date and time scaling

[Mithil]

Hi all ,
I want to create a chart which has date and time in the
x-axis and the scaling of the dates should be set in such a way that
there is difference in scale for each minute. And the data of the last
28 days are to be plotted so this will be a huge data set if i plot the
date with all the minutes in it so could some one plz help me out.

Regards,
Mithil

it should plot it by default if your dataset contains these items; you
shouldn't have to do anything special. what problems are you having?

The problem is I don't have it in the data set i have only few date and
time with corresponding data to it. For example i have data :

Date & time: 1/6/2006 12:00, 1/6/2006 13:00, 1/6/2006 15:00
Data: 1 , 2 ,
3

then it would mark it just like that it wouldn't show 1/6/2006 14:00 as
zero in this case i have shown it by hours and in my real data set i
have to show it by minutes so there will be a lot of data involved (abt
200,000) in it plz help me out i am really stuck in this situation.

you need to think of a redesign, a user cannot follow that amount of data
points, and rendering such a large quantity of points, even if it could be
done, would kill the end-users processor. That said, the OWC has no upper
limit on the number of data points in a chart; doesn't mean that you have to
use a quarter million either!
