\title Qt Graphs Theme Overview
\page qtgraphs-overview-theme.html
\brief An overview of the theme in the Qt Graphs module.
A theme is a built-in collection of UI style-related settings applied to all
the visual elements of a graph, such as the colors, fonts, and visibility of
the elements, as well as the strength of the light and ambient light.
Qt Graphs comes with the following predefined themes that can be used as
basis for custom themes:
\list
\li \e {QtGreen} is a theme with green as the base color.
\li \e {QtGreenNeon} is a theme with neon green as the base color.
\li \e {MixSeries} is a theme with mixture of several color series as the base
color.
\li \e {OrangeSeries} is a theme with orange as the base color.
\li \e {YellowSeries} is a theme with yellow as the base color.
\li \e {BlueSeries} is a theme with blue as the base color.
\li \e {PurpleSeries} is a theme with purple as the base color.
\li \e {GreySeries} is a theme with grey as the base color.
\li \e {User defined} is the theme that is meant to be
customized.
\endlist
Custom themes can also be created from scratch.
If a graph displays the data from several data series, some settings can be
specified separately for each series. For example, different gradients can
be specified for different layers of the 3D graph to make it look more
realistic. For an example, see \l{Surface Graph Gallery}.
See \l{GraphsTheme} for details.
