Re: [ferret_users] accuracy of axis in ferret

I've used big topographic data sets from ascii values.  When the axis is very long, ferret gets the spacing wrong due to rounding error.  You can get around this for evenly spaced axes by using the npoints parameter.  Try something like this

define axis/x=1:100000/npoints=100000 my_axis

to get an even axis 100,000 points long.
