[ferret_users] Error on go error_bars



Dear Ferreters,

I would like to plot a variable and it's error as a filled polygon. 

Based on "error_bars_demo.jnl" I'm running the following commands:

use coads_climatology
let mean = airt[x=60W:10E, y=0, l=@ave]
let stdv = airt[x=60W:10E, y=0, l=@var]^0.5
plot/vlimits=23:30 mean
go plot_swath poly/over/pal=gray/nolab mean-stdv, mean+stdv

When I call the plot_swath script, Ferret returns the following error message:

 **ERROR: error: data is not a line

The same happens when I try "go error_bars".

"error_bars_demo.jnl" plots ok, and I can't see what I'm doing wrong in comparison to this demo script.

Could someone please help me?
