stocQt example shows bogus data for some stocks

Some stocks in the list are listed with NaN as their share-price and movement; presumably data for these is no longer available, so this is fair enough. [Examples: DTV, CTRX, ALTR, KRFT, LINTA.]
However, if I click on one, I do get shown a graph of stock price movement, that presents itself as being for the stock in question. It is in fact whatever stock price graph I most recently looked at - and doesn't change when I click on Max, Year, Month or Week to change scale, although the graph's time axis does update its label.

The example should show an "I got nothing" display rather than (entirely without hint that this is so) pretending to have data for the given stock.
