嗨,我想从鼠标悬停时出现的 amchart 图中删除红色气球。谁能帮我解决这个问题
我的代码是
var clicks =document.getElementById('clicks').value;
var cam_name =document.getElementById('cam_name').value;
var views =document.getElementById('views').value;
var camp_clicks =clicks.split('~');
var camp_names =cam_name.split('~');
var camp_imprs =views.split('~');
//var camp_clicks = [1,2,3,1.5,6,3,7];
var chart;
var chartData_camp = [];
/* var camp_names=['hi','hello','hw','r','u'];
var camp_costs=[1,2,3,4,5];
var camp_imprs=[1,2,3,4,5];
var camp_clicks=[1,2,3,4,5];*/
for (var i = 0; i < camp_names.length; i++) {
chartData_camp.push({
camp_name: camp_names[i],
camp_click: camp_clicks[i]
});
}
AmCharts.ready(function () {
// generate some random data first
// SERIAL CHART
chart = new AmCharts.AmSerialChart();
chart.pathToImages = 'http://www.xxx.com/en/Images/';

chart.dataProvider = chartData_camp;

//cursorSettings.valueBalloonsEnabled = false;
// third value axis (on the left, detached)

// LEGEND
var legend = new AmCharts.AmLegend();
legend.marginLeft = 110;

// WRITE
chart.write('camp_graph');
});
function zoomChart() {
// different zoom methods can be used - zoomToIndexes, zoomToDates, zoomToCategoryValues
chart = new AmCharts.AmSerialChart();
