fortplot_contour_rendering

Contour plot rendering module

This module handles all contour plot rendering operations including contour level tracing, marching squares algorithm, and contour line drawing. Contour lines are smoothed using Catmull-Rom spline interpolation to reduce the polygonal appearance from marching squares.

Uses

Subroutines

public subroutine render_contour_plot(backend, plot_data, x_min_t, x_max_t, y_min_t, y_max_t, xscale, yscale, symlog_threshold, width, height, margin_left, margin_right, margin_bottom, margin_top)
