command for which the label on the x axis is not shown

Asked by Locks

Hi,

I am looking for a command so that there are no values on the x axis shown.

I tried this;

set(gca,'xtick',[])

but it's not working, any idea

It works here (R2012a)

    %%
    sdn             = [ 1 : 6 ] + 735370;
    date_strings    = datestr( sdn, 'dd-mmm-yyyy' );
    %%
    plot( [1:6] )
    axh = gca;
    %%
    set( axh, 'XTickLabel', date_strings ) 
    %%
    set( axh, 'XTick', [] ) 

There are neither ticks nor labels on the x-axis.

This example is according to the documentation and it works here.

What could the reason be that it doesn't work for you?

  • you have more than one axes object and the current axes is an "other" axes; not the one you think

Restart Matlab and run this example. I would very surprised it it behaves differently compare to what I see.

Try

set(gca, 'xticklabel', '')

that does not work either

dates=datenum(dataSet(:,1));

this does still show some values on the x axis, what am I doing wrong?

%SPX
SPX=dataSet(:,2);
%VIX
VIX=dataSet(:,3);
plotyy(dates,SPX,dates,VIX);
set(gca, 'xticklabel', '')

Like I said in your duplicate question:

plot(1:10); % Plot some arbitrary sample data.
set(gca, 'xtick', [-inf inf]); % Turn off x-axis.

sorry for the duplicate, I first thought that I haven't saved the first one. however, using your code doesn't work either. do I miss something?

I tried this:

dates=datenum(dataSet(:,1));
%SPX
SPX=dataSet(:,2);
%VIX
VIX=dataSet(:,3);
plotyy(dates,SPX,dates,VIX);
set(gca, 'xtick', [-inf inf]);

Explain why it does not work. It plots something in an axes control "where there are no value displayed on the x axis" just like you asked for.

Give me something we can run:

Undefined variable dataSet.
Error in test3 (line 1)
dates=datenum(dataSet(:,1));

What you are missing is that you used plotyy() without mentioning it to us. plotyy() generates two axes, and makes no promises about what gca() will refer to afterwards. You need to save the output of the plotyy() call and use the appropriate axes from what is returned.
