It is quite simple to create this pattern with Canvas or B4XCanvas. Create a Path with the points and fill it. Then draw the thick lines.

Sub Globals

    'These variables can only be accessed from this module.

    Private sv1 As SparkView
    Private sv2 As SparkView
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("Layout1")
 
    sv1.FillType = sv1.FT_NONE
    sv1.Data = Array As Float(15,16.5,16.70,17,15,15,15)
 
    sv2.FillType = sv2.FT_DOWN
    sv2.Data = Array As Float(0,17,36,52,85,115,135,140,100,130,130)

My problem is any of chart library doesn't support work with 20%x and 10%y sizes.

Click to expand...

Sub PercentX(value As Double) As Double
    Return value * 100%x
End Sub

Sub PercentY(value As Double) As Double
    Return value * 100%y
End Sub

'34%x = PercentX(0.34)
'98%y = PercentY(0.98)

    'Do not forget to load the layout file created with the visual designer. For example:

    sv1.FillType = sv1.FT_NONE

    sv2.FillType = sv2.FT_DOWN
    sv2.Data = Array As Float(0,17,36,52,85,115,135,140,100,130,130)


End Sub
