DPlot

I have data from an Excel Spread Sheet from 10/01/2010 to and including 10/31/2010 . Dplot illustrates the data correctly.
I want it to show intevals as all 31 days instead of the 5 day interval as it defaults.
I change the "Tick Intervals" to "Specify Number" No of tick intervals on the X axis = 31 ...

Sure there is. I found it under "View" Keep Dplot on top.

I use the Zoom Icon from the Menu bar and drag a box around the target.
The first few times the Zoom back is there. And then when I try a few more times it becomes grayed out and I can't return to my original plot

How to change Dplot From always being on top of other windows?

I also noticed that my date range changed, which what is causing the chart offsets.
I can't seem to get the date range to stay withing what I specify in the extents/intervals size.
What to do ?

I noticed when i have zoomed to an area on the graph, the zoom back is not enabled.
So I use control Z to get back to my original image. I then loose my changes.
Another instance is the original chart will so dead (blank area) to the right and left of the original plot. How do I get the image ...

Thanks for the reply. I didnot look close enought at Excel 2007 as it shows up differantly in 2003.
My concern using excel for my data conversion is the 65K limit within excel.
How would I use Dplot to handle the 65K limit in generating the graph?

Do you have examples for writing the plug in in VBA ...

I am evaluating Dplot. Our data is stored in an access database. How do I import my data ?
I have exported the data into excel and then used the Dplot inteface within excel, but I would like to avoid that step if possible.
Also, will the Excel inteface become available for Excel 2007 ?
