how to visualize inflow and outflow of data

suppose there're 3 items with their respective vol:

a b c
12 20 28

each has a certain vol added and subtracted

   a b c
added 3 5 12
subtracted 2 7 8

What format can best visualize the dynamics of inflow and outflow as such, even if number of items are far more than 3?

As I commented above, one visualization you could use would actually be a combination of a line chart, to show the running overall trend of the volume, along with a bar for each day, to show the positive or negative gain for that day. In the financial world, there is already such a chart, called a candlestick chart. Here is sample of one:

enter image description here

The way to read the chart is that the circle is where the trend ended in that year. But the start of the bar (below for losses, above for gains) is where the value actually started in that year. This is a convenient way to convey both pieces of information which you want to get across to your audience.
