h2. 5.1.6 Meta Data Model

This section of document describes how to use meta data model for customizing series visualization. There are 6 MetaData types:

LABEL - used for setting label text

HINT - used for setting hint label

STYLE - used for setting style

DATE_FORMAT - used for setting date format as a pattern string

NUMBER_FORMAT - used for setting number format as a pattern string

BAR_WIDTH - used for setting bar width as double number

PIE_EXPLODE - used for setting PieSeries (both 2D and 3D) sectors' explosion

PIE_HEIGHT - used for setting PieSeries (only 3D) sectors' height

Meta data model can be used either for series or for markers.

Setting MetaDataModel:

//sets a new MetaDataModel object
MetaDataModel meta1 = new MetaDataModel();

Setting parameters for whole series:

//sets for all series label "NewLabel"
meta1.setData(MetaDataType.LABEL, "NewLabel");

Setting parameter for a particular series:

//sets series with index 0 label "Special Series"
meta1.setData(MetaDataType.LABEL,0, "Special Series");

Setting parameters using logical expression: It is possible to set MetaData for particular series, that meet requirements that are defined using logical expressions. These expressions are discussed in more details in LogicalParser chapter. However, here x0 refers to KEYS, x1 to VALUES, x2 to EXTENT and so on.

//sets style for series where KEY is less than 2
meta1.setData(MetaDataType.STYLE, "x0<2", style2);
//sets style for series where VALUE is more than 1
meta1.setData(MetaDataType.LABEL, "x1>1", "Value more than 1");

MetaDataType.LABEL

Setting label “More than avg” for bars where KEY values are greater than 5. In order to use this MetaDataType, LabeledMarker should be used.

meta1.setData(MetaDataType.LABEL, "x0>5", "More than avg");

MetaDataType.HINT

This code formats label string for the VALUES less than 200 to display string “Too little”.:

metaModel.setData(MetaDataType.HINT,"x1<200","Too little");

MetaDataType.STYLE

MetaDataType.STYLE might be used for formatting series colors, transparency and so on, where there is a need to format specific bar, pie's sector or other object.

Styles style = new Styles(); //sets style object
style.getPaintStyle().setBackground(new Color(250,168,23)); //sets background color 
style.getPaintStyle().setForeground(new Color(250,168,23)); //sets foreground color

meta1.setData(MetaDataType.STYLE, 0, style); //sets style for first bar
meta1.setData(MetaDataType.STYLE, 2, style); //sets style for third bar

MetaDataType.DATE_FORMAT

Setting date format for all data points (it is also posible to specify it for a particular point):

metaModel.setData(MetaDataType.DATE_FORMAT,"yy.MM.dd");

MetaDataType.NUMBER_FORMAT

Setting number format for all data points (it is also possible to specify it for a particular point):

metaModel.setData(MetaDataType.NUMBER_FORMAT,"#.00");

MetaDataType.BAR_WIDTH

This sample shows how to set bar width. Here we specify that for VALUES less than 2000 bar width should be 0.06.

meta1.setData(MetaDataType.BAR_WIDTH, "x1<2000", "0.06");
