Html 5 column chart: show sum of all values in title

[detlef.brendle]

Hi,

i want to render a column chart with one series.

On x-axis I have dates, on y-axis integers.

 

My question is if it is possible with some built in function to show the sum of all values.

 

Assume I have:

2016-01-01:  200

2016-01-02:  100

2016-01-03:  14

 

I want to show in my title "104.66 average". (200+100+14)/3

 

How can this be achieved ?

 

Thanks,
Detlef

I was able to do so by using the functions and assign it to a variable.
