Pie in Percentages

[arthipesaParticipant]

Dear JQCharts Experts,

I hope I posted in the right place to ask, I would like to create a full 100% pie charts, which I successfully did, but instead of values I would like to show the percentages of the slices in the label, in the example i only saw, yet I don’t see how to get the actual percentages proportion.

formatFunction: function (value){
    if (isNaN(value)) return value;
}

Hi arthipesa,

Actually, this is demonstrated in the Chart’s first demo: http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxchart/javascript_chart_pie_series.htm?arctic

HI Peter,

Thanks but that’s not what I meant, I mean in the example the solution for showing number as percentages is only to add the suffix of “%”, which in that example the total of those are 100%, but in many case, the numbers provided as the data source isn’t actually two digits (in which supposedly total of 100).

Original example:

Internet Explorer, 33.3
Firefox, 26.5
Chrome, 25.4
Safari, 7.0
Opera, 4.6
Other, 3.2

What I meant as datasource are:

Internet Explorer, 133.3
Firefox, 126.5
Chrome, 125.4
Safari, 2317.0
Opera, 3414.6
Other, 4513.2

Hi arthipesa,

Then, calculate the percentage. Sum all values and get the percentage of each value using Mathematics for percentage calculation.

Yes Peter,
I really would like to do so, but inside the var settings.
Or is this mean that I can’t do something like

formatFunction: function (value, total){
   return (value/total*100) + '%';
}

in the var settings?

Hi arthipesa,

Chart does not calculate the total which means that your function definition is incorrect. You should write code which calculates Total.
