使用Plain JS应用不同的主题
在FusionCharts Suite XT中,您可以在相应的JSON / XML文件中为每个图表手动设置外观和功能属性。如果您仅处理少量图表,则可以使用此功能。随着图表数量的增加,您的麻烦也随之增加。FusionCharts Suite随附了预定义的主题,您可以使用这些主题来设置图表的外观或行为。
FusionCharts Suite XT随附以下预定义主题:
fusion (自v3.13.0起)
gammel (自v3.13.0起)
candy (自v3.13.0起)
zune
ocean
carbon
本文重点介绍如何在运行时将不同的主题应用于图表。单击任何单选按钮,以查看图表的外观和样式随每个主题的变化。
配置为更改主题的图表如下所示:

上面示例的完整代码如下:
import FusionCharts from "fusioncharts";import Charts from "fusioncharts/fusioncharts.charts";import FusionTheme from "fusioncharts/themes/fusioncharts.theme.fusion";// Add the chart and theme as dependencyFusionCharts.addDep(Charts);FusionCharts.addDep(FusionTheme);// Create an Instance with chart optionsvar chartInstance = new FusionCharts({

}}); // RenderchartInstance.render();上图通过以下步骤呈现:
1、使用包括必要的库和组件import。例如fusioncharts图书馆等
2、将图表和主题添加为依赖项。
3、将图表配置存储在JSON对象中。在JSON对象中:
将图表类型设置为column2d。
设置图表的宽度和高度(以像素为单位)。
将设置dataFormat为JSON。
将json数据嵌入为的值dataSource。
4、beforeRender调用event将主题从更新fusion为任何其他主题。
5、在中创建了单选按钮,<div>以从中选择主题:
fusion
gammel
candy
zune
ocean
carbon
6、功能已添加到单选按钮,以在运行时更新主题。
