How to use DataLabelManager class to create datalabels in custom power bi visual?

Hi, @rakeshkamble1 

Here is the usage of 'DataLabelManager':powerbi-visuals-utils-chartutils/data-label-manager.md at master · microsoft/powerbi-visuals-utils-c...

The DataLabelManager helps to create and maintain labels. It arranges label elements using the anchor point or rectangle. Collisions between elements can be automatically detected and as a result elements can be repositioned or get hidden.

Dear Janey,

Thank you for your response. I have followed the code but unable to understand how I can show customized data labels on bar chart. Tis article only shows how to get the datalabel, but I would require more info on how we can display the datalabels on bar chart.

Dear Janey,

Thank you once again for your reply.

I would require an example where datalabels should be shown on bar chart using custom visual. I have already created one bar chart, but not able to understand how to incorporate DataLabels and Legends into it.

If I could get any code reference then it's highly helpful.

Dear Janey,

Thank you for sharing the information.

I have issue with below line of code while adding legend data.

interface ViewModel{

    dataPoints: Datapoint[];

    legendData: LegendData;

    dataLabelsData: LabelEnabledDataPoint;

};

let legendData : LegendData = {

            dataPoints: [],

            title: "Testing"

        }

        legendData.dataPoints.push({

            label: "Legend Test",

            color: "blue",

            selected: false,

            identity: null

        });

        this.legend.drawLegend(this.viewModel.legendData, options.viewport); --Issue here in customVisualsHost.bundle.min.js file 

Can you please let me know where i'm doing wrong parameter insertion?
