• Gantt chart (for Drive Utilization reports only -- more information is provided in the section Device reports)

When displaying reports in chart format, the size and appearance of the chart may differ depending on the orientation (portrait or landscape), and the presentation format—that is, whether viewing it in the Console window, or in other file formats, such as PDF, HTML, or PostScript. When displaying reports as charts in document mode, or when printing or exporting to HTML or PostScript, the charts are always displayed on a single page, regardless of their size. As a result, some data and labels may not display. To see full report details, view the chart in interactive mode.

The following table shows a simplified version of chart format options.

Table 1. Report chart formats

Format	Example	Description
Bar		Uses bars to illustrate the different types of data. For example, in a bar chart of a NetWorker Backup Statistics Server Summary report, the vertical bars show the amount of data that are backed up by each server. The additional lines show the corresponding numbers of files and save sets that are backed up by each server. The set of axes that are displayed in the report depends on the type of report. To select various elements for display, select or clear the boxes in the Chart Selector.
Plot		Displays data that are graphed as points along X and Y axes. To select various elements for display, select or clear the boxes in the Chart Selector.
Pie		Display data graphically as a percentage of a circular “pie.” When specifying this chart type from the Console window, the Chart Selector includes a radio button that allows the display of only one element, or axis, at a time. If an additional element is selected, it replaces the first. This limitation does not occur when this chart type is specified from the command prompt: When this chart type is selected from the Console window, all applicable data axes are shown. When this chart type is specified from the command prompt, only the requested information is included.
Stacking Bar		Displays data in a way that enables you to group and measure the data according to more than one category. For example, use of a stacking bar chart to display a report that measures data according to only a single point of focus would display just a simple bar chart. Stacking bar chart reports generally include by in the name, such as by date or by host.
Gantt		When you view a Drive Utilization report as a chart, NMC automatically displays the data as a Gantt chart, and you cannot change the chart type. The Drive Utilization report is the only report that displays data as a Gantt chart. In Save Set view, the x-axis displays the time, and the y-axis displays save set data. Hovering over the chart in Save Set view displays a tool tip that provides this information. Save set name Start time End time Client name Throughput value In Drive view, the x-axis displays the time, and the y-axis displays drive data. Hovering over the chart in Drive View displays a tool tip that provides the following information: Drive Start time End time Throughput value Chart axis selection

Stacking bar charts

In interactive mode, movement of the cursor over a section of stacked color causes a pop-up legend to appear. The legend describes the data that are represented by that color. This chart type is inappropriate for complicated data in document mode, since the cursor does not display a legend describing the data that are represented by that color. Instead, in document mode, select a different chart type (bar, pie, or plot) if the report data is complicated.

When specifying this chart type from the NMC GUI, the Chart Selector includes a radio button that enables the display of only one element, or axis, at a time. If an additional element is selected, it replaces the first. This limitation does not occur when this chart type is specified from the command prompt.

• When you specify this chart type from the NMC GUI, all applicable data axes are shown.
• When you specify this chart type from the command prompt, the gstclreport command only displays the requested information.

To appreciate the different ways in which you can use a stacking bar chart, consider these reports:

• NetWorker Backup Statistics Group Summary by Server — Shows statistics that are broken down by savegroup for each server. Different blocks of color are used for the amounts of data that are backed up by each group within the vertical bars that represent the amount of data backed up by servers.
• NetWorker Backup Statistics Server Summary — Shows data from only one focus, a server-centric point of view. If a stacking bar chart is selected to display a NetWorker Backup Statistics Server Summary, the chart would display solid bars of color to represent the servers. However, there would be no blocks of color within the bars, because the report focuses only on the server level. The result would therefore look like a simple bar chart.
