You want to represent four variables:
- damaged surface area in the residential areas [km2]
- number of living units affected
- number of people affected
- damage [euroes]
All these variables are absolute values.
Assuming you have polygon layer please take into account:
Absolute data should not be used in choropleth mapping. Do not use a color ramp to color the area (fill color) of a polygon. So do not do this if you want to show “number of people affected”: Color ramp: bright red to dark red
Instead of showing absolute values you should show relative values: You can divide the “number of people affected” by the “number of people living in this area”. ArcView is able to calculate this on-the-fly (layer properties dialog). Then you can use a color ramp to color the area (fill color) of a polygon.
If you want to show absoute values (“number of people affected”) you have to use dot distribution or proportional symbols.
I see no possibility to use charts. I.e. there is no sense to show the “number of people affected” and the “damage [euros]” together in one pie chart.
I think that it's too much to show all your 4 values in one map. Often it is better to make several maps.
