Can any one tell me how to use zoom or scroll option with DPlot Jr. I am new to this. my requirement is if i ve data from 1200 hrs to 1500 hrs data, i want to put in view 1200 to 1300 hrs in x-axis initialy and the user can view other data by scrolling it.

You can scroll using the arrow keys but
1) Only *after* zooming in.
2) There's no way to set the zoom window programmatically.

There's no good reason for the first limitation that I can think of, though, and I think this must have been done only because I was being a bit lazy. I've changed this at my end such that the arrow keys work whether the user has zoomed in or not. Will be in the next release.

I'm not sure whether you were asking a question about setting extents or not: if so then take a look at the ManualScale command.

In the next release, yes. The only way to do this right now is to manually zoom in to those extents, then use the arrow keys.

and i can able to see 12 to 15 hrs data in a view also.

On the same plot at the same time? No.
