wx.lib.plot.utils¶This is a collection of utilities used by the wx.lib.plot package.
Functions Summary¶s -> (s0,s1), (s1,s2), (s2, s3), … |
|
Raise PendingDeprecationWarning and display a message. |
|
Creates a scaled and shifted 2x1 numpy array of [x, y] values. |
|
Wrapper around |
Classes Summary¶Generic class for describing which sides of a box are displayed. |
|
Base class for warnings about deprecated features. |
|
Decorator / Context Manager to revert pen or brush changes. |
pairwise(iterable)¶s -> (s0,s1), (s1,s2), (s2, s3), …
pendingDeprecation(new_func)¶Raise PendingDeprecationWarning and display a message.
Uses inspect.stack() to determine the name of the item that this is called from.
new_func (string.) – The name of the function that should be used instead.
scale_and_shift_point(x, y, scale=1, shift=0)¶Creates a scaled and shifted 2x1 numpy array of [x, y] values.
The shift value must be in the scaled units.
x (float) – The x value of the unscaled, unshifted point
y (float) – The y valye of the unscaled, unshifted point
scale (np.array) – The scale factor to use [x_sacle, y_scale]
shift (np.array) – The offset to apply [x_shift, y_shift].
Must be in scaled units
a numpy array of 2 elements
np.array
Note
\(new = (scale * old) + shift\)
set_displayside(value)¶Wrapper around _DisplaySide that allows for “overloaded” calls.
If value is a boolean: all 4 sides are set to value
If value is a 2-tuple: the bottom and left sides are set to value
and the other sides are set to False.
If value is a 4-tuple, then each item is set individually: (bottom,
left, top, right)
value (bool, 2-tuple of bool, or 4-tuple of bool) – Which sides to display.
TypeError if setting an invalid value.
ValueError if the tuple has incorrect length.
