Custom text for 'No value' in Line chart of sapui5

Hi,

I am working on sapui5 Line chart in viz package.

I want to know the way to customize the 'No value' text in Line chart implemented.

Here is the screenshot for your reference

Here I want to replace 'No value' text for Usage (in kwh) value with some customized text/value.

Can anyone please suggest whether this can be implemented and the way of implementation if it is possible.

Thanks in advance,

Ramana.
