Bar chart with multiple series

[pitmod]

Hello,

I have the following data

book="title1" reader="reader1"
book="title1" reader="reader1"
book="title1" reader="reader2"
book="title1" reader="reader2"
book="title2" reader="reader1"
book="title2" reader="reader3"
book="title2" reader="reader3"
book="title2" reader="reader3"
...

I'd like to represent it in a multi-series bar chart showing number of reads by reader per title as in a drawing below:

count
^
|   _____________     _____________
|   |                                |     |                                 |
|   |_reader1_____|     |                                 |
|   |                                |     |_reader3_____ |
|   |_reader2_____|     |_reader1_____ |
----------------------------------------------------> titles
         title1                                   title 2

title1,reader1
title1,reader2
title1,reader2
title2,reader1
title2,reader3
title2,reader3
title2,reader3"
| multikv forceheader=1
| stats count  by book,reader
| chart values(count) as count over book by reader

• use column chart
• under format in general set "stacked" to stack mode

Note: stacked is middle option of stack mode.

Hi @pitmod ,

Should work with this simple SPL:

|  chart count by book, reader
