Hello,

i look for a way to "smooth" the graph. I dont like the small corners in it.  
The data came from a array from a mysql database. Hope you know what i mean?!

Though of course as soon as you smooth the data the chart is no longer showing what actually happened.

True, but the sensor reading did. It all depends what you want the graph to show.
