Bernard,
I have been sick and am trying to work from home and I keep getting cut
off, so it's counter-productive to try to write an example for you, but ...
To map CONPACK output to a linear/log plot, it should be sufficient to
1. CALL CPSETI ('SET',0) to tell CONPACK not to do its own SET call.
2. CALL CPSETR ('XC1',X1) to tell CONPACK what user-system X value is
associated with a first subscript of 1.
3. CALL CPSETR ('XCM',XM) to tell CONPACK what user-system X value is
associated with a first subscript of maximum value.
4. CALL CPSETR ('YC1',Y1) to tell CONPACK what user-system Y value is
associated with a second subscript of 1.
5. CALL CPSETR ('YCN',YN) to tell CONPACK what user-system Y value is
associated with a second subscript of maximum value.
6. CALL SET to tell NCAR Graphics how user-system values are to be mapped
to the plotter frame. Arguments 1-4 tell it what portion of the frame
to use, arguments 5-8 are X1, XM, Y1, and YN, and argument 9 is a 2.
7. Do the calls to CPRECT, ARINAM, CPCLAM, etc., that you have now.
8. Do whatever calls you like to label the axes. I haven't looked at
your GRIDAL calls in detail, but they seemed all right ...
I should be back in my office tomorrow and will try to put together an
example for you then, but the above steps are the key ones, I think.
