Re: [opendx-users] Simple Graphing?
Can I for example plot a line from a CSV File like this
0,100
In case you had spaces instead of commas, the following .general file (where
the number of points and the name of the file are replaced by fitting values)
suffices:
points = 10
file = input.dat
format = ascii
interleaving = field
field = x, y
structure = 1-vector, scalar
type = float, float
dependency = positions, positions
end
You simply need to connect [Import] - [Plot] - [Image], supplying [Import]
with the name of the input file and general as the format. In [Plot], you
can use { lin, log } as type input if you want the Y axis to be
logarithmic. This and more info about [Plot] can be found on
http://opendx.npaci.edu/docs/html/pages/refgu104.htm#HDRPLOT
.general files can also be generated by using the Data Prompter, which asks
you for your file's properties:

Re: [opendx-users] Simple Graphing?
There are lots of ways to do it in DX. Not quite sure what you mean by smooth, but take a look at the Plot examples. David I have been playing around with OpenDX for a few hours and it is a cool program. One thing that I do a lot is plot lines/smoothed lines from data in CSV files. Can OpenDX do this or do I need to use another package for it? Can I for example plot a line from a CSV File like this 0,100 1,49 2,24 3,12 4,6 5,3 6,1 7,0 And get graph with the points plotted and lines connecting them? What about smoothed lines? Whats the basic VP (Visual Program) to graph such a line from a file? I know this may be an extremely simple task, perhaps even bellow OpenDX, but its something I would like the be able to do so that I can incorporate line graphs into OpenDX visualizations.

Re: [opendx-users] Simple Graphing?
Please excuse my stupidity,
What is a .general file? I know how to edit and create .net files
using the VPE, but I am unfamiliar with these .general files. What are
they? How do I use them?
Thank you for your time,

As you wrote that you played with DX, I presume that you have tried some
examples. In those, the Import module usually has a filename given as input to
indicate where the data to be visualized resides. If your data is not in a
format that DX understands 'naturally', you need to create a second file that
refers to your actual data file and describes it.
.general stands for General Array Format; the DX manual simply refers to
such files as header files because they only describe data, but do not
contain any. When you use the Data Prompter (option General Array Format)
for importing data, it will ask for your data file's structure and create such
a header file. Alternatively, you can write one yourself -- e.g. using
cutpaste from my former email. For own attempts, the following might help:
http://opendx.npaci.edu/docs/html/pages/qikgu028.htm
As I mentioned, you can supply the Import module with the name of such an
input file, but have to change the format input to general to tell the
module about the given file's non-standard format. To sum it up: You will have
a DX net ('visual program') whose Import module refers to a .general file,
which in turn refers to your data table (.csv with commas replaced by spaces).
