You can use a DataView to make this dynamic:
// get min/max from column 1
var range = data.getColumnRange(1);
var view = new google.visualization.DataView(data);
view.setColumns([0, 1, {
type: 'string',
role: 'style',
calc: function (dt, row) {
var val = dt.getValue(row, 1);
if (val == range.max) {
return '#d51711'; // max
}
else if (val == range.min) {
return '#11d517'; // min
}
else {
return '#f9f107'; // all others
}
}
}]);
You need to recalculate range whenever your data changes. Use view in
place of data when drawing the chart.
