Question

I want to represent some data visually, using a visualization component.
Now I want to represent this situation in a visual way:
Suppose I have an web application. I want to get an overview in a visual way about how users are reacting to it.

Say:

• in Day1 I have 2 users: u1, u2
• in Day2 I have 2 users: u1, u2
• In Day3 I have 3 users: u3, u4

It is useless to draw a line chart here. Because I’ll be seeing a constant line. Although I have lost 2 users and gained 2 users in Day3.

How to represent this data in a chart? The chart should give me an idea about: –

• total number of users
• number of users lost
• number of users gained.

Answer 1

Edit: after further thinking, I think this is the best. The other options I listed seem inadequate.

A grouped bar chart like this:

With one bar for each category, number on Y axis and date on X axis.
