| | 161 | * 'timeave' : The time average defines the duration on which the files have been averaged. For instance, you will have '1m', '1mm', '1y', '32y'. You may add a trend to that : do you want to remove the seasonal cycle from the time series ? Thus the trend shoud be @t412. Or if you want to write data in another netcdf file, the trend should be @t9 (in that case, you will also have to define the 'out' parameter â see below). |

| | 175 | |
| | 176 | * 'date1' : The name of the netcdf file should have some indications of dates (for instance, 2L24_1m_186001_195912_grid_T.nc). If you only want to visualize the monthly mean SST of May 1871, you will have to specify 187105 as the 'date1' parameter. It is not compulsory to specify any final date for the 'spec' parameter in that case : '-' will be enough. The dates specified in the name of the file and the dates specified in post_it.pro should be coherent since the netcdf file only contains time steps : in our example, May, 1871 should corresponds to the 137th time step in the file. Dates can go down to daily scales (18710510) and you can even specify seconds. |

| | 183 | * 'spec' : This parameter has two meanings. It may define the ending date of a 1d plot (SST anomaly averaged over nino_3 region as a function of time). But it may set parameters for a to make differences between two plots : this is the second way to make differences. |

| | 190 | |
| | 191 | * 'disp' : the kind of display is set with this parameter. You can specify if you want several plots on the same window and how they will be organised on it. By default, plots are carried out with a landscape view. For the example below, 'disp' is set to '2x2' and the plot would have been the same with '2x2L'. Please notice that you don't have to set 'on' to '1' at each line : the first line is enough ; post_it understands that it has to consider four lines for the plot. |
