gnuplot - Positioning labels on x axis -

i trying plot simple graph, x , y coordinates, how axis labels not quite wish.

• how can change '1e+08' , on true value, 100000000
• how can shift labels of xtics down don't obscure graph?
• can print coordinates in graph of certian points, example dip between 2014-05-10-04-00 , 2014-05-10-08-00?
• how can 1 add more intervals in labels of x axis?

here input i'm using:

reset clear set output "bytesovertime.png" set title "evolution of bytes on time" set ylabel 'bytes' set xlabel 'time' set key off set term png set xdata time set timefmt "%y-%m-%d-%h-%m" set format x "%y-%m-%d-%h-%m" set xtics rotate 90 nomirror set datafile separator ' ' set logscale y plot "timebytesaverage.out" using 1:2 

and file if needed test: http://pastebin.com/raw.php?i=qqpejj4v

how can change '1e+08' , on true value, 100000000

set format y "%f" 

or, give decimal numbers:

set format y "%.0f" 

you may have at

set format y "%.0s%cbyte" 

which create mbyte, gbyte, ... (see right y-axis in plot) however, base of 1000, not 1024.

how can shift labels of xtics down don't obscure graph?

set xtics rotate 90 nomirror right 

will right-align (left-flush) tic marks

can print coordinates in graph of certian points, example dip between 2014-05-10-04-00 , 2014-05-10-08-00?

if know coordinates, yes:

set xtics add ("high" "2014-05-09-23-30", "low" "2014-05-10-22-30" ) 

the general syntax is:

set xtics add (  <label1> <position1>, <label2> <position2> , ...) 

this add list of labels automatically generated labels. if omit word add, there no automatically generated labels, in list.

how can 1 add more intervals in labels of x axis?

set xtics 3600 

will generate label every 3600 seconds, i.e. every hour. not work log scale axes.

set mxtics 2 

will cause gap between 2 major (labeled) tics being divided 2 smaller gaps, i.e. 1 minor tic mark between 2 major ones. (however, seems not necessary here, gnuplot decides use 2 on it's own)

and here result:

note added

set y2tics set y2range[1e8:1e12] set format y2 "%.0s%cbyte" set logscale y2 

to demonstrate special format on right y-axis.

and way: format of labels on y-axis independent format in data file.

set timefmt "%y-%m-%d-%h-%m" defines format inside file

set format x "%y-%m-%d-%h-%m defines format in plot. ou may set format x "%y-%m-%d %h:%m more readable.
