[ferret_users] Re: plot/vs/ov interferes with x-axis numeric labels

[Ryo Furue <furue@xxxxxxxxxx>]

Dear Ferret users,

I'm trying to plot a land mask (with fland) over an open polygon, but the numeric labels of the x axis miss the longitude labels, "E" or "W".

[ . . . ]

fill/noaxis/nolabel . . . missingdata !--- (1) Set up the axes

plot/vs/ov xpoly, ypoly  !--- (2) plot the line

go fland 20, , , , , , axes  !--- (3) plot the land, axes, and gridlines

A friend has found another workaround

! . . . . . . .

ppl xfor (i3,''LONE'')
go fland 20, , , , , , axes

The FLAND script uses SHADE internally and the above code specifies the format of the x-axis numeric labels to be the correct one.

go fland 20, , , , , , axes
