A line chart is a chart that shows information as a series of data points connected by straight line segments.
The line chart is very common in many fields. As a rule, it is used to emphasize trends in data over equal time intervals, such as months, quarters, fiscal years, and so on.
This article explains how to create a basic Line chart as well as configure settings that are specific to the type. You can also see the table below to get a brief overview of the Line chart's characteristics:
|Modules||Core + Basic Cartesian / Base|
|Data Fields||x, value|
|Error Bars||Line Chart with Error Bars|
|SUPPORTED CHART PLOTS|
|Polar||Polar Line, Polyline|
|Chartopedia: Line Chart|
Alternatively, you can use the Base module, which includes, among other things, the two modules mentioned above:

To create a Line chart, use the anychart.line() chart constructor. If you pass the data to this chart constructor, it creates a line series.
To create a Line series explicitly, call the line() method.
The following sample demonstrates how a basic Line chart is created:
// create data var data = [ ["January", 10000], ["February", 12000], ["March", 18000], ["April", 11000], ["May", 9000] ]; // create a chart chart = anychart.line(); // create a line series and set the data var series = chart.line(data); // set the container id chart.container("container"); // initiate drawing the chart chart.draw();
In AnyChart there are many settings that are configured in the same way for all chart types, including the Line chart (for example, legend and interactivity settings).
Read the overview of general settings: General Settings.
In the sample below, there are two Line series with appearance settings configured:
// create the first series var series1 = chart.line(seriesData_1); // configure the visual settings of the first series series1.normal().stroke("#00cc99", 1, "10 5", "round"); series1.hovered().stroke("#00cc99", 2, "10 5", "round"); series1.selected().stroke("#00cc99", 4, "10 5", "round"); // create the second series var series2 = chart.line(seriesData_2); // configure the visual settings of the second series series2.normal().stroke("#0066cc"); series2.hovered().stroke("#0066cc", 2); series2.selected().stroke("#0066cc", 4);
Labels are text or image elements that can be placed anywhere on any chart (you can enable them on a whole series or in a single point). For text labels, font settings and text formatters are available.
A Tooltip is a text box displayed when a point on a chart is hovered over. There is a number of visual and other settings available: for example, you can edit the text by using font settings and text formatters, change the style of background, adjust the position of a tooltip, and so on.
Most types of series in AnyChart can be drawn both in horizontal and vertical orientation: Vertical Charts.
