Hi,
each time you assign the Record List to the Chart class, the chart will be redrawn automatically. This means, add you new records (your new values) to the record list and set it to the chart class.
You can see that also within the example application 'ChartsDemo', when pressing the button 'New Values': The method 'RandomRecords' creates a set of dummy values within the record list and finally, this list is assigned to the chart. That's all.
Best regards,
Manfred.
