You can edit the style presets, including the appearance and behaviour of your Dashboard mode by going to
Style>Edit style presets

Another alternative is to re-image the whole dashboard via the Application Styles.
Good thing about it is that you have to do it only once per template - once you're finished , you can save the .xml file, then save it or share with others. Once the other users clicks on it, the new styling option will appear under their Application styles.
This will enable multiple analysts to produce reports for a client that will have the same branding and styling.

Hi Paola,

How do the category data colours work?

I see that there is an option under Data colours that is "recognise colour words" - you can click it on or off. How can I always give yes/ no/ unknown a specific colour in the file irrelevant of which preset I use?

Thanks
Phillipa

You can manually choose the colours for the category fields by going into
Data>Manage fields>Options>Field >Value order,colours,shapes
to select colours for "yes" and "no".

For the numeric fields, you can similarly define the colour range, with min/max and med hue.

If the values in the field contained colour words, such as "red", "yellow", "green" etc, Omniscope could pick it up and apply in visualisation.
