我使用ZingChart作为标准条形图。对于个别酒吧我选择的状态是按照我的意愿工作但是一件事。有没有办法显示值框(设置为visible:false全局),以便在单击/选择时显示所选节点?我能够使用modifyplot方法在我添加的单击事件中显示每个节点的值框以调用外部函数,但是我没有看到类似modifynode等节点的方法。如果这不是一个选项,是否有任何方法可以插入一个“假”值框,其标记将在click事件期间动态创建并且该元素显示在所选节点上方?下面是我所讨论的图表的渲染代码。谢谢你的时间!
zingchart.render({
id: "vsSelfChartDiv",
width: '100%',
height: '100%',
output: 'svg',
data: myChartVsSelf,
events:{
node_click:function(p){
zingchart.exec('vsSelfChartDiv', 'modifyplot', {
graphid : 0,
plotindex : p.plotindex,
nodeindex : p.nodeindex,
data : {
"value-box":{
"visible":true
}
}
});
var indexThis = p.nodeindex;
var indexDateVal = $('#vsSelfChartDiv-graph-id0-scale_x-item_'+indexThis).find('tspan').html();
updateTop(indexDateVal);
}
}
});

使用标签而不是价值框可能会更好。我在这里放了一个演示。
我在ZingChart团队。如果您有任何其他问题,请随时与我联系。
// Set up your data
var myChart = {
"type":"line",
"title":{
"text":"Average Metric"
},
// The label below will be your 'value-box'
"labels":[
{
// This id allows you to access it via the API
"id":"label1",
"text":"",
// The hook describes where it attaches
"hook":"node:plot=0;index=2",
"border-width":1,
"background-color":"white",
"callout":1,
"offset-y":"-30%",
// Hide it to start
"visible":false,
"font-size":"14px",
"padding":"5px"
}
],
// Tooltips are turned off so we don't have
// hover info boxes and click info boxes
"tooltip":{
"visible":false
},
"series":[
{
"values":[69,68,54,48,70,74,98,70,72,68,49,69]
}
]
};
// Render the chart
zingchart.render({
id:"myChart",
data:myChart
});
// Bind your events
// Shows label and sets it to the plotindex and nodeindex
// of the clicked node
zingchart.bind("myChart","node_click",function(p){
zingchart.exec("myChart","updateobject", {
"type":"label",
"data":{
"id":"label1",
"text":p.value,
"hook":"node:plot="+p.plotindex+";index="+p.nodeindex,
"visible":true
}
});
});
// Hides callout label when click is not on a node
zingchart.bind("myChart","click",function(p){
if (p.target != 'node') {
zingchart.exec("myChart","updateobject", {
"type":"label",
"data":{
"id":"label1",
"visible":false
}
});
}
