Thanks for using syncfusion product. We have analyzed your requirement,
Query #1: The option method does not appear to be in the documentation for ejChart
Response : We will be adding those methods in online documentation soon
Query #2: Could you tell me what the 'option' method does and what other methods are available?
Response: The option method can be used to change properties of a chart dynamically after rendering, without creating an instance for chart.
This method can be used to update the dynamic data without refresh the page we can add the data and change the any property using redraw method, with creating an instance of a chart.
Query #3: why it is not in the documentation
Response: option method was used in all JS controls so we cannot add this method under chart. We will consider your request and update our documentation soon
We have prepared a simple sample based on redraw method. Please find the attached sample.
Please let us know if you have any concern.
