         * **custom series**
         *
         * `custom series` supports customizing graphic elements, and then generate
         * more types of charts.
         *
         * echarts manages the creation, deletion, animation and interaction
         * with other components (like
         * [dataZoom](https://echarts.apache.org/en/option.html#dataZoom)
         * 、
         * [visualMap](https://echarts.apache.org/en/option.html#visualMap)
         * ), which frees developers from handle those issue themselves.
         *
         * **For example, a "x-range" chart is made by custom sereis:**
         *
         * [see doc](https://echarts.apache.org/en/option.html#series-custom)
         *
         * **
         * [More samples of custom series](https://echarts.apache.org/examples/en/index.html#chart-type-custom)

         * **
         *
         * **Customize the render logic (in renderItem method)**
         *
         * `custom series` requires developers to write a render logic by themselves.
         * This render logic is called
         * [renderItem](https://echarts.apache.org/en/option.html#series-custom.renderItem)
         * .
         *
         * For example:
         *
         * [see doc](https://echarts.apache.org/en/option.html#series-custom)
         *
         * [renderItem](https://echarts.apache.org/en/option.html#series-custom.renderItem)
         * will be called on each data item.
         *
         * [renderItem](https://echarts.apache.org/en/option.html#series-custom.renderItem)
         * provides two parameters:
         *
         * + [params](https://echarts.apache.org/en/option.html#series-custom.renderItem.arguments.params)
         * : provides info about the current series and data and coordinate
         * system.
         * + [api](https://echarts.apache.org/en/option.html#series-custom.renderItem.arguments.api)
         * : includes some methods.
         *
         * [renderItem](https://echarts.apache.org/en/option.html#series-custom.renderItem)
         * method should returns graphic elements definitions.See
         * [renderItem.return](https://echarts.apache.org/en/option.html#series-custom.renderItem.return)
         * .
         *
         * Generally, the main process of
         * [renderItem](https://echarts.apache.org/en/option.html#series-custom.renderItem)
         * is that retrieve value from data and convert them to graphic elements
         * on the current coordinate system. Two methods in
         * [renderItem.arguments.api](https://echarts.apache.org/en/option.html#series-custom.renderItem.arguments.api)
         * are always used in this procedure:
         *
         * + [api.value(...)](https://echarts.apache.org/en/option.html#series-custom.renderItem.arguments.api.value)
         * is used to retrieve value from data.
         * For example, `api.value(0)`
         * retrieve the value of the first dimension in the current data item.
         * + [api.coord(...)](https://echarts.apache.org/en/option.html#series-custom.renderItem.arguments.api.coord)
         * is used to convert data to coordinate.
         * For example, `var point = api.coord([api.value(0),
         * api.value(1)])`
         * converet the data to the point on the current coordinate system.
         *
         * Sometimes
         * [api.size(...)](https://echarts.apache.org/en/option.html#series-custom.renderItem.arguments.api.size)
         * method is needed, which calculates the size on the coordinate system
         * by a given data range.
         *
         * Moreover,
         * [api.style(...)](https://echarts.apache.org/en/option.html#series-custom.renderItem.arguments.api.style)
         * method can be used to set style.
         * It provides not only the style settings specified in
         * [series.itemStyle](https://echarts.apache.org/en/option.html#series-custom.itemStyle)
         * , but also the result of visual mapping.
         * This method can also be called like `api.style({fill:
         * 'green', stroke: 'yellow'})` to override those style settings.
         *
         * **Dimension mapping (by encode and dimension option)**
         *
         * In most cases,
         * [series.encode](https://echarts.apache.org/en/option.html#series-custom.encode)
         * is needed to be specified when using `custom series` serise, which
         * indicate the mapping of dimensions, and then echarts can render appropriate
         * axis by the extent of those data.
         *
         * `encode.tooltip`
         * and `encode.label`
         * can also be specified to define the content of default `tooltip`
         * and `label`.
         * [series.dimensions](https://echarts.apache.org/en/option.html#series-custom.dimensions)
         * can also be specified to defined names of each dimensions, which
         * will be displayed in tooltip.
         *
         * For example:
         *
         * [see doc](https://echarts.apache.org/en/option.html#series-custom)
         *
         * **Controlled by dataZoom**
         *
         * When use `custom series` with
         * [dataZoom](https://echarts.apache.org/en/option.html#dataZoom)
         * ,
         * [dataZoom.filterMode](https://echarts.apache.org/en/option.html#dataZoom.filterMode)
         * usually be set as `'weakFilter'`, which prevent `dataItem` from being
         * filtered when only part of its dimensions are out of the current
         * data window.
         *
         * **Difference between `dataIndex` and `dataIndexInside`**
         *
         * + `dataIndex` is the index of a `dataItem` in the original data.
         * + `dataIndexInside` is the index of a `dataItem` in the current data
         * window (see
         * [dataZoom](https://echarts.apache.org/en/option.html#dataZoom)
         * .
         *
         * [renderItem.arguments.api](https://echarts.apache.org/en/option.html#series-custom.renderItem.arguments.api)
         * uses `dataIndexInside` as the input parameter but not `dataIndex`,
         * because conversion from `dataIndex` to `dataIndexInside` is time-consuming.
         *
         * **Event listener**

             * **
             *
             * + When a dimension corresponds to a value axis (axis.type
             * is `'value'` or `'log'`):
             *
             * The value can be a `number` (like `12`) (can also be a number
             * in a `string` format, like `'12'`).
             *
             * + When a dimension corresponds to a category axis (axis.type
             * is `'category'`):
             *
             * The value should be the ordinal of the axis.data
             * (based on `0`), the string value of the axis.data.
             * For example:
             *
             * [see doc](https://echarts.apache.org/en/option.html#series-custom.custom)
             *

             *

             *
             * + a timestamp, like `1484141700832`, which represents a UTC time.

             * should be considered.
             * + For example: In chrome, `new Date('2012-01-01')` is treated
             * as a Jan 1st 2012 in UTC, while `new Date('2012-1-1')` and `new
             * Date('2012/01/01')` are treated as Jan 1st 2012 in local timezone.
             * In safari `new Date('2012-1-1')` is not supported.
             * + So if you intent to perform `new Date(dateString)`, it is strongly
             * recommended to use a time parse library (e.g.,
             * [moment](https://momentjs.com/)
             * ), or use `echarts.number.parseDate`, or check

             * **Customize a data item:**

             * When needing to customize a data item, it can be set as an object,
             * where property `value` reprensent real value. For example:
             *
             * [see doc](https://echarts.apache.org/en/option.html#series-custom.custom)
             *
             * **Empty value:**
             *
             * `'-'` or `null` or `undefined` or `NaN` can be used to describe
             * that a data item is not exists (ps：_not exist_ does not means
             * its value is `0`).
             *
             * For example, line chart can break when encounter an empty value,
