Scale the values/labels on an axis

Question

Ive a data set with the below range of values,

x from 0 to 100

y from 0.0 to 10.0^10

I'm using plot function to draw the graph plot(x, y). The graph is drawn but with the below warning of converting the y values from integer to float.

multiplot> set ytics in scale  1.4 border mirror ( "0" 0,  "1e+10" 10000000000,  "2e+10" 20000000000,  "3e+10" 30000000000,  "4e+10" 40000000000,  "5e+10" 50000000000,  "6e+10" 60000000000,  "7e+10" 70000000000) textcolor rgb "#262626" font ",10";
line 2: warning: integer overflow; changing to floating point

The y values are already in float, but not sure why this warning is thrown. Is it possible to set explicit formatting(Format specifiers) on the axis or ytics ?

A similar question is posted in here. But seems like those are gnuplot commands/options. How to use the same options in octave plot ?

@Andy, I've updated the post with the sample code and the resulting graph. Hope it helps. — NEB

Is it this maybe what you are looking for? Although, having 1e10 written as 10000000000 is not very "user-friendly".

set xrange[0:100]
set yrange[0:1e10]

set format y "%.0f"

plot exp(x)
