About the Incident Analyzer View
These two views show air quality readings and information in the city of Cagliari, Italy, for the years 2014 and 2015.
There are three monitoring stations: Colle Tuvixeddu, Donoratico and Crespellani classified in suburban (Colle Tuvixeddu) and urban (Donoratico and Crespellani). Use the pie chart to sort by one of the three monitoring stations, station type, station area, and area feature.
The main monitored pollutants are: inhalable dusts, nitrogen dioxide, ozone, carbone monoxide, and benzene. Each station monitors the listed pollutants daily.
You can compare readings for each day of the week, or select a date range.
In view #1, examine the concentrations of two sizes of Particulate Matter and nitrogen dioxide.
In view #2, examine the concentrations of ozone, carbon monoxide, and benzene.

Every incident in the M.App View must be assigned to a theme. The Theme chart shows the distribution of incidents by your specified theme attribute in a pie chart.
You can display incidents from any number of themes in the view.
Single-theme chart Multiple-theme chart
Hover the mouse cursor over a slice of the pie chart to see a tooltip that shows the category name within the theme and the count of incidents.
Click on one of the segments of the theme chart.
Note that the results in the M.App View are filtered to only display the incidents assigned to the category you clicked on.
Click another segment.
Note that the selected incidents are added to the incidents already displayed.
When there is a pull-down menu available, you can select one of the themes in the menu to display any of the interrelated themes. Then, in the pie chart, each segment represents a category within that theme.
Click Reset to display all of the incidents and start over.
Click the maximize icon in the upper-right corner of the chart to expand the chart display to fill the entire window.
Click the minimize icon to restore the chart display to its original size.
Each incident marker can have specific information associated with it. If this information has been configured to be displayed in the View, you can see it using Tooltips.
Click the icon to open the Sidebar panel.
Click on the Preferences entry in the Sidebar panel to expand the contents of this section.
Ensure that the Tooltips option is checked. When it is checked, you can click on pin symbols or cluster markers to view the tooltips. If this option is unchecked, clicking on a cluster marker increases the zoom ratio, and in turn zooms in on the marker that was clicked.
Click on one of the cluster markers.
Notice that a table of tooltips is presented and that the attributes displayed.
Click the Export button to export the contents of this tooltip table to a CSV file.
Click on a single pin symbol.
Notice that a single record is displayed.
Uncheck the Tooltips option. Click on one of the cluster markers.
Notice that this time, the system zooms into the marker you clicked.
Click on another one of the cluster markers until the system no longer zoom in.
At this point, the cluster expands to show all of the incidents at the single location.
In some line charts and bar charts, you can select a range within that chart. Selecting a range is available when the mouse cursor displays as a cross inside the chart.
Click and drag the mouse cursor on the chart to filter the incidents on the map by the selected range.
The map and other charts are updated to show information for the newly selected range.
Click and drag on the range handles to adjust the start or end values.
When a range filter is active, a Reset option is displayed on the chart. Click the Reset option to stop filtering.
