Functions as a variable

DSDD — Sat, 16 Nov 2024 00:58:57 GMT

Dear community,

i want to let the user choose between average and median in buttons.

So, is it possible to take the Avg and Median function in a variable, let say v_fun?

And how to evaluate functions within the variable on my dimension, let say body_weight? (How does the syntax look like?)

Thanks

Create a variable and assign the value like below

variable name: v_fun

value: Avg($1)

In chart, ur dimension and expression is like

$(v_fun(body_weight))

-- gives average of body_weight based on ur dimension

Thanks for your answer. It works.

What does $1 achieve in this context, especially when $(v_fun(body_weight)) is evaluated?

$1 here is works like parameter, you can pass any field name.
