Scatter Plot - Reverse Axis

[Brian]

Hi,

Is it possible to reverse the direction of plot axes?

Eg. plotting depths, zero will be at the top of the plot area.

The primary axis seems to be bound to the x-axis (horizontal axis), eg. in relation to trackball and indicators. Is this correct?

Regards
Brian

Hi Brian,

Thank you for writing.

Although currently this is not supported by RadChartView you can use a custom format provider in order convert the values. Please note that in order this to work properly you should set negative point values:

public class MyCustomFormatProvider : ICustomFormatter, IFormatProvider
{
    public string Format(string format, object arg, IFormatProvider formatProvider)
    {
        int value;

        int.TryParse(Convert.ToString(arg), out value);

        return Math.Abs(value).ToString();
    }

    public object GetFormat(Type formatType)
    {
        if (formatType == typeof(ICustomFormatter))
        {
            return this;
        }

        return null;
    }
}

Also you can change the provider like this:

LinearAxis verticalAxis = radChartView1.Axes.Get<LinearAxis>(1);
verticalAxis.LabelFormatProvider = new MyCustomFormatProvider();

I have attached a sample project to show you how this works in a complete project.

I hope this will be useful. Should you have further questions, I would be glad to help.
