And X-Axis is time, it has to be String.

Hi Steven,

You mentioned "X-Axis is time". I assume you mean the x-coordinates of your data points is "time" as according to your programming language. (I am not sure what is your programming language. In .NET, "time" means a System.DateTime object. In Java, "time" means a java.util.Date object. In other programming langauges, "time" can mean other things.) If this is the case, the scatter points can be added as (in VB.NET):

c.addScatterLayer(anArrayOfDateTime, anArrayOfNumbers, .....)

For the x-axis, you can let ChartDirector auto-scale the x-axis, or you can specify the scale using Axis.setDateScale. You can configure the labelling format by using Axis.setLabelFormat. For example:

c.xAxis().setLabelFormat("{value|hh:nn:ss}")

If the above does not solve the problem, please let me know what is your programming language, and what is the type of x-coordinate. (Please use programming language to express the type of x-coordinate, not human language.)
