Thanks Shashi, Our application displays medical ultrasound video clips (30-60Hz) clips, where a clip is typically a second long and thus some 30-60 video frames. A line chart is rendered next to the video. The chart renders time versus versus various medical measurments that have been made in the video image frames. So there are 30-60 x Axis points, and around a half dozen measurement curves (y data curves). So as the video plays, a vertical indicator line (stripline) should move in sycnroncity along the x axis, giving the user an temporal indication in the chart of the relative location of the currently displayed video frame in the clip.
Again, everything works fine, but the CPU usage is higher than we can accommodate, e.g. much higher than a line drawn in HTML canvas.
This is a lot to explain, let me know if that is not clear, I can send a screenshot or show a video if that helps. regards, Robert
OK here is my example:

Thanks Shashi, I will put together a JSFiddle and let you know when it is ready.
Thank you!
