Re: How to plot a map-plotting figure with station data?

Yes,  I'll show how to do this with the polymark demo; the LABEL command
makes a label at any point on the plot.  We can use the variables lat and lon
to label the value of the some of the points. 

yes? use polydata  ! this is in the Ferret distribution.
yes? go basemap x=130:250 Y=20:65 20
yes? go polymark poly/over/key/title="SST along track" lon lat sst star
yes? show data

! Label every fifth point. The marks around lon, lat and sst are grave accents,
! to force evaluation of the variables at the particular value of I at each repeat.
! The value of SST is put into a string. 

yes? repeat/i=1:37:5  (label `lon`, `lat`, 0, 0, 0.1, "`sst`")

You might want to move the labels slightly away from the points, by using,
say,   `lat+1`

And, we can clean up the labels by limiting their precision:

yes? repeat/i=1:37:5  (def sym sstlab = "`sst,prec=2`"; label `lon`,`lat+1`,0,0,0.1,($sstlab) )

Hi, Ansely.

I could plot the figure that I want now.

Thanks for your help!

But I have another question, that is,

could I write the station data value around each point?

thanks.

Hi,
I'm not sure what you are asking.  You can draw a map using a
topographic data set and overlay the locations of your stations
using the POLYGON command.  Here is a demonstration which
does that.  The example shows a ship track, but it shows how to
plot a set of   longitude, latitude locations.

 

Hi all,

I want to plot  map-plotting figure with my station data using ferret v5.6.

Does ferret has this function?

Anybody knows how to do this work?

Thanks for your help!
