Type of Data in ASP.NET Core Range Navigator control

Numeric

Numeric scale is used to represent the numeric values of data in a chart. By default, the valueType of a range navigator is Double.

           List <data> dataSource = new List<data>
            {
                new data {  y = 12, y1 = 28 },
                new data {  y = 34, y1 = 44 },
                new data {  y = 45, y1 = 48 },
                new data {  y = 56, y1 = 50 },
                new data {  y = 67, y1 = 66 },
                new data {  y = 78, y1 = 78 },
                new data {  y = 89, y1 = 84 },
            };
            ViewBag.dataSource = dataSource;
            return View();

        {
            public double y;
            public double y1;
        }

Range

Minimum and maximum of the Range navigator will be calculated automatically based on the provided data. You can also customize the range using the minimum, maximum, and interval properties.

tagHelper
range.cs
@{
    var value = new object[] { 20,50 };
}
 <ejs-rangenavigator id="rangeNavigator" valueType="Double" minimum=10 maximum=400 interval="10" value="value" >

                </e-rangenavigator-rangenavigatorseriescollection>
</ejs-rangenavigator>
public IActionResult Index()
        {
           List <data> dataSource = new List<data>
            {
                new data {  y = 12, y1 = 28 },
                new data {  y = 34, y1 = 44 },
                new data {  y = 45, y1 = 48 },
                new data {  y = 56, y1 = 50 },
                new data {  y = 67, y1 = 66 },
                new data {  y = 78, y1 = 78 },
                new data {  y = 89, y1 = 84 },
            };
            ViewBag.dataSource = dataSource;
            return View();
        }
        public class data
        {
            public double y;
            public double y1;
        }

Label Format

Numeric labels can be formatted using the labelFormat property.

Numeric labels support all globalized formats.

tagHelper
format.cs
<ejs-rangenavigator id="rangeNavigator" valueType="Double" labelFormat="n1"  >
                <e-rangenavigator-rangenavigatorseriescollection>

                    </e-rangenavigator-rangenavigatorseries>
                </e-rangenavigator-rangenavigatorseriescollection>
</ejs-rangenavigator>
public IActionResult Index()
        {
           List <data> dataSource = new List<data>
            {
                new data {  y = 12, y1 = 28 },
                new data {  y = 34, y1 = 44 },
                new data {  y = 45, y1 = 48 },
                new data {  y = 56, y1 = 50 },
                new data {  y = 67, y1 = 66 },
                new data {  y = 78, y1 = 78 },
                new data {  y = 89, y1 = 84 },
            };
            ViewBag.dataSource = dataSource;
            return View();
        }
        public class data
        {
            public double y;
            public double y1;
        }

The following table describes the result of applying some commonly used label formats on numeric values.

Label Value Label Format property value Result Description
1000 n1 1000.0 The Number is rounded to 1 decimal place
1000 n2 1000.00 The Number is rounded to 2 decimal place
1000 n3 1000.000 The Number is rounded to 3 decimal place
0.01 p1 1.0% The Number is converted to percentage with 1 decimal place
0.01 p2 1.00% The Number is converted to percentage with 2 decimal place
0.01 p3 1.000% The Number is converted to percentage with 3 decimal place

1000 c2 $1,000.00 The Currency symbol is appended to number and number is rounded to 2 decimal place

Custom Label Format

The range navigator also supports custom label formats using placeholders such as {value}$, in which, the value represent the axis label, e.g. 20$.

            public double y1;
        }

Logarithmic Axis

Logarithmic supports logarithmic scale, and it is used to visualize data when the Range navigator has numerical values in both lower (e.g.: 10-6) and higher (e.g.: 106) orders of magnitude.

            public double y1;
        }

Note: Date-time Range navigator supports date-time scale and displays date-time values as a labels in the specified format.

Interval Customization

Date-time intervals can be customized using the interval and intervalType properties of the range navigator. For example, when you set interval as 2 and intervalType as years, the interval is considered as 2 years. Date-time supports the following interval types:

  • Auto
  • Years
  • Quarter
  • Months
  • Weeks
  • Days
  • Hours
  • Minutes

You can format and parse the date to all globalize format using labelFormat property in an axis.

The following table describes the result of applying some common date time formats to the labelFormat property

Label Value Label Format Property Value Result Description
