Aug 27, 2014 · I'm trying to plot a 2 dimensional signal on a specific plane in a 3d model. I have the matrix: xyzp (nx3) that contains all the points which are closest to the plane (e.g. when the plane is in t...
How can I plot a single 2-D curve onto a colormap in Matlab?
Jun 28, 2019 · I have created a smooth color gradient 2-D contour plot with existing compiled data in Matlab. I have an x-axis, y-axis, and z-data contour plotted as a colormap. My goal is to plot a 2-D curve onto the colormap, representing a single z-data value, but I don't know how. Does anyone know how to plot a 2-D curve onto a 3-D colormap?
How to plot a smooth 2D color plot for z = f (x, y)
May 28, 2015 · I am trying to plot 2D field data using matplotlib. So basically I want something similar to this: In my actual case I have data stored in a file on my harddrive. However for simplicity consider the function z = f(x, y). I want a smooth 2D plot where z is visualised using color. I managed the plotting with the following lines of code:

How to plot a 3-column matrix as a color map in MATLAB?
I want to convert this matrix into a human-viewable plot like a color plot (2D or 3D), how can I do this? 3D can be something like this : or just the 2-D version of this (looking from top z-axis).
matplotlib - 2D colormap in Python - Stack Overflow
May 23, 2020 · I have a 2d vector (x,y) and I need to find a 2D colormap that maps these coordinates to a smooth colormap. The color code will depend only on the (x,y) value. For instance, white around the center, more red as we go to the northeast, more blue as we go the southeast, more green as we go to the northwest,
matlab - How to create a colormap based on value? - Stack Overflow
