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
