I am trying to make a chart that will continuously shift the data to the left and add on new data on the right. It's a pretty simple design, 6 chart lines, 250 data points each. I have it working, but each refresh of data takes over a second to accomplish and uses 100% of the CPU. It specifically on the updateItemAtIndex call (or the replaceItemAtIndex).
Does anyone know a way to do these efficiently?
Thanks,
Jon
