Here are the target output of the chart I want to create.
The chart shows access points channels used and its signal strength. Each access points is represented as spline series.
Here are my progress
As you can see from the above picture, every series is using the first series x values, even when x values for every series is given. It is as if the x values are ignored except for the first series.
Data is organized as follows.
There are 5 series. Each series contains 5 Points. Each points contain 2 values, x and y.
Here are some of the sample data
The x values of Series 2 are totally being ignored.
The source code for the sample, is available here.
