Nick,
How about this?? Just fiddled around a little and wonder what you think. There might be a better way, but essentially, I've done the following:
- Left y-axis = distance
- Right y-axis = time
- I couldn't get the xtic(1) option to work, so I replaced things with what I've found to work x:y:xticlabels(col#)
- Beefed up the points to make them a little easier to see
- Used your data to "calibrate" your speed
--- The left y-axis is from 9-21min
--- The right y-axis is from 1.5min - 3.5min
--- This means the axes are 'calibrated' to 10mph
What does the "calibration" do? It means that at a quick glance you can see your speed based on a target rate you set:
- if speed/distance are on top of each other, you're right at your target
- if speed (green) is higher than distance (red), you were faster than your target
- if speed (green) is lower than distance (red), you were slower than your target
Resetting your target is as easy as changing (in the code below):
- Time: yrange [y1:y2]
- Distance: y2range [y3:y4]
All you have to do is make sure that y3/y1 = y4/y2 = target speed
Also, remove the references to L/R and Red/Green if you'd like from the labels. I just tried to make the labels as easy as possible to follow so that no matter where you looked for a reference you would be forced to see what color/axis matched what value.
I attached a sample graph. Sorry if I overstepped my bounds -- I realize it's your workout tracker. Take what you like and ditch the rest. I wanted to know how to do two different y axes anyway so it helped me learn. Code is here:
------------------- gnuplot code -----------------------

set style data points
plot data u 2:3:xticlabels(1) axis x1y1 lw 3 title 'Time (L axis)', \
data u 2:4 axis x2y2 lw 3 title 'Distance (R axis)'
#+end_src
------------------- end gnuplot code ---------------------
Best regards,
John

John,
I am reworking the gnuplot script, it is not done at this point, but this is what I currently have:
#+begin_src gnuplot :var data=sessions :file org-running.png :exports both
set title "Running Stats"
set xtics nomirror rotate by -45
set key noenhanced
set style data linespoints
plot "$data" using 2:xtic(1) title columnheader(1), \
for [i=2:3] '' using i title columnheader(i)

Nick,
This got me curious to see the output. I tried to generate it on my computer and get this in the *gnuplot* buffer after running the code:
-----
gnuplot> plot data using 1:2:3 notitle
^
warning: Skipping data file with no valid points
^
x range is invalid
-----
This is working for you, though?
#+tblname: sessions

| 09/01/2010 | 14:00 | 2.4 |
#+begin_src gnuplot :var data=sessions :file org-running.png :exports both
set title "Running Stats"
set auto x
set style data histogram
set style fill solid border -1
set boxwidth .9
set xlabel "Date"
set ylabel "Time"
plot data using 1:2:3 notitle
#+end_src

Erik,
That was the issue, the :file reference needed to be on the line above. Thanks.

Hi John,
I would actually like to plot different lines per distance, each
that correlate to a date and elapsed-time (x and y axis respectively).
I get an error with the :file notation, though I read that in a sample
babel gnuplot example for generating graphs of commit history on the
org-mode git repository. I tried to reference the variable data without
the quotes and $ sign without any success. I will continue to fiddle
with it, I am new to gnuplot.
multiple lines. Is that how you actually have it in your
org file?
#+begin_src gnuplot :var data=sessions
:file org-running.png :exports both
set title "Running Stats"

set style data histogram
set style fill solid border -1
set boxwidth .9
set xlabel "Date"
set ylabel "Time"
plot "$data" using 1:2:3 notitle
#+end_src
