You can try this tool by beaker007 https://peakd.com/hive-13323/@beaker007/splinterlands-statistics-v0110-add-land-monitoring,, I am collecting data from this tool. I also used some few other tools like splinterstats for knowing exact Rental spend, https://www.splintercards.com for reward card monitor and splex for seasonal reward cards earned. other than those I used canva for making chart. It will be easy once you start doing it.
