Full example here

Options

• chartType: string representing one of chart types supported by ChartJS (line, bar, radar, pie, polar-area, doughnut)
• chartOptions: options object to be passed to ChartJS (check the official docs for more info)
• valueProperties: string or an array of strings each representing a path to property of the data object to be used as graph value. If array is passed, a graph will be drawn for each path. Strings should be in path.to.prop form
• valueDefaults: number or an array of numbers to be used as a default if the data point object doesn't contain property in the given path. Defaults to null, resulting in graph points not being drawn. If a single value is passed, it will be used as default for all graphs
• labelProperty: string or boolean. If string is passed, it will be used as a path to a property of the data object to be used as label. It should be in path.to.prop form. Passing true will generate auto incremented labels, starting at 0. Passing false will not display labels
• labelDefault: used if labelProperty is passed. Number representing default label value if the data point object doesn't contain property in the given label path
• series, click, hover, legend and colours are directly passed to Angular Chart directive

<!-- main.html -->

<flow-chart flow-id="flowId" limit="20">

        value-defaults="chart.valueDefaults"
        label-property="chart.labelProperty"
        chart-type="line"
        chart-options="chart.options"
        series="chart.series"
        legend="chart.legend">

</flow-chart>

/* main.js */

angular.module('ngFlowThingsApp')
    .controller('MainCtrl', function ($scope) {
        $scope.flowId = '< your Flow ID >';

        $scope.chart = {
            options: {
                animation: false
            },
            series: ['Inside Temperature', 'Outside Temperature'],
            valueProp: ['inside.temperature', 'outside.temperature'],
            /* or valueProp: 'inside.humidity' */
            valueDefaults: 0,
            /* or valueDefaults: [3, -7] */
            labelProperty: 'datetime'
            /* or labelProperty: true */
            legend: true
        }
