Add a toolbar to a chart.
This function adds a toolbar containing three tool-buttons (pan, rubber-band zoom, and center-point zoom) to a chart. Each tool uses mouse-drag for its specific functionality. Additionally, the mouse wheel can be used for zooming in and out, regardless of the selected tool.
The toolbar includes:
Pan: Drag to move the plot.
Rubber-band zoom: Drag to define a rectangular area to zoom into.
Center-point zoom: Drag up or down to zoom in or out from a center point.
Reset button: Click to reset the plot and tools to their original state.
Double-clicking anywhere on the plot resets it to its original coordinates, regardless of whether a tool is selected or not.
Limitations:
The toolbar does not work with interactive maps.
The toolbar cannot be used with plots using a polar coordinate system.

Parameters
Controls how zooming in affects the size of geometry objects on the plot. Currently, works only with the geomPoint layer and layers based on it (geomJitter, geomSina, etc.).
0– size never increases.-1– size will be increasing without limits.n– the number of times the size of objects will increase (relative to the initial state of the plot). Farther zooming will no longer affect the size.
default = "max" ("x", "y", "min", "max"). Defines the axis along which the scaling factor for geometry objects will be calculated.
"x"– size changes only when zooming in/out along the x-axis."y"– size changes only when zooming in/out along the y-axis."min"– size changes when zooming in/out along any axis, but the change is determined by the axis with the minimum zoom factor."max"– size changes when zooming in/out along any axis, but the change is determined by the axis with the maximum zoom factor.
