HI All,
Is there any way to draw a 2d graph of ECG (in wave form) in iphone .I am getting a large anount of data in couple of seconds i mean the gap will be of just 1 Secs.then is there any way to draw the graph in iphone or any library (IN c or c++) by which i can use it and it draw a live graph of any heart beat analysis and looks alike a live video.
Thanks Balraj.
Apple's Accelerometer example app (available on their iOS developer site, and with full source code) shows how to draw a 2D graph animated several times a second.
In addition to the Accelerometer sample that hotpaw2 points to, which is reasonably performant when it comes to graphing realtime data, there is the Core Plot graphing framework. Core Plot can give you a drop-in component with more options when it comes to formatting your graphs, but it may not be the fastest for displaying many data points that change rapidly on the iPhone.
