Sep 5, 2016 · I have an Nx3 array which stores the values in N coordinates. The first and second column correspond to x and y coordinate respectively, and the third column represents the value at that coordinates. I want to plot a 2D intensity plot, what's the best way to do it?

Jul 31, 2019 · If calories is 2D, then you should use something like plt.contourf(),plt.imshow(), or plt.pcolormesh(). You might want to consider a scatter plot like afb mentioned if all your arrays have the same shape.

May 7, 2013 · The data for an intensity graph in LabVIEW is a 2D array of double precision floating point values (or doubles for short). For an intensity graph, every value corresponds to a color, where a scale on the graph is used to define colors over a range of values.

May 17, 2021 · I have 3 , 100x1 array X=100x1 all points on X axis Y=100x1 all points on Y axis Z=100x1 ranging from [0 to 1] denoting color intensity how to pot 2d image X,Y and use Z as colormap for ea...

I am currently trying to create a simple GUI based on matplotlib(Python 2.7). My aim is to plot a 2d intensity map and look at the x and y slices with a user controlled curser. It already worked ou...

May 30, 2024 · Please refer to the code snippet below, which outlines one such approach for plotting a 2D map. This method utilizes `x` and `y` as coordinates, with `z` representing intensity. The snippet also includes code to interpolate the `z` values across the grid.

Jun 3, 2024 · To plot a 2D intensity plot in matplotlib, you can use the imshow function from the matplotlib.pyplot module. First, import the necessary libraries by using import matplotlib.pyplot as plt. Then, create a 2D array of intensity values that you want to plot. You can use a NumPy array for this purpose.

Mar 22, 2007 · I'm trying to make an intensity plot as a function of x and y positions.... I have a scanning stage that gives me the positions and I am measuring.

May 4, 2020 · So in short, you want: myColorMap = hsv (256); % Create a colormap. colormap (gca, myColorMap); % Now apply the colormap. You can also pass the colormap directly into imshow () and skip calling the colormap () function if you want. See this full demo and study it: % Create a colormap. % Display image with that colormap.

Feb 9, 2018 · I have defined a surface under the data sets tab in results and now I want to plot the intensity distribution at the working plane as a contour plot. However, when I add a 2d plotting group with a surface plot and try to chose gop.I as the variable to plot, I get an error message:
