Exponential scale with class()-function?

[#1]

Hello everybody,

Is it possible to use the class() function to set an exponential scale, maybe by manipulating the class_width variable?

Fi.

I have a bunch of responstimes of a calldesk. I want to count the number of calls which was responded to

a) between 0 and 15 minutes

b) between 15 and 60 minutes,

c) between 60 minutes and 4 hours,

d) between 4 and 8 hours,

e) more than 8 hours.

I don't want to set the intervals in the script, since this costs me too much flexibility in the dashboard.

Any suggestions?

Thanks a lot!!

Maybe I can aggregate?

With class by defalut you can use only equal scale (except some tricks for bounds and so on).

Try to make a formula that returns 1..N for your time values then use pick() to assign correspinding text labels.

Or you can program this logic with dozens of ifs.
