A dynamic graph based on an editable table


In this chapter, we are going to combine a few of the previous recipes and make a graph editable by showing a table to the user in which he can change the values at will.

We'll use the infrastructure that was created in the Sending data updates to the graph recipe in this chapter, to send new data to the graph.

Getting ready

This recipe starts from virtually the same class, only now we've freed up some screen space underneath the graph where we will put the editable table:

package com.graphing.dynamictable
{
    import flash.display.Sprite;
    import com.graphing.PointGraph;
    public class Recipe5 extends Sprite
    {
        private var _graph:PointGraph;
        private var _data:Array = [[0, 20], [50, 70], [100, 0], [150, 150], [200, 300], [250, 200], [300, 400], [350, 20], [400, 60], [450, 250], [500, 90], [550, 400], [600, 500], [650, 450], [700, 320]];

        public function Recipe5() 
        {
            _graph = new PointGraph();
