forked from KolibriOS/kolibrios
Graph (branch: tcc_current):
- Code refactoring - Optimization of code (for example, log2(n) searching) and memory usage - Some possible memory corruption fixed - Previous graph will be erased from window if error occured - Fixed bug with provided array of non-sorted points: so now you can pass points in any order - Fixed important bug with graphic rendering (big thanks to turbocat for asm rounding function) - Changed error messages; now you can see line/byte of file where syntax error is; added checking if provided frame of graph is invalid - Autochoosing of an optimal single step for both axises - Added support for reading any number of different functions. You will have to end previous function with ';' if you want to pass another one. They will be rendered on a graph in order you passed them. git-svn-id: svn://kolibrios.org@9778 a494cfbc-eb01-0410-851d-a64ba20cac60
