Bokeh comes with a number of interactive tools that can be used to report information, to change plot parameters such as zoom level or range extents, or to add, edit, or delete glyphs. Tools can be grouped into four basic categories:. These are tools that respond to single gestures, such as a pan movement. The types of gesture tools are:. For each type of gesture, one tool can be active at any given time, and the active tool is indicated on the toolbar by a highlight next to to the tool icon.

These are immediate or modal operations that are only activated when their button in the toolbar is pressed, such as the ResetTool. These are passive tools that report information or annotate plots in some way, such as the HoverTool or CrosshairTool.

These are sophisticated multi-gesture tools that can add, delete, or modify glyphs on a plot. Since they may respond to several gestures at once, an edit tool will potentially deactivate multiple single-gesture tools at once when it is activated. In addition to information about all the individual tools, this chapter describes how the toolbar may be configured.

By default, Bokeh plots come with a toolbar above the plot. In this section you will learn how to specify a different location for the toolbar, or to remove it entirely. Valid values are:. If you would like to hide the toolbar entirely, pass None. Below is some code that positions the toolbar below the plot. At the lowest bokeh. This explicit way of adding tools works with any Bokeh Plot or Plot subclass, such as Figure. Tools can be specified by passing the tools parameter to the figure function.

The tools parameter accepts a list of tool objects, for instance:. Tools can also be supplied conveniently with a comma-separate string containing tool shortcut names:. This can also be done in conjunction with the tools keyword described above:.

Bokeh toolbars can have at most one active tool from each kind of gesture drag, scroll, tap. By default, Bokeh will use a default pre-defined order of preference to choose one of each kind from the set of configured tools, to be active. However it is possible to exert control over which tool is active.For each type of gesture, one tool can be active at any given time, and the active tool is indicated on the toolbar by a highlight next to to the tool icon.

Actions are immediate or modal operations that are only activated when their button in the toolbar is pressed. Inspectors are passive tools that report information or annotate the plot in some way. By default, Bokeh plots come with a toolbar above the plot.

However, this method does not allow setting properties of the tools. These tools are employed by panning on touch devices or left-dragging on mouse devices. The box selection tool allows the user to define a rectangular selection region by left-dragging a mouse, or dragging a finger across the plot area. The box select tool may be configured to select across only one dimension by setting the dimensions property to a list containing width or height. To clear the selection, press the ESC key.

The box zoom tool allows the user to define a rectangular region to zoom the plot bounds too, by left-dragging a mouse, or dragging a finger across the plot area. The lasso selection tool allows the user to define an arbitrary region for selection by left-dragging a mouse, or dragging a finger across the plot area.

The pan tool allows the user to pan the plot by left-dragging a mouse or dragging a finger across the plot region.

It is also possible to constrain the pan tool to only act on either just the x-axis or just the y-axis by setting the dimensions property to a list containing width or height. Additionally, there are tool aliases 'xpan' and 'ypan'respectively. These tools are employed by tapping on touch devices or left-clicking on mouse devices.

The polygon selection tool allows the user to define an arbitrary polygonal region for selection by left-clicking a mouse, or tapping a finger at different locations. Complete the selection by making a double left-click or tapping. The tap selection tool allows the user to select at single points by clicking a left mouse button, or tapping with a finger. These tools are employed by pinching on touch devices or scrolling on mouse devices. It is also possible to constraint the wheel zoom tool to only act on either just the x-axis or just the y-axis by setting the dimensions property to a list containing width or height.

Actions are operations that are activated only when their button in the toolbar is tapped or clicked. They are typically modal or immediate-acting. Inpectors are passive tools that annotate or otherwise report information about the plot, based on the current cursor position.

Any number of inspectors may be active at any given time. The inspectors menu in the toolbar allows users to toggle the active state of any inspector.

Th crosshair tool draws a crosshair annotation over the plot, centered on the current mouse position. The crosshair tool may be configured to draw accross only one dimension by setting the dimensions property to a list containing width or height. The hover tool pops up a tooltip div whenever the cursor is over a glyph. The information comes from the glyphs data source and is configurable through a simple tooltips dictionary that maps displayed names to columns in the data source, or to special known variables.

The hover tool is a passive inspector tool. The hover tool displays informational tooltips whenever the cursor is directly over a glyph.For each type of gesture, one tool can be active at any given time, and the active tool is indicated on the toolbar by a highlight next to to the tool icon. Actions are immediate or modal operations that are only activated when their button in the toolbar is pressed.

I have a simple graph of X-Y data points. I want my Bokeh figure to show me the integer value of each datapoint when I hover over it. I am close to getting what I want but when I hover over the data point, it shows a float and then higher up, it uses scientific notation. Is there a way to have the hover tool only return the integer values of X and Y and not use scientific notation? Adding my two cents. I figured out by you can control the decimal points by using the following code:.

Will, curious if you know how to scale y and then format it. This is great. Do you know if there is notation for formatting dates like this? I didn't manage to find this in the documents; do you happen to have a link where this is located? Chris sorry not aware of a flag for percentage formatting.

I suppose you already tried Python's formatting flags? What I'd do is to create another column in your data source and plot that instead, not perfect but might get you there. Unfortunately it's not in the docs as far as I know. I haven't chased down in the source code yet to find out how it's parsed but it's a bit different to the traditional python format strings.

The active tool is indicated on the toolbar by a highlight next to the tool. Actions are immediate or modal operations that are only activated when their button in the toolbar is pressed. Inspectors are passive tools that merely report information or annotate the plot in some way, and may always be active regardless of what other tools are currently active.

Bases: bokeh. This is an abstract base class used to help organize the hierarchy of Bokeh model types. It is not useful to instantiate on its own. A mapping of event names to lists of CustomJS callbacks. Typically, rather then modifying this property directly, callbacks should be added using the Model.

A mapping of attribute names to lists of CustomJS callbacks, to be set up on BokehJS side when the document is created.

No uniqueness guarantees or other conditions are enforced on any names that are provided, nor is the name used directly by Bokeh for any reason. List of events that are subscribed to by Python callbacks. This is the set of events that will be communicated from BokehJS back to Python for this model. Or simply a convenient way to attach any necessary metadata to a model that can be accessed by CustomJS callbacks, etc. No uniqueness guarantees or other conditions are enforced on any tags that are provided, nor are the tags used directly by Bokeh for any reason.

Apply a set of theme values which will be used rather than defaults, but will not override application-set values.

The passed-in dictionary may be kept around as-is and shared with other instances to save memory so neither the caller nor the HasProps instance should modify it. Collect the names of all DataSpec properties on this class. This method always traverses the class hierarchy and includes properties defined on any parent classes.

Collect a dict mapping the names of all DataSpec properties on this class to the associated properties. This is a convenience method that simplifies adding a CustomJS callback to update one Bokeh model property whenever another changes value. ValueError —. As a convenience, if the event name passed to this method is also the name of a property on the model, then it will be prefixed with "change:" automatically:. However, there are other kinds of events that can be useful to respond to, in addition to property change events.

For example to run a callback whenever data is streamed to a ColumnDataSourceuse the "stream" event on the source:. Find the PropertyDescriptor for a Bokeh property on a class, given the property name. Add a callback on this object to trigger when attr changes. This method optionally traverses the class hierarchy and includes properties defined on any parent classes. Query the properties values of HasProps instances with a predicate. Returns all Models that this object has references to.

Query this object and all of its references for objects that match the given selector. Raises an error if more than one object is found. Returns single matching object, or None if nothing is found :param selector: :type selector: JSON-like. In the context of a Bokeh server application, incoming updates to properties will be annotated with the session that is doing the updating. This value is propagated through any subsequent change notifications that the update triggers.

The session can compare the event setter to itself, and suppress any updates that originate from itself.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I am new to Bokeh and I am trying to apply hover tool tips over the plot. The x-axis of the plot has Timestamp values which are converted into epoch string. I've reviewed some same problems here and tried to use the workaround for my case but it doesn't seem to work.

On the plot it gives??? Since this answer was originally posted, new work has gone into Bokeh to make things simpler. A datetime field can be formatted as a datetime directly by the hover tool, by specifying a formatter, e.

It is no longer necessary to pre-format date fields in the data source as below. For more information see Formatting Tooltip Fields. The problem with your tooltip is you created a source with the string representation of the dates, but the p. So you have to pass in a columndatasource that has the tooltip, the x and y values.

Also note there is an open issue about the lack of formatting options in the bokeh tooltip. There might be an easier way to not have to format the datestrings as a separate column:. PS it would be better next time if you posted a working script with import statements, and a mocked up dataframe to make it possible to test.
