日期选择器未设置最大值和最小值

Question

I'm setting my minimum value and max value using the sample data in my push function to show it in the date picker. But when I click the date picker, it shows the wrong min and max value, what's wrong with my code? I used this to get the min and max value

"minDate": dataProvider[0].date, "maxDate":dataProvider[dataProvider.length - 1].date,

 var chartData1 = []; generateChartData(); function generateChartData() { chartData1.push( { "date": "2012-10-11", "value": 33 }, { "date": "2012-12-12", "value": 50 }, { "date": "2012-12-13", "value": 10 }, { "date": "2012-12-14", "value": 100 }, { "date": "2013-12-15", "value": 30 }); } var chart = AmCharts.makeChart("chartdiv", { "type": "stock", "extendToFullPeriod": false, "dataSets": [{ "title": "first data set", "fieldMappings": [{ "fromField": "value", "toField": "value" }, { "fromField": "volume", "toField": "volume" }], "dataProvider": chartData1, "categoryField": "date" }], "panels": [{ "showCategoryAxis": false, "title": "Value", "percentHeight": 70, "stockGraphs": [{ "id": "g1", "valueField": "value", "comparable": true, "compareField": "value", "balloonText": "[[title]]:<b>[[value]]</b>", "compareGraphBalloonText": "[[title]]:<b>[[value]]</b>" }], "stockLegend": { "periodValueTextComparing": "[[percents.value.close]]%", "periodValueTextRegular": "[[value.close]]" } }, { "title": "Volume", "percentHeight": 30, "stockGraphs": [{ "valueField": "volume", "type": "column", "showBalloon": false, "fillAlphas": 1 }], "stockLegend": { "periodValueTextRegular": "[[value.close]]" } } ], "chartScrollbarSettings": { "graph": "g1" }, "chartCursorSettings": { "valueBalloonsEnabled": true, fullWidth: true, cursorAlpha: 0.1 }, "periodSelector": { "position": "left", "periods": [{ "period": "MM", "selected": true, "count": 1, "label": "1 month" }, { "period": "YYYY", "count": 1, "label": "1 year" }, { "period": "YTD", "label": "YTD" }, { "period": "MAX", "label": "MAX" }] }, "dataSetSelector": { "position": "left" } }); chart.addListener('rendered', function(event) { var dataProvider = chart.dataSets[0].dataProvider; $(".amChartsPeriodSelector .amChartsInputField").datepicker({ "dateFormat": "dd-mm-yy", "minDate": dataProvider[0].date, "maxDate": dataProvider[dataProvider.length - 1].date, "onClose": function() { $(".amChartsPeriodSelector .amChartsInputField").trigger('blur'); } }); });

From the minDate and maxDate documentation :

minDate

Multiple types supported:

• A date object containing the minimum date.

• A string in the format defined by the dateFormat option , or a relative date.

Your dates are in the format yyyy-mm-dd , but your dateFormat option is dd-mm-yy .

That said, notice the documentation mentions that they can be date objects. You could convert your strings to date objects by wrapping them in new Date(...) .

"minDate": new Date(dataProvider[0].date),
"maxDate": new Date(dataProvider[dataProvider.length - 1].date),

 var chartData1 = []; generateChartData(); function generateChartData() { chartData1.push({ "date": "2012-10-11", "value": 33 }, { "date": "2012-12-12", "value": 50 }, { "date": "2012-12-13", "value": 10 }, { "date": "2012-12-14", "value": 100 }, { "date": "2013-12-15", "value": 30 }); } var chart = AmCharts.makeChart("chartdiv", { "type": "stock", "extendToFullPeriod": false, "dataSets": [{ "title": "first data set", "fieldMappings": [{ "fromField": "value", "toField": "value" }, { "fromField": "volume", "toField": "volume" }], "dataProvider": chartData1, "categoryField": "date" }], "panels": [{ "showCategoryAxis": false, "title": "Value", "percentHeight": 70, "stockGraphs": [{ "id": "g1", "valueField": "value", "comparable": true, "compareField": "value", "balloonText": "[[title]]:<b>[[value]]</b>", "compareGraphBalloonText": "[[title]]:<b>[[value]]</b>" }], "stockLegend": { "periodValueTextComparing": "[[percents.value.close]]%", "periodValueTextRegular": "[[value.close]]" } }, { "title": "Volume", "percentHeight": 30, "stockGraphs": [{ "valueField": "volume", "type": "column", "showBalloon": false, "fillAlphas": 1 }], "stockLegend": { "periodValueTextRegular": "[[value.close]]" } } ], "chartScrollbarSettings": { "graph": "g1" }, "chartCursorSettings": { "valueBalloonsEnabled": true, fullWidth: true, cursorAlpha: 0.1 }, "periodSelector": { "position": "left", "periods": [{ "period": "MM", "selected": true, "count": 1, "label": "1 month" }, { "period": "YYYY", "count": 1, "label": "1 year" }, { "period": "YTD", "label": "YTD" }, { "period": "MAX", "label": "MAX" }] }, "dataSetSelector": { "position": "left" } }); chart.addListener('rendered', function(event) { var dataProvider = chart.dataSets[0].dataProvider; $(".amChartsPeriodSelector .amChartsInputField").datepicker({ "dateFormat": "dd-mm-yy", "minDate": new Date(dataProvider[0].date), "maxDate": new Date(dataProvider[dataProvider.length - 1].date), "onClose": function() { $(".amChartsPeriodSelector .amChartsInputField").trigger('blur'); } }); });
