Systems and methods for displaying digitized waveform data on a pixilated screen are provided. Certain methods include retrieving waveform data that exists as a plurality of sequential samples in a buffer. A first sample is associated with a first point of a pixilated screen. A second sample that follows the first sample is associated with a second point of the screen. A boundary of a rectangular line segment connecting the points is determined. For each pixel of the pixilated screen that has any portion inside the boundary of the rectangular line segment, a number of subpixels within the pixel that have any portion inside the boundary of the rectangular line segment is determined and that number of subpixels is correlated with an intensity value that is then associated with the pixel. Waveform data is displayed by painting pixels of the screen with the associated intensity values. |
