How off skip ticks in line chart?

[kostya solovichenko]

In my chart 80-100 point on line, but ticks 10. Why? 
How off auto ticks on hAxis? 

I add costum ticks in option

hAxis: {
    ticks: ticks,
},

ticks = array on 80-100 elements. But show 10.
How show all ticks in hAxis?

try:

hAxis: {
  gridlines: { count: ticks }
}
