For a - * numeric axis, these will simply be numbers. For a date axis, these will be - * millis since epoch (convertable to Date objects using "new Date(a)" and "new - * Date(b)"). - * - * opts provides access to chart- and axis-specific options. It can be used to - * access number/date formatting code/options, check for a log scale, etc. - * - * pixels is the length of the axis in pixels. opts('pixelsPerLabel') is the - * minimum amount of space to be allotted to each label. For instance, if - * pixels=400 and opts('pixelsPerLabel')=40 then the ticker should return - * between zero and ten (400/40) ticks. - * - * dygraph is the Dygraph object for which an axis is being constructed. - * - * forced_values is used for secondary y-axes. The tick positions are typically - * set by the primary y-axis, so the secondary y-axis has no choice in where to - * put these. It simply has to generate labels for these data values. - * - * Tick lists - * ---------- - * Typically a tick will have both a grid/tick line and a label at one end of - * that line (at the bottom for an x-axis, at left or right for the y-axis). - * - * A tick may be missing one of these two components: - * - If "label_v" is specified instead of "v", then there will be no tick or - * gridline, just a label. - * - Similarly, if "label" is not specified, then there will be a gridline - * without a label. - * - * This flexibility is useful in a few situations: - * - For log scales, some of the tick lines may be too close to all have labels. - * - For date scales where years are being displayed, it is desirable to display - * tick marks at the beginnings of years but labels (e.g. "2006") in the - * middle of the years. - */ - -/*jshint globalstrict:true, sub:true */ -/*global Dygraph:false */ -"use strict";
