Multiple Display Libraries dialog
You use the Multiple Display Libraries dialog to specify which code libraries to use to colour tasks on the bar chart and in the calendar view. Tasks are coloured according to the codes from the selected libraries that have been assigned to them - or to their bars, depending on whether you have clicked the Use on tasks or Use on bars radio button on the Tasks tab of the Format Bar Chart dialog.
You can use more than one code library at a time to colour tasks. If you do this and a task or bar is assigned codes from more than one of these libraries, the order in which the code libraries appear in the Show libraries in this order field on this dialog determines which code is used to colour the task. Code libraries at the top of the list take priority over those lower down the list. If a bar or task is assigned a code from more than one display library, the task appearance is taken from the library that appears nearest the top of this list.

To access the Multiple Display Libraries dialog, either:
- Click the Display Libraries button on the Tasks tab of the Format Bar Chart dialog.
- Right-click the Code Libraries library in the project view and select Multiple Display Libraries.
- Click the Display Libraries button on the General tab of the Format Calendar View dialog.

Remove | Click this button to move a code library that is currently selected in the Show libraries in this order field to the Available libraries field, thereby choosing not to display it. |
Show libraries in this order |
A list of the code libraries that are currently displayed. Click a code library in this field to select it.
Code libraries at the top of the list take priority over those lower down the list. If a bar or task is assigned a code from more than one display library, the task appearance is taken from the library that appears nearest the top of this list. |
Up | Click this button to move the code library that is currently selected in the Show libraries in this order field higher up in the list of priority. |
Down | Click this button move the code library that is currently selected in the Show libraries in this order field lower down in the list of priority. |
How do I...

- Select the code library that you want to display in the Available libraries field.
- Click Add. The code library appears in the Show libraries in this order field.

- Select the code library that you want to remove from the display in the Show libraries in this order field.
- Click Remove. The code library appears in the Available libraries field.

- Select the code library you want to configure in the Show libraries in this order field.
- Click Up to move the item towards the top of the list - and therefore higher up in the list of priority - or click Down to move it towards the bottom of the list - and therefore lower down in the list of priority.
Code libraries at the top of the list take priority over those lower down the list. If a bar or task is assigned a code from more than one display library, the task appearance is taken from the library that appears nearest the top of this list.
