Hi, in runtime I can see that X-axis limits of my chart (minimum and maximum) are automatically changed as I insert points. That's nice. So I came to an idea to change that minimum and maximum values. It worked. But as soon as I wanted to return (at runtime) to auto I came across some problems. First I discovered that when auto scaling is activated this values are:
So I then (at runtime) returned this values to Double.NegativeInfinity hoping that Chart will then automatically (again) scale X axis. Instead I got exception:Code:myChart.ChartAreas(0).AxisX.Maximum = Double.NegativeInfinity
myChart.ChartAreas(0).AxisX.Minimum = Double.NegativeInfinity
Stack:Code:Axis Object - The minimum value of the axis is greater than the largest data point value.
As you can see from Call stack, exception did not originated from my code, but was definitely caused by this code:Code:at System.Windows.Forms.DataVisualization.Charting.Axis.EstimateAxis(Double& minimumValue, Double& maximumValue, Boolean autoMaximum, Boolean autoMinimum)

Note that default values ARE Double.NegativeInfinity!Code:myChart.ChartAreas(0).AxisX.Maximum = 150
myChart.ChartAreas(0).AxisX.Minimum = 50
myChart.ChartAreas(0).AxisX.Maximum = Double.NegativeInfinity
myChart.ChartAreas(0).AxisX.Minimum = Double.NegativeInfinity
Any help is greatly appreciated.
