probably they added it later on, posting here for future reference (see https://developers.google.com/chart/interactive/docs/gallery/linechart)
hAxis.viewWindowMode Specifies how to scale the horizontal axis to render the values within the chart area. The following string values are supported: - 'pretty' - Scale the horizontal values so that the maximum and minimum data values are rendered a bit inside the left and right of the chart area. This will cause haxis.viewWindow.min and haxis.viewWindow.max to be ignored. - 'maximized' - Scale the horizontal values so that the maximum and minimum data values touch the left and right of the chart area. This will cause haxis.viewWindow.min and haxis.viewWindow.max to be ignored. - 'explicit' - A deprecated option for specifying the left and right scale values of the chart area. (Deprecated because it's redundant with haxis.viewWindow.min and haxis.viewWindow.max.) Data values outside these values will be cropped. You must specify an hAxis.viewWindow object describing the maximum and minimum values to show. This option is only supported for a continuous <https://developers.google.com/chart/interactive/docs/customizing_axes#Terminology> axis. *Type:* string *Default:* Equivalent to 'pretty', but haxis.viewWindow.min and haxis.viewWindow.max take precedence if used. -- You received this message because you are subscribed to the Google Groups "Google Chart API" group.
