meterGaugeRenderer draws but throws exception if it is NOT the first JQPlot element rendered on page.

[ABPTech]

Have tried updating to latest version, no difference. I have a page that uses multiple JQPlot graphs to display information about a piece of hardware such as CPU or RAM usage as well as historic graphs showing those data points over time. If the meter gauge is the first one listed on the page, it works just fine and the console shows no errors. If any other type of graph is placed inline before the meter gauge, the meter renders, but then throws the following exception and breaks all subsequent JSPlot graphs from being rendered (and kills all javascript functionality).

As you can see in the screenshot, the MOS Score historic line chart works just fine, the meter gauge is rendered (with the % number curiously in the top left), and then the CONCURRENT CALLS graph is broken (not rendered).

Here is the Javascript that generates these 3 graphs:
