Removing "3,0" when manually placing data using [3,0]

[waliddoch]

I am currenlty experimenting with Echarts.

In certain cases, i want to write series-data to my chart in a different category, as explained in this part of the documentation - using the squared [] to choose the "column" where i want to use the data.

The problem is that when displaying the data on the chart I get it printed with commas 3,0,0,0. The parameter responsible for the output is formatter: '{c} {name|{a}}', and I couldn't find anything else that suits me via the documentation for the formatter part.

This is my code:

var app = echarts.init(document.getElementById('main-chart'));

var posList = [
    'left', 'right', 'top', 'bottom',
    'inside',
    'insideTop', 'insideLeft', 'insideRight', 'insideBottom',
    'insideTopLeft', 'insideTopRight', 'insideBottomLeft', 'insideBottomRight'
];

app.configParameters = {
    rotate: {
        min: -90,
        max: 90
    },
    align: {
        options: {
            left: 'left',
            center: 'center',
            right: 'right'
        }
    },
    verticalAlign: {
        options: {
            top: 'top',
            middle: 'middle',
            bottom: 'bottom'
        }
    },
    position: {
        options: echarts.util.reduce(posList, function (map, pos) {
            map[pos] = pos;
            return map;
        }, {})
    },
    distance: {
        min: 0,
        max: 100
    }
};

app.config = {
    rotate: 90,
    align: 'left',
    verticalAlign: 'middle',
    position: 'insideBottom',
    distance: 15,
    onChange: function () {
        var labelOption = {
            normal: {
                rotate: app.config.rotate,
                align: app.config.align,
                verticalAlign: app.config.verticalAlign,
                position: app.config.position,
                distance: app.config.distance
            }
        };
        app.setOption({
            series: [{
                label: labelOption
            }, {
                label: labelOption
            }, {
                label: labelOption
            }]
        });
    }
};

var labelOption = {
    normal: {
        show: true,
        position: app.config.position,
        distance: app.config.distance,
        align: app.config.align,
        verticalAlign: app.config.verticalAlign,
        rotate: app.config.rotate,
        formatter: '{c}  {name|{a}}',
        // formatter: '{name|{a}}',
