The Chart Builder in Crash Query is designed to help users create custom downloadable charts to visualize the data contained in a Query. Each custom chart can utilize either the Crash Cost Measure, which uses your agency’s default KABCO cost calculations to determine the cost of the crashes for each grouping or the Crash Count Measure which calculates the total number of crashes for each grouping.
Charts are saved with any Query and can be easily referenced, downloaded, or included in Crash Summary or Comparison reports, from saved Crash Queries.
There are six chart types available in the Chart Builder: Bar, Stacked Bar, Grouped Bar, Line, Pie, and Pivot Table.
The Bar Chart allows users to visualize a measure and a single grouping in a vertical bar chart.
The Bar Chart is downloadable as a PNG image file.
The Stacked Bar Chart allows users to visualize a measure and two groupings in a stacked vertical bar chart. The Stacked Bar Chart is downloadable as a PNG image file.
The Grouped Bar Chart allows users to visualize a measure and two groupings in a vertical grouped bar chart. The Grouped Bar Chart is downloadable as a PNG image file.
The Line Chart allows users to visualize a measure and a single grouping in a vertical line chart. The Line Chart is downloadable as a PNG image file.
The Pie Chart allows users to visualize a measure and a single grouping in a pie chart. The Pie Chart is downloadable as a PNG image file.
The Pivot Table chart allows users to visualize a measure and up to three groupings in a Pivot Table. The Pivot Table is downloadable as a CSV file.
When creating a Pivot Table, the first grouping will define the rows of the table, the second grouping will define the columns, and the third grouping will define a second row. In the example below, the first grouping is by year, the second grouping is by city, and the third grouping is by bicyclist involved.
Chart Builder Sidebar
When creating a custom chart, the chart builder sidebar contains various formatting adjustments and customizations that can be applied to each chart. The Chart Builder Sidebar contains the following headings:
Under the Sorting heading, users can adjust the order in which the values in their chart appear, either ascending or descending.
Users can also determine if the sorting should be applied to the measure or the grouping.
The number of values to be displayed can be selected using the text entry box. This will display the top identified number of values that meet the sorting criteria. The Bar, Stacked Bar, Grouped Bar, and Line Chart types can all display a maximum of 50 values, the Pie Chart can display a maximum of 15 values.
In the Pie Chart, users can also select to include an “Other” slicer, which will include all other values not visualized in the pie chart as a slice labeled “Other”.
Available for the following Chart Types: Bar, Stacked Bar, Grouped Bar, Line, Pie.
Vertical and Horizontal Axis
The Vertical and Horizontal Axis headings allow users to add a custom title to either axis. This custom text will appear along the outside of either the vertical, or horizontal axis in the chart.
Additionally, users can check the Show tick Labels box, which will display label values along the horizontal or vertical axis. The formatting of the tick labels can be customized by clicking on the gear icon to the right of the checkbox. This will allow users to add a prefix/suffix, or change the number or date/time formatting of the labels.
