+## FAQ
+
+#### How to save some chart specific state after client have made some changes in charts?
+
+You can use `ChartToTSEvent.UpdateVisualProps` eventType inside `ctx.emitEvent()`.Since the payload type for this event is `JSON` u can just add a key value pair naming `clientState`.
+
+**Sample** -
+```js
+ctx.emitEvent(ChartTOTSEvent.UpdateVisualProps,{
+    visualProps:{
+        clientState:"<req_state_in_string_format>"
+        ...rest_of_visualProp
+    }
+})
+```
+
+- NOTE: client State currently support only string data type.
+
+#### Why my chart is getting re render in a infinte loop?
+Probably you are implementing `update client state` logic inside the the `render` function of `getChartContext`.Since it `render` will be calling `update client state` logic and this logic might again cause `render` this will cause a cyclic call of `render`.Hence,it is advised not to implement it inside `render` function.
+
+
+#### How to add dynamic config for visualPorpEditorDefintion?
+
+Since in our previous implementation of `visualPropEditorDefintion` we provided this as an static object of type `VisualPropEditorDefinition` but with the resent update this is converted function of type `VisualEditorDefinitonSetter` along with `VisualEditorDefintion`.So currently you can provide static config or diynamic config based on use case.
