1. A method for a handheld computer having a graphical display for showing multiple points of data in real-time from a microcontroller-driven analog measurement instrument via a low speed, wired or wireless transport, comprising:

  • performing a finite amount of measurements taken at predetermined intervals from a sensor by the measurement instrument wherein said finite amount of 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;

    storing said finite amount of measurements in a signal buffer of the handheld computer wherein mathematical transformations are executed on said finite amount of measurements within said signal buffer as instructed from software running on the handheld computer; and

    scaling either all or a contiguous subset of said transformed measurements into an array of integers that denote display coordinates in a predetermined viewing area on the graphical display of the handheld computer wherein said display coordinate integer array is then compressed before it is serially transported to the handheld computer for viewing.
