Plot two cell strings

Here is my code, I want to plot the B as the X-axis and C as the Y-axis in one plot. At the same time, show the time value of B on the X-axis. I have tried different ways but no success achieved. Could anyone please help me with this problem?

Thanks

A=dataset('file','xxx.csv','delimiter',',','ReadVarName','off');
rows=size(A,1);
FormatOut=13;
for i=1:2:rows-1
  B{(i+1)/2}=datestr(str2double(A{i+1,3}),13);
  C{(i+1)/2}=str2double(A{i+1,7});
end

B = str2double( A(1:2:end, 3) );
C = str2double( A(1:2:end, 7) );
plot(B, C);
datetick('X', 13);
