First, load in the image, the generate (x,y) pairs for each intensity in the image. This is done with meshgrid. Once you do this, use scatter to plot each point assuming z = 0 and make the colour of each point the actual intensity seen at the image coordinate. However, you will only see this in a 2D perspective as scatter is naturally 2D.The first row of pixels is normally at the top of an image. By default, the IMAGE and IMAGESC functions invert the y-axis direction when the image is displayed on an axes by setting the 'YDir' property to 'reverse.' To invert the y-axis direction, set the 'YDir' property to 'normal', as follows:

More Answers (1) "axis ydirection controls the placement of the coordinate system origin and the direction of increasing y values. Set ydirection to ij to place the origin at the upper left corner of the axes. The y values increase from top to bottom. Set ydirection to xy to place the origin at the lower left corner.F: the frequencies you want the spectrum evaluated at. fs: the sampling frequency of your signal. Then plot the spectrogram with: subplot(313); imagesc( T, F, log(S) ); %plot the log spectrum. set(gca,'YDir', 'normal'); % flip the Y Axis so lower frequencies are at the bottom. Note: The quality and interpretability of a spectrogram depends on ...

3. You can use the function flip to flip any array along one axis: Aa = flip(A,2); This will work for both a gray-scale and an RGB image. This is equivalent to the following indexing expression for a 3D array (such as an RGB image): Aa = A(:,end:-1:1,:); Tip: If you are going to write a loop, always make the inner loop the one that loops over ...In order to mesure the flame length, I have to plot axis.

So,the main problem here is how to use a definite vector whose value are corresponding to the image axis and has the same size with the image rows. here are my code and results, x=1:n;y=linspace (0,fmax,m)'; y=1./y; y=y (2:end); figure ('color', [1 1 1]); imagesc (x,y,v); you can change the ...The problem is, I presume, that although your image shows 15 numbers along in each axes, the total size of your image in pixels is 450 x 450 - and this is what imagesc is using. So, what you really have is an image with 15 x 15 blocks of 30 x 30 pixels. You can set the axes ticks and labels manually using XTick and XTickLabel: Best Answer. After displaying an image with the IMAGESC function, you can change the axis so it is decreasing from top to bottom. For example, load clownX = flipud(X);imagesc(X)colormap( map )axis( 'xy')

The first row of pixels is normally at the top of an image. By default, the IMAGE and IMAGESC functions invert the y-axis direction when the image is displayed on an axes by setting the 'YDir' property to 'reverse.' To invert the y-axis direction, set the 'YDir' property to 'normal', as follows:hold on. % Now you can convert from datetime to numerics using ruler2num. x = ruler2num (times, gca ().XAxis); % Now pass the double data to imagesc. im=imagesc (x,yvals,colors); % Finally, because hold was on, you need to manually set the limits (which. % is normally done for you by imagesc) and turn on the box.Link. If you want rotation along the y axis instead of the z axis, then the image will appear foreshortened (narrower), thus the width is reduced.
