Thanks for the suggestion but none of the Trendline approaches really work.
The polynomial is the only practical trend method for my data, and it sends the line off to la-la land at the end of the first portion of the plotted line (which is only part of the data, up to the current time, (with historic data from the same hour forward but from yesterday being plotted thereafter as a dotted line formed from another series holding the historic part of the data). The result, while highly artistic, makes for a pretty funky chart. [:-)} I'm just surprised the "function' option doesn't work, as my data is slightly stepped and I was hoping for just a little smoothing. The Y axis data is in 1 degree increments and the X axis data appears on each of the vertical tick lines <https://lh3.googleusercontent.com/-7v5FK4COMfo/VI8pfNFztrI/AAAAAAAAChc/hPkgNlzeE_Q/s1600/chrt.jpg> To get the polynomial to work (ignoring the la-la land issue) would take about a 18 degree equation, (which is too much for the chart API). If smooth would do the little bit of interpalation needed, then I guess I'll just have to live with it, as is.
