Anybody know how to set the Data Plot Crowding value from a script?

Ok... 2 1/2 years later, I have the same question: How can I set station plot density in a script?

No one has ever wanted to do this in an automated script station model??!! I don't believe it.

I don't think you can set data point crowding via a script. "plf" is the standard data plot product code, and there does not seem to be a parameter that controls density. The format I use in my scripts is "product,plf,tmf,0,plot", which basically tells the program to plot ("plot") standard data points ("plf") using fahrenheit ("tmf"); I do not know what function (if any) the "0" serves. I tried changing up its value to different numbers, but it made no difference. Data plot crowding always came out the same, which, in turn, is controlled by the Data Plot Crowding slider in the DA control panel. "Product" in the script simply tells the program to use the designated product code ("plf").

It may be possible to use custom surface plot model using the SPCPLOTMODEL command, but, if so, it's beyond my meager scripting ability to explain.

Jim, try this:

I wrote and tested this against the Pro version. I'll need a Standard version user to tell me it if works for the Standard edition. Also, if there's anything else that someone wants scriptable, let me know and I'll see what I can do.


P.S. Thanks Tim and Shannon and thanks for the great software!

Anybody has the script which steveg mentioned for Data Plot Crowding value because the link isn't working

I don't know if this is what was posted on that website, this came from the board.
However, I have played with this and so far have not been able to control plots from a script. Maybe Tim will be able to answer this question?

I didn't know there was a request for this, but unfortunately I don't get into the scripting forums much. The capability has been added and will take effect with V3.10b.

Added DENSITY scripting command. This controls the Data Plot Crowding slider bar. Usage is DENSITY,position where position equals 0, all the way left (sparse) to 100, all the way right (plot all data).

Definitely e-mail me directly for feature requests as the forums are kind of an indirect method of contact.

And a big thanks to Tim for adding this now I don't have to play with the slider for density at alt, then surf and different sized maps!!!!!
And when it is changed that change will stay in place until you change it again, by script or slider!!! Took me a while to figure out where the density,# went in script...for those like me, here it is:

analyze,FILL COLOR=167:000:255 FILS=0 GRTN=-10 FILL COLOR=249:000:249 FILS=0 GRTN=-20 degf TEMP h700
