Non-integer values for x coordinates

[dangdk2]

Hi, Sorry if this is a silly question but so far when the graph plots (line graph or scatter graph) it does not recognise non inter values for the x axis, e.g, if I put x as 1.2 it just plots it at 1. How do I allow for non-integer vlaues for x to be plotted?
Thanks!

To get floating point keys to work you must use Structured data.

If you try to use floating point keys in an array PHP will round the value to an integer. Using structured data means you can send SVGGraph any key values and even repeat key values if the graph type supports it.
