The bars aren't constant. I only see mine sometimes. I'm also using less then 1 kwh/hour for the last few months so maybe they have to do with consumption. I'll see if I can get a picture when I read the meter today in a few hours.
If you check the supported meters link here

you'll see a C2S which is what I have. part way down. It has a picture of the bars. Just checking mine I only have a small arrow point to the right at the moment.
you should put together a spreadsheet of your usage then start a thread similar to mine and doax's

put up some details about your house and we can see if anything jumps out. I love looking at those things.
