Timeseries example code is unnecessarily verbose

List tempData = new List();
for (int i = 0; i < size / 2; i++)
tempData.Add(new Data(5));
for (int i = 0; i < size / 2; i++)
tempData.Add(new Data((float)(5 + i * 1.1)));
foreach (var d in tempData)
data.Add(new Data(d.Value));

Simplify the code by removing tempData.
