Module: wibox.widget.graph

A graph widget.

The graph goes from left to right. To change this to right to left, use a wibox.container.mirror widget. This can also be used to have data shown from top to bottom.

To add text on top of the graph, use a wibox.layout.stack and a wibox.container.align widgets.

To display the graph vertically, use a wibox.container.rotate widget.

Usage example

Usage:

    wibox.widget {
    max_value = 29,
    widget = wibox.widget.graph
}

group_colors table
Set the colors for data groups.

Colors in this table are used to paint respective data groups. When this property is unset (default), the color property is used instead for all data groups. When this property is set, but there's no color for a data group in it (i.e. group_colors[group] is nil or false), then the respective data group is disabled, i.e. not drawn.

Usage example

Type constraints:

  • colors table A table with colors for data groups.

See also:

Usage:

    local colors_normal = {
    "#ff0000",
    "#00ff00", -- the data group is green
    "#0000ff"
}
local colors_transparent = {
    "#ff0000",
    "#00000000", -- the data group is transparent
    "#0000ff"
}
local colors_disabled = {
    "#ff0000",
    nil, -- the data group is disabled
    "#0000ff"
}

wibox.widget {
    stack         = true,
    group_colors  = colors_normal,
    widget        = wibox.widget.graph,
}

wibox.widget {
    stack         = true,
    group_colors  = colors_transparent,
    widget        = wibox.widget.graph,
}

wibox.widget {
    stack         = true,
    group_colors  = colors_disabled,
    widget        = wibox.widget.graph,
}
max_value number · 1 signal
The maximum value the graph should handle.

This value corresponds to the top of the graph. If scale is also set, the graph never scales up below this value, but it automatically scales down to make all data fit. If scale and max_value are unset, max_value defaults to 1.

Usage example

Usage:

    wibox.widget {
    max_value = 30,
    widget    = wibox.widget.graph,
}

wibox.widget {
    max_value = 10,
    widget    = wibox.widget.graph,
}

Click to display more

Emit signals:

  • property::max_value When the max_value value changes.
    • self wibox.widget.graph The object which changed (useful when connecting many object to the same callback).
    • new_value max_value The new value affected to the property.
min_value number · 1 signal
The minimum value the graph should handle.

This value corresponds to the bottom of the graph. If scale is also set, the graph never scales up above this value, but it automatically scales down to make all data fit. If scale and min_value are unset, min_value defaults to 0.

Usage example

Usage:

    wibox.widget {
    max_value = 30,
    widget    = wibox.widget.graph,
}

wibox.widget {
    min_value = 10,
    max_value = 30,
    widget    = wibox.widget.graph,
}

Click to display more

Emit signals:

  • property::min_value When the min_value value changes.
    • self wibox.widget.graph The object which changed (useful when connecting many object to the same callback).
    • new_value min_value The new value affected to the property.
scale boolean · 1 signal
Set the graph to automatically scale its values. Default is false.

If this property is set to true, the graph calculates effective min_value and max_value based on the displayed data, so that all data fits on screen. The properties themselves aren't changed, but the graph is drawn as though min_value(max_value) were equal to the minimum(maximum) value among itself and the currently drawn values. If min_value(max_value) is unset, then only the drawn values are considered in this calculation.

Usage example

Usage:

    wibox.widget {
    scale  = false,
    widget = wibox.widget.graph,
}

wibox.widget {
    scale  = true,
    widget = wibox.widget.graph,
}

Click to display more

Emit signals:

  • property::scale When the scale value changes.
    • self wibox.widget.graph The object which changed (useful when connecting many object to the same callback).
    • new_value scale The new value affected to the property.
clamp_bars boolean · 1 signal
Clamp graph bars to keep them inside the widget for out-of-range values.

Drawing values outside the [min_value, max_value] range leads to bar shapes that exceed physical widget dimensions. Most of the time this doesn't matter, because bar shapes are rectangles and bar heights aren't large enough to trigger errors in the drawing system. However for some shapes and values it does make a difference and leads to visibly different and/or invalid result.

When this property is set to true (the default), the graph clamps bars' heights to keep them within the graph.

Usage example

Usage:

    wibox.widget {
    clamp_bars    = false,
    step_width    = 9,
    step_spacing  = 1,
    step_shape    = gears.shape.arrow,
    widget        = wibox.widget.graph,
}

wibox.widget {
    --clamp_bars    = true, --default
    step_width    = 9,
    step_spacing  = 1,
    step_shape    = gears.shape.arrow,

baseline_value number · 1 signal
The value corresponding to the starting point of graph bars. Default is 0.

Usage example

Usage:

    wibox.widget {
    --baseline_value = 0, --default
    min_value      = -5,
    max_value      = 5,

    • new_value step_shape The new value affected to the property.
stack boolean · 1 signal
Set the graph to draw stacks. Default is false.

When set to true, bars of each successive data group are drawn on top of bars of previous groups, instead of the baseline. This necessitates all data values to be non-negative. Negative values, if present, will trigger NaN indication.

Usage example

Usage:

    local colors = {
    "#ff0000",
    "#00ff00",
    "#0000ff"
}
local thin_arrow_shape = function(cr, width, height)

    • new_value stack The new value affected to the property.
nan_indication boolean · 1 signal
Display NaN indication. Default is true.

When the data contains NaN values, and nan_indication is set, the corresponding area, where the value bar should have been drawn, is filled with the nan_color from top to bottom. The painting is done after all other data is rendered, to make sure that it won't be overpainted and go unnoticed.

Usage example

Usage:

    local data = {
    -5, -4, 0/0, -2, -1, 0/0, 1, 2, 3, 0/0, 5,
}

wibox.widget {
    -- nan_indication = true, -- default
    -- default nan_color
    step_width    = 9,
    step_spacing  = 1,
    widget        = wibox.widget.graph,
}

wibox.widget {
    -- nan_indication = true, -- default

    • self wibox.widget.graph The object which changed (useful when connecting many object to the same callback).
    • new_value nan_color The new value affected to the property.
capacity integer or nil · 1 signal
Set the graph capacity.

Since the typical uses of the graph widget imply that add_value will be called an indefinite number of times, the widget needs a way to know, when to start discarding old values from the backing array.

When capacity is set, it defines the maximum number of values to keep in each data group.

When capacity is unset (default), the number is determined heuristically, which is sufficient most of the time, unless the widget gets resized too much too fast.

Type constraints:

  • capacity integer or nil The maximum number of values to keep per data group (nil for automatic guess). (default nil)

Type constraints:

  • colors table A table with colors for data groups.

See also:

Object methods

:pick_data_group_color (group_idx) -> gears.color
Determine the color to paint a data group with.

The graph uses this method to choose a color for a given data group. The default implementation uses a color from the group_colors table, if present, otherwise it falls back to color, then beautiful.graph_fg and finally to color red (#ff0000).

Parameters:

  • group_idx number The index of the data group.

Returns:

    gears.color The color to paint the data group's values with.
:compute_drawn_values_num (usable_width)
Determine how many values should be drawn for a given widget width.

The graph uses this method to determine the upper bound on the number of values that will be drawn from each data group. This affects, among other things, how many values will be considered for autoscaling, when scale is true, and, indirectly, how many values will be kept in the backing array, when capacity is unset.

The default implementation computes the minimum number that is enough to completely cover the given width with step_width + step_spacing intervals. The graph calls this method on every redraw and the width passed is the width of the value drawing area, i.e the graph borders are subtracted (2*border_width).

Parameters:

  • usable_width number
:add_value ([value=NaN[, group=1]])
Add a value to the graph.

The graph widget keeps its values grouped in data groups. Each data group is drawn with its own set of bars, starting with the latest value in the data group at the left edge of the graph.

Simply calling this method with a particular data group index is the only thing necessary and sufficient for creating a data group. Any natural integer as a group number is ok, but the user is advised to keep the group numbers low and consecutive for performance reasons.

There are no constraints on the value parameter, other than it should be a number.

Parameters:

  • value number The value to be added to a graph's data group. (default NaN)
  • group integer The index of the data group. (default 1)
:clear ()
Clear the graph.

Removes all values from all data groups.

:add_button (button) · Inherited from wibox.widget.base
Add a new awful.button to this widget.

Parameters:

  • button awful.button The button to add.
:emit_signal_recursive (signal_name, ...) · Inherited from wibox.widget.base

Emit a signal and ensure all parent widgets in the hierarchies also forward the signal.

This is useful to track signals when there is a dynamic set of containers and layouts wrapping the widget.

Note that this function has some flaws:

  1. The signal is only forwarded once the widget tree has been built. This happens after all currently scheduled functions have been executed. Therefore, it will not start to work right away.
  2. In case the widget is present multiple times in a single widget tree, this function will also forward the signal multiple times (once per upward tree path).
  3. If the widget is removed from the widget tree, the signal is still forwarded for some time, similar to the first case.

Parameters:

  • signal_name string
  • ... Other arguments
:index (widget[, recursive[, ...]]) -> (number, widget, table) · Inherited from wibox.widget.base
Get the index of a widget.

Parameters:

  • widget widget The widget to look for.
  • recursive boolean Recursively check accross the sub-widgets hierarchy. (optional)
  • ... widget Additional widgets to add at the end of the sub-widgets hierarchy "path". (optional)

Returns:

  1. number The widget index.
  2. widget The parent widget.
  3. table The hierarchy path between "self" and "widget".
:connect_signal (name, func) · Inherited from gears.object

Connect to a signal.

Usage example output:

In slot [obj]   foo bar 42

Parameters:

  • name string The name of the signal.

-- It is also possible to add as many random arguments are required.
o:emit_signal("my_signal", "foo", "bar", 42)
-- Finally, to allow the object to be garbage collected (the memory freed), it

-- This time, the slot wont be called as it is no longer connected.
o:emit_signal "my_signal"
:weak_connect_signal (name, func) · Inherited from gears.object
Connect to a signal weakly.

This allows the callback function to be garbage collected and automatically disconnects the signal when that happens. Warning: Only use this function if you really, really, really know what you are doing.

Parameters:

  • name string The name of the signal.
  • func function The callback to call when the signal is emitted.
:disconnect_signal (name, func) · Inherited from gears.object
Disonnect from a signal.

Parameters:

  • name string The name of the signal.
  • func function The callback that should be disconnected.
:emit_signal (name, ...) · Inherited from gears.object
Emit a signal.

Parameters:

  • name string The name of the signal
  • ... Extra arguments for the callback functions. Each connected function receives the object as first argument and then any extra arguments that are given to emit_signal()

Signals

widget::layout_changed · Inherited from wibox.widget.base
When the layout (size) change. This signal is emitted when the previous results of :layout() and :fit() are no longer valid. Unless this signal is emitted, :layout() and :fit() must return the same result when called with the same arguments.
