How can I change the distance between the axis title and the axis values in a 3D scatterplot in Plotly (Python)? Question: i have the following example code of a 3d Scatterplot in plotly and i want to place the x,y and z title with more distance to the axis. import plotly.graph_objects as go # …
Plotting a 3-dimensional superball shape in matplotlib Question: I’m trying to plot a 3D superball in python matplotlib, where a superball is defined as a general mathematical shape that can be used to describe rounded cubes using a shape parameter p, where for p = 1 the shape is equal to that of a sphere. …
Plotting surface and curve in 3D and a curve in xy-plane, all in the same plot Question: To illustrate an optimization problem, I want all of this in the same 3D plot: A surface. A curve in the xy-plane. A curve/path on the surface which marks out the points on the surface that lies directly …
make 3d numpy array using for loop in python Question: I have training data with 2 dimension. (200 results of 4 features) I proved 100 different applications with 10 repetition resulting 1000 csv files. I want to stack each csv results for machine learning. But I don’t know how. each of my csv files look …
Way to specify viewpoint distance in Matplotlib 3.6.3 3D Plots? Question: I am working on an animation of a 3D plot using mpl_toolkits.mplot3d (Matplotlib 3.6.3) and need to set the view distance. It seems that earlier versions of Matplotlib allowed the elevation, azimuth, and distance of the viewpoint "camera" to be set for 3D plots …
Converting a massive into a 3 dimensional bitmap Question: Problem I need this massive to serve as an input (for C based arduino). This is our massive from the example above in the required format: const byte bitmap[8][8] = { {0xFF, 0x81, 0x81, 0x81, 0x81, 0x81, 0x81, 0xFF}, {0x81, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, …
