More options for displaying multiple traces in a plot

[pgleeson]

Once a plot is created with multiple traces (e.g. with this: #160) it would be good if there were options in the menu to be able to view the plot in multiple ways (different datasets in these examples):

• Default:

• Stacked (optional parameter for spacing/scaling, e.g. >100% can be used in traces similar)

• Heatmap

• Simple Spike raster (optional parameter: threshold for spiking)

• Simple rate plots (i.e. spike freq generated from above; optional param: bin size)
