Dynamic Chart values on a time line (like a ticker)

[Former Member]

Hello experts,

can you give me a hint on how to implement a dynamic line chart (one whose values are to be updated every second via a Timer). The timeline is fixed. so the chart should start empty, fill up to the predefined range and then starts shifting the values to the left so that the new data can be appended....

Any help is greatly appreciated.

Hi Holger,

What you can do is use a TimedTrigger UI element.

Assign a context(ctx_int) of type integer to its delay property with some initial value in the init() method.

Assign an action to the onAction event and carry on your logic in this method and at the end of the method increment the value of the context ctx_int.

Hope it helps

Thanks
