Plot - Remove axis ticks but keep grid lines

Hi,

I am producing a graph to view open source polysomnography data. I have several arrays in one plot window with an offset between them which is fairly standard. I wish to remove the y tick numbers as they aren't required and get in the way of some additional lables. I would like to also include some x and y axis gridlines.

I have implemented the following code below, however the 'set(gca,'ytick',[])' command makes the y gridlines not plot. How can I remove the ytick numbers on the y axis but keep the y gridlines?

Thanks in advance,

Christopher!

% Create a new empty figure 
figure 

% Remove y axis numbering
set(gca,'ytick',[])

% Set major Grid lines
ax.GridLineStyle = '--';
ax.GridColor = 'b';
ax.GridAlpha = 1;
grid on;
% Set minor Grid lines
ax.MinorGridLineStyle = '-';
ax.MinorGridColor = 'b';
ax.MinorGridAlpha = 0.5;
grid minor;

A couple things. You have discovered you have to have ticks to have a grid. However, labels are separate. Leave the ticks and remove the yticklabels.

Also, ax does not automatically refer to the axis properties. You must create ax as an axis object first for that to work. Your code is just creating a structure named ax.

Try this.

% Create a new empty figure 
figure 
ax = gca;

% Remove y axis numbering
yticklabels("")

% Set major Grid lines
ax.GridLineStyle = '--';
ax.GridColor = 'b';
ax.GridAlpha = 1;
grid on;

% Set minor Grid lines
ax.MinorGridLineStyle = '-';
ax.MinorGridColor = 'b';
ax.MinorGridAlpha = 0.5;
grid minor;

Hi Cris,

That makes much more sense and works perfectly. Thank you!
