### Spectra map

Using the `MAP` command, it is possible to produce a plot of spectra in the current index, arranged in a map. Use the option `/CELL Size_x Size_y` to specify the size of a spectrum, in current angle units. Without this option a default is taken (the actual separation of the spectra). Option `/GRID` will produce frames around the spectra. The argument `MATCH` can be given to fix the aspect ratio of the boxes to the cell sizes.

The map size can be controlled using commands `SET PAGE` and `SET BOX_LOCATION`. Labels can be suppressed by option `/NOLABEL` (and ticks will not be drawn if of size 0.0). Option `/NUMBER` will add the observation number with each spectrum.

After the `MAP` command has been used, the `POPUP` command may be used to display in another window a spectrum selected either from its observation number or from its offsets. `POPUP` can also be used after the `STAMP` command. The `STAMP` command allows to display many observations at once, without requesting the X and Y axis scales to be fixed.
