Hello i would like to have 3 circles on the same image in one figure Also i dispay a text but now the text is all at the same pixel maybe i could use a variable which counts some pixels down for each circle it will display? How can i do this? Here is my code:

%Image 
I = imread ('bonds_image.jpg');
% excel File einlesen/ auswählen
[fileName,dirName]=uigetfile('T_APC_RUNKEYNUMBER_test.xlsx');
[~,~,rawData] = xlsread(fullfile(dirName,fileName));
   %
I_with_circle = insertShape ( I , 'circle', [951 332 20] , 'LineWidth' , 5 , 'Color' , 'red');
I_with_circle_and_text =  insertText(I_with_circle, [470, 12], 'Bond 1 Draht 1 Bottom', 'FontSize', 18, 'BoxColor', 'red', 'TextColor', 'black');
imshow(I_with_circle_and_text);
   %
I_with_circle = insertShape ( I , 'circle', [664 331 20] , 'LineWidth' , 5 , 'Color' , 'red');
I_with_circle_and_text =  insertText(I_with_circle, [470, 12], 'Bond 1 Draht 9 Bottom', 'FontSize', 18, 'BoxColor', 'red', 'TextColor', 'black');
imshow(I_with_circle_and_text);
   % 
  I_with_circle = insertShape ( I , 'circle', [267 331 20] , 'LineWidth' , 5 , 'Color' , 'red');
I_with_circle_and_text =  insertText(I_with_circle, [470, 12], 'Bond 1 Draht 19 Bottom', 'FontSize', 18, 'BoxColor', 'red', 'TextColor', 'black');
imshow(I_with_circle_and_text);

Hi, For displaying all three circles at the same time, since they are all the same circle, just in different places, you actually only need one call for this.

I_with_circle = insertShape (I, 'circle', [951 332 20;664 331 20; 267 331 20], 'LineWidth', 5 , 'Color', 'red');
I_with_circle_and_text =  insertText(I_with_circle, [470, 12], 'Bond 1 Draht 1 Bottom', 'FontSize', 18, 'BoxColor', 'red', 'TextColor', 'black');
imshow(I_with_circle_and_text);

As far as displaying the boxes separately, you can use the following (you can put in whatever positions you want).

position = [470,12; 470, 100; 470, 188]; 
box_color = {'red','red','red'};
text={'Bond 1 Draht 1 Bottom' 'Bond 1 Draht 9 Bottom' 'Bond 1 Draht 19 Bottom'};
I_with_circle_and_text =  insertText(I_with_circle, position,text, 'FontSize', 18, 'BoxColor', box_color, 'TextColor', 'black');
imshow(I_with_circle_and_text);
