ZX mathematical function grapher

ZX mathematical function grapher is an excellent independent kernel mathematical function graphing software. It has the following functions: freely type expressions, supports all elementary functions of the two-dimensional rectangular coordinate system and polar coordinate system, all conic sections and arbitrary polygons, etc., and some advanced functions (Β, Γ, Lambert W, error, Riemann ζ, Bessel, etc.), and comes with a large number of system function templates (probabilistic and statistical functions) and custom functions. Supports parametric equation images. Can automatically find limits and calculus. Adjust the function's value range, related values, color, thickness, temporary hiding, whether the coordinate axis and grid are displayed, color, thickness, scale size, background color, whether to label expressions, etc. at any time. You can modify the axes and their letters, units, and letters of custom constants. You can optionally lock the aspect ratio, quickly zoom in and out on the coordinate axes, and drag the mouse to zoom. File access, export and print images.
