Matplotlib can be used to do 3D plots.

Here is the Python code.
import matplotlib.pyplot as plt import rsPlot # required import to use 3d: from mpl_toolkits import mplot3d import numpy as np np.random.seed(12345) def randomRange1(n1, min1, max1): return (max1 - min1)*np.random.rand(n1) + min1 plot1 = rsPlot.plot("plot41-1") plot1.ax1 = plt.axes(projection="3d") fig1 = plot1.fig1 ax1 = plot1.ax1 ax1.set_xlabel("x domain") ax1.set_ylabel("y domain") ax1.set_zlabel("z range") n1 = 100 for m1, zlow1, zhigh1 in [("o", -50, -25), ("^", -30, -5)]: xs1 = randomRange1(n1, 23, 32) ys1 = randomRange1(n1, 0, 100) zs1 = randomRange1(n1, zlow1, zhigh1) ax1.scatter(xs1, ys1, zs1, marker=m1) plot1.save()

Here is the output of the Python code.

Matplotlib can be used for wire-frame plots.

Here is the Python code.
import matplotlib.pyplot as plt import rsPlot # required import to use 3d: from mpl_toolkits import mplot3d import numpy as np def fxy1(x1, y1): return np.sin(np.sqrt(x1*x1 + y1*y1)) plot1 = rsPlot.plot("plot41-2") plot1.ax1 = plt.axes(projection="3d") fig1 = plot1.fig1 ax1 = plot1.ax1 ax1.set_xlabel("x") ax1.set_ylabel("y") ax1.set_zlabel("z") xData1 = np.linspace(-5, 5, 20) yData1 = np.linspace(-5, 5, 20) xMesh1, yMesh1 = np.meshgrid(xData1,yData1) zData1 = fxy1(xMesh1, yMesh1) ax1.plot_wireframe(xMesh1, yMesh1, zData1, color="#000099") for pos1 in range(0, 7): angle1 = 15*pos1 print("Rotate: {0:d} degrees".format(angle1)) ax1.view_init(30,angle1) plot1.save()
Here is the output of the Python code.
