3D Surf linkdata brush delete selected data

Hi there,

I am attempting to visually select data from a surface plot using the "Brush" mode in order to delete the selected data.

The problem I encounter is that everytime I select data using brush as well as linkdata to update the source variables I only get to select the data columnwise; meaning I cannot select individual areas but only whole slices of the data, which is not what I want. I searched on the web and consulted forums but could not solve the problem. Find enclosed the code; I sure hope sb. has an idea or a workaround for this.

Cheers Oliver

%%GridFit   
load('ASC')
% Generates mesh
Nodesx = min(ASC.x):5:max(ASC.x)
Nodesy = min(ASC.y):5:max(ASC.y)
% GridFit of data onto mesh
[zg,xg,yg] = gridfit(ASC.x,ASC.y,ASC.z,Nodesx,Nodesy, ...
               'smooth',0.01, ...      
               'interp','triangle', ...

               'extend','warning', ...
               'tilesize',inf);
%%Surf plot

% links the data sources
linkdata on

% Plot style options

zlim([-150 150]) % Defines scale for representing heights
colormap(jet(1000))
set(gca,'zticklabel',[],'ztick',[]); 
xlabel('x [cm]');ylabel('y [cm]')
cb = colorbar('vert');zlab = get(cb,'ylabel');
set(zlab,'String','Eelvation [cm]','fontsize',11); 
x1=get(gca,'position');x=get(cb,'Position');x(3)=0.01;
set(cb,'Position',x); set(gca,'position',x1)
set(gca,'fontsize',11)

% View options;
% view(2) % For brushing use Birdview
view([-35 60]); % View for final output

How you solve the problem? I am experiencing the same problem, I want to select specific points to brush but it selects the columns.

Thanks

Hey, I am facing the same problem. I also want to select a particular regrion of my surf plot but it selects all the columns. How did you solve it? Thanks
