Math functions

It's possible to compute math values like standard deviation using the chart data and itegrate the value into the chart with annotateLabel or inGraphDataTmpl.

Integrated math functions

• mean
• varianz
• stddev (Standard deviation)
• cv (Coefficient of variation)

If you want to add the difference between the current value and the mean you can use:
`inGraphDataTmpl: '<%=meanDif()%>'`
If you want to have the varianz over each data point:
`inGraphDataTmpl: '<%=varianz()%>'`
And it's possible to round the data using `inGraphDataTmpl: '<%=varianz(3)%>'`
The default number of decimal places are `2` `inGraphDataTmpl: '<%=varianz(2)%>'` = `inGraphDataTmpl: '<%=varianz()%>'`
