How to set the y-axis distance between point to point?
未命名.jpg
there is a point before the point6 .The point is currently unavailable, because it was so long, how should I do?
Code:
var a = new Ext.chart.Chart({
            width: '100%',
            height: '100%',
            store: store,
            animate: true,
            legend: {
                position: 'right'
            },
            interactions: [
                {
                    type: 'iteminfo',
                    listeners: {
                        show: function (interaction, item, panel) {
                            var storeItem = item.storeItem;
                            panel.setHtml(['<ul><li><b>time: </b>' + storeItem.get('date') + '</li>',
                                '<li><b>temperature: </b> ' + storeItem.get('temperature') + '</li>',
                                '<li><b>pulse: </b> ' + storeItem.get('pulse') + '</li></ul>'].join(''));
                        }
                    }
                }
            ],
            axes: [{
