How to add a variables name into a datatip

Hello,

I have measured some points and assigned names to them. Therefore I created a table "points" with the columns Name, X, Y, Z.

For example:

'L0.bag'	0.00366596578951730	-0.179678423557261	0.134501933438593
'L1.bag'	0.00672638008503305	0.243144532604341	-0.0422136590497351

Now I plot them with

scatter3(points.x, points.y, points.z, '*')

In order to compare different measurements I need to know which point is originally which.

Is there a way I can display the related name when I create a datatip?

I used this code in a different context but it does not seem to work here

dcm=datacursormode(fh);
datacursormode on
set(dcm, 'updatefcn',{@GeoDataTip, name })

This demo consists of three 3D scatter points with labels 'a','b','c'.

% Create demo data
T = table({'a';'b';'c'},[1;2;3], [2;1;3], [3;2;1], ...
    'VariableNames', {'Label','x','y','z'}) 

T = 3×4 table
    Label    x    y    z
    _____    _    _    _

    {'a'}    1    2    3
    {'b'}    2    1    2
    {'c'}    3    3    1

% Plot 3D scatter
figure()
h = scatter3(T.x, T.y, T.z);

% Add labels
h.DataTipTemplate.DataTipRows(end+1) = dataTipTextRow('Label',T.Label);

% Create a datatip to show results
datatip(h);

It worked perfectly!

Thank you very much for the good explanation and the example
