxis_min, yaxis_max.
yes? plot my_var ! draw your plot. This can use any plot, shade, fill commands
yes? plot/over/vs/line/color=red/nokey {($xaxis_min), ($xaxis_max)}, {($yaxis_min), ($yaxis_min) }
The { } syntax creates a variable out of a list of values; in this case the x and y coordinates of the start and end of the x axis.
I think you should be able to do something similar with your multiple plots, using the same method.

Dear Ferret users:
I wonder if ferret can have different colors of each axis line when I use multiple x-axis.
In other words, how can I have, say, a red x-axis line?
