chart-view

Arguments: chart-widget

Returns the value of the chart-view property of a chart-widget. The value may be set at creation time by passing the :chart-view initarg, or any time later by calling (setf chart-view).

This property indicates the type of chart to draw. The value may be :bar to draw a bar chart, or :line to draw a line graph. The default value is :line.

The same data are used for either view, though values of types :high-value and :low-value are used only by the bar chart view, and values of type :icon-size are used only by the line graph view. (See set-chart-value and chart-value-returner for information on the various types of data values.)

When the value is :bar, then the bar-chart-view instance in the bar-chart-view property is used to draw a bar chart. When the value is :line, then the line-graph-view instance in the line-graph-view property is used to draw a line graph instead.
