Similar to other charts, the Chart Styles tab allows the designer to configure how the axes, labels, and legend should display. The configuration for this example shows the dimension of PODate, and multiple metrics which calculate the total for each department.
Scatter
Also known as a scattergram or scatter plot, this chart is used to analyze a set of data in order to look for correlation between a set of variables. Typically, the correlations is dependent, meaning one variable is dependent on the other. Correlation can be positive (increase together), negative (one increases while the other decreases), or no correlation at all. The variable you deem as independent should be plotted on the X axis. In frevvo, the Scatter chart does not show a trend line. Use a Scatter Line to more easily see correlation with a trend line.
For example, perhaps you want to know if there is a correlation between the amount of a Purchase Order and the length of time it takes to process. This chart shows a positive correlation, meaning that as the Grand Total of the PO increases, so does the number of days it takes to process.
In the Chart Styles tab, this chart is configured to show the data label as a tooltip, which avoids cluttering the picture with data but still allows the user to see details on demand.
In this configuration, the independent variable (dimension) is set to calculate the days between the PO date and the submitted date. You might also use the "Age/Duration" metadata here. The metric is simply set to the Grand Total, so that there is a plot point for each submission.
