Options

you can specify options for echarts as attribute of gridy-chart.

When xAxis or yAxis specified as string it will be populated from chart driver context by name. Note: some chart types may require at least empty x(y)Axis in options.

	<gridy-chart id="gridyChart2" options='{"xAxis": { "data": "names" }, "yAxis": {}}' type="line" dri="echarts" field-name="Name" field-value="Value" field-group="Group" inner-radius="50" width="400" height="400"></gridy-chart> 

JSONPath expressions on the same chart driver context are also supported for data fields.

attributes

echarts-renderer - renderer parameter for echarts init, possible options: 'svg', 'canvas' (default: 'canvas')

echarts-theme - theme parameter for echarts init (default: null)

value-field passes data extracted from specified field to option.series.data array, if not specified item is passed 'as-is' after mapping
