+ * @fileoverview Description of this file. + * @author danvk@google.com (Dan Vanderkam) * - * There's a huge variety of options that can be passed to this method. For a - * full list, see http://dygraphs.com/options.html. + * A ticker is a function with the following interface: * - * @param {Object} input_attrs The new properties and values - * @param {boolean} block_redraw Usually the chart is redrawn after every - * call to updateOptions(). If you know better, you can pass true to - * explicitly block the redraw. This can be useful for chaining - * updateOptions() calls, avoiding the occasional infinite loop and - * preventing redraws when it's not necessary (e.g. when updating a - * callback). + * function(a, b, pixels, options_view, dygraph, forced_values); + * -> [ { v: tick1_v, label: tick1_label[, label_v: label_v1] }, + * { v: tick2_v, label: tick2_label[, label_v: label_v2] }, + * ... + * ] + * + * The returned value is called a "tick list". + * + * Arguments + * --------- + * + * [a, b] is the range of the axis for which ticks are being generated. 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. */ -Dygraph.prototype.updateOptions = function(input_attrs, block_redraw) { - if (typeof(block_redraw) == 'undefined') block_redraw = false; - // mapLegacyOptions_ drops the "file" parameter as a convenience to us. - var file = input_attrs.file; - var attrs = Dygraph.mapLegacyOptions_(input_attrs); +/*jshint sub:true */ +/*global Dygraph:false */ +"use strict"; - // TODO(danvk): this is a mess.
