Rectangle
Overview
The Rectangle annotation allows you to add a rectangle or a square to a chart.
This article explains how to add a Rectangle and configure its basic and visual settings. You can find more settings and other useful information in the articles describing annotations in general:

Basic Settings
To add a Rectangle annotation to a chart, call the rectangle() method of the annotations() object.
Next, use the xAnchor(), valueAnchor(), secondXAnchor(), and secondValueAnchor() methods to set 2 points that determine the position of the rectangle. Usually, the most convenient way to do this is object notation:
// create a stock chart
chart = anychart.stock();
// create a plot on the chart
var plot = chart.plot(0);
// access the annotations() object of the plot to work with annotations
var controller = plot.annotations();
// create a Rectangle annotation
controller.rectangle({
xAnchor: "2006-11-19",
valueAnchor: 29.84,
secondXAnchor: "2007-03-25",
secondValueAnchor: 25.11
});
This is how it looks like:
Appearance
The appearance settings of a Rectangle annotation can be configured in three states: normal, hover, and selected. Use the following methods:
Combine them with these methods:
You can also use object notation to specify the settings.
In the sample below, there are two Rectangle annotations with some of the visual settings configured (by using an object in the first case and methods in the second):
// create the first Rectangle annotation and configure its visual settings
var rectangle1 = controller.rectangle({
xAnchor: "2006-11-19",
valueAnchor: 29.84,
secondXAnchor: "2007-03-25",
secondValueAnchor: 25.11,
hovered: {
fill: "#398cae 0.3",
stroke: "2 #ff0000"
},
selected: {
fill: "#398cae 0.3",
hatchFill: "forward-diagonal",
stroke: "4 #ff0000"
}
});
// create the second Rectangle annotation
var rectangle2 = controller.rectangle();
// set the position of the second annotation
rectangle2.xAnchor("2005-11-20");
rectangle2.valueAnchor(15.55);
rectangle2.secondXAnchor("2007-02-25");
rectangle2.secondValueAnchor(23.30);
// configure the visual settings of the second annotation
rectangle2.normal().fill("none");
rectangle2.normal().stroke("#006600", 1, "10 2");
rectangle2.hovered().stroke("#00b300", 2, "10 2");
rectangle2.selected().stroke("#00b300", 4, "10 2");
