I created a chart with too many columns, like following:
source="/abc/def/aaa.log | chart count(eval(searchmatch("12345"))) AS "The First Column", count(eval(searchmatch("23456"))) AS "The Second Column",....., count(eval(searchmatch("22222"))) AS "The twenty first Column"
Is it possible to break this chart to several small charts but showing within same report?
Try the trellis option, in your dashboard visualization where you have selected chart option, there you can see more options click on that for Trellis and see if that works for you
