In ArcMap I have made a layer containing two cities and the number of population from 1968-2014. I need help with what symbology to use to show the population development for each city. I have tried various quantities and charts but none shows the development i.e. a graph or something.

Any tips in how to show the development trend clearly?

Attribute table

    What are you trying to show? Change over time? That could be a time-series showing growth each decade, or one map showing % growth since 1968, or any number of other possibilities. What is your end result? A static map? Something interactive? We need some more detail.

  • Yes, change over time like growth/decline since 1968 until 2014. The end result is just a basic map with the two cities highlighted and then the graphics to show change over time.

Perhaps something like percent population change between those two years, categorized by symbol size and color for growth/decline.

  • Okay, I have been looking into this now. It looks like there is no way to use ArcMap for the calculation? That means i need to calculate the percentage difference myself and put the value into the attribute table manualy and that wasn't really how i wanted to do this..

  • You can do that with field calculation. Create a new field, right click and field calculate. Something like this (( population_2014 - population_1968 ) / population_1968) * 100.00

You could try using a bar chart to symbolize your population growth but it might get a bit messy since you are dealing with a large time series. Maybe aggregate population by decade and use the bar chart.

  • Hmm, then i will have to calculate and aggregate manually and i wanted to make a solution were i use ArcMap for everything without needing to add anything more, if you understand what i mean?
