The present invention provides a method for a handheld computer with a graphical display showing multiple points of data in real-time from a microcontroller-driven analog measurement instrument via a low speed, wired or wireless transport. A finite amount of measurements are taken at a predetermined interval from a sensor wherein the measurements are converted into a digital word using an Analog to Digital converter and a high speed microcontroller performing all the timing operations to read the sensor. The measurements read from the Analog to Digital converter are then stored in a signal buffer where mathematical transformations, such as integrations and domain conversions are done on the signal buffer as instructed from software running on a client machine. Once the desired transformations are complete either all or a contiguous subset of the measurements are scaled to an array of integers that denote display coordinates in a predetermined viewing area on the clients LCD display. This display coordinate integer array is then compressed before it is sent to the client for viewing via either a wired serial transport or a wireless serial transport.
