Adding "%" symbol in the gauge

[Andy H]

Anyone know of a way to add the "%" symbol after the data or number
rendered at the bottom of the gauge? I see you can format number as
percentages in other Google charts -- but I can't figure out a way to
do it with the gauge chart.

Thanks :-)

I did it by adding a formatter:
       
        var formatter = new google.visualization.NumberFormat(
                  {suffix: '%'});
              formatter.format(dataGauge, 1); // Apply formatter to second column

good luck =)
