[opendx-users] How to generate/pass a time vector?

Hi! I need to add an additional output to my import module that reflects the time of the data, ideally this should be a vector as I have physical time, model time and iterations. What kind of object is appropriate for such data and how can I generate it? (I assume just allocatin a DXVec and

Re: [opendx-users] World Data Bank file question

Most map file formats like WDB, MIF, etc. basically are designed for pen plotters. That is, connecting the dots when the pen is down, lift the pen up, move it somewhere else, put the pen down and connect some more dots. In ASCII they look like this: n lat1,lon1 lat2,lon2 . . . latn,lonn m

Re: [opendx-users] How to generate/pass a time vector?

Thanx! Thats it what I was searching for. Richard. No problem. I just want you to realize how powerful the UI based language is, so you don't waste time rewriting code that's already written. Naturally, there are occasions where a custom module is required. I've written about 5 in the last 11

Re: [opendx-users] header for Fortran unformatted output

Does it mean that each run will output instead of one two ~300 MB files? It would be so convenient to write just a header instead of duplicate the output for Data Explorer. Thanks anyway. Ted Richard Guenther wrote: On Sat, 10 Feb 2001, Ted Sariyski wrote: Hi, I am trying to write a

[opendx-users] World Map coordinate system

I'm almost embarrassed to ask, since I'm obviously missing something (probably simple), but how do I shift the coordinate system of the cylindrical equidistant (rectangular) global map so that it goes not from -180 to -180 degrees longitude but instead ranges 0-360 ? There are inputs into

[opendx-users] dumb question

Hi Is there a quick and obvious way to use colormap to plot my 3D data on a log scale. Or would I have to log the data first ? thanks trudy ~ Knowledge divides the world ~ ~ Wisdom makes it whole ~ -anonymous

[opendx-users] Strange Map behaviour

Hi, Either I miss something or I encountered strange behavior of Map module :-(. The problem is as follows: We have scalar function of two variables f = f(x,y); Let assume that f(x,y)= x^2 + y^2 and x in [-0.5,1.0], y in [-0.5, 1.5] Draw the profile of function 'f' along a line parallel

Re: [opendx-users] World Map coordinate system

You can use Transform from the Rendering category with positions of [0 -180 0]. Then to actually apply them if needed (convert the actual positions), you can run the output through Inquire with option apply transform. David I'm almost embarrassed to ask, since I'm obviously missing

Re: [opendx-users] World Map coordinate system

The file, WDBI.dx, used by that macro has the coordinates as provided in the original World Data Bank I file. The coordinates are raw lat-lon, cylindrical equidistant, with lon as degrees east (-180 to 180). A simple transformation such as Mark/Compute/Unmark or Transform will only partially
