Adding points to Charts dynamically will eat up all memory?

[Egn1n3]

Hi all,

I am adding points to the spline chart using the append method like this:

series1.append(xindex, message);
xindex++;

I also update the x-axis accordingly so the spline chart "scrolls" from right to left:

if(xindex > axisX.max){
axisX.min++;
axisX.max++;
}

My question: by keep appending points to the spline graph I would assume you run out of memory at some time?
I can remove the first point when I hit the max on the X-axis but still my xindex counter would go up indefinitely:

if (xindex > axisX.max) {
series1.remove(0);
}

Any thoughts about his? Is there a better way?

Thanks.

Have a look at this post:

It shows how you can implement a "moving" graph.
