Hello everyone:
I am a new Mathematica user and have been teaching myself the program
using real-world examples and reverse-engineering the code. This
approach has worked well for the last few months since I began, but I
have run into a roadblock and was hoping someone will help me out.
I am currently trying to import financial data and generate a
histogram of the daily volume for a given security. Ultimately I am
going to make this into a sparkline (very useful in my work). Use of
the options to create the sparkline is clear. Where I am getting stuck
is the importing and formatting of the data. I think setting up the
iterators is my problem, but I have tried about every option and have
not found the answer yet.
I have been using the default examples in the online documentation of
IBM and March 1, 2004. Here are a few of the approaches I have tried:
Histogram[Table[FinancialData["IBM","Volume"],{"March 1,2004"}]]
Histogram[Table[FinancialData["IBM","Volume",i],{i,"March 1,2004"}]]
Histogram[Table[FinancialData["IBM","Volume",i],{i,"March
1,2004","March 20,2009"}]]
Any suggestions,
Thanks,
Jon
