How can I graph a series of scores? - actionscript-3

Question

I am trying to make a score graph. I have last seven scores of the game. I could use the graphics.lineTo function but it takes so long.
Is there an easy way to do this ?
Example graph.
Here is what I tried so far. I made 20-40-60-80 lines movieclip and duplicate and change their name of each level.
if(score1 == 40 && score2 == 20 && makeline == true){
line20.x = 184;
line20.y = 411;
yirmiasah2 = true;//yirmi asa
}
if(score1 == 40 && score2 == 40 && makeline == true){
line40.x = 184;
line40.y = 411;
}
if(score1 == 40 && score2 == 60 && makeline == true){
line60.x = 183;
line60.y = 366;
}
if(score1 == 40 && score2 == 80 && makeline == true){
line80.x = 172;
line80.y = 384;
}

The question is not clear but you can try something like this.
Somewhere in your code you undoubtedly have a variable holding the score of the current game. You haven't shown that, so I'll call that current score from the last game currentScore of type int. First this variable is declared outside of any functions.
var currentScore:int;
Then, while the game is being played, this value goes up whenever the player earns a point. In my example, he gets a point when Sprite A touches Sprite B
if (spriteA.hitTestObject(spriteB)){
newScore++; // adds one to the newScore variable
}
Make an array to hold your scores in. Put this outside of any functions. Putting it at the same place you put the currentScore variable makes sense.
var scoreArray:Array = new Array();
As each score is made final (at the end of a game), add that score to the array:
if (gameOver == true){
// make a new variable to add to the array and give it the same value as the score of the last game
var newScore:int = currentScore;
// add the new variable to the array
scoreArray.push(newScore);
// this adds the newScore variable to the array.
// after 7 games, you'll have 7 values in the array.
}
Then to draw the graph:
var scoreGraph:Sprite = new Sprite();
addChild(scoreGraph);
scoreGraph.graphics.moveTo(0,100);
scoreGraph.graphics.lineStyle(1);
for (var i:int = 0; i < scoreArray.length; i++){
scoreGraph.graphics.lineTo(i*10,100-scoreArray[i]);
// this will space out along the x axis by 10 pixels and put the x axis at 100 pixels down.
}
