A Strip Chart - How to Create Application
Before computers exist or were taking their first steps, a Strip chart was a way to visualize an analog electrical signal.
Voltage was moved by a needle or pen, and the trace was plotted on scrolling graph paper. The device was called a Strip chart recorder.
The typical applications were for example:
- Seismography, earthquakes, and movement of tectonic plates activity monitoring
- Polygraphy tests, physiological measurements such as lie detector
- Electroencephalography (EEG), brain electric activity monitoring
- Any electrical signal change plotting, typically over time
An analog Electroardiogram (ECG) strip chart.
Nowadays, electrical signals are converted into digital format by using a data acquisition device, including an analog-to-digital (A/D) converter, which can be processed and stored by computers or portable data devices.
Strip chart applications are not typically plotted on paper anymore but are shown as waveform charts.
You can find how to build such application (with LightningChart) and more information about Strip chart in following blog.
