I have a .csv with 2-dimensional data. Now I am trying to plot it in different index ranging from -n:1:n (this index is y-axis).
\documentclass[border=10pt]{standalone} \usepackage{pgfplots} \pgfplotsset{width=7cm,compat=1.8} \usepackage{pgfplotstable} \begin{document} \begin{tikzpicture} \pgfplotstableread{ T3,v11 0,0.66582 0.000125,0.66582 0.00025,0.66582 0.000375,0.66582 0.0005,0.66582 0.000625,0.66582 0.00075,0.66582 0.000875,0.66582 0.001,0.66582 0.001125,0.66582 }\dummydata \begin{axis}[ domain=-4:4, samples y=0, ytick={1,...,4}, ] { \addplot3 table [x =T3, y expr=1, z=v11, col sep = comma] {\dummydata}; } \end{axis} \end{tikzpicture} \end{document} This throws errors like:
! Package pgfplots Error: The requested list entry with index 1 of \dummydata i s too large; this list has not enough elements..

However, instead of using a .csv format, if I stick with a table format (that is removing a comma between the data and also col sep = comma in the plot, then I get what I desired. However, the data I have is in .csv format (pretty big). So, instead of creating a huge data-set for y-axis, how can I achieve it with the above-mentioned script.
The one that works without a .csv format (and without creating a huge data-set for a different axis per-se):
\documentclass[border=10pt]{standalone} \usepackage{pgfplots} \pgfplotsset{width=7cm,compat=1.8} \usepackage{pgfplotstable} \begin{document} \begin{tikzpicture} \pgfplotstableread{ T3 v11 0 0.66582 0.000125 0.66582 0.00025 0.66582 0.000375 0.66582 0.0005 0.66582 0.000625 0.66582 0.00075 0.66582 0.000875 0.66582 0.001 0.66582 0.001125 0.66582 }\dummydata \begin{axis}[ domain=-4:4, samples y=0, ytick={1,...,4}, ] { \addplot3 table [x =T3, y expr=1, z=v11] {\dummydata}; } \end{axis} \end{tikzpicture} \end{document} which would give me the desired output:
PS: This is just an example, in reality I use the external file to import my data for plotting purposes.
