you are requesting xtics explicitly:
fprintf(pipe, "plot 'data.d' using 1:xtic(1) t col, '' u 2 ti col, '' u 3 ti
col, '' u 4 ti col\n");
remove "xtic(1)" from the "plot" command and there should be no xtics
anymore.

so you want the xtic labels, but don't want the label values to be
plotted?
try this:
fprintf(pipe, "plot 'data.d' using 2:xtic(1) t col, '' u 3 ti col, '' u 4 ti
col\n");

'help plot using xtic' says:
xticlabels(N) is shorthand for xticlabels(stringcolumn(N))
so you may use
plot 'data2.dat' using 3:xtic(stringcolumn(1)." ".stringcolumn(2)) t col
to have the ytics start at '0' you need to set yrange, not ytics:
set yrange [0:*]
column 3 has no header, you need to tell gnuplot to use
the header of column '2' instead:
plot 'data2.dat' using 3:xtic(stringcolumn(1)." ".stringcolumn(2)) t
columnheader(2)

Everything worked great :) just had some glitches as i call gnuplot from C i use "this is the command so insidme i have to use ' ' " another thing what i need to do is set the value of ticks on top of them, is that possible? i have been looking around but haven't found suitable solution... I need to do that because my data are very different, there is y range from 0 to 25000 and more... -- View this message in context: http://old.nabble.com/gnuplot-tics-tp33900443p34016147.html Sent from the Gnuplot - User mailing list archive at Nabble.com. |

the options 'offset' and 'center' for the 'set ytics' command may be useful. rihii wrote: > > Everything worked great :) > > just had some glitches as i call gnuplot from C i use "this is the command > so insidme i have to use ' ' " > > another thing what i need to do is set the value of ticks on top of them, > is that possible? > i have been looking around but haven't found suitable solution... > > I need to do that because my data are very different, there is y range > from 0 to 25000 and more... > -- View this message in context: http://old.nabble.com/gnuplot-tics-tp33900443p34019022.html Sent from the Gnuplot - User mailing list archive at Nabble.com. |
