Conceptual Overview

The Plot data class includes the following graph types:

Note: Unlike graphs in other data sets, graphs in the Plot data set are not interchangeable. In other words, a Time Plot data set cannot be used as an X-Y Plot data set.

The Plot data class is used by graphs whose data items are plotted along two axes, like the X-Y graph. Each data item will have at least two data values—an x-value and a y-value (for time graphs, these are called the data and value attributes, respectively, but the concept remains the same). These values indicate the position of the data item along the x-axis and y-axis, respectively. Additionally, Plot data items can have a bubble value, which is used to determine the radius of bubbles in bubble graphs.

Like graphs in the Standard data class, Plot graphs organize data by series. However, they do not organize data by categories. Unless you override a data item's color or symbol, each data item in a series will be shown in the same color and with the same symbol. If the series is being displayed as a line, data items in that series will be connected by a line. There will be one legend item for each series.
