Christian Hergert	50ccd73592	visualizers: use double instead of float ... To give us less changes of incorrect values when converting between scales (at the cost of 2x the array size).	2018-06-16 20:22:53 -07:00
Christian Hergert	571c2320da	pointcache: add PointCache utility class ... This is a simple cache that keeps x,y pairs for use when drawing visualizers. To keep this generic, and save on memory, we simply store the x,y coordinates as floats between 0.0 and 1.0. This saves us roughly 50% on each data point over the 2 8-byte numbers we would otherwise store. Obviously, we could take this further and make some fancy index storage with run-length-encode values, but this should work for now and allow us to get more exotic later.	2016-09-26 17:34:58 -07:00
