Bar figure helps with group on the x-axis

Hello everyone, I need help with grouping my data, where the central value on the x-axis is the corresponding number, not approximations.

x = [1.2132312 5.3413413212];
vals = [1.12234 1.34234 0.52342741238 2.4132213 3.1231232 5.123123 8.123123;5.793371156 10.506158125 1.23213 1.3123 1.5 1.5 1.5]

vals = 2×7

1.1223 1.3423 0.5234 2.4132 3.1231 5.1231 8.1231 5.7934 10.5062 1.2321 1.3123 1.5000 1.5000 1.5000

b = bar(x,vals,'grouped');

For example, the group of 7 bars that comes out below only the number 1.2132312 and for the other set the number 5.3413413212

Like this?

x = [1.2132312 5.3413413212];
vals = [1.12234 1.34234 0.52342741238 2.4132213 3.1231232 5.123123 8.123123;5.793371156 10.506158125 1.23213 1.3123 1.5 1.5 1.5];
b = bar(x,vals,'grouped');
set(gca(),'XTick',x)

Or this?

b = bar(x,vals,'grouped');
ax = gca();
ax.XTick = x;
ax.XAxis.TickLabelFormat = '%.10f';

Or this?

b = bar(x,vals,'grouped');
ax = gca();
ax.XTick = x;
ax.XTickLabel = {'1.2132312' '5.3413413212'};
