Hello, you don’t need to suspend updates, but it helps in some scenarios.
For instance, if you have 3 dataseries all Appending, and you call SuspendUpdates on one, it will freeze the parent chart and you will only get one redraw.
We use this technique to throttle re-drawing when appending lots of data.
You are right to Append using array though: this method is about 10x faster than appending point by point.
