10.1.1              Chart Area

Chart area represents a chart area on the chart image. Within any given chart, the inner plot position is the rectangular area, inside the x and y-axis lines, where the data points are drawn. The plot position is the rectangular area that encompasses the inner plot position, the tick marks, and the axis labels. The chart area is the rectangular area that encompasses the plot position, the tick marks, the axis labels and the axis titles on the chart.

When you use Shape chart types, which include pie, doughnut, funnel, pyramid, polar, and radar charts, the inner plotting position defines the size of the chart type shape. A Chart Area Objekt:

·         Uses one distinct inner plotting area.

·         Is used to plot one or more chart series.

·         Has primary and secondary x and y-axes, except for pie and doughnut chart types.

10.1.2              Data Series

The data series or chart series are used to show data as a chart type (bar, column, line etc.). A data series stores data point objects and also stores attributes of the data series. For example, a data series has a color attribute, background image attribute, background gradient attribute, and so forth.

The data point objects that belong to a series also have their own attributes. Normally, if the same attribute is set for a data point and the series to which it belongs, the data point attribute has precedence. When a series is created, it is automatically assigned to the chart area object named "Default", or to the first available chart area in the chart area collection if the "Default" objects does not exist.
