I have a cell with 4 columns in which the first one is a day, the second is a month, the third is a year and the fourth is an index value. I would like to know if there's a way of plotting a "timelapse" on the x-axis using the info in the first three columns and the index values on the y-axis, or do I have to modify my cell using datenum? If so, any tips on doing that? Thanks in advance, any help is very valuable!!
