#2918 — gnuplot dates are missing in graph

Greetings to all,

I am using gnuplot to generate graphs by taking data from the following file

root@rm:/temp# cat data.txt
2015-04-1  23248972
2015-04-2  67012325
2015-04-3  66622333
2015-04-4  61943333
2015-04-5  47033536
2015-04-6  36863346
2015-04-7  56863634
2015-04-8  46861736
2015-04-9  16863836
2015-04-10 93683693
2015-04-11 93638693
2015-04-12 93638693
2015-04-13 23638693
2015-04-14 13638693
2015-04-15 69363893
2015-04-16 33638693
2015-04-17 93638693
2015-04-18 33638693
2015-04-19 13638693
2015-04-20 93638693
2015-04-21 93638693
2015-04-22 63638693
2015-04-23 2638693
2015-04-24 93638693
2015-04-25 93638693
2015-04-26 8638693

and gnuplot file is as follows


# gnuplot script file for plotting data
#!/usr/bin/gnuplot
reset
set terminal jpeg enhanced
set output "/var/www/gplot.jpg"
set xdata time
set timefmt "%Y-%m-%d"
set format x "%d/%m"
set xlabel "Date (day/month)"
set ylabel "Data Downloaded in MB"
set title "User Download Report as requested"
set key below
set grid
set boxwidth 0.5
set style fill solid
plot "/temp/data.txt" using 1:($2/1024/1024) with impulse title "Daily Usage" lw 10


Graph is generating but Date Lables are missing as per day count. like it should show each day label on each bar, is it possible?

"set xtics 86400" will set the increment to 86400 seconds and you get 
one label per day. The incr. must be give in seconds.
