Area charts are categorical charts which are suitable for displaying quantitative data by using continuous lines.
The Area chart is suitable for displaying quantitative data by using continuous lines passing through points defined by the values of their items. The portion of the graph beneath the lines is filled with a particular color for each series. The different colors in an Area chart are useful for emphasizing changes in values coming from several sets of similar data.
The following example demonstrates the Area chart in action.
You can bind the Area series to an array that contains:
- Arrays which represent
- Objects which are also referred to as models.
For more information on how to configure each data-binding mode, refer to the article on binding the Kendo UI Chart to data.
The Area charts feature the following sub-types:
Stacked Area charts are suitable for indicating the proportion of individual values to the total. To set the Area series sub-type, set
Multiple series that are rendered in the same Area chart will overlap one another by default. To avoid that, you can stack these series on top of one another so that the data values at each x-value are summed. In an Area chart, the value for each series will always be stacked relatively to the preceding one.
100% stacked Area charts are suitable for indicating the proportion of individual values as a percentage of the total. To define a stacked Area series sub-type, set
While it is possible to plot negative values in a 100% stacked chart, the results are hard for the user to interpret.
The stepped Area chart is a variation of the Area chart where each data point from the series is connected with vertical and horizontal lines to form a step-like progression. Stepped Area charts are useful for highlighting the increase or decrease in values over time. To define a stepped Area chart, set
A smooth Area chart (spline) chart is a form of Area charts where each data point from the series is connected with a curved line which represents a rough approximation of the missing data points. To define a smooth Area chart, set
