Module enthought.chaco2.data_range

Functions

calc_bounds(low_set, high_set, mins, maxes, epsilon, tight_bounds, track_amount)

Calculates bounds for a given 1-D set of data.

low_set : 'auto', 'track', or number: Current low setting
high_set : 'auto', 'track', or number: Current high setting
mins : list of numbers: Potential minima.
maxes : list: Potential maxima.
epsilon : number: Minimum percentage difference between bounds
tight_bounds : Boolean: Do 'auto' bounds imply an exact fit to the data? If False, they pad a little bit of margin on either side.
track_amount : number: The amount by which a 'track' bound tracks another bound.

(min, max) for the new bounds. If either of the calculated bounds is NaN, returns (0,0).

Setting both low_set and high_set to 'track' is an invalid state; the method copes by setting high_set to 'auto', and proceeding.
