YAxis Property

Use this property to return/set values that determines the grid and scale characteristics for a specific y-axis. YAxis is an array from 0 to (NumYScales - 1) and it uses the Line Class set of properties for its Grid characteristics and the YScale Class set of properties for its Scale characteristics.

Syntax

[Visual Basic]
Property YAxis(YAxisNumber As Integer) As C_YSCALEPROP

[C#]
C_YSCALEPROP XYChartNETCtl.get_YAxis(int YAxisNumber)

[C++]
property XYChartNet::XYChartNETCtl::C_YSCALEPROP ^ XYChartNet::XYChartNETCtl::YAxis[int]

Parameters

YAxisNumber: The index of the y-axis to set/get. Valid values are 0..(NumYScales - 1).

Remarks

For each y-axis scale label, up to 20 characters, across two rows, can be displayed on the chart. For example, "Speed" & Chr(13) & Chr(10) & "m/s", will display "Speed" in the label's first row and "m/s" in the label's second row. A carriage return - Chr(13) - and a linefeed - Chr(10) - are required to indicate the text spans two rows.
