Computing with Data from Wolfram|Alpha
The Documentation Center has information about how to turn a Wolfram|Alpha query into computable data. You can quickly access and program with this data.
To access the computable data from Wolfram|Alpha, use the WolframAlpha function. The following example asks for the recent price of Microsoft’s stock in 2007:
We can access the data that Wolfram|Alpha uses to make the plot. Click the plus button above the top-right corner of the chart. This opens a menu where you can select other ways to view this data.
Select “Computable data.” “Computable data” creates a new WolframAlpha expression that asks for the data in a computable form instead of a plot.
This expression gives the chart’s data in a computable format. You can analyze this data like any other set of data.
