StraboTools vs GraphOE Graphing Calculator

StraboTools is designed to aid geologic field work by providing quantitative data that are otherwise difficult to estimate in the field. The app was developed for work in plutonic rocks such as granite, but it can be useful in field work in any type of rock and for study of thin sections as well. The app analyzes a photograph taken within the app or imported into it. •The Edge Fabric tool plots an ellipse that summarizes the orientations of image brightness gradients. In rocks with a fabric produced by deformation, this ellipse provides the orientation of the fabric and an axial ratio, which correlates with bulk deformation. The tool also reports the orientation in space of the line defined by the long axis of the ellipse. If, for example, the fabric being measured is planar, then these intersection lineations will lie on a great circle. Edge fabric diagrams are useful both in the field and for analysis of photomicrographs. •The Color Index tool allows quantitative determination of the color index (CI; area percent dark minerals) from a photograph. The user takes a photograph and then moves a slider to highlight those pixels darker than a certain threshold. The resulting area percent is displayed. Both adaptive and full-image thresholding are available. •Edge Detect applies an edge detection filter to the image. This can be useful in highlighting subtle features in an outcrop and in interpreting edge fabric ellipses.

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.
