Do you know how to define that all the numbers on the Y axis should be
integers?

You have to set the format of the y-axis like so:

$graph->set(y_number_format => '%d');

Where '$graph' is the GD::Graph object you previously
created via the new method.

Hi I used the formula

$Y_max=(int($Y_max/8)+2)/8;

And it worked, so the Y_max is higher than the actual Y_max of the dataset
