Should be fixed now.
Some libraries I've used were deprecated, so I had to build the complete thing from scratch.
Result:
- value box is always displayed with values, not blanks or other strange stuff
- look and feel are the same as before (whether you like it or not
)
- instead of refreshing the complete page now only the needles are updated. Less load for my server
- sexy animated needles (no nudity, though)
It's HTML5 only, but most recent browsers worth using should support that.
Please test, and in case of problems report back the problem, browser + version and the OS you're using.
PS: the gray color behind the "History" buttons is a known issue, no need to report that.
