推荐答案

通常，样式表的首选方式是不使用代码，而是按照jschoen的建议仅使用css样式表.此外，如果需要进一步的自定义，则可以使用代码中的css查找来挖掘从序列数据生成的节点，并应用各种其他css样式.

In general the way preferred way to style charts is without code, using only css stylesheets as jschoen recommends. Additionally, if further customization is required, you can use css lookups from code to dig into the the nodes generated from series data and apply various additional css styling.

以下是有关动态更改示例程序，以给出答案.在示例应用程序中，所有其他CSS样式都是通过代码中的setStyle调用完成的.使用类似的查找技术，您可以访问系列节点以应用适当的样式表样式类，而不是setStyle调用.

Here is information about dynamically changing a JavaFX line chart style and a sample program to go with the answer. In the sample app, all of the additional css styling is done via a setStyle call from code. Using a similar lookup technique, you could get access to the series nodes to apply an appropriate stylesheet styleclass rather than a setStyle call.
