| PLOTTOPO | Plot concatenated multichannel data epochs in a topographic or rectangular array. Uses a channel location file with the same format as topoplot(), or else plots data on a rectangular grid. If data are all positive, they are assumed to be spectra. |
 | |
| Usage: | >> plottopo(data, 'key1', 'val1', 'key2', 'val2') >> plottopo(data,'chan_locs') % old function call >> plottopo(data,[rows cols]) % old function call >> plottopo(data,'chan_locs',frames,limits,title,channels, axsize,colors,ydir,vert) % old function call |
| Inputs: | |
data |
data consisting of consecutive epochs of (chans,frames) or (chans,frames,n) |
| Optional inputs: | |
'chanlocs' |
[struct] channel structure or file plot ERPs at channel locations. See help readlocs() for data channel format. |
'geom' |
[rows cols] plot ERP in grid (overwrite previous option). Grid size for rectangular matrix. Example: [6 4]. |
'frames' |
time frames (points) per epoch {def|0 -> data length} |
'limits' |
[xmin xmax ymin ymax] (x's in ms or Hz) {def|0 (or both y's 0) -> use data limits) |
'ylim' |
[ymin ymax] y axis limits. Overwrite option above. |
'title' |
[string] plot title {def|'' -> none} |
'chans' |
vector of channel numbers to plot {def|0 -> all} |
'axsize' |
[x y] axis size {default [.07 .07]} |
'legend' |
[cell array] cell array of string for the legend. Note the last element can be an integer to set legend position. |
'showleg' |
['on'|'off'] show or hide legend. |
'colors' |
[cell array] cell array of plot aspect. E.g. { 'k' 'k--' } for plotting the first curve in black and the second one in black dashed. Can also contain additional formating. { { 'k' 'fontweight' 'bold' } 'k--' } same as above but the first line is bolded. |
'ydir' |
[1|-1] y-axis polarity (pos-up = 1; neg-up = -1) {def -> 1} |
'vert' |
[vector] of times (in ms or Hz) to plot vertical lines {def none} |
'regions' |
[cell array] cell array of size nchan. Each cell contains a float array of size (2,n) each column defining a time region [low high] to be highlighted. |
'axsize' |
[x y] axis size {default [.07 .07]} |
