The series displayed on charts generated with GraphApplet have
data points distributed in a regular sequence that follows labels progression.
This sequence is continuous, in that for each label there is always a
visible data point.
In certain conditions, however, there might be series with a discontinuous sequence
of values, in which case gaps have to be inserted where no data points are to be
displayed.
A continuous sequence of values must always be passed to JetChart series, despite there
being gaps of data coming from the data source. In such case it is necessary to fill the
gaps with arbitrary values, as zeros. For instance, let's suppose a chart displays
10 labels, and a data source doesn't return values corresponding to the second and
fourth labels, but null data instead. Even in this case the parameter
seriex_values must take arbitrary values in the second and fourth positions,
and the parameter seriex_coordinatesstatus has to be used to indicate that
the second and fourth data points must not be displayed.
The seriex_coordinatesstatus parameter takes a sequence
of binary digits specifying what data points shall be displayed or not.
A value of '0' means that the corresponding data point is hidden, whereas a value of
'1' keeps the data point visible.
The parameter seriex_hiddenlineson can be used to specify whether the line fragments
of a line series with hidden points shall be connected to each other or not.
Except for area series, all the other series displayed by GraphApplet support setting the
coordinates status.
The following example displays a line series with hidden data points. The parameter
'seriex_hiddenlineson' is used to connect discontinuous segments of line.
