When a Bokeh plot is rendered, normally a tool bar appears on the right side of the figure. It contains a default set of tools. First of all, the position of toolbar can be configured by toolbar_location property in figure() function. This property can take one of the following values −

• “above”
• “below”
• “left”
• “right”
• “None”

For example, following statement will cause toolbar to be displayed below the plot −

Fig = figure(toolbar_location = "below")

This toolbar can be configured according to the requirement by adding required from various tools defined in bokeh.models module. For example −

Fig.add_tools(WheelZoomTool())

The tools can be classified under following categories −

• Pan/Drag Tools
• Click/Tap Tools
• Scroll/Pinch Tools
