Summary

This article describes the timeline graph chart report type. 

Table of Contents

This report type can be created by generating a report in the Reports tab in the Fountayn system and selecting ‘Timeline Graph’ from the dropdown on the output screen.

The Timeline Graph produces an interactive time series line graph. The chart is rendered within the browser using Flash. This chart expects a column of dates and any number of data columns which will be charted as separate data sets on the timeline. The column of dates must be chosen by the user as the Data/Date Identifier for the timeline to work properly.

Note: partial dates questions are not supported


The following appear as options for this output type:

Height

This height will be used to size the area where the chart will be drawn. The chart will be sized accordingly within the container. The measurement is in pixels. There are approximately 100 pixels per inch on the average monitor.

Width

This width will be used to size the area where the chart will be drawn. The chart will be sized accordingly within the container. The measurement is in pixels. There are approximately 100 pixels per inch on the average monitor.

Include Header

If set to true (the default), header information will be included at the top of the report (report title, date and time of creation, workgroup, study, and site names). If set to false, only the report title will display above the report.

Data/Date Identifier

Data that will be used to identify the data series is selected using this field selector. For the Timeline Graph, this column must contain date values.

Include Data Table

If True, a table of the data used to generate the chart will be displayed below the chart, sized to the same width.

Include Table Paging

If True (and a table is included with the chart), paging functionality will be included in the data table.

Table Page Size

This value is used to determine the number of results per page if paging is enabled on a data table.

Area Fill Alpha

This number, from 0-100 (inclusive), specifies the alpha of the fill below each line in the graph. 100 means 100% opaque fill, 0 means no fill at all. The fill color is the same as the line above it.

Legend Position

This setting determines whether the colored legend is on the same row with the zoom buttons and the date (‘sameRow’), or on a new row (‘newRow’).
