Gnuplot, yerrorbar, text as x axis -

-

i have following data:

t4.8k   1.84    1.86    1.83 t5.8k   1.82    1.84    1.8 t7.10k  1.79    1.8     1.77  t8.8k   1.8     1.84    1.76

i need plot in gnu plot using yerror bars.
column1 - dataset name. xaxis scale. column2 - y-mean column3 - y-max column4 - y-min

here plotting code use:

plot "chameleonconfidence.dat" using xtic(1):2:4:3  title "ratio of time taken" yerrorbars

but gives me following error

warning: empty x range [4.94066e-324:4.94066e-324], adjusting [4.94066e-324:4.94066e-324] "chameleonconfidence.gplot", line 15: x_min should not equal x_max!

can me this?

this works me.

set xrange [-1:4] title="ratio of time taken" plot "chameleonconfidence.dat" using ($0):2:4:3:xticlabels(1) yerrorbars title title

the xtic function doesn't replace x-values in file -- automagic field can add using specification add xticlabels on axis. basically, need line number ($0) x value , set (moving xtic(1) end of using spec)

c++ - Troubles when compiling phash program -

-
here (probably) simple problem: i'm trying use perceptual hashing library phash ubuntu 11.10. had ffmpeg installed, way i've done: sudo apt-get install libphash0 sudo apt-get install libphash0-dev then tried compile program: #include <iostream> #include <phash.h> using namespace std; int main() { ulong64 myhash=0; ph_dct_imagehash("test.jpg", myhash); cout<<myhash<<endl; } when compiling, prints out: undefined reference `ph_dct_imagehash' any suggestion? should do? in advance! matteo monti you forgot link phash library, linker cannot find function. try adding -l phash gcc command line (or update makefile). if doesn't work, maybe you'll need specify library path (the location of *.a file) using -l "/usr/lib/"
