Waveform Charts vs GraphsWaveform ChartOne datapoint at a timeShows history of received valuesThe chart is updated whenever a new datapoint is receivedOnly receives dataX-axis is timeWaveform GraphShows many datapoints at a timeShows data arraysThe graph is updated when alle datapoints are availableAll points plotted simultaneously 14Waveform GraphsReceives data in the form ofInitial X-valueDelta XY data Numerical arrayCan also just receive Y-dataInitial X-value is 0 by defaultDelta X is 1 by default15
