Axis step for time values

[User (Legacy)]

I would like to display a chart starting and ending between two time values,

with sensible time steps (0.5 hour, 1 hour etc) between the grid lines. I

have a Gantt chart displaying values between two time values:

chart1.AxisY.LabelsFormat.Format = AxisFormat.Time;

chart1.AxisY.AutoScale = false;

chart1.AxisY.Min = dtHourStart.ToOADate(); // 08:00:00

chart1.AxisY.Max = dtHourStart.AddHours(2).ToOADate(); // 10:00:00

chart1.AxisY.Gridlines = true;

double dStep = 1 / 24;

chart1.AxisY.Step = dStep;

The steps on the axis are as follows:

08:00:00, 08:17:08, 08:34:17, 08:51:25, 09:08:34, 09:25:42, 09:42:51,

10:00:00

How do I set the steps on the axis to be sensible sized units of time (1

hour, 0.5  hour etc)?

Can I set the step size, and let the chart use sensible values for maximum

and minimum?

Thanks.

I've figured it out:

It need double type division, not integer division:

double dStep = 1.0 / 24.0;
