bar graph with non numerical x-axis

I have data which I have attached to the question (T_Stand_For_Sum). I want to display the first column as x-axis points, with the second column values as the bar heights. I have tried the following and recieved the following errors

xbar = T_Stand_For_Sum.ADBStand;
ybar = T_Stand_For_Sum.KWH;
bar(xbar,ybar);

Error using bar (line 41)

Not enough input arguments.

Error in Model_V_04 (line 234)

bar(xbar,ybar);

xbar = categorical({'T_Stand_For_Sum.ADBStand'});
ybar = T_Stand_For_Sum.KWH;
bar(xbar,ybar);

Error using bar (line 213)

Data inputs must match the axis configuration. A numeric axis must have numeric data inputs or data

inputs which can be converted to double.

Error in Model_V_04 (line 232)

bar(xbar,ybar);

bar(categorical(T_Stand_For_Sum{1:k, 1}), T_Stand_For_Sum{1:k, 2});

Error using bar (line 213)

Data inputs must match the axis configuration. A numeric axis must have numeric data inputs or data

inputs which can be converted to double.

Error in Model_V_04 (line 223)

bar(categorical(T_Stand_For_Sum{1:k, 1}), T_Stand_For_Sum{1:k, 2});

Try this:

bar(categorical(T_Stand_For_Sum.ADBStand),T_Stand_For_Sum.KWH)

I still recieve an error with this line of code

Error using bar (line 213)

Data inputs must match the axis configuration. A numeric axis must have numeric data inputs or data

inputs which can be converted to double.

Error in Model_V_04 (line 238)

bar(categorical(T_Stand_For_Sum.ADBStand),T_Stand_For_Sum.KWH)

[Mark Maders]

T_Stand_For_Sum is a table. Is this why the error is appearing? I have tried converting it to other formats but cannot manage that either

[Simon Chan]

Forgot to mention one step:

(1) You may close figure 1 and then run the script, or

(2) Put figure 2 as follows, you will get two figures

load('T_Stand_For_Sum.mat');
figure(2);
bar(categorical(T_Stand_For_Sum.ADBStand),T_Stand_For_Sum.KWH)

thank you that is working now

Simon's solution is one way to do it. But using categorical just to label the bars is kind of an abuse of categorical, which is intended to represent data where you have a large number of elements drawn from a small number of discrete values. Lots of repeated values.

Another way to label the bars is to just label them:

>> bar(T_Stand_For_Sum.KWH)
>> set(gca,"XTick",1:33,"XTickLabel",T_Stand_For_Sum.ADBStand)
