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 | | 3 | 1.1 | 11 | 8 | 3 | 144 | | 4 | 9.9 | 19 | 12 | 9 | 235 | | 5 | 10.0 | 18 | 7 | 12 | 222 | | 6 | 10.1 | 22 | 14 | 4 | 187 | | 7 | 19.9 | 14 | 11 | 6 | 220 | | 8 | 20.0 | 20 | 15 | 14 | 213 | | 9 | 20.1 | 18 | 16 | 11 | 201 | > > 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.

Thanks for catching this, I will submit a patch to the documentation. #+PLOT: ind:1 deps:(3 4) | 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 | > > Question 3: > Is there a way to produce 2 different plots from the same table data? > 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.
