StatBot is a easy-to-use, very customizable bot that displays the statistics of your server.
What sets this bot apart from the other statistics bots is that it delivers statistics faster, making use of messages and embeds, rather than the traditional channel names. Using messages means that it can also display more statistics in less space.
With a setup wizard, many settings, and many statistics to show, including graphs, there's no reason not to give this bot a try!
