Re: [Flashcoders] array problem,loop.plot
Hi Nasim,
You can certainly create an array of 20,000 elements (or two Vectors,
as I did, with a smaller number).
The problem is, I don't think you can display that many points. How
big is your stage? I had mine set to 1024 x 768, which is normally
about as high as you want to go.
You don't need that many points to create a smooth graph, though. Try
using every 10th point, and either lineTo or curveTo.
To do that, in the part that creates the graph, increment by 10:
// Now draw the graph
for (x = 1; x<= len; x+=10)
Did you get my second e-mail, where I wrote the class for you? It uses
lineTo(), which should give you pretty smooth graph with 2,000 points.
My class isn't bug-free, but it is free, and you should be able to
make it do what you want. If not, I'll take another look at it in the
morning (it's after midnight here).
Cordially,
Kerry Thompson

RE: [Flashcoders] array problem,loop.plot
Nasim,
As you already know, pre-calculating all those data points is too much work for
Flash, and it's also way more points than any monitor can show at one time.
Why don't you try calculating only the points you need, only when you need
them? Tell your boss that 'having an array of points' from -1 to 1 is
the wrong solution.
A solution that will work in Flash is to start by deciding how many points you
can reasonably plot (for example 1000), then define the 'zoom' of your graph by
specifying the START and END values, and then plot ONLY 1000 POINTS between
your start and end values.
Zooming in and out just means changing the START and END values. The onscreen
display will remain the same size, but the shape of the plotted line will
change as you zoom in and out.
Also, if you can, you should buy Keith Peter's excellent book "ActionScript 3
Animation - Making Things Move". It deals specifically with the issues you're
experiencing.

Sure. I knew there would be bugs in my code :-)
Actually, you have so many points, you probably don't need to use
curveTo(). lineTo() would probably work for you, and it just takes two
parameters.
Here's a class I wrote that draws something. It's probably not what
you want, but it works, at least. You can take it from here. (I

Gerry and Henrik have the right answer. Your computer monitor isn't
capable of displaying 20 million points, and Flash will hang, as you
have found out.
This is untested e-mail AS3, but I would do it something like this:
var pointX:Vector.; //vectors are much faster than arrays
var pointY:Vector.;
// You have to create the vector in a new code line
pointX = new Vector.();
pointY = new Vector.();
ndx:int = 0;

{
ndx++;
pointX[ndx]=i;
pointY[ndx]=5*Math.sin(20*i);
}
// prepare to draw the graph
graphics.lineStyle(2, 0X00); //set the line to 2 pixels wide, black
graphics.moveTo(pointX[0], pointY[0]); // move to the starting point
len = pointX.length + 1;
// Now draw the graph
for (x = 1; x<= len; x++)
{
graphics.curveTo(pointX[x], pointY[y];
}
There's more you have to do--importing the graphics package, perhaps
putting this all into a class, and so on. There are probably minor
bugs in the code you'll have to fix--this is just off the top of my
head. I think you will be much happier with performance and appearance

Re: [Flashcoders] array problem,loop.plot
Use a reasonable amount of points. Don't draw more points than the graph is wide. Consider using curveTo to get smoother lines. Consider using the bulk drawing to reduce the cost of telling flash each point. One method call vs one per point can make a difference. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Perhaps the problem is simply that you're trying to plot too many points. If
you're stepping from -1 to +1 in increments of 0.001, that's 20 million
points. Plotting 20 million points of a sine function seems a little futile…
I suggest you try a smaller range and bigger increment first, just to see
whether the code's basically working, e.g. go from -100 to +100 in steps of 0.1.
If speed and space are issues, try using two vectors of Numbers, one for the x
values, the other for the y values.

RE: [Flashcoders] array problem,loop.plot
sorry i correct it
hi
In my program create x,y and i should plot it , the number of point are too
much
2*10 ^ 8
i use for to create point depend on it's formula but my for stuck in 1
with step .001
for( var i:Number= -1 ;i<1;i+=.001) { arr[i]=new object() arr[i].x=i
arr[i].y=5*Math.sin(20*i);
functiononlinedraw()
}
then in another function i plot the point oe by one by graphics.lineTo(x,y)
if the distance be more than 1 it will stuck in loop and give me error
more than 15S my program generate x,y and i should plot it one by one but ,
i think flash dont let me plot poin until the loop finished myproblems
1: how can i do up senario is there better way?
2: Is there a way to set delay in for loop , and i make smal for to show
ploted point that user can see on that time and after delay i full remain
on array ?
how can write this dealy?
3: is this write that array can store data until the last index of them
,and the last index of them is last integer number ???

Not the solution, but I notice you try to add .001 to an integer.
So the var i should be a Number?
