I have a table from excel from values every 15 minutes from a whole year, the excel table only have 2 columns: DATETIME and VALUE. But when I plot the data, the shape of the plot has a very sharp form. The simplest solutios to make the plot softer, I think, is to calculate the mean for every hour (4 values) and plot them. After searching I found the function tsmovavg, but this function don't do the skip every 4 values, instead of that, can calculate the mean of the last 4 positions of the vector. How can I do to make my script possible?.If you have and example of something very similar to this I would be very greatful to see it.
