pChart does not support this directly, last I checked.
However, you can do it with CSS and overlaid elements! One site where you can see an example of this in action is http://craftcult.com/heartchart.php?userid=sugarpinkboutique (press the Get Chart button on the top chart for an example, choose 'seller buyers separate' first for a more elaborate example).
Essentially, you can overlay clickable elements over the chart using JavaScript and/or CSS/HTML. I suggest using absolute positioning in your CSS, and creating the elements with JS based on the data used to create the chart.
I do enjoy working with pChart. It's pretty well-written and flexible. I also saw this link here on SO relating to a library for doing something similar in JS : http://pchart.sunyday.net/ImageMap/

pChart 不直接支持这一点，我上次检查过。
但是，您可以使用 CSS 和重叠元素来做到这一点！您可以在一个网站上看到此示例：http://craftcult.com/heartchart .php?userid=sugarpinkboutique（按顶部图表上的“获取图表”按钮查看示例，首先选择“卖家买家分开”查看更详细的示例）。
本质上，您可以使用 JavaScript 和/或 CSS/HTML 在图表上覆盖可点击元素。我建议在 CSS 中使用绝对定位，并根据用于创建图表的数据使用 JS 创建元素。
我确实喜欢使用 pChart。它写得很好而且很灵活。我还在这里看到了这个链接，与在 JS 中执行类似操作的库相关：http://pchart。 sunyday.net/ImageMap/
