showing Percentage work completed on the bar graph

[info12suchi]

Hi,

I am trying to Chart/graph the data.
Vw_rp_job_status.CARD_TYPE on X-axis
And the Percentage of the work completion on Y-axis.

Here is the formula for the Percentage_work_Completed.

numbervar WIP_Cards := (Sum ({@QA Final}, {Vw_rp_job_status.CARD_TYPE})+
Sum ({@Work Complete}, {Vw_rp_job_status.CARD_TYPE})+
Sum ({@Audit Comp}, {Vw_rp_job_status.CARD_TYPE}));

numbervar Total_Cards := WIP_Cards + Sum ({@Open}, {Vw_rp_job_status.CARD_TYPE});

WIP_Cards%Total_Cards


But When I am trying to right click on the chart and modify the SHOW in the DATA tab. It is not showing the Percentage formula in the drop down.

Please help me on this.
