Bases: ggrust.errors.GgrustError, builtins.IndexError

Raised when a layer or grid cell index is out of range or malformed.

Parameters:

• message (str) –

  The full message: the index, what it indexes and the valid range.

• index (object) –

  The index that was asked for.

• length (int) –

  How many layers (or grid cells) there are.

Examples:

>>> from ggrust import *
>>> from ggrust.errors import PlotIndexError
>>> data = {"weight": [2.6, 2.9, 3.2, 3.4, 3.6, 4.1], "mpg": [31, 28, 24, 22, 19, 15]}
>>> chart = ggplot(data, aes("weight", "mpg")) + geom_point()
>>> try:
...     frame = chart.layer_data(3)
... except PlotIndexError as error:
...     print(error.length)
