Bug? AutoRange with Step properties

[Brian]

When I set the AutoRange for an axis and then specify a Step value, the Step value is being ignored.  I would expect the two properties to work in conjunction with each other where the max and min are autoranged but the labels/ticks are marked via the specified Step value. 

I would consider the current behavior a bug.

Hi Brian,

The Step property only works when the AutoRange is set to False. In order to achieve scenario like yours, you could wire up the following method to the LayoutUpdated event.

void radChart1_LayoutUpdated(object sender, EventArgs e)
        {
            var minValue = radChart1.DefaultView.ChartArea.AxisX.ActualMinValue;
            var maxValue = radChart1.DefaultView.ChartArea.AxisX.ActualMaxValue;
            radChart1.DefaultView.ChartArea.AxisX.AutoRange = false;
            radChart1.DefaultView.ChartArea.AxisX.AddRange(minValue, maxValue, 3);
        }

Using this approach you will only change the step with turning off the AutoRange property.

Alternatively you could also use the axis' LabelStep property, which specifies the value indicating that only one out of n-axis labels should be visible, where n is the value of the property.
