A couple comments...
[edit]
The y axis is unlabeled and I can't really think what it might be used for on this chart - but I'm not a physicist. A y-axis label or description would be nice, since it appears to contain information.
The colours of the lines on the chart is misleading since the position in the chart is also related directly to colour. Depicting the actual colours might (or might not) work, but the current use of colour is distracting and confusing.
