- Hi,
-
- When I am trying to plot my data which looks like
-
- 3.041000 3.720E-27
- 3.261900 1.240E-26
- 3.688000 1.720E-26
- 4.211400 1.520E-27
- 5.007400 1.430E-26
- 5.029000 1.620E-26
- 5.621000 1.210E-26
- 5.654700 1.190E-28
- 6.794000 2.460E-26
- 6.057000 6.170E-27
- 6.907700 1.240E-29
- 7.114567 7.770E-23
- 7.471000 3.170E-26
- 7.785000 1.900E-25
- 7.916000 5.120E-27
-
- gnuplot is treating the y axis as zeros and drawing a line on the
- screen.
- Well I thought by deviding all the y values as
- f(y) = y/1.0e-24 /* an arbitrary number supposedly a median of the y values*/
- gnuplot complines undefined y value.
-
- My command script is as follows.
-
- set terminal tek40xx
- set noxzeroaxis
- set data style lines
- set logscale y
- set output "x.plt"
- pop(y) = y/1.0e-26
- plot 't1.dat_bak',pop(y) with errorbars
- plot 't1.dat_bak',pop(y)
- quit
-
- %gnuplot < commands
- line 7: undefined variable: y
-
- line 8: undefined variable: y
-
- %
-
- Actually the data is spectroscopy data and I need to plot (!!if possible !!)
- as a spectrum.
-
- Any ideas at the earliest of your conveniance.
-
- Thanks in advance.
