I use Yahoo stock charts all the time and I often will change the height of the charts (percentage scale) and also the horizontal time scale, but the charts keep resetting to the default, sometimes immediately after I get the chart looking how I want. I typically look at 2 or 3 days of activity and have it scaled to 10 or 15% and it will suddenly jump back to the default 1 day setting with the amplitude determined by the stock values. It's very frustrating!!! You put in these great features to control time and amplitude, but then your code defeats those very features!!

If you could just change how often it goes back to default it would be great. Make it 15 minutes perhaps, or better yet, a user option (like a button: go to default view) to control the behavior. Thanks!!
