PHP JPGRAPH - 省略单个数据点

Quick question, I retrieve data from an SQL DB and want to scale it to a customised time range for a line graph. Now the data may not always fill this new scale nicely, hence the line may drop to zero and then ping back up to some random value. Is there a predefined value or similar to force Jpgraph to jump that datapoint and just connect the line with the next 'existing' datapoint.

Thanks in advance :)

    From jpgraph manual:

    Ignore the data point and connect the previous and next data point with the line in a line graph. This is accomplished by specifying the null value as

    '-' - A single hyphen character

    jpgraph是掌握复杂抽象的画图函数。以前用PHP作图时必须要掌握复杂抽象的画图函数，或者借助一些网上下载的画柱形图、饼形图的类来实现。没有一个统一的chart类来实现图表的快速开发。
