Hi,
First of all, thanks to all for the work on org-mode and org-plot.
A question about org-plot...
Question 1:
When I include an index column in the first column of the table, I am
getting evenly spaced data points, with the xtic labels being coming from
the 'ind:' column (2, in the first data set here).
The behavior I expected was to use the second column (Frequency) as the
independent variable, and to get a plot with 3 groups of 3 points, near
frequencies of 1, 10, and 20. as I get with the 'Data Set B' group.
Is this expected and correct?
I know that this will also include the first column in the plot, which leads
to my next question.
Question 2:
When I try to use the deps option, I either get an error or an undesired
result. For example, if I include a "deps:3,4", I get a "Wrong type
argument" error. If I enclose the 3,4 in single quotes (eg. deps:'3,4'), I
get only the third column plotted, and not both third and fourth as I
expected. What am I doing wrong?
A comment - enclosing the argument for deps in single quotes, if that is the
intention, seems inconsistent with the arguments for other options of that
type (ind, for example).
Question 3:
Is there a way to produce 2 different plots from the same table data?
Thanks again for the help.
Jerry

Hi Jerry,
Not exactly expected, but I believe it is the correct behavior for now.
Notice that you are missing an hline in your table after the headers.
Without an obvious division between the headers, and the table data
org-plot can not tell that the data is numeric, and should be
interpreted as such, so it applies the values of the index column as
xlabels to evenly spaced points (as if they were strings). Try the
following table, and you should get a result more inline with
expectations.
#+PLOT: ind:2 with:points
| Index | Frequency | Amplitude | Phase | Delta | Peak |
|-------+-----------+-----------+-------+-------+------|
| 1 | 0.9 | 9 | 6 | 5 | 198 |
| 2 | 1.0 | 10 | 9 | 7 | 212 |

Sorry, the documentation is wrong and it specifies that the dependent
columns should be specified as a comma separated list, when in actuality
they should be specified as a standard lisp list "inside parenthesis
separated by spaces". Thanks for catching this, I will submit a patch
to the documentation.

Currently no there is not. In the current setup all of the plot lines
adjacent to a table are collected and used to generate a single plot for
the table. I does seem like a good idea to allow multiple plots from a
single table. Two ideas that come to mind are...
1) keep all of the plot lines adjacent with the table, but number them
into any number of different plots. For example the following would
specify plots 1 and 2 for a table
#+PLOT1: title:"the first plot"
#+PLOT1: ind:1 with:points
#+PLOT2: title:"the second plot on the same table"
#+PLOT2: ind:2 deps:(3 4) with:lines
| Frequency | Amplitude | Phase | Delta | Peak |
|-----------+-----------+-------+-------+------|
| 0.9 | 9 | 6 | 5 | 198 |
| 1.0 | 10 | 9 | 7 | 212 |
| 1.1 | 11 | 8 | 3 | 144 |
| 9.9 | 19 | 12 | 9 | 235 |
| 10.0 | 18 | 7 | 12 | 222 |
| 10.1 | 22 | 14 | 4 | 187 |
| 19.9 | 14 | 11 | 6 | 220 |
| 20.0 | 20 | 15 | 14 | 213 |
| 20.1 | 18 | 16 | 11 | 201 |
2) the only other mechanism which occurs to me is to somehow label the
table with a unique ID, and then allow the plot lines to be located
anywhere in the org-mode file and include the table ID as a new
argument to the PLOT lines. This approach seems more flexible if
more complicated.
Thanks for the bug reports and ideas -- Eric

Thanks, Eric!
It's a great tool... I like how it, within org, makes it easy to keep the
data organized an yet easily accessible.
Another quick org-plot question...
I found that to turn on the grid, I use:
#+PLOT: set:grid
So, to set an axis label, I tried
#+PLOT: set:xlabel("Frequency")
and
#+PLOT: set:xlabel "Frequency"
and a few other things, but didn't hit on the right combination. What's the
correct syntax?

This feature (multiple plots from a single table) would be a very nice
addition, with either approach.

try
#+PLOT: set:"xlabel 'Frequency'"
You need the double " quotes for any argument that contains spaces, and
gnuplot requires quotes (in this case using single ' quotes) around the
argument to xlabel.
I agree this isn't obvious, if you have a suggestion for improving the
syntax please let me know.

I agree, if I find time I will look at implementing it.

I haven't looked into this matter, so this comment might not be
relevant, but I do have a suggestion that I had earlier written for
the *general* problem of choosing a syntax for new functionality when
you don't have obvious models to follow.
Some of the desiderata for a syntax include: consistent, easy to
parse, hard to corrupt, simple to quote, simple to escape (especially
with things like regexps that are already complicated), supports being
confident that exporting will not exhibit unexpected behavior, easier
for the user to remember without reference materials, flexible,
extensible, supports macros, nestable, pretty-printable, a published
reference standard, and print-readable (serializing). If your syntax
has those, then you're doing well.
If you don't have a model to follow (such as org or gnuplot), then
Lisp (el because this is el or cl because it's a standard that is
similar to el and meticulously speced) has usually had a lot of
thought put into its syntax. You might get a joke or two, but we know
better. :)
Again, perhaps not relevant, but maybe food for thought for future
questions about syntax.
