How to rotate histograms?

How to plot histogram on the y-axis?

Answer 1

[Image Analyst]

Did you look at the bottom of the bar() documentation in the "See also" section and notice the barh() function? Does that do what you want?

[Mr M.]

Barh is ok, but I want it on the right side. How to force that?

[Image Analyst]

Maybe try experimenting with the xdir property of the axis, something like

set(gca, 'xdir', 'reverse');

Dear Image Analyst,

hope you are still reading in these days, just to say that your tip worked for yaxis of barh too.

Thanks for your help.

I attach the code for the community.

b2 = barh(GSCS.GroupCount, 'FaceColor', 'flat');
myColor=rand(height(GSCS.GroupCount), 3);
b2.CData = myColor;

yticklabels = repmat('A', ...
    height(GSCS.SuperstructureConstructionSystem), 1);
yticklabels = string(yticklabels);

for i = 1:height(GSCS.SuperstructureConstructionSystem)
    yticklabels(i) = GSCS.SuperstructureConstructionSystem(i);
end

xlabel('No. of bridges', 'FontSize', 12);
ylabel('Superstructure Construction System', 'FontSize', 12);

% xtickangle(90);
ax = gca;
ax.XAxis.FontSize = 12;

ax.YTick = 1:1:height(GSCS.SuperstructureConstructionSystem);
ax.YAxis.TickLabels = yticklabels;
ax.YAxis.FontSize = 8;
set(ax, 'ydir', 'reverse')

Best.

If you're using the HISTOGRAM function, see the Orientation property of the Histogram object that function returns.
