我正在使用amchart stock chart
function createStockChart() {
var chart = new AmCharts.AmStockChart();
var dataSet = new AmCharts.DataSet();
// make candlechart
dataSet.fieldMappings = [{
fromField: "open",
toField: "open"
}, {
fromField: "close",
toField: "close"
}, {
fromField: "high",
toField: "high"
}, {
fromField: "low",
toField: "low"
}, {
fromField: "volume",
toField: "volume"
}, {
fromField: "testValue",
toField: "testValue"
}];
dataSet.dataProvider = chartData;
dataSet.categoryField = "date";
// make line to be drawn on the candle stock
var dataSet2 = new AmCharts.DataSet();
dataSet2.fieldMappings = [{
fromField: "close",
toField: "value"
}];
dataSet2.color = "#33888a";
dataSet2.dataProvider = chartData;
dataSet2.compared = false; // if I made here true, the line appears but it will be shown as percentage!!.
dataSet2.title = "Open";
dataSet2.categoryField = "date";
我想在蜡烛图上划一条线。
如果我将true
用于compared
字段,则该线条会显示在蜡烛部分上,但Y轴会变为百分比。
这是正确的,因为它是用于比较功能。
但是我想将图表附加起来不是为了比较。
如何在蜡烛图上简单画一条线???
答案 0 :(得分:1)
您可以在面板对象中将recalculateToPercents
设置为"never"
,以防止图表使用百分比,只需添加该行。这在the knowledge base
这里是fiddle that illustrates this。它使用JSON设置,但基于对象的设置类似。
