How to set bar beginning value?

Hello Community,

i want to ask a question about bar graph. By default the beginning of each bar is zero-value. I need to show such group of bars (that means no 'stacked' style), while bar beginning shows minimum value and bar ending shows maximum value. Minimum and maximum is not always negative and positive respectively. That means the bar in bar group could just "hang is the air".

How can i do this? I could do this through 'stacked' style, making first bar invicible. But i need exact grouped style.

Please help and thank you!

Could you post an example of the look you are trying to achieve?

of course, sorry if I not clearly told what i want

Answer 1

aH = axes;
minimum = rand(10,3);
maximum = rand(10,3) + minimum;

bH = bar(maximum);
hold on;
bH1 = bar(minimum);

for ii = bH1
    ii.FaceColor = [1 1 1];
    ii.LineStyle = 'None';
    ii.EdgeColor = [1 1 1];
end

for ii = bH
    ii.LineStyle = 'None';
    ii.EdgeColor = [1 1 1];
end

axes('Position',aH.Position,'XTick',[],'YTick',[],'Color','None');

thanks, that's exactly what i wanted to represent!

My pleasure.

If my understanding is correct, what you want to do would be like the following. Is it answering your question??

% Example of min. and max. value of each bar
minimum = [1;-1;3];
maximum = [5;3;7];

h = bar([minimum, maximum-minimum],'stacked','BaseValue',min(minimum));
h(1).Visible = 'off';
set(gca,'YLim',[min(minimum),max(maximum)+1]);

Thanks for the answer. Your understood me correctly, but i have noticed, i need represent a group of bars. In example min and max values of data1 and data2. That's why i need a 'grouped' style

That what i want should look this way:

[Akira Agata]

OK. In that case, maybe bar function is not sufficient and you should make your own bar chart by arranging many rectangle shapes, like:

% Example of min. and max. value of each bar for each group (A&B)
A_minimum = [1;-1;3];
A_maximum = [5;3;7];
B_minimum = [-3;1;1];
B_maximum = [2;5;6];

% Calculate hight of each bar
A_height = A_maximum - A_minimum;
B_height = B_maximum - B_minimum;

% Make bar chart using rectangle
figure
hold on;
for kk = 1:3
rectangle(...
  'Position', [(kk-1)*3,A_minimum(kk),1,A_height(kk)],...
  'FaceColor', 'c');
rectangle(...
  'Position', [(kk-1)*3+1,B_minimum(kk),1,B_height(kk)],...
  'FaceColor', 'g');
end
ax = gca;
ax.XTick = [1,4,7];
ax.XTickLabel = {'group1','group2','group3'};

This is just what I am looking for! Thank you very much!

Which would be the way to have this in a 3D plot? I have different set of values which would need to be plot in a third axis.

Thank you very much!

I have a similar issue. I want a bar chart where the bottom of the bar is at some minimum value and the top of the bar is at some maximum value. Does Akira Agata’s code work when there are negative elements? In the second bar, the bottom of the bar should be at -1 and the top of the bar should be at 3. However, when I used this code, the top of the second bar is at 4.

Amazing, thank you.
