Financial data has lots of features, but I don't see a way yo get this sort of thing. In mineralogy and crystallography, one would like to display the morphology of a crystal based on the knowledge of its symmetries. I had hoped Wolfram Alpha might make this sort thing easy, but I haven't had any success.įinancialData would seem natural for this sort of thing, but I don't see anyway to do it. Mathematica (disambiguation) Mathematica is a computer algebra system. Even better if I could access the data directly from the sites. It looks like I need to navigate to the pages, send some data to select specific files and formats, trigger the download, then access the downloaded data from my own machine. The simplest way to import data is to call importExcel.
I've looked at the documentation on Importing but I find scant documentation (actually none) on how to go about something like this. DataTricks is a simple Mathematica package for extracting data from Excel workbooks. I'd like to import these kinds of price or rate data streams (accessible as CSV or Excel files at the above URLs) directly into Mathematica. So why does it look like an ellipse The reason is that Mathematica' s plotting program assumes that the ratio of width to height is equal to 1/the golden ratio.
I tend to have an interest in the daily data (see the above settings on the URLS) you conclude either I or Mathematica have messed up, look carefully at this curve this curve goes through the points (1, 0), (0, 1), (-1, 0) and (0, -1), just as a circle does. The data sets get updated, some as often as daily. Louis Federal Reserve Bank has a great set of data available on a variety of their web pages, such as:
