DataChart extends dojox.charting.Chart2D and allows for a simple connection to a data store. When adding a store to a chart, it is necessary to also supply which item property you wish charted. There are two types of properties supported: numbers and arrays of numbers (bubble charts take an array of objects and are not currently supported). If the property is an array, a segment of the array is taken from the end that fits in the display range of the chart. Animated charts are also possible.
Use the spinner fields at the bottom to change the data. The charts listen to store changes an update automatically.
