Graph and Chart Study

1.选择主题 “Themes”，以"Graph"——“preset7” 为例；

2.选择“Canvas”——“GraphChart”预制体，1.Set data categories  即“设置数据类型”，each category has it's own visual settings 每个类别都有自己的视觉设置，Line Thickness等‘

3.Now lets feed the chart with data _现在让我们用数据填充图表;   Use category names from the inspector（使用检查器中的类别名称）

4.Drag the chart in to  the script property（将图表拖到script属性中）

　　

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using ChartAndGraph;

 public class MyGraphSample : MonoBehaviour
 {
     public GraphChart chart;

     private float Timer = 1f;

     private float X = 10f;
     // Start is called before the first frame update
     void Start()
     {
         //It is also best practice to enclose graph changes in StartBatch and EndBatch calls

         chart.DataSource.StartBatch();

         //It is best practice to clear a category before filing it with new data
         chart.DataSource.ClearCategory("KOKO");
         chart.DataSource.AddPointToCategory("KOKO",,);
         chart.DataSource.AddPointToCategory("KOKO", , );
         chart.DataSource.AddPointToCategory("KOKO",,);
         chart.DataSource.AddPointToCategory("KOKO", , );

         ////now we do the same for the second category
         //chart.DataSource.ClearCategory("Juhnko");
         //chart.DataSource.AddPointToCategory("KOKO", 0, 0);
         //chart.DataSource.AddPointToCategory("KOKO", 5, 5);
         //chart.DataSource.AddPointToCategory("KOKO", 8, 7);
         //chart.DataSource.AddPointToCategory("KOKO", 15, 10);

         //now we do the same for the three category
         chart.DataSource.ClearCategory("liang");
         chart.DataSource.AddPointToCategory("liang", , );
         chart.DataSource.AddPointToCategory("liang", , );
         chart.DataSource.AddPointToCategory("liang", , );
         chart.DataSource.AddPointToCategory("liang", , );

         //each startBatch call must be matched with an EndBath call !!!
         chart.DataSource.EndBatch();

         //graph is redrawn after EndBath is called
     }
     //lets handle a click event
     public void OnItemClick(GraphChartBase.GraphEventArgs args)
     {
         Debug.Log("点击的类型是："+args.Category+" 索引点为："+args.Index);
     }

     // Update is called once per frame
     void Update()
     {
         //now let's add a streaming data update the goes every 1 second.
         Timer -= Time.deltaTime;
         if (Timer<=0f)
         {
             Timer = 1f;
             chart.DataSource.AddPointToCategory("KOKO",X, Random.value);
             chart.DataSource.AddPointToCategory("liang", X, Random.value);
             X++;
         }
     }
 }
