Jun 29, 2012 · I have a 2-D scatter plot and at the origin I want to display an image (not a colorful square, but an actual picture). Is there any way to do this? I also will be plotting a 3-D sphere in which I would like an image to be displayed at the origin as well.

I have a JPEG image of a 2D graph. The graph is intensity vs wavelength. I need to find the peaks in this graph and record the intensity and wavelength. I already know how to find the peaks in a plot. Does anyone know how to take this image and convert it into a dataset?

Dec 14, 2015 · Example: Image graph with special connectivity. Use a 3-by-3 connectivity matrix to create an image graph with 6-connected pixels. Each pixel is connected to its north, northeast, east, south, southwest, and west neighbors. conn = [0 1 1; 1 1 1; 1 1 0]; g = imageGraph([480 640],conn); plotImageGraph(g) axis([100 110 220 230])

Read a JPEG image file. Display the image. Create a surface plot. Then, add an image under the surface. image displays the image in the xy-plane. Over 8 examples of Images including changing color, size, log axes, and more in MATLAB.

Mar 16, 2011 · i have a jpeg image of a graph (a simple temperature vs time graph, non linear curve). is it possible to use matlab to process the image and then recreate the graph in matlab, out-putting the x and y coordinates of say 100 points along the curve?

Jun 30, 2022 · Plot the image using image or imagesc or some other image function that allows you to specify the x and y values of the image. That way you set the image coordinates to the data coordinates. Then just hold on and plot the data into the same axes.

Jul 16, 2014 · What I would like to do is plot an image of a graph (from say a pdf file or a scanned image). Next, I would like to overlay an axis on the graph in the image, and then plot data on that axis (over the image).

Apr 14, 2015 · I am looking for a function or code in matlab that i can import a image (jpeg,bmp...) that show a graph and extract the graph data from the image.

Feb 1, 2013 · To overlay plots on the image, using hold on followed by plot should work. An important part will be to have a sensible metric when displaying your image that allows you to place your overlays accurately.

Nov 16, 2015 · Image Graphs is a collection of several functions to make and visualize graphs based on pixel neighbor relationships in an image. The functions imageGraph and imageGraph3 make graphs containing one node for every pixel in an image.
