rename boolean value in a pie chart

thenormalone — Fri, 04 Jun 2021 23:24:20 GMT

I have a boolean field which I get from the search, now when I do a stats count by boolean_field, the pie chart will show boolean_field=true and boolean_field=false.

How do I rename these values to something custom/more meaningful?

Something like

| eval boolean_field = if(boolean_field == "true", "true meaning", "false meaning")

apologies but I should've mentioned that I tried that. After that if I do a stats command on it, the pie chart only shows one of the values

This is how you can illustrate your data and output in a sanitized fashion:

<your search> | top 20 # limit output for illustration | rename <your boolean field name> as boolean_field # rename to generic name

(because the field has only two generic values, no sanitization needed.) After this, you can use the generic field name to illustrate how the two pie charts differ. (Make sure to illustrate your generic test code.

On my side, I generate a generic data set with the following simulator

| makeresults count=50 # this part simulates data | eval boolean_field = if((random() % 5 == 0 OR random() % 3 ==0), "false", "true")

Sample data look like this

_time	boolean_field
2021-06-07 09:34:58	false
2021-06-07 09:34:58	false
2021-06-07 09:34:58	false
2021-06-07 09:34:58	false
2021-06-07 09:34:58	true
2021-06-07 09:34:58	true
2021-06-07 09:34:58	false
2021-06-07 09:34:58	true
2021-06-07 09:34:58	false
2021-06-07 09:34:58	false
2021-06-07 09:34:58	false
2021-06-07 09:34:58	false
2021-06-07 09:34:58	false
2021-06-07 09:34:58	true
2021-06-07 09:34:58	true
2021-06-07 09:34:58	true
2021-06-07 09:34:58	true
2021-06-07 09:34:58	false
2021-06-07 09:34:58	false
...

As expected, a simple piechart will show true and false

But if I rename my values using

| eval boolean_field = if(boolean_field == "true", "foo", "bar")

the piechart shows two values, foo and bar, not a single value. (Unless the input data happen to contain only one of true or false.)

This can be corroborated by examining the "Statistics" tab under the search box.

boolean_field	count
bar	20
foo	30
