There is a Matlab function that plot the min and max of a set of data and represent it with 2 horizontal lines and one vertical line as showed on the picture.
I am looking for that function.

How about adding a label at each end of the slider to indicate "min" to "max," and use the correct value (ex. -1*sl.Value in the following example) inside the program ?
h = figure;sl = uicontrol(... 'Parent', h,... 'Units', 'normalized',... 'Position', [0.2 0.5 0.6 0.05],... 'Style', 'slider',... 'Min', -1,... 'Max', 1);uicontrol(... 'Parent', h,... 'Units', 'normalized',... 'Position', [0.1 0.5 0.1 0.05],... 'Style', 'text',... 'FontSize', 12,... 'String', '+1');uicontrol(... 'Parent', h,... 'Units', 'normalized',... 'Position', [0.8 0.5 0.1 0.05],... 'Style', 'text',... 'FontSize', 12,... 'String', '-1');
An accumarray call can do that relatively easily:
D = load('test.mat');task = D.task;time_s = D.time_s;TFmin = islocalmin(task, 'MinProminence',10); TFmax = islocalmax(task, 'MinProminence',10);MinIdx = find(TFmin);MaxIdx = find(TFmax);Idx = sort([MinIdx; MaxIdx]);IdxCell = accumarray(Idx(1:numel(Idx)-1), (1:numel(Idx)-1).', [], @(x){Idx(x):Idx(x+1)}); % Cell Array Of Index Ranges
IdxRng = find(cellfun(@(x)~isempty(x), IdxCell)); % Index Ranges
GetData = @(x) [time_s(IdxCell{IdxRng(x)}), task(IdxCell{IdxRng(x)})]; % Function To Retrieve Data Easily
Get1 = GetData(1); % Get First Set
X1 = Get1(:,1);Y1 = Get1(:,2);Get3 = GetData(3); % Get Third Set
X3 = Get3(:,1);Y3 = Get3(:,2);figureplot(time_s,task, time_s (TFmin),task(TFmin),'r*')hold onplot(time_s,task,time_s(TFmax),task(TFmax),'b*')plot(X1, Y1, '.r') % Plot First Set
plot(X3, Y3, '.g') % Plot Third Set
hold offProducing this example plot:
Thius code recovers all of the intervals, not only the ascending ones, so choose the odd-numbered arguments to ‘GetData’.
