CR Enterprise - Custom y-axis labels for line chart

Hi

I have data with a discrete status (STATUS-1...STATUS-5) per day, like

Feb 1: STATUS-1

Feb 2: STATUS-2

Feb 3: STATUS-2

Feb 4: STATUS-1

...

Feb 30: STATUS-4

Feb 31: STATUS-1

This series I'd like to render in a date axis line chart with the daily status ordinals (1-5) on the y-axis.

Now I wonder how I can label the y-axis ticks with the respective STATUS text instead of the ordinal.

Unfortunately, the option "Total (Y) Axis/Axis/AxisLabels/Display Label" is disabled due to the value's numeric nature.

How can I manually overwrite y-axis labels or map them to custom text?

Thanks. Jens
