The Chart Widget displays a map layer's quantitative attributes as a graphical representation. It is designed to make it easy for users to observe possible patterns and trends in quantitative attribute data, as charts can usually be read more quickly than the raw data from which they are produced.
When the widget is activated, the user needs to do the following:
- Select the data layer from which to retrieve the data.
- Select a graphical spatial search tool with which to draw a boundary around the area on the map that you would like to search.
- Draw, dragging the cursor, an input selection on the map display.
Clicking "Results" (the pie chart icon in the Chart window) will display the Chart widget results. The Chart widget supports the display of four different chart types: bar chart, column chart, line chart, and pie chart. Hover the mouse pointer over a chart element to display additional information.
