/** * @class Ext.d3.axis.Axis * @extend Ext.Base * * The d3.svg.axis component is used to display reference lines for D3 scales. * A thin wrapper around the d3.axis* and d3.scale* with an added ability to display * an axis title in the user specified position. This allows to configure axes declaratively * in any Ext component that uses them, instead of using D3's method chaining, which * would look quite alien in Ext views, as well as pose some technical and interoperability * issues (e.g. dependency management issues when views declared with Ext.define reference * `d3` directly). * * Note that this is a thin wrapper around the native D3 axis and scale, so when * any changes are applied directly to those D3 entities, for example * `ExtD3Axis.getScale().domain([30, 40])`, this class won't be nofied about such changes. * So it's up to the developer to account for them, like rerendering the axis `ExtD3Axis.render()` * or making sure that "nice" segmentation is preserved by chaining a call to `nice` after the * domain is set, e.g. `ExtD3Axis.getScale().domain([30, 40]).nice()`. * * The axis is designed to work with the {@link Ext.d3.svg.Svg} component. */ /** * @cfg {Object} axis * A config object to create a `d3.axis*` instance from. * A property name should represent an actual `d3.axis*` method, * while its value should represent method's parameter(s).

So a value such as `d3.timeDay` should be made a string * `'d3.timeDay'` that does not have any dependencies and will be evaluated at a later time, * when `d3` is already loaded. * For example, this * * d3.axisBottom().tickFormat(d3.timeFormat('%b %d')); * * is equivalent to this: * * { * orient: 'bottom', * tickFormat: "d3.timeFormat('%b %d')" * } * * Please see the D3's [SVG Axes](https://github.com/d3/d3-3.x-api-reference/blob/master/SVG-Axes.md) * documentation for more details. * @accessor */ /** * @cfg {Object} scale * A config object to create a `d3.scale*` instance from. * A property name should represent an actual `d3.scale*` method, * while its value should repsent method's parameter(s).
