| axis {rbokeh} | R Documentation |
Customize x or y axis of a Bokeh figure.

fig |
Figure to modify. |
label |
A character string indicating the axis label. |
position |
The position of the axis. Either "below" or "above" for an x axis and "left" or "right" for a y axis. Note that multiple x and y axes can be coexist in a figure. |
log |
A logical indicating whether the axis should be on the log scale. |
draw |
A logical indicating whether the axis be drawn. This is useful when you want to disable an axis. |
ticker |
A ticker specificition (see "See Also" below). |
tickformatter |
A tickformatter specificition (see "See Also" below). |
axis |
An axis specificition (see "See Also" below). |
grid |
A grid specificition (see "See Also" below). |
