Issue Details
When setting a Waveform Chart scale to a small value (~0.001) and writing multiple plots with low sample rates, a duplicate waveform that is slightly out of phase can appear. The behavior is shown below in the following image (with the x-scale being set to a range of 0.01). The Waveform Chart with the small scale (on the left), has a duplicate triangle wave that is out of phase, whereas when the scale is changed to a larger range (chart on the right), the duplicate waveform disappears.
