Setting the padding for the hAxis

[Ron_!]

Hello,

My chart is working fine as expected except that the hAxis labels have very little or no padding in between the chart itself and the legend. Is there a way to increase it? Thanks for any help!

Image attached.

options:

var options = {
          colors:['rgb(32, 170, 188)', 'rgb(32, 188, 77)'],
          lineWidth:4,
          areaOpacity: 0.15,
          width:$(window).width() * 0.5,
          height:$(window).width() * 0.25,
          animation: {
               "startup": true,
               duration: 1200,
               easing: 'out',
          },
          fontName: 'Open Sans',
          legend: {
            position:'bottom',
          },
          chartArea:{
            width:'90%',
            height:'80%',
          }
        };
