update individual data labels

[daniel_in_korea]

Hello,
I would like to design the data labels in my chart individually. For optical reasons it is good to design it like: 'label (value)'.
I know the data label can typed manually, but it is not updated in that case. How can it be designed with automatical update?
Thank you for your help.

How do you mean updated.

Do want to change the content of the Control Label if some conditions met

Such as (example) If "txtInvoiceType" = "CO" then "lblInvoiceType" = "SalesInvoice"

and If "txtInvoiceType" = "CR" then "lblInvoiceType" = "ReturnInvoice"

I mean, if you type the data labels in a chart manually e.g. 'label1 (value1)' and the values change, the value 'value1' remains value1 and does not change. Is there a possibility to do it?
