Sets "fixed interval" mode.
Call this function to enable "fixed interval" mode. In this mode major intervals have the specified by nWidth size in pixels. An axis tries to display nValuesPerInterval values within this interval.
Zoom and Magnify increase or decrease the number of values per interval.
This mode is useful for historical charts, where X axis has no mean or formatted as date.
nWidth | Specifies fixed interval width in pixels. |
nValuesPerInterval | Specifies number of values per interval. It's recommended to set this parameter in range [1, nWidth]. |
