Class is not JSON Serializable

[keithii]

In creating an example similar to the multi-line chart at the end of the Readme, the settings in class option need to be moved to class pluginOptions to work with updates to chart.js. However, an error occurs that the classes (e.g., class Title) are not serializable.

The correction seems to be the need to add 'General' as the second argument of ChartUtils.cleanClass on line 72 of pychartjs.py under 'def getPluginOptions'

Which version of chart.js are you using? I'll admit I haven't checked the compatibility in a while.

I meant to go back in and update my note. It looks like the interface changed for v3.

Weird, I last tested it for 3.9.1 and I'm pretty sure it worked fine then. I'll have another look, I might not have checked the multiline :)

I appreciate that. When I look at the return for your example, there is an error for yScales. I didn’t try for very long to fix that. The only thing I really messed with was the title, which I had to move to PluginOptions, then make that change to the getPluginOptions and add General to the method call. The legend is also still sitting above even though the position says bottom.

Looks like to fix the legend location, "Bottom" needs to be "bottom" and the error being received back from chart.js regarding invalid scale configuration was due to the [] around _yScales.
