Change number of xTicks

Hello, I am trying to make a graph like a boxplot using rectangles. I draw them in the figure to represent intervals. What I want is to appear something like, in the x-axis the name of the persons and in the y axis the intervals of the numbers they have.

For example:

If Peter has [1,2] and [3,4] I want the graph something like this :

But what I'm getting is this :

I use: ax = gca; set(ax, 'xticklabel', names);

to change the x-axis but what I need now is for the names to appear only once not many times.

Can anyone help me?

Where is your code? a code that we can test

    names = {'Peter'};
    w = 0.5;            % Rectangle Width
    figure(1);
    axis([0 1   0 20]);
    rectangle('Position',[1-w/2  1 0.5  2], 'LineWidth',2);
    ax = gca;
    set(ax, 'xticklabel', names);

You will have to experiment with your code, but when you set 'XTickLabel' values it is necessary to specify the 'XTick' locations as well.

For example:

names = {'Peter' 'Jürgen' 'Elizabeth' 'Jennifer'};

figure(1)
scatter(rand(10,1), rand(10,1))
xtk = get(gca, 'XTick');                                % Get 'XTick' Data For Information
set(gca, 'XTick', [1:2:8]/10, 'XTickLabel', names)

The line for ‘xtk’ will help you determine where the plotting command puts the 'XTick' values. It is helpful, but may not be necessary in your final code.

It is exactly that! Thank you so much
