- I bought DeltaGraph Profesional for about $100, ed discount.
-
- Together with Excel, I produced paired scatter plots with nth degree
- ploynomial least squares curve fitting and error bars with less than
- an hour of mucking about. Not the greatest software for Windows,
- but for the price?
-
- Another benefit of D-G, it prints the plot, not the plot plus title
- plus labels plus legend, to the size you specify, exactly.
-
- I just used Excel to set up and analyze the data, and then pasted it
- into a "data sheet" in D-G, selected paired columns, chose chart type,
- set the axis scales and endpoints. I chose curvefit from the menu,
- it brings up a dialog box that allows you to use your own equation, if
- desired, set fit parameters and go. The error bars are another menu
- choice that brings up another dialog box thaat lets you choose options
- and parameters, then go. It was rather painless, once I decided to
- use Excel to collect and transform my data instead of learning their
- "data sheet" format. Just copy and paste it in.
-
- D-G was ragged on by PC Mag and others. Doesn't support TT, uses ATM.
- Data sheets don't work the same as Excel. Menus don't always follow
- Windows conventions. I think the OLE implimentation is buggy and
- switched to just copy and paste. But I based my decision on price.
- I compared the ease of use to MathCad 3.1's advanced math pack curve
- fitting template, same accuracy and precision on the coefficients, but
- D-G blows Mathcad away in presentation graphics on the curve fit alone.
- But viewing the coefficients and storing them required a copy from thier
- box to a notepad, then a little editting. It can't paste its own coefs
- to its own data sheet! (without editing)
-
- Hope this helps the poor folk like me out there.
