Since there are lots of smrt people lurking on this site, I figure I can get some good leads.
I am now doing some data analysis (geochem) on Windows computers, and I need a good software package to do my job as efficiently as possible.
In particular, I have data in Excel (and some in MS Access) and I'd like to generate some histograms. I'd also like to be able to fit the resulting histograms with any user-defined function that I choose. I would also like to have the resulting graphic suitable for presentation in a report.
I have tried some packages, but so far have had no luck. I'm trying to balance usability and cost. The price isn't the most important factor. I'd shell out if I get some value. Some of my findings so far:
Straight-up Excel: Ugh. The histogram option gives a bar chart. The automatic binning just gives intervals of |max-min|/nbins.
XLStat: An add-on to Excel. I've downloaded the trial version, and now a window pops up when I start Excel, and also when I close Excel. Also, when I double click on a file in windows explorer now, XLstat somehow interferes, and I get a blank worksheet. When I finally get the data up, the histograms come out half decent. For fitting, a list of about 20 functions are available. Not sure if I can fit a user-defined function. price: over $400USD.
Kaleidagraph: Opens up an Excel file fine. Makes a nice looking histogram. However, when one wants to change the scale of the x-axis, or fit a function to the distribution, I'm told by the company's support that I have to create an x-y graph, choose a bar chart option, and then widen out the bars, etc, etc. So much for efficiency. Price: about $200USD.
Originpro 8: I just got the trial version. the learning curve seems a little steeper for this one. I get a nice histogram. Haven't figured out how to fit it yet. Is it worth the price: about $1000USD?
Surely there is a good program out there. Any and all comments are appreciated.
If there is a Linux-based program - feel free to suggest that, too.
