3D Plotting

Source: 3d_plotting.f90

3D plotting (lines and surfaces) with axes, ticks, and labels.

  • 3D line plots: helices and parametric curves
  • 3D scatter plots: multiple patterns and marker types
  • 3D surface plots: mathematical functions and meshes
  • Mixed plots: combining 2D and 3D in one figure
  • Plot combinations: multiple 3D plot types together
call fig%add_3d_plot(x, y, z, label="3D Line")

call fig%add_scatter_3d(x, y, z, label="Scatter", marker='o')

call fig%add_surface(x_grid, y_grid, z_grid, label="Surface")
  • Automatic 3D Detection: fortplot automatically detects 3D data
  • No Special Initialization: Same fig%initialize() for 2D and 3D
  • Mixed Dimensionality: Can combine 2D and 3D plots in same figure
  • Surface Grid Requirements: size(z_grid,1) == size(x_grid) and size(z_grid,2) == size(y_grid)
  • Memory Management: Uses allocatable arrays for efficient memory usage
