Hello,

Is it possible to assign scatter plots in a structure array which can then be recalled individually?

I currently have the following line:

cell_data(i).visual = scatter3(a(:,1), a(:,2), a(:,3),50, 'fill')

However if I try to recall any individual plot I just receive a number...

Kind regards,

Tom

In the structure array there is an associated matrix where the first column is x positions, second column y, and third column z.:

cell_data(i).positions

    0.5288    0.2819    1.4861
   -0.3424    1.4281   -0.7547
    1.3766   -0.5107   -0.7808
   -1.1564   -1.0787   -0.0540

It'd be useful if I could call up the 3D scatter plot for each entry in the structure array, is this possible?

You assign values to cell_data(i).positions in your code? Is it the values of a?

"call up the 3D scatter plot". Do you mean make the plot visible; bring it to the top?

Try this with the [Run and Advance] button

    jj = 1;
    a  = magic( 3 );
    figure 
    cell_data(jj).visual = scatter3(a(:,1), a(:,2), a(:,3), 50, 'fill');
    jj = 2;
    a  = randi( 6, [3,3] );
    figure % create new figure; avoid overwriting 
    cell_data(jj).visual = scatter3(a(:,1), a(:,2), a(:,3), 50, 'fill');
    get( cell_data(jj).visual, 'Type' )
    fh  = ancestor( cell_data(jj).visual, 'figure' );
    figure( fh )
