MATLAB: How to plot a graph along with axes graph

graphMATLABplotplotting

I want to creat a plot like this. is there any function for this? How to make it?

Just build custom-placed subplot() axes...something like

I=imread('ngc6543a.jpg');           % just an image to use later...
figure
pos1=[0.1 0.3 0.2 0.6];             % guess at position vector for first axes
pos2=[pos1(1)+pos1(3)+0.05 pos1(2) 0.9-(pos1(1)+pos1(3))-0.05 pos1(4)];  % adjust for second
pos3=[pos2(1) 0.1 pos2(3) pos2(2)-0.15];                                 % and for third..
hAx(1)=subplot('Position',pos1); box on
hAx(2)=subplot('Position',pos2); box on
hAx(3)=subplot('Position',pos3); box on
hAx(1).YScale='log';
hAx(1).YLim=[0.10 35];
hAx(1).YTick=2.^[0:8]/8;
hAx(3).YLim=[-100 100]; hAx(3).XLim=[0 30];
image(hAx(2),I)
hAx(2).XTick=[];hAx(2).YTick=[];

resulted in

Hadn't yet added the colorbar and looks like could have made the width for hAx(1) somewhat smaller which will leave a little more room for it.

Basic form for what asked for, though, it would appear...

ADDENDUM:

NB: subplot is unneeded here; just use axes. I had initially tried to see if could smoosh together some but it only works to merge contiquous numbers, but then didn't change the call...

MATLAB: Set Image Axis as Primary Axis

Following example show how to synchronize the image axis with the MATLAB plot axis

im = imread('image.jpeg');
fig = figure();
h = imshow(im);
ax_img = gca;
ax_plot = axes();
hold(ax_plot);
ax_plot.Color = 'none';
ax_plot.Position = [0.183 0.158 0.678 0.778]; % bit of trial and error
ax_plot.XLim = [1 100];
ax_plot.YLim = [0.005 1];
ax_plot.XScale = 'log';
ax_plot.YScale = 'log';
% Example: give values in image coordinates
plot(ax_plot, [1 5 10 50 100], [0.005, 0.05, 0.1, 0.5, 1], 'r', 'LineWidth', 2);
ax_plot.Visible = 'off';

MATLAB: How to format tick labels before R2016b

For MATLAB R2015b and newer versions:

This functionality was added to MATLAB graphics system in R2015b. The following code shows the simplest way to achieve this:

plot(1:10);
ax = gca;
ax.XAxis.TickLabelFormat = '%,.1f';

For more information on individual axis customizations, please refer to the following blog:

https://blogs.mathworks.com/loren/2015/09/16/individual-axis-customization/

For MATLAB R2015a and older versions:

You can use one of the following methods to format your tick labels:

1. Use the SPRINTF function to format your tick labels using the format of your choice then set the 'XTickLabel' or 'YTickLabel' property of the axis to use those strings as tick labels.

An example which demonstrates this is:

x=[1 1.53 4];
y=[1 2 3];
plot(x,y)
set(gca,'XTick',x)
set(gca,'XTickLabel',sprintf('%3.4f|',x))
set(gca,'YTick',y)
set(gca,'YTickLabel',sprintf('%+1.2f|',y))

For more information on the available formats, consult the documentation for the SPRINTF function. Also, consult the documentation for the XTickLabel in the 'Axes properties' section.

NOTE: for MATLAB R2014b and later you will have to use new line character instead of the | symbol. For instance, the following command will work for MATLAB R2014b and later.

set(gca,'XTickLabel',sprintf('%3.4f\n',x))

2. Use the STR2MAT function to create a use the tick labels of your choice. An example which demonstrates this is:

x=[1 1.53 4];
y=[1 2 3];
plot(x,y)
set(gca,'XTick',x)
set(gca,'XTickLabel',str2mat('1.00','1.530','2'))
set(gca,'YTick',y)
set(gca,'YTickLabel',str2mat('1.00','2.00','3.00'))

You can change the auto generated tick marks by first getting them using get(gca,'XTickLabel') followed by one of the two methods listed above.
