There are three chart axes. The x and y axes are always displayed and an optional 2nd y axis can be displayed by setting the Use Second Y-Axis parameter to true for at least one visible series.
The axes minimum, maximum, step and crossing locations are automatically computed based of the visible series data. To define the quantities manually, select the Custom Limits button in the Chart X-Axis and Chart Y-Axis groups; use the Min, Max, and Step text fields to enter the values.
The 2nd y axis parameters are found in the chart properties (see “Parameters”). To access the x or y axis properties in more detail, choose the arrow in the lower right corner of the Chart X-Axis or Chart Y-Axis group.
Limits (Range)/Minimum - Controls the lowest value on the axis. Only visible when Mode is set to Custom. (IAxisConfig/LimitMinimum)
Limits (Range)/Maximum - Controls the highest value on the axis. Only visible when Mode is set to Custom. (IAxisConfig/LimitMaximum)
Limits (Range)/Step - Controls the interval size between values on the axis. Only visible when Mode is set to Custom. (IAxisConfig/LimitStep)
Labels/Number Font Size - [PIXELS] - Controls the size of the axis number labels. (IAxisConfig/NumberFontSize)
Labels/Title Mode - Choose Custom for a user defined title, choose Automatic for a system generated title. (IAxisConfig/TitleMode)
Labels/Custom Title - Controls the axis title. Only visible if Title Mode is set to Custom. (IAxisConfig/CustomTitle)
Labels/Title Font Size - [PIXELS] - Controls the size of the axis title label. (IAxisConfig/TitleContSize)
Labels/Color - Controls the font color the axis labels and title. (IAxisConfig/LabelColor)
Scale/Type - Choose Linear to display the axis on a linear scale. Choose Logarithmic to display the axis on a logarithmic scale. (IAxisConfig/ScaleType)
Second Y-Axis/Scale/Log Base - Controls the base of the logarithmic format for the axis. Only visible if Type is set to Logarithmic. (IAxisConfig/ScaleLogBase)
Grid Lines/Style - Controls the style of the grid lines. (IAxisConfig/GridStyle)
Grid Lines/Thickness - [PIXELS] - Controls the size of the grid lines. (IAxisConfig/GridThickness)
Grid Lines/Color - Controls the color of the grid lines. (IAxisConfig/GridColor)
Crossing/Mode - Choose Custom for the user defined location where the axis intersects with its perpendicular axis. Choose Automatic for the axis to intersect with the perpendicular axis at the minimum value. (IAxisConfig/CrossingMode)
Crossing/Location - Controls the location the axis crosses with the perpendicular axis. Only visible if Mode is set to Custom. (IAxisConfig/CrossingLocation)
