What is the difference between “Select a graph type” options

Hi Friends,
At the bottom of the "Create Graphs for this Host" page, there is a “Select a graph type” dropdown box. What is the difference between the three options, “In/Out Bits (64-bit Counters)”, “In/Out Bits with Total Bandwidth” and “In/Out Byte”?

Try all 3 for the same interface and found out? It's painless

I've tried “In/Out Bits (64-bit Counters)” and “In/Out Bits with Total Bandwidth” in 10G interfaces, and both options can generate correct graphs.
But sometimes, “In/Out Bits (64-bit Counters)” doesn't work, no traffic shown on the graph, but “In/Out Bits with Total Bandwidth” works good; Sometimes, when create a interface with “In/Out Bits (64-bit Counters)”, it doesn't create a new graph in the host page. Then choose “In/Out Bits with Total Bandwidth” and create the same interface, and the host page will appear the two new graphs. It's weird. So I'd like to know what the options exactly mean. I've googled, but didn't find any topics on this.
