This demo illustrates how XtraCharts processes missing values, which are often caused by skipped tests or measurements.
These values are transformed into empty points represented by breaks in line or area graphs or missing points, bars etc. in other series view types.
In this demo, you're able to change the current series view type via the View Type drop-down list to see how empty points are represented in different series views.
Also, you may change the visibility of the labels shown for each series point.
