When I use a SplineLayer with the following code, it creates "folded" areas in the spline
line that are darker than the rest of the line. Anyway to avoid this? See image below the
code.
Thanks!
' The data for the line chart
Dim data() As Double = {85, 77, 50, 40, 75, 30, 20, 45, 45, 55, 85, 50, 55,
20, 30, 80, 25, 85, 30, 45, 80}
Dim data2() As Double = {62, 51, 56, 54, 58, 44, 24, 56, 54, 56, 62, 45, 86,
24, 44, 51, 65, 62, 44, 56, 51}
Dim data3() As Double = {51 ,60, 41, 62, 68, 40, 24, 41, 62, 41, 51, 43, 100,
24, 40, 60, 56, 51, 40, 41, 60}
' The labels for the line chart
Dim labels() As String = {"0", "1", "2", "3", "4", "5", "6", "7", "8", "9", _
"10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21"}
' Create a XYChart object of size 250 x 250 pixels
Dim c As XYChart = New XYChart(800, 250)
' Set the plotarea at (30, 20) and of size 200 x 200 pixels
c.setPlotArea(30, 20, 775, 200)
Dim slayer As SplineLayer = c.addSplineLayer()
' Set the default line width to 2 pixels
' Add the three data sets to the line layer. For demo purpose, we use a dash line
' color for the last line
slayer.addDataSet(data, &H800E0E0E)
Dim ds as DataSet = slayer.getDataSet(0)
ds.setLineWidth(20)
Dim layer As LineLayer = c.addLineLayer2()
layer.setLineWidth(2)
layer.addDataSet(data2, c.dashLineColor(&H3333ff, Chart.DashLine))
layer.addDataSet(data3, &H663300)
' Set the labels on the x axis.
c.xAxis().setLabels(labels)

SplineLayer with semi-transparent line has darker overlapped areas...
