Plotting data by group ?

Hello,

I am a Neuroscientist trying to create some script on MATLAB to replace my truly old Statview program.

All my dataset look like :
Genotype Number Var1 Var2 Var3 Var4 Var5 Var6
KO 464 2.85 2.65 0.35 1.5 2.35 3.45
KO 455 2.06 0.69 0.7 1.45 2.4 3.05
KO 465 0.89 1.1 0.8 1.45 2.45 2.95
KO 472 2.17 0.5 0.55 1.45 2.2 2.85
KO 473 2.52 1.69 0.65 1.4 1.65 2.5
WT 466 0.24 2.29 0.8 1.25 1.95 2.5
WT 467 2.03 0.67 0.85 1.6 2.5 3.15
WT 468 1.28 1.27 0.75 1.55 2.25 2.9
WT 470 2.08 1.19 0.85 1.4 2.4 3

I was looking for a simple way to plot :
- the mean of each group (WT or KO in my example) for each Var
- add the standard error
- plot on the y-axis Var1 to Var 6 and the x-axis with the label on the first columm (Var1 to Var6 in text format)

I find this : http://www.icn.ucl.ac.uk/motorcontrol/toolboxes/toolbox_graph.htm
But it plot only x and y numerical values, or my x value are only "label".

I would like to plot something like that : http://www.icn.ucl.ac.uk/motorcontrol/toolboxes/pics/lineplot_1.jpg
But not with 5, 7, 10, 20 on the x axis, only with "Var1" "Var2" ... "Var6".

Did someone have an idea ?

It is really common in my field for the figure in paper, so, i was thinking someone made something... ^^

Thank a lot !
