Generate nicely looking random data

Thingworx Signal generator

Why use it?

In many apps you have to generate data that does not look completely random. This project helps you generate that data.

How to use it?

• If you want to generate a chart, then use the getNoise service SignalGenerator thing. This service returns a infotable with your data. This are the required parameters:
  • scale: how "contiguous" you want the signal to be
  • amplitude: how big is the dynamic part of the signal
  • additiveGradient: Gain, or by how much you want each point to grow
  • offset: offset the signal from 0 (smallest data point)
  • intervalStart and intervalEnd: the generated signal will sit between this two dates
  • sampleTime: in ms, how often should the signal change
• If you want to update a property value based, using a timer, you can create a thing that inherits SignalGeneratorTemplate, and call getNextValue. The same parameters as above apply.

How it works

It uses a Perlin Noise 1D generator.
