Chart Map
Certain kinds of information, such as a range of chemicals in a river, are
displayed with a chart.The components of the chart correspond to data
attributes which you specify, and the size of each section of the chart is
determined by the value of each data attribute. Chart maps allow you to
display the values of many data attributes at once.This is a particularly
powerful tool because you can clearly show the relationships of different
but related data with one clear symbol. For instance, you can map the
income distribution by income ranges for a given population and clearly
state which areas are dominated by a particular income.
1. Bar Charts
When you present information in bar charts, you can control the
width, and minimum and maximum height of each chart symbol.You can
change these properties in the properties window.
2. Pie Charts
Pie charts begin with the first field you have chosen and rotate counterclockwise
from the three o’clock position.A size field can be set in the
Pie Chart Properties window, the values of which control the size of each
feature’s pie chart symbol.The minimum and maximum radius for the pie
chart symbols can be set in the Pie Chart Properties window as well.
