Greetings,

I have created a graph with the help of GNUPLOT. It's working good. Problem is that I want to show Download /Upload Data in GB in LABELS and its showing in bytes. How can I add formulat to dvidie teh bytes values in LABELS ?


My GNUPLOT CFG file is as follow

reset
set terminal jpeg
set output "/var/www/radius.jpg"
set xdata time
set timefmt "%Y-%m-%d"
set format x "%d/%m"
set xtics 86400
set xtics rotate by -45
set xlabel "Date (day/month)"
set ylabel "Data Downloaded in MB"
set title "username - $1 - Download/Upload Report $FULLMONTH $YEAR \nThis report was created on $NOW\nPowered by Syed Jahanzaib"
set key outside
set grid
set style data histogram
set style histogram cluster gap 1
set style fill solid
set boxwidth 0.9
plot "/tmp/userdata.txt" using 1:(\$2/1024/1024/1024) w boxes title "Download" lw 15, \
"/tmp/userdata.txt" using 1:(\$3/1024/1024/1024) w boxes lw 6 title "Upload", \
"/tmp/userdata.txt" using 1:(\$2/1024/1024/1024):2 w labels


and data file is as follows which have the values

cat /tmp/userdata.txt
[date]     [Download]   [Upload]
2015-05-01 4474024942   4254178590
2015-05-02 2414432830   106085629
2015-05-03 577354896    30842461
2015-05-04 440391880    25135023
2015-05-05 9393497144   1455046027
2015-05-06 840315630    72266841

2015-05-10 39158708     55439832


with this config, I am getting LABEL values in bytes, and I want to show them in GB in LABELS.
