Question

I’m wondering how to set axis step in a google chart built from JavaScript?
I use this to set min and max:

vAxis: {
title: 'temps (ms)',
    viewWindowMode: 'explicit',
    viewWindow: {
        max: 180,
        min: 0
    },
}

And I need to add an other constraint to fix vertical step to 0.1 for example.

Finally I found a trick using :

     vAxis: {
        title: 'temps (ms)',
        viewWindowMode: 'explicit',
        viewWindow: {
          //max: 180,
          min: 0,
        },
        gridlines: {
          count: 10,
        }
      }

It don’t set steps but instead, tell that

max / (nb steps) = count (here it’s 10)

So for example with max set to 180, each steps will have a value of 18 using count: 10.
