GraphPlot — Charts, Geometry

GraphPlot is a compact math toolkit for plotting functions, building charts and constructing geometric figures on Android — seven tools in one app, fully offline.

Tools:
• Graph by points — enter coordinates, plot a connected graph, adjust scale
• Function graph — plot y=f(x) and x=f(y) with sin, cos, ln, sqrt, π, etc.; find axis intersections; view a table of values
• Quick Plotter — instantly plot formulas; compare two functions side by side; explore popular graph examples; export PNG
• Geometry calculator — points, segments, lines, rays, parallels, perpendiculars, triangles, rectangles, polygons, circles; distances, angles, midpoints, bisectors, altitudes,
medians
• Bar chart — vertical or horizontal, custom colors, PNG export
• Line chart — smooth or straight, solid/dashed/dotted, PNG export
• Pie chart — pie, doughnut or polar area; color schemes; PNG/JPG/JSON export
