Discover how to implement custom data filtering in an Angular controller

Help needed: How can I remove decimals, add $ symbol in an Angular controller? Any ideas?

$scope.data = [{
        "key": " Logo",
        "color": "#004400",
        "values": [
            [0, parseInt($scope.myappslogo)]
        ]
    }, {
        "key": "Sell",
        "color": "#00cc00",
        "values": [
            [0, parseInt($scope.myapps.sell)]].$filter('currency')
    }, {
        "key": "Total",
        "color": "#009900",
        "values": [
            [0, parseInt($scope.myapps.amount)] | currency
        ]
    }

];

Answer №1

Using the $filter correctly looks like this:

$filter('currency')($scope.myapps.amount);

You also have the option to include additional parameters:

$filter('currency')(amount, symbol, fractionSize)

Based on that, it seems like you're looking for something similar to this:

$filter('currency')($scope.myapps.amount, '$', 0);

See more in ngdocs

If you have an array of values, you can create a function with the above code and map it to the array.
For example:

function mapCurrency(n) {
    return $filter('currency')(n, '$', 0);
}

tranformedValues = $scope.data[0].values[0].map(mapCurrency);

Answer №2

I found the answer! Inside the d3 option, I can use the filter as shown below:

$scope.options = {
          chart: {
            type: 'multiBarHorizontalChart',
            height: 150,
            x: function (d) {
              return d[0];
            },
            y: function (d) {
              return d[1];
            },
            stacked: true,
             xAxis: {
                    showMaxMin: true
                },
             yAxis: {
                    axisLabel: 'Values',
                    tickFormat: function(d){
                        return d3.format('$')(d);
                    }
             }
          }
        };
