Overview

Area series is a kind of basic chart series that can be used in stocks. To know how to manage Area series in see the Area Chart article.

Data

The data in stocks should be formatted as a table, there are two ways of setting it: as an array of arrays or as an array of objects.

Here is how to set data as an array of arrays, array contains values and then you map the data set to tell the component which column contains values.

// set the data
table = anychart.data.table();
table.addData([
    ['1990-01-01', 248709873],
    ['1995-01-01', 272119084],
    ['2000-01-01', 281421906],
    ['2005-01-01', 299456285],
    ['2010-01-01', 308745538],
    ['2015-01-01', 318914629]
]);
    
// map the data
mapping = table.mapAs();
mapping.addField('value', 1);

The next sample contains the same data arranged as array of objects.

// set the data
table = anychart.data.table('x');
table.addData([
    {x: '1990-01-01', value: 248709873},
    {x: '1995-01-01', value: 272119084},
    {x: '2000-01-01', value: 281421906},
    {x: '2005-01-01', value: 299456285},
    {x: '2010-01-01', value: 308745538},
    {x: '2015-01-01', value: 318914629}
]);
    
// map the data
mapping = table.mapAs({x:'x', value:'value'});

To know more about the data setting in stocks, visit Stock Data tutorial.

Multi series

Basic multi-series chart:

// map the data
mapping_usa = table.mapAs();
mapping_usa.addField('value', 1);
mapping_uk = table.mapAs();
mapping_uk.addField('value', 2);

// set the US series
var series_usa = chart.plot(0).area(mapping_usa);
series_usa.name("USA");

// set the UK series
var series_uk = chart.plot(0).area(mapping_uk);
series_uk.name("UK");

Multiple series on different plots:

// set the US series
var series_usa = chart.plot(0).area(mapping_usa);
series_usa.name("USA");

// set the UK series
var series_uk = chart.plot(1).area(mapping_uk);
series_uk.name("UK");

See the Chart Plots article to know how to manage the plots.

As stocks are intended to show large amounts of data, this data needs to be compressed at some point to be displayed correctly. All information about them can be found in the Data Grouping article.

Switching series type

You can change the type of the series to another compatible type. See the Series Type and series types table.

To switch the series use seriesType() method.

Visualization

Coloring

To change the default colors of the area fill and stroke use fill() and stroke() methods.

To set hatch fill use the hatchFill() method.

// coloring
series_usa.fill("#CC9933");
series_usa.stroke("#FFCC33")

// set the UK series
var series_uk = chart.plot(1).area(mapping_uk);
series_uk.name("UK");

// hatch fill
series_uk.hatchFill("diagonalCross");

Hovered state

WUse the dateTimeHighlighter() method to adjust crosshair.

// crosshair settings
chart.plot(0).dateTimeHighlighter("#663300", 1.5, "6 2", "round");
chart.plot(1).dateTimeHighlighter("#999", 1.5);
