There are several factors which affect the TEXT plotting.
In the first instance you only show a size of ".7". The
font style and HW/SW flat will default to their previous
setting- thus depending on what you had run in that
directory/gplt session previously would continue to be in effect.
Make sure you set all the items size/style/width/hw-sw
in order to compare.
Also added in 5.9.4:
was the ability to control text size in line for individual parameters,
so you would want to ensure you aren't overriding any text attributes
The text size and line width can also be specified for plotting
numerical data such as temperature and dewpoint. These follow
the parameter name, or condition, delimited by colons. For
example, TMPF:2.5:3 , would cause temperatures to be plotted
with a text size of 2.5 and a line width of 3. Text sizes that
are positive cause the data to be plotted at the location they
would appear if they were being plotted with the largest
specified text size (ie. farther from the center of the station
model than they would normally appear). Text sizes that are
negative cause the offsets from the center of the station model
to be computed based on the specified text size. NOTE: A large
range of negative text sizes may result in some degree of
overplotting. When using hardware fonts, text sizes may be named
sizes. For example, tiny, SMALL, m, -m, -LARGE, etc, are all
valid specifications. If no text size is provided for a particular
data type, that data will be plotted with the default text size
specified in the TEXT parameter.
If you are still having trouble with sizes, please send me the script
so I can run with the same TEXT, SFPARM, DEVICE settings
that you used to produce the plots.
