chartist to display nice pie...

You should only create a chart instance once then update it with new data. Keep in mind that this library does not work correctly if visualization scaling is enabled.

Code:

$(function(){   var chart;   grp.listen('20/3/200', function(obj) {     var classImage = 'pie1';     var idChart = 'chart1';     const variableCourbes = ["20/3/0", "20/3/1", "20/3/2", "20/3/3", "20/3/4"];         var labelTab = [];     var serieTab = [];     var separateurNom = ' ';         for (let i = 0; i < variableCourbes.length; i++) {       var id = Scada.encodeGroupAddress(variableCourbes[i]);       var obj = objectStore.getObject(id);       var nom = obj.name.split(separateurNom)[0];             labelTab.push(nom);       serieTab.push(obj.value);     }         var data = {       labels: labelTab,       series: serieTab     };     var options = {       width: 300+20,       height: 300+20,       donut: true,       donutWidth: 50,       donutSolid: true,       startAngle: 270,       showLabel: true     };     if (chart) {       chart.update(data);     }     else {       var plans = $('.' + classImage)[0]       plans.innerHTML = '<div class="" id="'+ idChart + '"></div>';       chart = new Chartist.Pie('#'+idChart, data, options);     }   }, true); });

Hi @admin, why it doesn't work if visualitzation sacling is enabled? Is there any way to solve it?
Thanks!
