Chart - Donut and Pie (legend)

[Alexandru - Paul]

Hello!

I'm facing with a problem right now. 

I tried to add the legend for the pie and the donut, but unfortunately it doesn't work.

My first try was to add legend inside of chart like example below:

$chart = new \Kendo\Dataviz\UI\Chart('chart');
        $chart->dataSource($dataSource)
            ->autoBind(TRUE)
            ->tooltip($tooltip)
            ->addSeriesItem($seriesPieDonut)
            ->legend(array('visible' => true))
            ->seriesDefaults($seriesDefaults);

Also my second try was to add the legend into series like example below:

$seriesPieDonut = new \Kendo\Dataviz\UI\ChartSeriesItem();
        $seriesPieDonut->field('datapoint')->visibleInLegend('visible');

 

Unfortunately the result is the same.

Maybe you guys have a solution for thins situation. I will greatly appreciate! 

Thank you!

Yours,

Hi Alexandru-Paul,

In general, the legend of the chart should be shown automatically. However, when the chart is bound to remote data, you would have to specify it via the visibleInLegend option. However, the argument that it accepts is a field name. This field name should be either true or false. In the current set-up, you would have to introduce a field called "visible" and the JSON data would look like as follows:

{
          "year": 2009,
          "resolution": "1024x768",
          "share": 36,
          "visibleInLegend": false,
          "order": 1
        },{
          "year": 2009,
          "resolution": "Other",
          "share": 64,
          "visibleInLegend": true,
          "order": 2,
          "color": "#ccc"
        }

I hope you find this helpful.
