[Solved]-Highcharts legend font sizes-Highcharts

That theme uses font instead of fontSize. So, it's legend is defined as:

 legend: {
              itemStyle: {
                 font: '9pt Trebuchet MS, Verdana, sans-serif',
                 color: '#A0A0A0'
              },
              itemHoverStyle: {
                 color: '#FFF'
              },
              itemHiddenStyle: {
                 color: '#444'
              }

        },

If you define your's with both font and fontSize, it'll work (seems like a bug to me, but maybe it's a feature):

 legend: {
              itemStyle: {
                 fontSize:'20px',
                 font: '20pt Trebuchet MS, Verdana, sans-serif',
                 color: '#A0A0A0'
              },
              itemHoverStyle: {
                 color: '#FFF'
              },
              itemHiddenStyle: {
                 color: '#444'
              }

        },

I assume the title has the same thing going on.
