Representing certain range of X axis using a single tick in MATLAB plot

I have the following data:

X = [1,2,3,4,5,6,7];

Y = [10,10,10,10,20,30,40];

bar(X,Y)

For X axis value until 4, the Y axis value is the same which is 10. I want to represent the barplot where the first X axis tick will show 1:4 and Y axis value will show 10. For the other X axis values from 5 to 7 will be represented each using a single tick as usual, for example X axis will be 1:4 5 6 7, so 4 ticks in total in X axis. Please let me know how to do that.

Two options

X = [1,2,3,4,5,6,7];
Y = [10,10,10,10,20,30,40];

xIdx = [1,5,6,7]; 
bar(X(xIdx), Y(xIdx))
ax = gca(); 
ax.XTick = xIdx; 
ax.XTickLabel{1} = '1:4';

xIdx = [1,5,6,7]; 
bar(Y(xIdx))
ax = gca(); 
ax.XTick = 1:numel(xIdx); 
ax.XTickLabel = {'1:4','5','6','7'};

Thank you!

Also see the width variable in bar() if you'd like the 1:4 bar to spread out across all 4 x-values in the first option, although you'd need to either plot it separately or use a grouping variable.

Sounds good, appreciate it.
