Draw Line chart for non linear X-axis

[shashidhar34]

What did you do?

Trying to plot the line chart with non linear x-axis scale. The sample data set it
(5,100)
(10,200)
(15,100)
(10, 50)
(5, 100)

What did you expect to happen?

The result of the data should be drawn as a Rhombus.

What happened instead?

No line is drawn on the chart. Does the Charts framework expect the x-axis values to be always sorted in ascending order?
