Formatting problem

[Mauricio Rodriguez]

Hello I have a Material ScatterChart with 3 axes, the format of two percent axes are ok (#,##%),

but for another axis (Promedio) only display one fraction digit when I have 2, round second fraction digit.

Formatter don't work for me.

Thanks in Avance. 

// ScatterChart3

       var data = google.visualization.arrayToDataTable(JSONData.cap);

       var formatter = new google.visualization.NumberFormat({ 

 pattern: '#', 

 fractionDigits: 2

});

formatter.format(data, 2); // format column 3

//console.log(JSONData.cap);

var options = {

chart: {

title: 'Desglose',

subtitle: 'Avance / Promedio'

},

width: 800,

height: 400,

hAxis: {title: 'Ciclos', minValue: 0, maxValue: 10, format: '#', 

viewWindowMode:'explicit',

 viewWindow:{

   min:1,

   max:10

 }

},

vAxes: [{title: 'Avance', minValue: 0, maxValue: 1, format: '#.##%',

viewWindowMode: 'explicit',

 viewWindow: {

   min: 0,

   max: 1

 }

},

//{title: 'Asignaturas', minValue: 0, maxValue: 1, format: '#.##'},

{title: 'Promedio', minValue: 0, maxValue: 10, format: '#.##',

viewWindowMode: 'explicit',

 viewWindow: {

   min: 0,

   max: 1

 }

}

],

series: {

//0: {axis: 'Creditos'},

//1: {axis: 'Asignaturas'},

2: {axis: 'Promedio'}

},

axes: {

           y: {

             'Creditos': {label: 'Avance'},

             'Promedio': {label: 'Promedio'}

           }

}

};

var chart = new google.charts.Scatter(document.getElementById('ScatterChart3'));

chart.draw(data, google.charts.Scatter.convertOptions(options));
