May I ask what quality aspect should this system focus on. It should be correct, but what about trade off between system response time and functionality. Like for example, Zooming feature. Should it be like from 1X->2X or should the image magnify gradually. Since pchart will produce static images, some of these issues will be faced while designing.
I would prefer a gradual zoom but haven't made any research about how to implement this. If pChart is not the best tool for this, you can look for a better one. The other day I mentionned pChart because we are currently using it (in phpMyAdmin 3.4) for static charts.
So, is it like we can use any type of zoom but whenever the number of
points in the screen fall below a certain number, we show labels?
Also, I think in pChart its not very straight forward to implement clickable items(click data points to view data row). We would have to use CSS with overlaid items.
OTOH if there is no open tool for a gradual zoom (web), going in increments (say, with buttons) will be fine.
I also have never implemented such but I found something on the net, http://www.cssplay.co.uk/menu/image_magnifier2.html . I'll try to look for something like this.
