Graph Sketcher 1.5

Graph Sketcher lets you make elegant and precise graphs in seconds, simply by sketching what you want. The interface is intuitive and simple so that you can quickly find what you want while underground algorithms take care of all the messy details. It's no problem if your data is already in a spreadsheet or database program -- just copy and paste it right into Graph Sketcher. All adjustments you make are displayed in real time, so fine-tuning is a piece of cake. Best of all, the program has gone through rigorous user interface testing -- the only way to really find out how to make software intuitive to use.
Graph Sketcher is a great solution for students and teachers in the sciences and social sciences who want to make plots and graphs for problem sets, lab reports, and presentations. The ability to simply sketch lines and labels representing supply and demand curves makes Graph Sketcher by far the best solution available for introductory economics. And its data plotting and best-fit line capabilities are great for physics and chemistry. It even lets you easily draw the kind of "graphs" that mathematicians use in graph theory: those with vertices connected by edges.
Graph Sketcher is also ideal for 2-D graphing tasks that require more flexibility than traditional programs allow. For example, it's easy to add as many lines as you like to represent goals, cutoffs, or other boundaries. It's also easy to add labels anywhere on the graph surface. And you can enter data visually with a click of the mouse, rather than manually typing in x- and y-values, which makes it great as a health tracker or a way to incrementally record any type of progress.
What's new in this version:
Bar charts (a new type of "point shape") Ability to swap the axes Ability to copy the graph as an image (to paste into other applications) Paste & Replace command for using new data with an existing graph layout Quick Look integration for Mac OS 10.5 Many smaller fixes and enhancements
