GraphView_openharmony

折线图/圆点图/柱状图

安装说明

Method 1:For using Graphview module in sample app ,add the below dependency to generate hap/har,Modify entry/build.gradle as below:

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar','*.har'])
testCompile'junit:junit:4.12'
implementation project(':graphveiw')
}

Method 2:For using Graphview in separate application using har file ，generate .har package through library and add the har file to the entry/libs folder.Modify entry/build.gradle as below:

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

Method 3:For using Graphview in separate application using maven dependency,modify entry/build.gradle as below:

 dependencies {
    implementation 'io.openharmony.tpc.thirdlib:graphView-library:1.0.3'
 }

使用说明

一.GraphView 介绍

   <com.jjoe64.graphview.GraphView
     ohos:id="$+id:graphView"
     ohos:height="200vp"
     ohos:width="match_parent"/>

    GraphView graph = (GraphView) findComponentById(ResourceTable.Id_graphView);
     LineGraphSeries<DataPoint> series = new LineGraphSeries<DataPoint>(new DataPoint[] {
          new DataPoint(0, 1),
          new DataPoint(1, 5),
          new DataPoint(2, 3),
          new DataPoint(3, 2),
          new DataPoint(4, 6)
     });
     graph.addSeries(series);

二.GraphViewXML 自定义介绍

    <com.jjoe64.graphview.helper.GraphViewXML
     ohos:id="$+id:graphViewXml"
     ohos:height="200vp"
     ohos:width="match_parent"
     ohos:seriesData="0=5;1=0;2=4;3=2"
     ohos:seriesType="points"
     ohos:seriesTitle="test5"
     ohos:seriesColor="#1E90FF"
     ohos:title ="test1"

说明

本库目前只支持静态数据图形展示 不支持滑动/缩放以及如下相关 API

1.StaticLabelsFormatter staticLabelsFormatter = new StaticLabelsFormatter(graphView_01,new String[] {"old", "new"},new String[] {"high", "low"}); 此 API 问题为原三方库遗留问题，当静态标签格式化程序传递 2 个不同的垂直标签时，它显示两次第一个标签，而不是显示两个集合标签。，由于代码复杂性和功能耦合性暂无法找到解决办法
2.public class GraphView 内 takeSnapshotAndShare 此 API 与项目功能实现无关是一个分享功能， 因此考虑其价值与困难程度暂不考虑实现此功能
2.public class LineGraphSeries 内 public void setDrawAsPath API（AccelerateInterpolator）缺失并且未找到替代方案导致此类相关功能无法实现 3.public class LineGraphSeries 内 public void setAnimated(boolean animated) API（AccelerateInterpolator）缺失并且未找到替代方案导致此类相关功能无法实现 4.public class BarGraphSeries 内 public void setAnimated(boolean animated) API（AccelerateInterpolator）缺失并且未找到替代方案导致此类相关功能无法实现 5.public class Viewport 内 OverScroller / onScroll 涉及到缺失 API（AccelerateInterpolator）API 缺失并且未找到替代方案导致此类相关功能无法实现 6.public class LineGraphSeries 内 AccelerateInterpolator API 缺失并且未找到替代方案导致此类相关功能无法实现
7.如果 2 个图形系列具有相同的系列标题，具有不同的系列颜色，则图例中仅显示第一个系列信息
