how do i generate n numbers of static text boxes automatically? i.e. i dont have to go through guide in manually selecting each textbox.. coz here n is very large, in orders of 500s.. or is there any other text box type option available which can be generate automatically through a loop?

@Shree: why? What does a uitable not offer that an array of text boxes would.

在 MATLAB Online 中打开

TextItems = {'Hello', 'klaatu', 'MATLAB', 'cephaloid'};
for K = 1 : length(TextItems)
  texthandles(K) = uicontrol('Style', 'text', 'String', TextItems{K});
end

You would probably want to enhance this to control the position of the items.

Are you using GUIDE for your GUI?

What error are you encountering?

I am able to display values at any point on the image.however,I want to display the values at the exact co-ordinates obtained by getpts().if I set the position,the points do not display at the selected points but are far away or sometimes nowhere close to the initial coordinate.kindly help

It turns out that getpts returns data units. uicontrol() position is never data units.

Install https://www.mathworks.com/matlabcentral/fileexchange/10656-data-space-to-figure-units-conversion

ax = gca;            %or better yet, specific axes already created
[x y] = getpts(ax);
if isempty(x); return; end    %no points chosen
[xf, yf] = ds2nfu(ax, x, y);
for k = 1 : length(TextItems)
    texthandles(k) = uicontrol('Style', 'text', 'String', TextItems{K}, 'Units', 'normal');
end
set(texthandles, 'Position', [xf(1) yf(1) 15 15]);
handles.texthandles = texthandles;
guidata(hObject, handles);

Note that this would set all of the uicontrols to the same location, namely the location of the first point.

If you wanted to set one uicontrol style text for each point, then you need to specify what you want to have happen if there is a different number of points returned than there are text items.

Could you explain further why you want to create uicontrol style text for these, rather than creating text() objects or datatips ? uicontrol are not part of the axes, and so the uicontrol would stay exactly where they were if you were to zoom or pan or resize the axes without resizing the figure.

Which folder do I place the codes.do I put in bin?

Walter Roberson 2019-4-19

The question I was answering was for creating static text boxes automatically. That is something you might do if you are creating a user interface. It is not something you would do to label coordinates in a plot. uicontrol() are for user interface purposes; you would use text() to label nodes.

Use the Add-On Explorer to install that contribution and the explorer will automatically download and install it for you. Get Add-Ons, search for ds2nfu, click on the one marked as being by Michelle Hirsch, click to Add from GitHub, Ok downloading outside source.

Yes I'm using it to create a user interface.the add-on explorer appears not to work with R2015a

In that case click on the Download from GitHub button in the link I posted, and download the .zip file. Unzip it into any convenient unused directory that is not underneath where MATLAB itself is installed. Once it is unzipped, use pathtool to add the directory you installed into to your path.

I'm glad for your assistance.atleast the axes has maintained a region (0,0) to (1,1).is there a way I can force the image to stick to same region that is (0,0) to (1,1)?kindly
