ZingChart 如何在 click/select 上修改节点
ZingChart how to modify node upon click/select
我正在使用 ZingChart 制作标准条形图。我选择了各个条形图的状态,但出于一件事。有没有办法显示值框(全局设置为 visible:false)以仅显示所选节点时 clicked/selected?我能够使每个节点的值框显示在我添加的单击事件中,以使用 modifyplot 方法调用外部函数,但我没有看到类似的节点方法,例如 modifynode。如果这不是一个选项,是否有任何方法可以插入一个 "fake" 值框,其标记将在单击事件期间即时创建,并使该元素显示在所选节点上方?下面是我对相关图表的渲染代码。感谢您的宝贵时间!
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);
}
}
});
您最好使用标签而不是值框。我在这里整理了一个演示。
