I have been trying to add a trend line to a discrete (blue pill) field and I can't able to do that. I have tried other ways which is creating a calculated field and using it to the sheet but it is not giving me the visualisation as before. The discrete field contains a yyyy-mm values from the data source which is a string format and currently being used. But I need to add trend line for that using an alternative way. Kindly help!
