Welcome to GraphOE, It is a tool for graphing/plotting functions in 2D! We currently support the following features: 1. Explicit, Implicit, Parametric, and Polar graphs. 2. Region labeling of inequalities for explicit and implicit functions. 3. Adjustable variables and animations. 4. Auto intersections for explicit and implicit curves. 5. Point of interest like minima, maxima and inflection points, for explicit curves. 6. Cartesian(Rectangular) and Polar(Circular) coordinate system. 7. Intuitive zoom-in/zoom-out and panning. 8. Screenshots with various backgrounds for canvas. 9. Auto saving feature. Saves to the local storage. 10. Functions: sin, cos, tan, cosec, sec, cot, sinh, cosh, tanh, asin, acos, atan, asinh, acosh, atanh, log and exp 11. Intuitive equation editor with beautiful fonts. 12. Unlimited number of functions in single canvas. 13. Fully supported dark mode or any color background mode. 14. Scatter plots with point list Tips and Tricks 1. Touch near the intersection or point of interest to label them. 2. Change the background of the canvas to black to enable dark mode. 3. To create a scatter plot just add all the points like (1,2),(2,3), etc to the equation editor We hope that GraphOE will be useful for you in understanding the graphs of various functions.
