bar chart 2 data sets side by side with different axis

hold on;

yyaxis left

bar(T3_blocked)

yyaxis right

bar(S1_free)

set(gca, 'XTickLabel',name)

set(gca, 'XTick',1:length(name))

set(gca, 'XTickLabelRotation',45)

hold off;

produces:

how can I have the two bars for each material side by side, so the y-axes are both increasing in the same direction (up)?

You can do that by using abs(S1_free) and specifying the locations and widths of the bars:

T3_blocked = [2 1.95 1.5 0.1 1.4]*1e-7;
S1_free = -[1.4 1.4 1 2.9 2]*1e-4;
name = strcat('PZT-',num2cell('A':'E'));
n = numel(name);

hold on;
yyaxis left
bar((1:n)-0.2,T3_blocked,0.4); % locations, heights, width
yyaxis right
bar((1:n)+0.2,abs(S1_free),0.4); % locations, heights, width

set(gca, 'XTickLabel',name)
set(gca, 'XTick',1:length(name))
set(gca, 'XTickLabelRotation',45)
hold off;

Excellent. Thank you

How about taking the absolute value of S1_free?

bar(abs(S1_free));

This paritially works except the bars are overlapping
