Highcharts - Donut Chart Not working
Closed

    Hi there,

    I am a software developer and found a bug/problem in the premium wpDatatables (and the charts) that I am using in one website and I noticed that the Highcharts - Donut Chart is not working properly.

    As you know (and from the highcharts official docs) the Donut Chart should support more than 2 columns. Even according to the Donut Chart thumbnail in the Wizard it shows as so.

    Can you kindly fix this bug please?

    Hi Oliver,

    This is how our HighCharts Donut Chart type is working by default in our Plugin.

    If you check our Documentation Page about the HighCharts Donut Chart, our developers pointed out that in our Plugin's HighCharts Donut Chart, you can only choose exactly two columns as a strict requirement.

    The first chosen column provides the labels for each 'slice' of the donut.

    And the additional column must be numeric, it will provide the 'slices serie values'.

    I tried to find the part of the HighCharts Documentation as you described, that it should support more than 2 columns, but I can't seem to find it.

    I just found demos such as this one - where they wrote how it is very similar to how the pie chart works - and we know for the pie chart, that can also only take 2 columns as the strict requirement.

    Could you please send us an URL or point us to the part where they pointed out that detail and I can pass it to our developers?


    2. That thumbnail preview in our Chart Wizard, to be honest I am not able to clearly see does it show multiple numeric series - or if it is just one numeric column being rendered as multiple slices in that donut, the image has very low resolution.

    I will certainly ask our developers about that, too, just to be sure and going to confirm it.

    Thank you.
