controling colour station data according to defined range.

[Jennifer Faber]

Hi Jennifer (and rest)

Thanks you for your fast reply! I never knew about this option. But unfortunately I dont wanna plot the parameters as dots that represents the station location. I want to plot parameters like temperature, rainfall, wind direction and speed measured by the station as values (not as dots) and control the colours of these parameters. If I "set gxout value" then I can plot the values but I cannot color the colors according to their value. Any new suggestions?? (I dont know if it is allowed, but I added a file as an example what I mean) 

Greetings,
Jennifer Faber

  Use 'set gxout stnmark' and you'll get a colorized dot where the station location is. Then 'set clevs' and 'set ccols' and 'set digsiz' will allow you to control the colors and levels and size of the dots.

    Dear all,

    Problem: I am trying to plot MOS data in GrADS. This data is station data and we already created a numerical model and STNmap utility to read and draw into a grid. What I want to do is colour the parameters according to their values. In essence the same as what you can do for the contours (shaded or not) but now for gridvalues or stationdata.

    With Tmax as example we managed: to plot the Tmax of all stations (of MOS file) with gxout shaded using oacreas. Here we can manipulate the colours and the range.

    Now: We want to plot the value Tmax as value (not contour) and then colour the value according to a range. I cannot use clevs or ccols because that is only for contours. And I cannot use fgvals neither because then it will colour the entire grid and not the grid value. All I can do with the value is change digit, change size and colour them, BUT all in the SAME colours.

    I didnt include a script, because no script I tried, solved this problem.
    I hope you can help me. Thanks!
