  • 0

I have large amount of data to be plotted on iPad using a core plot. The data is in a CSV file format. Currently I’m parsing the data and plotting it real time. The problem is i’m trying to read the file and store in an array inside the program and at the same time plot it. So there is no data inconsistency. The graph keeps going on and off. For a file size of 60k to 100k lines is good to use core data. Because the data is transferred live with a delay of 8 seconds or so. Will there be any issues?

    You’re not going to get real time performance with 100k data points, especially on iOS. The device doesn’t have enough pixels to display that many distinct points anyway. The flickering might be from the plot taking too long to draw and things getting out of sync.

    You need to filter the data or only plot a subset, for example, only the first 500 points.
