Plot a grouped bar chart

Hi,

I have a script and for some reason I cannot plot a grouped bar chart, or any other plot. This is my script, I ave tried to make other plots with different datasets myt nothing works. Am I missing something obvious?

clc;

concentration = readtable('concentration_metal.xlsx'); %Metal concentrations in the soil samples in mg/kg
conf_interval = readtable('confidence_interval.xlsx'); %95 percent confidence interval for the metal concentration 

soil_1=concentration(4,4:21);
soil_2=concentration(8,4:21);
soil_3=concentration(12,4:21);
soil_4=concentration(16,4:21);
soils=[soil_1 ; soil_2 ; soil_3 ; soil_4]; %combining the average soil concentrations 

%transpose rows to colomns
xc=table2cell(soils);
soils_sec=xc';
soils_tree=cell2table(soils_sec);
soils_final=table2array(soils_tree);
%soils_final=cell2mat(soils_sec);
x={'50 Cr' '52 Cr'  '56 Fe'  '57 Fe'  '60 Ni'  '62 Ni'  '63 Cu'  '65 Cu'  '66 Zn' '68 Zn' '75 As' '78 Se'  '82 Se' '111 Cd'  '114 Cd'  '206 Pb'  '207 Pb'  '208 Pb'};
%x=x';

figure()
bar(soils_final)

Well, we can't try to duplicate because you forgot to attach the data files to go with it...what symptoms do you have--errors, unexpected plot appearance, ...???

Not much to go on here.
