Is it possible to create a bar graph with different x-Axis scale/labeling?

Hi,

I am trying to create a bar graph that looks like this:

On the x-Axis I would like to have the bars for WP on the very left with one bar distance to the bars from -12 to 20°C and then again the bars for SHVK on the very right with one bar distance.

Furthermore I am working with a table and I was wondering if it would work if i write WP and SHVK in the collumn for the temperature or if i'd have to use a different way of working with the table. Because at the moment I have 0 as the temperature but that gives out a wrong graph as there are three values for 0 on the x-Axis.

I have attached the table I am working with. I want to plot out.combinednew.([3,9,12]).

Thanks!

Set the first/last x values to min(x)-2/max(x)+2, respectively, then set the ticklabels for those two manually.

y = [2 2 3; 2 5 6; 2 8 9; 2 11 12];                 % from bar() example for grouped
x=[0:length(y)-1]-2;                                % simulate similar x
y=[y(1,:);y;y(end,:)]; y(1,end)=0; y(end,1)=0;      % augment y similar to desired
x=[x(1)-2 x x(end)+2];                              % fixup the x vector with gap
subplot(2,1,1)
bar(x,y);                                           % default look to match
subplot(2,1,2)                          % now fixup the ticklabels as desired
bar(x,y);                               % base plot
LABELS={'WP','SHVK'};                   % the specific group labels wanted
hAx=gca;                                % get the axis handle
hAx.XTickLabels([1,end])=LABELS;        % write those two in place of default

thanks a lot, that's exactly what I was looking for! :)
