### 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.
