Hi

I'm using text to plot the text in a user interface figure (x,y,str). I was unable to see the original text message since they overlapped.

Can someone please tell me how to prevent the words from overlapping?

Thank you!

Thanks Adam,

I am NOT clear, what is the meaning of position of Text. It can be

Case -1
||Time        || Message
|00.00.00.001 | str1 str2 % Line 1 with Dropdown1 cell data & Dropdown2 CellData
Case -2
||Time        || Message
|00.00.00.001 | str1                  % Line 1
|00.00.00.001 | str2                  % Line 2

How do i postion string in a designated postion ?

I want text print to be like Case -1/ since my text data is from same line and NOT next line but they are overlapped , I want the text overlap data (from each Dropdown menu) to be removed

Probably i can think of below example . Case 2 works better than other cases!

Can you please help me with better explanation for my implementation needs?

Thank you!

   clc;close all;    
   x = [1:5] ;
   y = [1:5] ;
   bit_position = 2;
   str1 = ['one  '];
   str2 = ['two  '];
   str3 = ['three'];
   str4 = ['four '];
   str5 = ['five '];
   str = ['One',...
       'Two',...
       'Three',...
       'Four',...
       'Five'];
   for i = 1:numel(x)
       plot(x,y);
       if isequal(bit_position,1)
           subplot(3,1,1);
           text(x(i),y(i),str(i), 'position',[i/numel(x) i/numel(x)]);
           xlabel('xTicks');ylabel('MSG');
       elseif isequal(bit_position,2)
           subplot(3,1,2);
           text(x(1),y(1),str1,'position',[1 10]);
           text(x(2),y(2),str2,'position',[1 10]);
           text(x(3),y(3),str3,'position',[1 10]);
           text(x(4),y(4),str4,'position',[1 10]);
           text(x(5),y(5),str5,'position',[1 10]);
           xlabel('xTicks');ylabel('MSG');
       elseif isequal(bit_position,3)
           subplot(3,1,3);
           text(x(1:numel(x)),y(1:numel(x)),str(1:numel(x)),'position',[i/numel(x) i/numel(x)]);
           % text(x(1:numel(x)),y(1:numel(x)),str(1:numel(x)),'position',[1 10]);
           xlabel('xTicks');ylabel('MSG');
       end
   end

I don't have a mental image of what text you want to plot and where the text should go in the figure.

I want to plot text data against time of occurance/Time vs message. I have text data point on same time.

I dont' understand why you're plotting text at certain locations in the plot.

I am not plotting text to a location. The text('position',[]) - is not used. This is an issue for now.

I don't understand what parts of the text should be included on the plot.

I want to plot , Time vs Message.

I don't understand what determines the (x,y) coordinates of the text.

x-axsis = time[WeirdDuration]/row,
y-axis = message[log_autoserv1_autoserv,Sublog_autoserv1_autoserv,Message_autoserv1_autoserv]/column

WeirdDuration    log_autoserv1_autoserv    Sublog_autoserv1_autoserv                                          Message_autoserv1_autoserv                                      
_____________    ______________________    _________________________    ______________________________________________________________________________________________________
00:00:00.000           {'INFO |'}              {'pidfile:0016|'}        {'Logged pid 4404 to /tmp/test_that_results_hatch_QIZGx2/results-07-firmware_Mosys/.autoserv_execute'}

plot(x,y,str) ==> plot(x,y,str,'position',[ ]) , Note 'position',[ ] is missing

hTxt1 = text(app.axis,WeirdDuration,log_autoserv1_autoserv) ==> text(00:00:00.000,{'INFO |'})

hTxt2 = text(app.axis,WeirdDuration,Sublog_autoserv1_autoserv) ==> text(00:00:00.000,{'pidfile:0016|'})

hTxt3 = text(app.axis,WeirdDuration, Message_autoserv1_autoserv) ==> text(00:00:00.000,{'Logged pid 4404 to /tmp/test_that_results_hatch_QIZGx2/results-07-firmware_Mosys/.autoserv_execute'})

OK, I will take time to understand text() function and file exchange,

Thank you!

1) I'm not sure what I'm supposed to do with the app.

2) "The text('position',[]) - is not used. This is an issue for now." -- I don't understand this. text() is a function and the (x,y) position inputs are required. So I don't know what it means that the text position is not used.

3) "I want to plot , Time vs Message." I understand that time is along the x axis but what are the units of "message" along the y axis?

4) "I will take time to understand text() function " I think it may take an hour or two. But keep in mind this discussion has continued for ~2 days so reading through the documentation and truely understanding the inputs to the text() function will be faster.

I'd really like to help but the problem is still unclear.

Check out this example below and tell me if it's helpful or related to what you want to do.

fig = figure();
ax = axes(fig); 
textSamples = {'First Row', 'Second Row', 'Third Row'}; 
x = 1:3
y = 1:3; 
plot(ax, x, y, 'bo')
hold(ax, 'on')
% Example of text()
text(ax, x+.05, y, textSamples,'HorizontalAlignment', 'Left')
xlim([0,4])
ylim([0,4])
% example of labelpoints()
labelpoints(x,y,textSamples,'N','color','b') % N is for North

Hi Adam,

I understood the issue more from your figure. Thank you very much!

Let's say

- x-+.25 means we are shifting the text location by 0.25 units on time scale(x -co ordinate).

- y-+.25 means we are shifting the text location by 0.25 units on Index scale(y -co ordinate)

That means co ordinates will changes.

In case , if we use marker to indicate location and shift the text, then the problem straring " how long one can define text position shift space" ? There can be possibility of additional Text in waiting to surface on the figure

In -fact , I was asking on the same axis (x,y) points I had the multiple text data.

I don't know - how to define the concept....

K>> text(app.UIAxes,h,range,s_DropDown1(range),range,'VerticalAlignment','bottom',"FontSize",12,    "Color",rand(1,3));
K>> text(app.UIAxes,h+0.25,range,s_DropDown1(range),range,'VerticalAlignment','bottom',"FontSize",12,    "Color",rand(1,3))
K>> text(app.UIAxes,h,range+0.25,s_DropDown1(range),range,'VerticalAlignment','bottom',"FontSize",12,    "Color",rand(1,3))
K>> text(app.UIAxes,h,range-0.25,s_DropDown1(range),range,'VerticalAlignment','bottom',"FontSize",12,    "Color",rand(1,3))
K>> text(app.UIAxes,h-0.25,range,s_DropDown1(range),range,'VerticalAlignment','bottom',"FontSize",12,    "Color",rand(1,3))

Some how- I don't see accept answer option!

That's because this discussion has been in the comments section. I just added an answer that summarizes the solution.

Here are two ways to control the position of text in a plot

Use Matlab's text() function

The HorizontalAlignment and VerticalAlignment properties control the text position relative to the coordinate.

fig = figure();
ax = axes(fig); 
textSamples = {'First Row', 'Second Row', 'Third Row'}; 
x = 1:3
y = 1:3; 
plot(ax, x, y, 'bo')
hold(ax, 'on')
% Example of text()
text(ax, x+.05, y, textSamples,'HorizontalAlignment', 'Center', 'VerticalAlignment', 'Bottom')
xlim([0,4])
ylim([0,4])
