I have a data set where I have alternatingly positive and negative values for each year. I need to plot them on a bar chart but the 2nd bar must start where the first bar ends. I cannot make it work with changing basevalue and can't find anyother option.

For example,

y = [4 2 3;

1 6 5]';

n=size(y,1);

dy=([1,-1].*y).';

yc=[0, repelem(cumsum(dy(:).'),2)];

ymin=min(yc(:));

lims=sort(reshape(yc(1:end-1),2,[]))-ymin;

ys=[lims(1,:); diff(lims)]';

h=bar(ys,'stacked','FaceColor','flat','ShowBase',0);

h(1).Visible='off';

h(2).CData(1:2:end,:)=repmat( [0 0 1] ,n,1);

yticklabels( str2double(yticklabels) +ymin + "")

well when i simply run this code it, the two mentioned lines open up a new figure. I changed the following code

h=bar(ys,'stacked','FaceColor','flat','ShowBase',0);

h = bar(app.Bar_tab_16, ys,'stacked','FaceColor','flat','ShowBase',0);

where app.Bar_tab_16 is the name of the axes where i am plotting my chart. But since i don't know how to change the remaining two lines so that I can add the names of the axes, it opens up a new figure and the plot is also different in app designer than simply running it in script file.
