How to change the format of the numbers displayed on in a MATLAB plot?

This is normal matlab photo plot. its name is called toyExample.png (orginal photo). But When I made matlab plot , it is non-normal plot. big numbers display format. Its name photo called Figure 1. How to change Figure 1. photo to convert as toyExample.png in matlab ?

Answer 1

[John BG]

it would help a lot that you show the code, because the graphs have handles that you can change.

Is it possible for you to post here the code?

[Ibrahim Abbasov]

Yes, of course John BG. There are two matlab file . 1) plotToyExample.m 2) visualRF.m

You can to run (plotToyExample.m) in matlab software and who will see non-normal figure.1 Thanks for help John BG.

Answer 2

[Star Strider]

This is the problem (in the code for ‘visualRF.m’):

      % add text to tree
      text(Z(1),X(1),mheight+1,[num2str(treeID) ',' num2str(strength)],'HorizontalAlignment','left','FontSize',20);
      →                                   →                           SET THE FONT SIZE TO SOMETHING SMALLER → ↑

Does this solve your problem? If so, you can Accept my Answer.

[Ibrahim Abbasov]

My friend Star Strider, I am deeply grateful to you for help. But there is one problem. The problem is that,in (visualRF.m) in line number 172 (color = hsv2rgb([feaID/100,1,1]);) change to color = hsv2rgb([feaID/150,1,1]); there is only one problem. when İ run VisualRF.m file it gives error. In VisualRF.m gives result the erros (visualRF(forestStrength, treeSim, treeStrength, treeData, tree, initLength, hillWidth, maxHillHeight) Undefined function or variable 'forestStrength'. I can't solution this problem. Please examine test both (1) plotToyExample.m 2) visualRF.m matlab file. I believe that you, dear friend, you are going to solve this problem. I send matlab file VFR in winrar.

Best regards, İbrahim

[Star Strider]

My pleasure.

I have no idea what you are doing, do I cannot specifically help with the code.

Please run the ‘plotToyExample.m’ file and see how it calls ‘VisualRF.m’. These files are written as functions, so the variables will not appear in your ‘Workspace’ browser. If you want to know the values of the variables, including the results of the calculations, remove the semicolon (;) from the end of the line that defines or assigns each one.

To begin, define:

forestStrength = 0.541292;

That may not be correct for your data, but it will get you started.

Then, when you use ‘VisualRF.m’ with your data, start with the other default arguments ‘plotToyExample.m’ uses, unless they are specifically different for your data.

Remember, that because of the way ‘VisualRF.m’ is written, you have to provide all the arguments. There appear to me to be no ‘built-in’ default options, so you have to specify all of them.

Please read all the documentation for your functions. It will tell you more than I can about them and how to use them correctly.

[Ibrahim Abbasov]

My friend, My idea is that, these matlab files don't give erros. But When İ run (plotToyExample.m) matlab file,an error does not happen. Please look to photo (plot example result .png)and (photo Figure 1a).

But When I run (VisualRF.m) matlab file only there is one error. Please look to photo (VisualRF errors.png) Everything is normal.But How do I solve this error ? (Undefined function or variable 'forestStrength'.)

[Star Strider]

As I wrote previously, you have to define all the arguments to ‘Visual RF.m’ in the line you call it. All the variables must exist in your workspace in order to be passed to the function.

This is the same problem you mentioned earlier, and my reply must be the same as well. See the documentation for Function Basics to understand MATLAB functions and how to work with them.

Please read the documentation for the function. If you have questions about the file or how to use it, contact the author of the file.

[Ibrahim Abbasov]

Star Strider, İ sent message to the author email yesterday. Still no answer from the author. I can't do patient. In addition to, how to work with Function Basic, the information is not satisfactory in about Function Basic.

[Star Strider]

These are the holidays, so the author may reply in early January 2017 at the earliest.

The ‘Function Basics’ reference is so you will understand how to use functions in MATLAB. You have to provide values for all the input arguments to ‘VisualRF.m’. Please look carefully through the code in ‘plotToyExample.m’ to understand how to use ‘VisualRF.m’ correctly.

[Ibrahim Abbasov]

I hope the author will respond as soon as possible. I'll try again. For more information, thank you for helping Star Strider.

[Star Strider]

My pleasure.

Answer 3

[John BG]

1.

in function getTree

      % add text to tree
      text(Z(1),X(1),mheight+1,[num2str(treeID) ',' num2str(strength)],'HorizontalAlignment','left','FontSize',10);

change FontSize to for instance 10

2.

I changed the field 'Color' to fixed 'red', in function getBinBranches, line

      line([[leftStartPos(3); leftEndPos(3)],[rightStartPos(3); rightEndPos(3)]],[[leftStartPos(1); leftEndPos(1)],[rightStartPos(1); rightEndPos(1)]], [[leftStartPos(2); leftEndPos(2)],[rightStartPos(2); rightEndPos(2)]], 'LineWidth', width, 'Color', 'red');

and ctrl+R

%     feaID = bin(id,2);
%     color = hsv2rgb([feaID/100,1,1]);

to have your code running, otherwise I was getting the following errors

Placing tree 1 at position (86  51)
Error using hsv2rgb (line 65)
Valid colormaps cannot have values outside the range [0,1].
Error in visualRF>getBinBranches (line 172)
    color = hsv2rgb([feaID/100,1,1]);
Error in visualRF>getTree (line 119)
    [~,mheight] = getBinBranches(initPos, initDir, initLength, treeData, nodeID);
Error in visualRF>createForest (line 101)
        getTree(position, ground(position(1), position(2)), treeData{t}, t,
        treeStrength(t), initLength);
Error in visualRF (line 82)
    createForest(ground, treeData, treePositions, treeStrength, tree, initLength);
Error in plt_Example (line 24)
    visualRF(forestStrength, treeSim, treeStrength, treeData, tree, initLength,
    hillWidth, maxHillHeight);

3. If you want to change the size of the axis tags, the [0 10 20 ..] just after plot add something like

ax=gca

and the you can change the size of that text too with for instance

ax.FontSize=20

My friend John BG, I am deeply grateful to you for help. But there is one problem. The problem is that,in (visualRF.m) in line number 172 (color = hsv2rgb([feaID/100,1,1]);) change to color = hsv2rgb([feaID/150,1,1]); there is only one problem. when İ run VisualRF.m file it gives error. In VisualRF.m gives result the erros (visualRF(forestStrength, treeSim, treeStrength, treeData, tree, initLength, hillWidth, maxHillHeight) Undefined function or variable 'forestStrength'. I can't solution this problem. Please examine test both (1) plotToyExample.m 2) visualRF.m matlab file. I believe that you, dear friend, you are going to solve this problem. I send matlab file VFR in winrar.

Best regards, İbrahim

[John BG]

try now with the files attached to this comment quick fix:

1.

in visualRF, te command line()

line([[leftStartPos(3); leftEndPos(3)],[rightStartPos(3); rightEndPos(3)]],[[leftStartPos(1); leftEndPos(1)],[rightStartPos(1); rightEndPos(1)]], [[leftStartPos(2); leftEndPos(2)],[rightStartPos(2); rightEndPos(2)]], 'LineWidth', width, 'Color', 'red');

the field color set to constant 'red'

2. removed (left as comments, ctrl+R) the previous lines

    % feaID = bin(id,2);
    % color = hsv2rgb([feaID/100,1,1]);

this is a quick fix only, but it solves the error you mention, doesn't it?

[Ibrahim Abbasov]

Matlab codes, as you wrote me, I made the same kind of in VisualRF file. I already have changed in VisualRF file. But there is a problem When I run VisualFR. I 'll show results to you. 1) When I run (plotToyExample.m) file, There is nothing error. Please Look at photo (PlotToyExample) but I run VisualRF matlab file gives one error. Please look at the VisualRF error photo. In VisualRF matlab file gives erros with red sentences as (Undefined function or variable 'forestStrength'.) How do I solve it ?

[John BG]

I just tried plotToyExample.m the one above your last comment and there is no error. VisualRF.m is a support function to plotToyExample.m

the function forestStrength.m is defined in plotToyExample.m so if you try to call VisualRF.m directly there is an error because MATLAB doesn't reach from VisualRF.m to plotToyExample.m ony from plotToyExample.m to VisualRF.m

I have put VisualRF.m inside plotToyExample.m this way you don't get any error, try the attached file here plotToyExample2.m

[Ibrahim Abbasov]

For help, I would like to thank you. My friend, Everything is perfect. When I put VisualRF.m inside plotToyExample.m, the error did not occur. İt works. I congratulate to you on the upcoming new year holiday. Happy new year.

[John BG]
