How to adjust axes and grid in GUI matlab? how to get more precision for example [-1 -0.5 0] other than [-1 0]

I would like to make the axes and the grid more precise as shown in the image below but i dont know how . i would like that when i pass the cursor on a point it gives me its coordinates x and y.If this is not possible in GUI can i just adjust the axes and make them more precise? thanks :)

Hi dhouha

This is exactly the same as the matlab programming in M-File and you have to use the following command where exactly you plot the figure in GUI. I give you an example;

x = 1:10;
y = x .^ 2;
plot(x, y)
grid on
axis([0 20 0 15]) % axis([x_min x_max y_min y_max])

Regards,

Presuming the handle to the axes is hAx for brevity,

xLim=xlim(hAx);  % return the current x limits for the axes
set(hAx,'xtick',[xLim(1):0.5:xLim(2)])  % set the tick marks (may be _too_ dense to see all)

You can also experiment with

'XMinorGrid', 'on|off'
'XMinorTick', 'on|off'

See

doc axes % Axes Properties for details on above

For input

doc ginput

where should i exactly put this code please ? i have callbacks etc....

[dpb]

Wherever the axes is created and/or when it needs updating if changing axes inside the callback so should reflect those changes.
