      See Also:

    • setCategories

      public abstract void setCategories(String... categories)

      If categories are present for the axis, names are used instead of numbers for that axis. Since Highcharts 3.0, categories can also be extracted by giving each point a name and setting axis type to category. However, if you have multiple series, best practice remains defining the categories array.

      Example: 

       categories: ['Apples', 'Bananas', 'Oranges']

      Index of another axis that this axis is linked to. When an axis is linked to a master axis, it will take the same extremes as the master, but as assigned by min or max or by setExtremes. It can be used to show additional info, or to ease reading the chart by duplicating the scales.

    • getMaxPadding

      public abstract Number getMaxPadding()
      See Also:

    • setMaxPadding

      public abstract void setMaxPadding(Number maxPadding)
      Padding of the max value relative to the length of the axis. A padding of 0.05 will make a 100px axis 5px longer. This is useful when you don't want the highest data value to appear on the edge of the plot area. When the axis' max option is set or a max extreme is set using axis.setExtremes(), the maxPadding will be ignored.

    • getMinPadding

      public abstract Number getMinPadding()
      See Also:

    • setMinPadding

      public abstract void setMinPadding(Number minPadding)
      Padding of the min value relative to the length of the axis. A padding of 0.05 will make a 100px axis 5px longer. This is useful when you don't want the lowest data value to appear on the edge of the plot area. When the axis' min option is set or a min extreme is set using axis.setExtremes(), the minPadding will be ignored.

    • getMinRange

      public abstract Number getMinRange()
      See Also:

    • setMinRange

      public abstract void setMinRange(Number minRange)

      The minimum range to display on this axis. The entire axis will not be allowed to span over a smaller interval than this. For example, for a datetime axis the main unit is milliseconds. If minRange is set to 3600000, you can't zoom in more than to one hour.

      The default minRange for the x axis is five times the smallest interval between any of the data points.

      On a logarithmic axis, the unit for the minimum range is the power. So a minRange of 1 means that the axis can be zoomed to 10-100, 100-1000, 1000-10000 etc.

      Note that the minPadding, maxPadding, startOnTick and endOnTick settings also affect how the extremes of the axis are computed.

    • getMinTickInterval

      public abstract Number getMinTickInterval()
      See Also:

    • setMinTickInterval

      public abstract void setMinTickInterval(Number minTickInterval)
      The minimum tick interval allowed in axis values. For example on zooming in on an axis with daily data, this can be used to prevent the axis from showing hours.

    • getMinorTickInterval

      public abstract String getMinorTickInterval()
      See Also:

    • setMinorTickInterval

      public abstract void setMinorTickInterval(String minorTickInterval)

      Tick interval in scale units for the minor ticks. On a linear axis, if "auto", the minor tick interval is calculated as a fifth of the tickInterval. If null, minor ticks are not shown.

      On logarithmic axes, the unit is the power of the value. For example, setting the minorTickInterval to 1 puts one tick on each of 0.1, 1, 10, 100 etc. Setting the minorTickInterval to 0.1 produces 9 ticks between 1 and 10, 10 and 100 etc. A minorTickInterval of "auto" on a log axis results in a best guess, attempting to enter approximately 5 minor ticks between each major tick.

      If user settings dictate minor ticks to become too dense, they don't make sense, and will be ignored to prevent performance problems.

      On axes using categories, minor ticks are not supported.

    • getMinorTickLength

      public abstract Number getMinorTickLength()
      See Also:

    • setMinorTickLength

      See Also:

      public abstract void setOffset(Number offset)

      See Also:

    • setTickInterval

      public abstract void setTickInterval(Number tickInterval)

      The interval of the tick marks in axis units. When null, the tick interval is computed to approximately follow the tickPixelInterval on linear and datetime axes. On categorized axes, a null tickInterval will default to 1, one category. Note that datetime axes are based on milliseconds, so for example an interval of one day is expressed as 24 * 3600 * 1000.

      On logarithmic axes, the tickInterval is based on powers, so a tickInterval of 1 means one tick on each of 0.1, 1, 10, 100 etc. A tickInterval of 2 means a tick of 0.1, 10, 1000 etc. A tickInterval of 0.2 puts a tick on 0.1, 0.2, 0.4, 0.6, 0.8, 1, 2, 4, 6, 8, 10, 20, 40 etc.

      If the tickInterval is too dense for labels to be drawn, Highcharts may remove ticks.

    • setUniqueNames

      public abstract void setUniqueNames(Boolean uniqueNames)
