enter values from 0 to N (imposed value) with step of 100 on the x-axis of the bar graph

Hi. I need to change the values on the x-axis of a bar graph.

I have tried in the following way but it doesn't seem to work. Why? How can I enter values from 0 to 700 (imposed value) with step of 100 on the x-axis of the bar graph?

matrix = [64 440; 65 489; 66 581; 67 563];

figure
hbh = barh(matrix(:,1), matrix(:,2));

N = 700;
  
step = 100;
vector_x_axis = 0:step:N;
xticks(vector_x_axis)

hello Alberto

welcome back !

i suppose you wanted to do this

matrix = [64 440; 65 489; 66 581; 67 563];
figure
hbh = barh(matrix(:,1), matrix(:,2));
N = 700;
  
% step = 100;
% vector_x_axis = 0:step:N;
% xticks(vector_x_axis)
xlim([0 N])

Hi Mathieu! Okay, but what if I want to change the step as well?

matrix = [64, 440; 65, 489; 66, 581; 67, 563];
N = 700;
step = 140;

figure
hbh = barh(matrix(:, 1), matrix(:, 2));
xlim([0 N])
vector_x_axis = 0:step:N;
xticks(vector_x_axis)

thanks!

I'm not exactly sure what you want to see. Are one of the 3 graphs below what you want?

matrix = [64, 440; 65, 489; 66, 581; 67, 563];
N = 700;
step = 100;
vector_x_axis = 0:step:N;

figure
hbh = barh(matrix(:, 1), matrix(:, 2));
xlim([0 700])

figure
hbh = barh(matrix(:, 1), matrix(:, 2));

xticks(vector_x_axis)
xticklabels(vector_x_axis(2:end))

figure
hbh = barh(matrix(:, 1), matrix(:, 2));
xticks(vector_x_axis)
step = 700/6;
vector_x_axis = 0:step:N;
xticklabels(vector_x_axis)

Thank you for your reply @Kevin Holly.

The final graph I want to get is the first one you showed me, BUT I want to impose on the x-axis a range taking into account both the final 'N' value (700) and the 'step' value.

For example using this code that has N=700 and step=50:

matrix = [64, 440; 65, 489; 66, 581; 67, 563];
N = 700;
step = 100;
vector_x_axis = 0:step:N;

figure
hbh = barh(matrix(:, 1), matrix(:, 2));
xticklabels(vector_x_axis)

a graph is created where the x-axis ranges from 0 to 300 (and not up to N=700) and with steps of 50

Whereas by modifying only the last line:

xticks(vector_x_axis)

In both graphs, the x-axis does not arrive at the value of 700.

I'm still not quite sure what you want.

matrix = [64, 440; 65, 489; 66, 581; 67, 563];
N = 700;
step = 50;
vector_x_axis = 0:step:N;

figure
hbh = barh(matrix(:, 1), matrix(:, 2));
xticks(vector_x_axis)

figure
hbh = barh(matrix(:, 1), matrix(:, 2));
xticks(vector_x_axis)
xlim([0 700])
