jQWidgets jqxChart enableCrosshairs属性用法及代码示例

jQWidgets 是一个 JavaScript 框架,用于为 PC 和移动设备制作基于 Web 的应用程序。它是一个非常强大和优化的框架,独立于平台,并且被广泛支持。 jqxChart 是一个轻量级且函数强大的图表小部件,100% 用 javascript 编写。它提供了许多高级函数并支持三种不同的渲染技术——SVG、HTML5 Canvas 和 VML。

enableCrosshairs 属性用于设置或返回 enableCrosshairs 属性。即此属性用于启用或禁用十字准线的线条。它接受布尔类型值,其默认值为 false。
