I wanted to create a three dimensional time series in ODV (say Time on X, Depth on Y and temperature on Z). When I entered the data to ODV using a template similar to this one I realized that although I have date and time of sampling on the spreadsheet, and although ODV reads those fields and they can be used for selecting samples, when I try to set them as axis values the date can't be selected.
After some reading on the ODV user manual, I found out what I need to do in order to use dates for axis is:
- One field (column) left of the bottom depth field I add a field named "time_ISO8601"
- The value in this field is the sum of the date and time fields
- The field formatting is date format as perscribed in ISO8601 (yyy-mm-ddThh:mm:ss)
Ever since this revelation, I have a new template I use and you can download it here
For those (like me) who like screencasts, here is the process:
