Overlay of plots from the two O2k-Chambers in a DatLab file is achieved by selecting the corresponding Graph layout. Superimposed traces of flux/flow from chambers A and B are then shown in Graph 1, and of concentration in chambers A and B in Graph 2.
There are basically two ways to superimpose traces recorded in different experiments: Export of the graphics via windows metafile or export of the data to e.g. a spreadsheet program.
If you export via wmf you also can manipulate the graphics but then usually the lines are broken up in different segments. This can be done in various programs like MS Word, Open Office Draw and even in MSPower Point, though this maybe is the worst program to do this. It is better to manipulate them in a proper program like OO Draw, convert it to an unchangeable picture and then import it to a presentation graphics. Anyway, when you import directly to Power point (or other programs), make sure not to import it as a "picture" but as a metafile. Also in some programs you might afterwards have to "break" it up, or accept a "conversion to a MS Draw object" or other similar linguistic inventions of the software gurus. For this option we suggest to do as much as possible directly in DatLab (setting colors, line widths, ..) using the options in "Plots"/"select plots" and "graph"/"options".
The “hardcore“ option is to export the data and import it into e.g. a spreadsheet program (MS Excel , OOCalc). It takes longer to have a simple overlay but gives you far less problems later and its easier to make changes later. To do this you can export your dataset "Export"/"Data to Textfile" and then go from there.
