plots do not display if sector and/or investment type selectors are changed before clicking "Go!" button #168
Description
e.g. load the site, go to the "Sector-level Analysis" tab, change the sector selector to "Automobile", click the "Go!" button. One plot doesn't show anything, one plot shows an error message, and one plot displays but seems to not have any relevant data.
If you then change the sector selector to "Power", and then change it back to "Automotive", the plots work as expected.
