For the service pack of the Q1 2015 release, we kept on the initiative of improving RadChartView where we addressed a couple more feedback items on the control, most interesting of which is the new feature: scale breaks

A scale break is a clear visual indication drawn across the plotting area of a chart to denote a break in continuity between the high and low values on a value axis (usually the vertical, or y-axis). 

Scale breaks are supported in all of the cartesian series, except the financial series. Here is a list of the supported series: Area, Bar, Line, Stepline, Scatter, ScatterLine, Bubble, ScatterArea, Range, RangeBar.

To add a scale break, you need to create an object(s) of type AxisScaleBreak and add it to the ScaleBreaks collection of the desired axis. 
List<AxisScaleBreak> breaks = new List<AxisScaleBreak>();
breaks.Add(new AxisScaleBreak("Break1", "Feb", "Apr"));
breaks.Add(new AxisScaleBreak("Break2", "Sep", "Nov"));
foreach (AxisScaleBreak scaleBreak in breaks)

The API for customizing the scale break consist of the following properties:
  • Style: Enables you to change the visual style of the scale breaks. Three different styles are available: 
    • Straight
    • Waved
    • Ragged
  • BackColor: Enables you to change the background of the scale break. 
  • BorderColor: Controls the color of the scale break lines. 
  • Size: Controls the distance between the scale break lines.
For example, here is how to change the style of the scale breaks of the HorizontalAxis:
lineSeries.HorizontalAxis.ScaleBreakStyle = ScaleBreakStyle.Ragged;

For a list of the improvements made in Q1 2015 SP1, you can have a look at our release notes.

Make sure you download the new release from your Telerik account, or if you don’t have one, you can download a trial.
