I am using PGFPlot with external table data. However, some values are missing for some plots. This causes data in column 2 does not exists error. Is there a way to solve this. The value does not exists and all data for x, ind3 should be considered as {(1,7)(3,15)}. Is there a way to overcome this problem?
The following is the data file I tried to create:
x ind2 ind3
1 5 7
2 9
3 11 15
And plot commands
\addplot[color=blue, mark=x] table[x=x, y=ind2] {performance.data};
\addplot[color=red, mark=+] table[x=x, y=ind3] {performance.data};
