我想在高库存股票图表中动态更改图表类型。
基本上,我想将ohlc图表类型更改为线,面积,样条,areaspline,列,条形烛台等。我通过添加外部下拉列表并基于下拉列表中选择的值来实现此操作,正在将系列类型更改为其各自的值,但是这里存在问题。
ohlc和烛台的数据格式与其他格式不同,因此,即使图表以线,面积等形式呈现,其值也不正确。
是否可以在不更改数据格式的情况下添加其他图表类型,或者是否必须更改数据格式,请告诉我如何更改xaxis,因为其他数据格式需要提及外部xaxis。
感谢您的帮助。

您可以设置options.chart.type = 'column'; //chart type
options.chart.renderTo = 'container';
options.chart.type = 'column';
var chart1 = new Highcharts.Chart(options);
如果要更改xAxis和数据格式,则需要更新options
变量
$(function () {
// Create the chart
var options = {
chart: {
events: {
drilldown: function (e) {
if (!e.seriesOptions) {
var chart = this;
// Show the loading label
chart.showLoading('Loading ...');
setTimeout(function () {
chart.hideLoading();
chart.addSeriesAsDrilldown(e.point, series);
}, 1000);
}
}
},
plotBorderWidth: 0
},
title: {
text: 'Change chart type',
},
//
subtitle: {
text: 'Subtitle'
},
//
xAxis: {
type: 'category',
},
//
yAxis: {
title: {
margin: 10,
text: 'No. of user'
},
},
//
legend: {
enabled: true,
},
//
plotOptions: {
series: {
pointPadding: 0.2,
borderWidth: 0,
dataLabels: {
enabled: true
}
},
pie: {
plotBorderWidth: 0,
allowPointSelect: true,
cursor: 'pointer',
size: '100%',
dataLabels: {
enabled: true,
format: '{point.name}: <b>{point.y}</b>'
}
}
},
//
series: [{
name: 'Case',
colorByPoint: true,
data: [3, 2, 1, 3, 4]
}],
//
drilldown: {
series: []
}
};
// Column chart
options.chart.renderTo = 'container';
options.chart.type = 'column';
var chart1 = new Highcharts.Chart(options);
chartfunc = function()
{
var column = document.getElementById('column');
var bar = document.getElementById('bar');
var pie = document.getElementById('pie');
var line = document.getElementById('line');
if(column.checked)
{
options.chart.renderTo = 'container';
options.chart.type = 'column';
var chart1 = new Highcharts.Chart(options);
}
else if(bar.checked)
{
options.chart.renderTo = 'container';
options.chart.type = 'bar';
var chart1 = new Highcharts.Chart(options);
}
else if(pie.checked)
{
options.chart.renderTo = 'container';
options.chart.type = 'pie';
var chart1 = new Highcharts.Chart(options);
}
else
{
options.chart.renderTo = 'container';
options.chart.type = 'line';
var chart1 = new Highcharts.Chart(options);
}
}
$('#change_chart_title').click(function(){
var chart = $('#container').highcharts();
//alert('Chart title changed to '+new_title+' !');
});
