property; see: markerBorderAlpha. When specified on the Source tab, the value
should be between 0 and 1, e.g. 0.8.)
Source tab
The JSON on the Source tab reflects the choices made in the other tabs and, more importantly,
provides the possibility to add in any amCharts configuration option that is unavailable via the
other tab menus. For more information see: "Adding and editing properties manually" on
page741.
Box Formatting dialog
The Box Formatting dialog is accessible by clicking inside a box in the template and then
selecting Format > Box in the menu.
All settings in this dialog are in fact CSS properties. Cascading Style Sheets (CSS) were
originally designed for use with web pages: HTMLfiles. Since Designer templates are HTML
files, they are styled with CSS. To learn how to use CSS in the Designer, see "Styling and
formatting" on page785 and "Styling templates with CSS files" on page786. For information
about specific properties and their options, see W3Schools CSS Reference.
Note
When no unit is added to a geometry value, such as the width, height, top or margin, the
default unit will be added to the value; see "Print preferences" on page911.
Note
Using viewport based units (vw, vh, vmin, vmax) in Print sections is not recommended.
This may cause differences between the preview in the Designer and the printed output.
For information about the different types of Boxes, see "Boxes" on page730.
