Description

Wt is currently lacking a Spectrogram Chart

In addition, the Cartesian chart is tightly coupled with the axis.

A design that entertains an API like that of Qwt would work well.

I provide what I was able to produce in this regard, unfortunately I am out of time and will be unable to work on it further for some time.

While the implementation is incomplete, it is functional.

I attempted to follow Wt naming conventions, though I am sure something is probably wrong. Please modify this in any way you see fit.

For the future:

  • Role based data
    > To allow for location specific tip text
  • Finish the log10 ScaleEngine
  • Port the scale system to WCartesanChart
    > After the axis API matures

Also, the Z-axis is currently a 1px tall image that is generated then scaled in the browser. This should probably be changed as some browsers apply an effect to it as seen in the preview (Firefox).
