Adding points to Charts dynamically will eat up all memory?
-
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:
https://forum.qt.io/topic/93398/sliding-grid-for-chart
It shows how you can implement a "moving" graph.
