MATLAB: Add text/ annotation to table in figure window

annotation;MATLABtext;uitable

Hi everyone,

I am creating a figure with three tables A,B,C like

f = figure
uitable('Parent',f,'Data',A{:,:},'ColumnName',A.Properties.VariableNames,'RowName',A.Properties.RowNames,'Units', 'Normalized', 'Position',[0, 0, 1, 1/3])
uitable('Parent',f,'Data',B{:,:},'ColumnName',B.Properties.VariableNames,'RowName',B.Properties.RowNames,'Units', 'Normalized', 'Position',[0, 1/3, 1, 1/3])
uitable('Parent',f,'Data',C{:,:},'ColumnName',C.Properties.VariableNames,'RowName',C.Properties.RowNames,'Units', 'Normalized', 'Position',[0, 2/3, 1, 1/3])

Now I want to add some kind of title to each table. I tried to use 'text' and 'annotation' but those functions seem to work for graph plots only. Is there a way to add text or even titles to tables displayed in a figure window?

As per my knowledge, text requires an axis as a parent. If its not present, an axis object will automatically get created.

In your case, you will have to use the uicontrol with Style as text to get the desired result.

Please refer the following documentation for example usage of this command:

https://www.mathworks.com/help/matlab/ref/uicontrol.html#mw_90b32567-d19c-44e3-95d3-95fd2465a030

The following documentation page for more information about controlling the appearance of the uicontrols:

MATLAB: UITable does not resize with rest of figure window

For any figure component to automatically resize, you must change its "Units" property to "normalized."

<https://www.mathworks.com/help/matlab/ref/matlab.ui.control.table-properties.html#buiu91u-1_sep_shared-Units>

The default position units are in "pixels" which obviously don't scale with the figure itself. Once you have change "Units" to "normalized, you can reset the "Position" property as appropriate.

MATLAB: How to display a MATLAB table in a figure

You can either use "uitable" or a more complicated series of commands depending on how you want the table to look.

For example, let us assume you have a table defined by the following code:

LastName = {'Smith';'Johnson';'Williams';'Jones';'Brown'};
Age = [38;43;38;40;49];
Height = [71;69;64;67;64];
Weight = [176;163;131;133;119];
T = table(Age,Height,Weight,'RowNames',LastName);

1.) If you want the table to have adjustable-width columns and a more stylized look, execute the following "uitable" command to display the table "T" in a figure:

uitable('Data',T{:,:},'ColumnName',T.Properties.VariableNames,...
    'RowName',T.Properties.RowNames,'Units', 'Normalized', 'Position',[0, 0, 1, 1]);

You can refer to the following documentation link for more information on "uitable":

https://www.mathworks.com/help/matlab/ref/uitable.html

2.) If you want the table to look very similar to how it looks when outputted in the MATLAB command window, execute the following series of commands to display the table "T" in a figure:

% Get the table in string form.
TString = evalc('disp(T)');
% Use TeX Markup for bold formatting and underscores.
TString = strrep(TString,'<strong>','\bf');
TString = strrep(TString,'</strong>','\rm');
TString = strrep(TString,'_','\_');
% Get a fixed-width font.
FixedWidth = get(0,'FixedWidthFontName');
% Output the table using the annotation command.
annotation(gcf,'Textbox','String',TString,'Interpreter','Tex',...
    'FontName',FixedWidth,'Units','Normalized','Position',[0 0 1 1]);
