I’m wondering if it’s possible to create a candlestick chart with “real-time” values.

For Example:
I want to create a chart with 8 x values and constantly changing y values (about once a minute). Is there a way to change the y value of these bars (Currently, I’m “deleting” all of them and draw the new ones afterwards – guess that’s not the best option?)

Thanks in advance!

Hello there,

You may be interested in this answer on Fixing Data Values that Arrive in Non Sorted DateTime Order as this covers the DataSeries API, including ability to Add, Remove, Insert, Update points in detail.

We also have an example on Real Time Ticking Stock Charts which shows how to Update the latest bar and scroll the chart bar-by-bar in a realtime stock chart example.

Best regards,
