===== Change of all scan names =====

Open iPython console and write commands.

To see temperature in legend of charts:

    for aa in D:
         if hasattr(aa, 'data'):
             aa.data.oldname=aa.data.name
             aa.data.name=aa.data.environment[0]
             

To put some parameter to all scan titles (in this example it is parameter gamma):

    for aa in D:
         if hasattr(aa, 'data'):
             aa.data.oldtitle=aa.data.meta.title
             aa.data.meta.title += ', stt=%0.2f' % aa.data.meta.gamma

===== Fit curve from the file =====

It is possible to have a spectrum/background stored as a xy points in ASCII datafile. This command will load that file, interpolate between the loaded values and then fit the scale of such model. Just add this line to the **Model definition**:
     
     Custom('MyBg', 'scale', "(lambda data: scipy.interpolate.interp1d(data[0], data[1], kind='cubic')(x) * scale)(numpy.loadtxt('C:\bg.txt').T)")

Replace **C:\bg.txt** with path to your ASCII file. **MyBg** can be also changed - this is just name of your model.
