MATLAB: I am getting a colorbar with uniform color. I want there to be variations so the distribution makes sense.

colorbarcontourimageimshow

The P matrix varies from 1 to 2, however the returned figure shows one square with one uniform color. it would be a great help, if i could have a range of colors in that range(1 to 2) to show the distribution.

imshow(P,'InitialMagnification',2000)

colb = colorbar;

set(colb, 'ylim', [1 2])

Best Answer

imshow(P, [], 'InitialMagnification',2000)

MATLAB: Colormap, how to get the color of the sea

Try a program where you can easily get the RGB values of some color of blue that you like, like (r,g,b) = (rBlue, gBlue, bBlue). Then use linspace().

numColors = 256; % Good value for 24/32 bit displays.
oceanRed = 15;
oceanGreen = 127;
oceanBlue = 230;
myColorMap = [linspace(oceanRed, 255, numColors)'/255,...
  linspace(oceanGreen, 255, numColors)'/255,...
  linspace(oceanBlue, 255, numColors)'/255]
imshow('cameraman.tif');
colormap(gca, myColorMap);
colorbar

MATLAB: Visualizing 1D data with Color.

There are many different ways of doing this. It depends on how you want to visualize the data. E.g. as bars, as dots, as a 1xn surface, as a 1xn image.

If you want an image you could use the following for a vector "a":

a=rand(1,10); figure; imagesc(a); colormap(jet(numel(a))); colorbar;

Alternatively you could use the scatter function to plot as colored points. For the x coordinates you could use time and for y the speed and you can color the points according to speed e.g.:

n=10; t=1:n; a=rand(1,n); figure; scatter(t,a,50,a,'filled');colormap(jet(n)); colorbar;
