Quiver has a range of settings to configure the display and format in your analysis. These apply to the current analysis, but not to other analyses that you create.
To open the settings panel, click the cog icon in the side panels bar.
Override default plot colors/labels: These settings allow you to override colors and display names of segments and labels on object charts in your analysis. If changed, local chart display settings take priority over global settings.
By default, data from different object sets on the same chart will be in different colors; similarly, different segments in a segmented chart will also be colored differently. Without intervention, these colors will be assigned to ensure maximum contrast between categories. You can set global color overrides if desired, whether because of color preferences or because you would like certain segments to be colored the same on all charts throughout the analysis.
Note that to assign a specific color to each bar in a bar chart, you first need to segment your series by the same property that you grouped by.
