Bubble chart, legend problem

[Andrey]

Hi there, for some reason I can't force bubble chart to show legend, at the same time I'm able to see category name in the tooltip, could you please explain why, thanks.

        $("#Chart1").kendoChart({
                title: {
                    text: "Chart"
                },
                legend: {
                    visible: true,
                    position: "bottom"
                },
                dataSource: @{@Html.Raw(id)}ChartDataSource1,
                seriesDefaults: {
                    type: "bubble"
                },
                seriesColors: ["#004D5C", "#FF8700", "#38A660", "#E5D843", "#80BF34"],
                series:
                    [{
                        type: "bubble",
                        categoryField: "Field1",
                        xField: "Field2",
                        yField: "Field3",
                        sizeField: "Size",
                        colorField: "Color",
                        maxSize: 35,
                        minSize: 3,
                        visibleInLegendField: "true",
                        tooltip: {
                            visible: true,
                            format: "{2} {3}"
                        }

                    }
                    ]
               ,
                xAxis: {
                    //max: 1000,
                    labels: {
                        format: "{0}"
                    }
                },
                yAxis: {
                    //min: 80,
                    labels: {
                        format: "{0}"
                    }
                },
        });

Hello Andrey,

By design the legend shows the series name. Hence in order to display the legend in Kendo UI Bubble chart you should specify the series name. Like here: 

$("#Chart1").kendoChart({
  title: {
    text: "Chart"
  },
   //...
  series: [{
    name: "My series 1"
    type: "bubble",
    categoryField: "Field1",
     //....
  }]
  //....
});

Hi Iliana,
Adding name to the set of series doesn't resolve my problem, please see attached image.
I would like to have name for each series in the legend.
Thanks.

Hello Andrey,

In the provided code snippet I observed that you have definied only one series (that is why you get in the legend only SeriesName). Since the image shows 3 bubbles (which are actually the points of the series) I presume that you would like to show the name of each point. If this is your scenario I am afraid it is not supported (as I said in my previous post the legend shows the series name). In case I missed something please elaborate a bit more on the exact functionality you are trying to implement.

All the best,

Would be nice to be able to display point names in legend... We kinda need that too!

Hi Iliana,

I would like to know why do you think I have only one series. My datasource contains three records and inside ‘series’ I bind the fields from the datasource to my series, I thought that in that case I create three different series.

How then I can create three different series for every record in the datasource?

Thanks, Andrey.

Hi guys,

@Joe
I am afraid the implementation of this functionality is not in our immediate plans, however we may consider it for future releases. If you wish you may submit this idea as a feature request at our UserVoice portal. This way the community would be able to evaluate and commend it. The more votes it collect, the higher priority will have.

@Andrey
My assumption that you have only one series is due to the following definition:  

$("#Chart1").kendoChart({
  //....
  series:
  [{
    type: "bubble",
    categoryField: "Field1",
    xField: "Field2",
    yField: "Field3",
    sizeField: "Size",
    colorField: "Color",
    maxSize: 35,
    minSize: 3,
    visibleInLegendField: "true",
    tooltip: {
      visible: true,
       format: "{2} {3}"
    }
  }]
  //....
});

From the provided image it seems you get 3 bubbles, which as I said in my previous post are the points of the series, not the actual series. For your scenario I believe using bubble chart with grouped data will be suitable.
