Hi,
We have a requirement to create data label in the format as in the picture attached.
The detailed requirement is as below:
1) label is created by combining series one and 2 data.
2) when the value is negative down arrow is displayed for positive up arrow
3) arrow colors will vary based on percentage (red, amber, green etc)
