After(!) adding a point at a non-zero x-value or setting chart.SuppressExceptions = true you can use these properties for a Chartarea ca: ca.AxisX.IsLogarithmic = true; ca.AxisX.LogarithmBase = 10; // with 10 as the base it will go to 1, 10, 100, 1000.. ca.AxisX.Interval = 1; // this adds 4 tickmarks into each interval: ca.AxisX.MajorTickMark.Interval = … Read more
