Calculation of pearson-correlation with Grafana/InfluxDB
Calculation isn´t working, no error message. Only “No data” despite there is data in the time range.
Calculation of the pearson-correlation with the cov() function and print it on the Grafana Dashboard as Single Stat.
Also tried pearsonr() function or grouping the tables, but nothing worked for me.
Show correlation between two variables on the Grafana Dashboard.
