Hi,

I want to add label each to the bars in a bar chart. I have made the following bar chart.

This is the sql query I used : select null, 'Hello', rce,rci,cr,vr from employee where empid=1;

I want to add label to each bar on X-axis and make the labels 45 degree aligned with x-axis. Please provide me the SQL query or anything else that is needed for implementing this functionality

Thanks.
