New Feature: Multiple Charts For Enhanced Data Comparison
“There’s a new feature on WeatherLink.com that will make it even more fun to compare weather parameters, sensor locations, or even different sensor suites.
Now WeatherLink.com Pro users can set up three different strip charts, showing up to 12 different data points. ”
“Now you can also give your chart a name (click the icon that looks like a pencil). We’ve also streamlined changing each data point’s color, and whether you want to see a bar or line graph of that data point. When you close your charts, they will be saved for next time. ”
