Points Shifting on SetScrollView

[User (Legacy)]

I have a chart with 144 data points  (every 10 minutes).  I allow the user

to zoom in, at which point I want to show 3 hours.  If i zoom in , and

scroll to the beginning of the day/chart, and modify values (say at 8:10 and

8:20), then, as soon as i scroll away (using setscrollview) the values get

shifted by 1 datapoint and become 8:20 and 8:30.  Only if i scroll back to

the chart beginning (far left) does it correct itself.

I am using SetScrollView( pos, pos+18) to get to a particular dataset.

any ideas?

thanx,

Ok, as you probably  hoped... in creating a test case to send, i was able to

fix the problem.

I found that if you have  AXIS_X.STEP > 1   (i have it at 6), and

SetScrollView(1,20), it shows points 0 thru point 19, but if I have STEP =

1, it shows points 1 through point 20.  So, to fix it, I set STEP = 1 and

SetScrollView( 1,19 ).

thanx for your quick and willing support,

dev

Yes the scroll is rounded to the step, actually it is rounded to the

MinorStep (this is the scroll increment) so if you want to set the step to

something else, set the MinorStep to one so that you can scroll one-by-one.
