You are now able to customize the colors (actuals, targets, and prior year) in metric graphs. To do this go to your metrics or click on any metric in an element or initiative.
Here you will see a drop-down menu in the top right-hand corner of the graph – “Edit colors”. Here you can select a custom color for each of the graph components.
To add more color options, please refer to “Setting General Parameters” tutorial in the User and Workspace Administration section of the Help Centre. If you are not an admin user, please contact the admin user in your team to assist.
