    Default Treemap not working

    Treemap not working


    Hi,

    I'm trying to use the treemap chart with a in memory TreeStore and it does not work, here is my code :

    Code:
    Ext.setup({
        onReady: function() {
            new Ext.chart.Panel({
                fullscreen: true,
                chart: new Ext.chart.Chart({
                    store: new Ext.data.TreeStore({
                        fields: ['name', 'area', 'children', 'id'],
                        data: {
                            name: 'Budget',
                            area: 1,
                            id: 'root',
                            children: [{
                                name: 'Defense',
                                id: 'defense',
                                area: 0.5,
                                children: []
                            }, {
                                name: 'Education',
                                id: 'education',
                                area: 0.3,
                                children: []
                            }, {
                                name: 'Debt',
                                id: 'debt',
                                area: 0.2,
                                children: []
                            }]
                        },
                        proxy: 'memory'
                    }),
                    series: [{
                        type: 'treemap',
                        layout: 'squarified',
                        orientation: 'horizontal',
                        rootName: 'Budget',
                        titleField: 'name',
                        areaField: 'area'
                    }]
                })
            });
        }
    });
    Can you tell what am I missing ? Thanks

    For the TreeStore you shouldn't use the data config, you should use the root config.

    Thanks for you answer, I tried to change data to root in my store but it does not change anything :

    Code:
    Ext.setup({
        onReady: function() {
            new Ext.chart.Panel({
                fullscreen: true,
                chart: new Ext.chart.Chart({
                    store: new Ext.data.TreeStore({
                        fields: ['name', 'area', 'children', 'id'],
                        root: {
                            name: 'Budget',
                            area: 1,
                            id: 'root',
                            children: [{
                                name: 'Défense',
                                id: 'defense',
                                area: 0.5,
                                children: []
                            }, {
                                name: 'Education',
                                id: 'education',
                                area: 0.3,
                                children: []
                            }, {
                                name: 'Dette',
                                id: 'debt',
                                area: 0.2,
                                children: []
                            }]
                        },
                        proxy: 'memory'
                    }),
                    series: [{
                        type: 'treemap',
                        layout: 'squarified',

                    }]
                })
            });
        }
    });
