RAH /SIZE
|
|
Normally the RAH command scales its plots as large as possible to minimize
whitespace. But that means a series of RAHs runs would be plotted
at different scales when their maximum righting arms differ significantly...
making them difficult to compare at a glance.
This can be fixed using the RAH /SIZE:max parameter by specifying the same maximum (and optionally minimum) righting arm scale values. An even easier way to handle this is to specify /SIZE:* on subsequent RAH runs so the scale sizes from the first RAH plot are reused. For example: |
|
READ LINER14 DR 12 | SO WE LCG | VCG 8 CRT FLOODER 75 14 20 REPORT RA RA /GRAPH:ONLY /STOP:FLD /SIZE:* RA /GRAPH:ONLY /STOP:FLD REPORT CLOSE /PREV |
|
In this example, the /GRAPH:ONLY parameter omits redundant table output (see COW194) and the /STOP:FLD parameter stops subsequent RAH runs when the downflooding point immerses, preventing plots from reaching their normal maximum righting arm and heel values: |
|
| But when /SIZE:* is present, the stopped plot remains nicely scaled the same as the preceding original: |
