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",0,0);
        chart.DataSource.AddPointToCategory("KOKO", 1, 1);
        chart.DataSource.AddPointToCategory("KOKO",2,3);
        chart.DataSource.AddPointToCategory("KOKO", 5, 8);

        ////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", 0, 0);
        chart.DataSource.AddPointToCategory("liang", 3, 3);
        chart.DataSource.AddPointToCategory("liang", 5, 7);
        chart.DataSource.AddPointToCategory("liang", 7, 11);


        //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++;
        }
    }
}
