Pressure graph units

The pressure graph y axis units says hPa but the the numbers seem to be in Pa (multiplied by 100) on the web page.

@io53 check it

Thanks for the bug report. You are right, its indeed off by 2 orders of magnitude. I created an issue about it

While you’re at it, please have a look at the y axis values. If the range of measurement values is small, the y axis shows unnecessarily many tick marks, with values that are well beyond the accuracy of RuuviTags.

This problem is relevant when a user starts using the service but when time goes by, the range of measurement values increases, and the user does not see it anymore. Still, it would be nice to fix this. Also, I assume the problem may become visible when the user zooms teh y axis.
