I would prefer a gradual zoom but haven't made any research abouthow to
implement this. If pChart is not the best tool for this, you canlook
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?
I think it's more when the user ceases to see big clusters of data points and is able to perceive the distinct points.
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.
Maybe SVG? Vector output would give users faster feedback (no need to generate big bitmaps on the server and send them) and allow for fluent scaling in browser. Recently even IE got native support, with the release of IE 9.
What about JpGraph?
