MCharts library is designed using a Model-View-Controller architecture. Model part is represented by data management components, View is represented by visual components and Controller is represented by plug-ins which determines the “control flow” of the system and process incoming events from the View.
Figure 5.1 Main Chart Elements Demonstration
MCharts structural elements are divided into several groups:
- data management elements contains data, which is shown on chart, for example ChartDataModel
- chart properties (style sheets) are responsible for visual formatting of chart elements - Axis, Grid and so on, for instance Styles
- axes controls allow modifying axis properties
- legend identifies colors and titles that are assigned to the data series in a chart
- chart containers isolate the physical medium for chart output, for example JChartPanel
- views are used for decorating chart with titles or footers and for displaying multiple charts on one page
- plug-ins add features to chart, for example DrillDown, GIFEncoderPlugin plug-ins
