The data is in an xy grid starting from 74.16 degrees east and 90 south
with a resolution of 0.08333 degrees. Thus to set latitude and
longitude I have to calculate the xy range from this origin and cannot
define the range as</span></div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:times new roman, new york, times, serif;background-color:transparent;font-style:normal;"><span class="yiv6653693396tab"> </span><span class="yiv6653693396tab"> set lon lon1

The second problem that arises is that I cannot plot across the
longitude origin, if I try to plot from say 70E to 80E it only plots
from 74.16 to 80 and if I plot from 430 to 480 it will only plot data
from 430 to 474.16.<br></span></div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:times new roman, new york, times, serif;background-color:transparent;font-style:normal;"><span class="yiv6653693396tab"> Does anyone have an elegant solution or helpful hints to these
