how to handle large values in gnuplot

I have below sample file which has large values more than 10000000.

date,value1,value2,value3,value4
2009-06-01,16100834.94,20891965.33,15271434.3,9923084.09

I can plot the graph but in graph the values in Y axis are shown in exponential numbers. i.e.

10000000 = 1e+7

How can i display the Y range values in decimal numbers only instead of exponential.

---

use below before plot

gnuplot> set format y "10^{%L}"
gnuplot> set terminal postscript eps enhanced 
gnuplot> set ylabel "Y-AXIS" 2,0  

you will get the values in 10^. For other formats look at this link

Hope this helps.
