[x] There must be an option for 1-1 synchronization. Right now for each .omf/.ovf there are usually multiple datapoints form .odt/.txt plotted, while there should be an option for drawing ONLY a datapoint corresponding to the particular .omf/.ovf. So, despite we have more data in plot file, we draw only as many points as there are .omf/.ovf
[x] We should synchronize framing from all widget at the same time
