Questions
1

Hi,

i am creating some gauges on a loop and i get following error:
Error: attribute dy: Expected length, “NaN”.

       $.each(result.skillsProgress,function(indx,skprg){
            var gaugeElm = $("<div class='gauge skill-gauge' prcnt='"+skprg.percent+"'></div>").appendTo(sheetSkillsProgress).get(0);
            var skillGauge = app.gauge.create({
                el: gaugeElm,
                type: 'circle',
                value: 0,
                borderBgColor: '#dddddd',
                borderColor: '#0E5C6B',
                borderWidth: 15,
                valueText: skprg.skillName,
                valueFontSize: '1.8rem',
                valueFontWeight: "700",
                valueTextColor: '#0E5C6B',
                labelText: "%"+skprg.percent,
                labelTextColor: '#069CBC',
                labelFontSize: "1.6rem",
                labelFontWeight: "500"
            });

console:

var $$=Dom7;
var target=$$('.view-main .page-content');
var result={
  skillsProgress:[
    {skillName:'name 1',percent:0.1},{skillName:'name 2',percent:0.3},
    {skillName:'name 3',percent:0.6},{skillName:'name 4',percent:0.9},
    {skillName:'name 5',percent:1}
  ]
};
var tmpl=`
<div class="block text-align-center">
  {{#this}}<div class="gauge"></div>{{/this}}
</div>
`;
target.html(Template7.compile(tmpl)(result.skillsProgress));
result.skillsProgress.forEach(function(itm,inx){
  app.gauge.create({
    el: target.find('.gauge')[inx],
    value: itm.percent,
    valueText: itm.skillName,
    labelText: (itm.percent*100)+'%'
  });
});

My code works fine! i am using jquery and it is ok.
i found the issue, the error happens cause i used “rem” for valueFontSize and labelFontSize, the font size renders correctly on demanded rem size but the errors keep showing in console.

Regards.

Because it calculates offset based on passed textFontSize -> which should be a number representing pixels. Can’t do much math with '1.8rem' string
