MATLAB: Control histogram appearance: width of bars

appereancebarwidthbinshistogramMATLAB

Hi, I'm plotting the following histogram:
h1 = histogram(FIBR);
h1.Normalization = 'probability';
h1.BinWidth = 100;
I want to the bars to be thinner so I've called
h1 = histogram(FIBR,'BarWidth',0.5);
But I get the following error:
Error using histogram>parseinput (line 211)
Expected input to match one of these strings:
'BinEdges', 'BinLimits', 'BinLimitsMode', 'BinMethod', 'BinWidth', 'BusyAction', 'ButtonDownFcn', 'CreateFcn', 'Data', 'DeleteFcn', 'DisplayName', 'DisplayStyle',
'EdgeAlpha', 'EdgeColor', 'FaceAlpha', 'FaceColor', 'HandleVisibility', 'HitTest', 'Interruptible', 'LineStyle', 'LineWidth', 'Normalization', 'NumBins',
'Orientation', 'Parent', 'PickableParts', 'Selected', 'SelectionHighlight', 'Tag', 'UIContextMenu', 'UserData', 'Visible'
The input, 'BarWidth', did not match any of the valid strings.
Error in histogram (line 118)
[opts,args] = parseinput(args,~isempty(cax));
And I'm really confused because I'm following the manual:
MathWorks – Control Histogram Appereance

'BarWidth' option only applies to histograms of categorical data. Is your FIBR categorical or numerical?
The following is one of the example from the documentation:
A = [0 0 1 1 1 0 0 0 0 NaN NaN 1 0 0 0 1 0 1 0 1 0 0 0 1 1 1 1];
C = categorical(A,[1 0 NaN],{'yes','no','undecided'});
h = histogram(C,'BarWidth',0.5);
If FIBR is of some discrete values, you can convert it to categorical then use BarWith property.
