Python decision making code

[roro]

I am trying to make the code below make decisions between two different data sources. Basically, if the data source is m_mas it should go through one set of processes, and if it is m_rma, the coding should go through another set of processes.

I am not sure if I am using the decision making syntax correctly and would appreciate any help. Thanks.

if self.dataSource == "m_mas":
		  if maxSignalInDatasource < 1000:
			# the little graph on the tga image has a scale
			# such that 1 unit is 0.031 pixels for the range 0-1000
			# Also it is displaced to the right by some pixels
			offsetX = maxSignalInDatasource*0.029
			offsetX += (displaceX + 23)
			int(offsetX)
			draw.line((offsetX, top1, offsetX, bottom), fill='#cccccc')
		    elif maxSignalInDatasource > 1000:
			# the little graph on the tga image has a scale
			# such that 1 unit is 0.003222 pixels for the range 1000-10000
			# This bit of the graph is displaced another 31 pixels
			offsetX = maxSignalInDatasource*0.0029
			offsetX += (displaceX + 48)
			int(offsetX)
			draw.line((offsetX, top2, offsetX, bottom), fill='#cccccc')
		      elif viewMaxSignal1 < 1000:
			# the little graph on the tga image has a scale
			# such that 1 unit is 0.031 pixels for the range 0-1000
			# Also it is displaced to the right by some pixels
			offsetX = viewMaxSignal1*0.029
			offsetX += (displaceX + 23)
			int(offsetX)

		         elif viewMaxSignal1 > 1000:
			# the little graph on the tga image has a scale
			# such that 1 unit is 0.003222 pixels for the range 1000-10000
			# This bit of the graph is displaced another 31 pixels
			offsetX = viewMaxSignal1*0.0029
			offsetX += (displaceX + 48)
			int(offsetX)
			draw.line((offsetX, top2, offsetX, bottom), fill=red)
		    elif mode == 'Compare':
			if viewMaxSignal2 < 1000:
			    	# the little graph on the tga image has a scale
