[FieldTrip] Plotting confidence intervals in multiplotER

[kousik sarathy]

Hey Arti,

This is not such a trivial thing to solve. Here's a recipe I used. You need
to find and edit two scripts. If this spurns any more interest, I'll
initiate a 'bug' and try to send in a pull request. This is a dirty fix and
in all probability will be considered blasphemy.  ;)

1. Find in ft_multiplotER
<https://github.com/fieldtrip/fieldtrip/blob/master/ft_multiplotER.m#L704>:
ft_plot_vector(xval, yval, 'width', width(m), 'height', height(m), 'hpos',
layX(m), 'vpos', layY(m), 'hlim', [xmin xmax], 'vlim', [ymin ymax], 'color',
color, 'style', cfg.linestyle{i}, 'linewidth', cfg.linewidth, 'axis',
cfg.axes, 'highlight', mask, 'highlightstyle', cfg.maskstyle, 'label',
label, 'box', cfg.box, 'fontsize', cfg.fontsize);
This basically calls a plotting function which in turn does the plotting
for you. You need to send in the extra 'sem' or a 'ci' variable.
Change this to:
ft_plot_vector(xval, yval, 'ysem', ysem, 'width', width(m), 'height',
height(m), 'hpos', layX(m), 'vpos', layY(m), 'hlim', [xmin xmax], 'vlim',
[ymin ymax], 'color', color, 'style', cfg.linestyle{i}, 'linewidth',
cfg.linewidth, 'axis', cfg.axes, 'highlight', mask, 'highlightstyle',
cfg.maskstyle, 'label', label, 'box', cfg.box, 'fontsize', cfg.fontsize);

2. Find in ft_plot_vector
<https://github.com/fieldtrip/fieldtrip/blob/1b624e4e84cfd9e99e99cb391c91e961a03eea07/plotting/ft_plot_vector.m#L318>
:
You need to first get the sem parameter from your data and setup so FT can
see your sem or CI info. Follow the code here
<https://github.com/sarathykousik/sefSourceAnalysis/blob/master/multiplotER-bounded.m>
.
Search for "data_sem" and fix those lines.
Then:
h = plot(hdat, vdat, style, 'LineWidth', linewidth, 'Color', color, '
markersize', markersize, 'markerfacecolor', markerfacecolor);
Change this to:
[h hp ]= boundedline(hdat, vdat, vdat_sem);

Boundedline
<https://www.mathworks.com/matlabcentral/fileexchange/27485-boundedline-m>is
a submission in the MATLAB file exchange. You can use any other thing.


Good luck trying! :)
