How to put strings on the x axes

Hello,

I want to plot types of methods vs their corresponding numbers. That is, X axes will be string and Y axes will be numbers. Currently, my matrix is cell as below:

neworder =

    'N2'            [0.1700]
    'HC'            [0.1700]
    'SAGD'          [0.1800]
    'Steamflood'    [0.4500]
    'CSS'           [0.4500]
    'hot Water'     [0.4500]
    'CO2'           [0.5100]
    'Polymer'       [0.6300]
    'ASP'           [0.6300]
    'Combustion'    [0.6500]

I tried to plot string vs. numbers. It didn't work out. Basically, my X axes is the first column and Y axes is the second column.

Thank you,

neworder = {
    'N2'            [0.1700]
    'HC'            [0.1700]
    'SAGD'          [0.1800]
    'Steamflood'    [0.4500]
    'CSS'           [0.4500]
    'hot Water'     [0.4500]
    'CO2'           [0.5100]
    'Polymer'       [0.6300]
    'ASP'           [0.6300]
    'Combustion'    [0.6500]}
bar([neworder{:,2}])
set(gca,'XtickL',neworder(:,1))

With Matlab R2016a I need to use 'XtickLabel'

I have a similar problem.

I am trying to do this in my code

data_strings = {...
    '-[(u^\prime\cdot\nabla)\omega_r^\prime]^*'         [-2.5 -1.6 -1. -2.1 -1.25 -0.85]...
    '[(\omega^\prime\cdot\nabla)u_r^\prime]_\perp^*'    [0.15 0.05 0.01 2.2 1.04 0.5]...
    '[(\omega^\prime\cdot\nabla)u_r^\prime]_{||}^*'     [0.3 0.25 0.1 -1.3 -0.65 -0.62]...
    '[-(2\Omega\cdot\nabla)u_r^\prime]^*'               [0.87 0.7 0.77 1 0.81 0.79]
    '[\nu\nabla^2\omega_r^\prime]^*'                    [0.6 0.42 0.3 0.12 0.17 0.05]};

But I keep getting the following error.

Error using vertcat

Dimensions of matrices being concatenated are not consistent.

Is there a way I can make this work?

[Thomas]

figure1 = figure;

axes1 = axes('Parent',figure1,'XTickLabel',neworder(:,1));
box(axes1,'on');
hold(axes1,'all');

% Create plot
plot(cell2mat(neworder(:,2)));

or

 bar(cell2mat(neworder(:,2)))

Thank you:)
