I have two columns with date/time data. One column represents the day with a date and the other represents the time I had my first coffee for the day.
I would like to create a chart out of this so I can easily visualize the trend but I can't find the option to do this. When I select both columns and try to create a chart all options are blacked out.
I did find a workaround by not using a time format for the 'first coffee' data but using integers like
1030 instead of
10:30. While this technically works it doesn't look as nice since it will interpolate axis values like 1080 which do not make sense for the mod 60 set of time.
Does anyone know if this is possible and if so, how?
This is example of my data set:
