To define the axes for just one subplot colorabar

*For subplot(1,7,5)- I want to define the range of colorabar [0 6]*

subplot(1,7,4)
m_proj('Stereographic','lat',90,'long',300,'radius',35,'rect','on');
m_contourf(long,lat,oct_skw_anom ,'linestyle','none');
m_grid('linewi',1,'tickdir','out',...
        'xtick',6,'ytick',[72 76 80 84 88 90]);  
m_coast('patch',[.6 .6 .6],'edgecolor','k');
m_elev('contour',[ ],'edgecolor',' ');   
colorbar( 'location','southoutside');

subplot(1,7,5)
m_proj('Stereographic','lat',90,'long',300,'radius',35,'rect','on');
m_contourf(long,lat,oct_kts_anom ,'linestyle','none');
m_grid('linewi',1,'tickdir','out',...
        'xtick',6,'ytick',[72 76 80 84 88 90]);  
m_coast('patch',[.6 .6 .6],'edgecolor','k');
m_elev('contour',[ ],'edgecolor',' '); 
caxis = ([0, 6]);
h = colorbar(caxis, 'southoutside');

[Muhammad Usman Saleem]

there is an error

Undefined function 'm_proj' for input arguments of type 'char'.

in this line

m_proj('Stereographic','lat',90,'long',300,'radius',35,'rect','on');

There are two different things you could mean here.

One is that you want the colormap to start where the data = 0 and end where the data = 6. You actually do that with the axes object, not the colorbar. The colorbar is just showing the mapping that the axes is using.

The subplot command returns a handle to the axes. So you'd want to do something like this:

ax = subplot(1,7,5)
m_proj('Stereographic','lat',90,'long',300,'radius',35,'rect','on');
m_contourf(long,lat,oct_kts_anom ,'linestyle','none');
m_grid('linewi',1,'tickdir','out',...
        'xtick',6,'ytick',[72 76 80 84 88 90]);  
m_coast('patch',[.6 .6 .6],'edgecolor','k');
m_elev('contour',[ ],'edgecolor',' '); 
caxis(ax,[0 6])
colorbar('southoutside')

Note, you had a variable named caxis, that's also the name of the function you use to set the color range on the axes, so you might get a conflict there. You probably want to rename that variable and clear it from your workspace.

The other thing you might mean here is that you only want the colorbar to show a portion of the color range. This won't change the mapping between data values and colors. It's just like "zooming in" on the colorbar. The details of how you do this has changed a bit in the last couple of versions of MATLAB, but in R2016a, you would do this:

c = colorbar('southoutside');
c.Limits = [0 6];

or this:

colorbar('southoutside','Limits',[0 6])

The second option is what i want to use but for R2012b. When i tried this

   c = colorbar('southoutside');
    c.Limits = [0 6];

• Warning: Struct field assignment overwrites a value with class "double". See MATLAB R14SP2 Release Notes,Assigning Nonstructure Variables As Structures Displays Warning, for details. *

colorbar('southoutside','Limits',[0 6])

The error is Unknown property 'Limits'. How do i define Limits here?

[Sophia]

I just want to make the colorbar emphasise on 0-6 range.

[Mike Garrity]

I don't really remember colorbar in R2012b, but I think you want

xlim(c,[0 6])

[Muhammad Usman Saleem]

caxis([0, 6])
>> colorbar

[Sophia]

Thanks this works too..:-)

[Muhammad Usman Saleem]

I got confuse, whether this simile is for me or for some other comments? =D

Answer 2

[Muhammad Usman Saleem]

For setting range of your own desire, try this please

caxis([0, 6])
>> colorbar

Thanks it works!
