该三方开源库从github fork过来,主要将底层接口调用的实现修改成鸿蒙接口的实现,将三方库鸿蒙化,供开发鸿蒙应用的开发者使用

fork地址:https://github.com/blackfizz/EazeGraph

fork版本号/日期:master / 2015/10/5

EazeGraph

EazeGraph是一个用于创建精美图表库。它的主要目标是创建一个轻量级的库,该库易于使用并且高度可定制,具有“最新”外观。

原项目Readme地址:https://github.com/blackfizz/EazeGraph/blob/master/README.md

项目移植状态:支持组件所有基本功能

完成度:100%

调用差异:无

导入方法

har导入

将har包放入lib文件夹并在build.gradle添加

implementation fileTree(dir: 'libs', include: ['*.har'])

Library引用

添加本工程中的模块到任意工程中,在需要使用的模块build.gradle中添加

compile project(path: ':EazeGraphLibrary')

or

allprojects{
    repositories{
        mavenCentral()
    }
}
implementation 'io.openharmony.tpc.thirdlib:EazeGraph:1.0.2'
