通过 amchart 从 X 轴中删除银行假日

Question

我有这样的日期数据，没有2017/07/17，2017/07/16，2017/07/15因为它们是银行假期。

chartData = new Array();
chartData[0] = new Array();
chartData[0].closePrice = 1207;     
chartData[0].date =  new Date("2017/07/12");
chartData[1] = new Array();
chartData[1].closePrice = 1227;     
chartData[1].date =  new Date("2017/07/13");
chartData[2] = new Array();
chartData[2].closePrice = 1216;     
chartData[2].date =  new Date("2017/07/14");
chartData[3] = new Array();
chartData[3].closePrice = 1234;     
chartData[3].date =  new Date("2017/07/18");

我使用此图表数据作为数据提供者来制作图形。

var dataSet = new AmCharts.DataSet();
dataSet.dataProvider = chartData;
dataSet.categoryField = "date";
chart.dataSets = [dataSet];

var stockPanel = new AmCharts.StockPanel();
stockPanel.title = "Stock Main";
stockPanel.id = "stockPanel";
stockPanel.showCategoryAxis = false;
stockPanel.recalculateToPercents = "never";
var valueAxis = new AmCharts.ValueAxis();
valueAxis.dashLength = 5;
stockPanel.addValueAxis(valueAxis);
stockPanel.categoryAxis.dashLength = 5;
stockPanel.categoryAxis.equalSpacing = true; // it doesn't work ....
var graph = new AmCharts.StockGraph();
graph.type = "line";
graph.valueField = "closePrice";
stockPanel.addStockGraph(graph);

然而2017/07/15，2017/07/162017/07/16画在X轴上，即使没有数据。

连.equalSpacing看起来都是徒劳的。

我怎样才能删除它???

Answer 1

您必须在股票图表的categoryAxesSettings属性中设置equalSpacing才能正常工作。

//object-based setup
chart.categoryAxesSettings = new AmCharts.CategoryAxesSettings();
chart.categoryAxesSettings.equalSpacing = true;
//makeChart version
AmCharts.makeChart("chartdiv", {
// ...
"categoryAxesSettings": {
"equalSpacing": true
},
// ...
});
