你可以通过如下方式来获取或者设置一个chart的坐标轴，坐标轴共有四种：主要（分类）坐标轴、主要（值）坐标轴、次要（分类）坐标轴、次要（值）坐标轴。
主要（分类）坐标轴、主要（值）坐标轴、次要（分类）坐标轴、次要（值）坐标轴的类型是一样的，你可以获取或设置它们的样式 (坐标轴可设置的属性包括:lineStyle, tickPosition, tickLabelPosition, format, title and gridLine)
主要网格线、次要网格线有着同样的类型，你可以获取或设置它们的样式 (网格线可设置的属性包括:color, width, visibility)
Logarithmic Axes: 图表的数据轴可以设置为对数轴.
Label Position: SpreadJS支持通过设置以下枚举值来设置轴的标签位置 GC.Spread.Sheets.Charts.TickLabelPosition.
high
low
nextToAxis
none
Axis Orientation: SpreadJS支持设置轴的方向
Display Unit: 通过 displayUnit 属性，你可以将百万/万亿显示为单位，而不是实际的大数字。 此功能有助于节省空间并更易于阅读。
Date axis: SpreadJS 图表支持日期轴，你可以的调整显示的日期单位，以及单位的跨度。
baseUnit
majorUnit
majorUnitScale
minorUnit
minorUnitScale
Crosses: SpreadJS支持通过设置数字或者以下枚举值来改变轴之间的交叉。GC.Spread.Sheets.Charts.AxisCrossPoint.
automatic
maximum
