The axis range related settings allow you to modify the range displayed by the axis, or to adjust it in several modes. Following is a description of the axis range related settings:
Range
- Begin - allows you explicitly specify the axis begin value in numeric or date time format. If you do not provide one the control will automatically calculate the range begin value based on the Min expression and formula specified on the General tab page. This value is empty by default.
- End - allows you explicitly specify the axis end value in numeric or date time format. If you do not provide one the control will automatically calculate range end value based on the Max expression and formula specified on the General tab page. This value is empty by default.
Range Inflate
The range inflate mode allows you to additionally inflate the range of the axis (be it custom or automatically calculated) in order to improve the visual appearance of the chart on the screen. You can choose from the following options:
- Auto - in this mode the control will automatically inflate the range to the nearest major begin and end ticks so that the scale always starts and ends on an exact tick.
- Tick - in this mode the control will round the range to the nearest major begin and end ticks. You can also select whether only the begin or end value of the axis range should be rounded to the nearest tick by checking the "Inflate Range Begin" and "Inflate Range End" check boxes.
- Logical - in this mode you can provide a custom inflate in logical units (e.g. the units used for the pointers and ranges being displayed on the axis). This is done by specifying a value in the "Logical Inflate Begin" and "Logical Inflate End" settings.
- Absolute - in this mode you can provide a custom inflate in points. The axis will inflate the range so that the space between the automatically calculate min and max values and the actual begin and end of the axis is equal to the amount you specified using the "Absolute Inflate Begin" and "Absolute Inflate End" settings.
