Steve: a quick note, to thank you for helping usher Steel Gauges into WeatherCat's bag of tricks. Installation and live implementation was quick and easy, thanks to very clean instructions on the wiki page, and especially clear code.
Following configuration directions on the wiki, I placed all the files at top level of my website. Next, edited gauges.js in the scripts sub-folder, including line 19, replacing imgPathURL with imgPathURL : '/',
.
However, the website gauges did not respond as expected - e.g., when I would "mouse-over" any of the gauges,
the resulting popup graph was blank - showing a small "?" to indicate a missing image. The imgPathURL value seemed incorrect.
.
So I ftp'd the locally-generated graphics to the web site into the images sub-directory, and changed gauges.js back to original value of imgPathURL : './images/',
Now the web site worked as expected, with popup strip chart graphics.
.
Satisfied with the above results, I tried the following edit to line 19 in gauges.js:
imgPathURL : './/', //*** Change this to the relative path for your 'Trend' graph images
and, now things are working to my satisfaction - the images are being updated routinely by FTP to the top level of the web server.
for whatever it's worth, my current WeatherCat / steel series gauges server is hosted by Charter's user web pages sites - webpages.charter.net
just prior to the release of Steel Series Gauges, I was using Dropbox to host the site, in my /Public sub-directory.
I don't have any experience with webpages.charter.net - and can't explain the discrepancy in the '/' and './/', but thought it might shed some light for other users trying to get their mouse-over strip chart graphics to work as expected.
again, the information above reflects only my recent experience with the gauges. I am very pleased with the results, and especially impressed with this forum, its moderation, and the user input. It's quite obvious that the members are very community-minded. What a great service to those just getting started.
