Strip Chart Demo #540
Description
Describe the bug
It seems the plot.Clear() does not remove a previously plotted PlotSignal
To Reproduce
(1) Use plt.PlotSignal to plot a signal.
(2) on the same form, use plt.Clear() to clear all Plottables.
(3) add plot.Scatter
(4) render the form
(5) plot seems to switch between the Signal and Scatter plots.
The code below shows how the signal can be removed. However, I thought .Clear() should have done that.
.Clear(Of did not seem to remove the signal either.
With Me._ScottPlot.plt
.Clear()
Me._Signal = .PlotSignal(Me.OrdinateValues, Me.SamplingRate, markerSize:=0)
.Title("'Sampled' Sine Wave")
.YLabel("wave")
.XLabel("Seconds")
.Grid(Me._GridCheckBox.Checked)
.AxisAuto(0)
End With
With Me._ScottPlot.plt
.Clear()
If Me.Signal IsNot Nothing Then .Remove(Signal)
.PlotScatter(Me.AbscissaValues, Me.OrdinateValues)
.PlotScatter(Me.AbscissaValues, Me.OrdinateCosineValues)
.Title("Sine Wave Phase fixed size")
.YLabel("signals")
.XLabel("phase")
.AxisAuto(0)
End With
