The hyperbolic spiral, also called the inverse spiral, originated with Pierre Varignon in 1704 and was studied by Johann Bernoulli between 1710 and 1713. It begins at an infinite distance from the pole in the center, it winds faster and faster around as it approaches the pole, the distance from any point to the pole, following the curve, is infinite.


Create a Hyperbolic spiral programmatically (C#)
 Copy imageCopy
// Setup our X coordinates.
DateTime startDate = DateTime.Now;
DateTime lastWeek = startDate.AddDays(-7);

// Create the Hyperbolic Spiral object
ChartHyperbolicSpiral spiral = new ChartHyperbolicSpiral(new ChartPoint(startDate, 20.00), new ChartPoint(lastWeek, 25.00));

// Add this object to the chart.  "symbol" would equal the current symbol object in the system.
ChartObjects.Add(symbol, spiral);
