It missed a day, the SMS text didn't get sent by the gauge or some other issue.
But what happened is the graph joined the dots between the two days, giving a straight line. Where as in reality that part of the graph should be blank.
I have built up a list of issues with the current graphs and I'm in the process of building an entirely new graphing system. Yet again, like most of my projects, it will be done when i have time, the rivers are dry, enthusiasm is high, there isn't anything good on TV.
