    <p>I've installed Enthought's EPD (64 bit for Windows 7).</p> <p>I'm trying to plot historical stock quote data using Yahoo's API. All the code I'm trying to use is on this blog post: <a href="http://www.traineetrader.com/importing-stock-data-from-yahoo-using-python/" rel="noreferrer">http://www.traineetrader.com/importing-stock-data-from-yahoo-using-python/</a></p> <p>The ystockquote.py file works fine.</p> <p>But the second script to plot Google's historical stock quote doesn't work for me. This is the code (from the website):</p> <pre><code>import ystockquote # Get Quotes 01/01/2006 - 01/01/2009 GOOG = ystockquote.get_historical_prices('GOOG', '20060101', '20090101') # Create empty lists, quick and dirty GOOGOpen = [ ] GOOGClose = [ ] GOOGDate = [ ] GOOGHigh = [ ] GOOGLow = [ ] GOOGAdj = [ ] GOOGVolume = [ ] # Populate lists from downloaded data for i in range(1, 755): GOOGDate.append(GOOG[i][0]) GOOGOpen.append(GOOG[i][1]) GOOGHigh.append(GOOG[i][2]) GOOGLow.append(GOOG[i][3]) GOOGClose.append(GOOG[i][4]) GOOGVolume.append(GOOG[i][5]) GOOGAdj.append(GOOG[i][6]) plot(GOOGAdj) title("Google Adjusted Close") ylabel(r"GOOG Closing Price ($USD)", fontsize = 12) xlabel(r"Date", fontsize = 12) grid(True) </code></pre> <p>I get the following error:</p> <pre><code>NameError: name 'plot' is not defined </code></pre> <p>Any tips on what I'm doing wrong? Or how to get this to run? If I include "from pylab import *" at the top of the code, I don't get the error, but nothing happens.</p>

    2. CON.B. If you start `ipython --pylab`, it loads the pylab stuff automatically, and also uses some tricks so the console doesn't block when plot windows are open.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
