[Solved]-Getting numbers on Y-axis to show up as percentages with code from a Highcharts code generator tool?-Highcharts

This "tool code" is just regular Highcharts code, and does nothing more than generate it for you.

For the first chart you can use valueSuffix to add a percentage sign after the value. Code:

plotOptions: {
    column: {
        tooltip: {
            valueSuffix: '%'
        }
    }
}

For the second chart you can use the global thousandSep option to get comma separators. Code:

Highcharts.setOptions({
    lang: {
        thousandsSep: ','
    }
});

See this JSFiddle demonstration of both code segments.
