jqPlot饼图工具提示 [英] jqPlot Pie Chart Tooltips

问题描述

我是否正确地认为jqPlot中的Hightlighter类不能处理PieRenderer的工具提示?我花了很长时间尝试使它们工作，但似乎无法显示工具提示.

Am I right in thinking that the Hightlighter class in jqPlot does not handle tooltips for the PieRenderer? I've spent quite a while trying to get them to work however I can't seem to get it to show the tooltip.

如果我是对的，是否可以处理段的翻转并将数据传递给第三方jQuery工具提示?

If I am right, is there a way to handle the rollover of a segment and pass the data to a third party jQuery tooltip?

谢谢.

推荐答案

浏览 jqplot的问题，似乎对此功能有一些要求，但尚未实现.

Looking through the issues for jqplot, it would seem that there have been a few requests for this functionality, but it has not yet been implemented.

基于此问题如何在jqplot饼图上显示工具提示，则可以连接jqplotDataHighlight和jqplotDataUnhighlight事件:

Based on this question How to display tooltips on jqplot pie chart, you could wire up the jqplotDataHighlight and jqplotDataUnhighlight events:

$("#chartId").bind('jqplotDataHighlight', function(ev, seriesIndex, pointIndex, data) {

}); 

$("#chartId").bind('jqplotDataUnhighlight', function(ev, seriesIndex, pointIndex, data) {

});

使用此技术创建自定义工具提示是一个很好的例子，此处.尽管它正在处理气泡图，但它应该为您指明正确的方向.
