#MATLAB 2012 PLOT COLORS HOW TO#
#MATLAB 2012 PLOT COLORS CODE#

In a different post, I explain how to freeze colors for different colormaps on the same figure. Incorrect: colorbar('YTick',log(Contours),'YTickLabel',Contours,'FontSize',12) Use: colorbar('YTick',log(Contours),'YTickLabel',Contours) Ĭaxis(log()) Ĥ) Make sure the last thing you do is set the Ticks! I've noticed if you have any other commands after this in the colorbar command, it reverts back to something funky.Įxample: Correct: colorbar('FontSize',12,'YTick',log(Contours),'YTickLabel',Contours) contourf(log(Data(:,:)),log(Contours)) ģ) Define the tick marks on your colorbar The last step is to make the colorbar show the correct data. If you’ve been checking out Trendy at all, you’ve probably seen Hugo Carr ‘s.

But if you look at his code, you can see how he easily changed the colors in his plot command.

Also be sure to take the log of your defined contours so they show up in the right spot. In Ned Gulley’s trend Temperatures in Anchorage and Honolulu, notice that he has a similar plot charting two different pieces of data. How to draw three dimenstional plots in MATLAB MATLAB 3D plot examples explained with code and syntax for Mesh, Surface Ribbon, Contour and Slice.

MATLAB PLot Colors code you can copy paste: x 0:0.01:10 y1 sin (2x) y22.cos (2. If the coordinates are not given, it will use the indices of the matrix as coordinates. I would like to mantain different colors for each part of the single bars, but when I plot the figure the bars turn into the same color, even if still. MATLAB code: Here is MATLAB code you can write to plot the graph for the function of f (x) and its d/dx (f (x)). To plot the color map of the given matrix, you can use the meshc() function, which plots the color map of the variable on a given x and y-axis and adds the contour plot under the mesh plot. Let’s go ahead a plot the following code. The values are defined with a color map ranging from 0-4 such that for each x value, the values are plotted along each of the sub-parts of y-axis according to the color code. For the plot here, I used: Contours= Ģ) Plot your Data Using imagesc, contourf, or some other function, plot the log of your data. Plot a Color Map Using the meshc() Function in MATLAB. Just like it is to change the color of your plot in Matlab, the same goes for changing the line style, increasing the thickness of the line or some other aspect of it. I want to plot a 2d plot in which x-axis represent the stimulus number, y- axis is subdivided into 8 sub-parts and the scale of each sub-part is from 0-4. A quick google search on how to make logarithmic contour plots and logarithmic color-bars yielded some unhelpful results, so I thought I'd give a quick post here.ġ) Define Your Contours Define where you'd like contours. A lot of my data ranges orders of magnitude, and can be very hard to depict using standard MATLAB functions like imagesc, contourf, contour, etc.
