Re: [racket-users] Adding interactive overlays to racket plots

[Alex Harsanyi]

About a month ago, the changes for the plot overlays were merged into the 
main plot repository and will be available in the next Racket release.  
Based on feedback from Ben Greenman, the implementation is different than 
my original prototype, but it is more flexible -- thanks to Ben for 
suggestions and support in getting this merged.

While the changes have not made it into a Racket release, I wrote a short 
blog post about how to implement some common plot overlay use cases, while 
the idea is still fresh in my head.  You can find it here:

Best Regards,
Alex.

This is beautiful. Thank you very much!

Would you consider including that content into the docs themselves (as
examples)?

This is awesome! Thanks so much for doing this, I'm sure it's going to be
very handy.

Re: [racket-users] Adding interactive overlays to racket plots

Hi Matthias,

I updated the plot package to cover all the cases I had in mind for plot 
overlays and also updated my application to make use of these features, 
just to make sure that they are adequate.

The pull request is here: https://github.com/racket/plot/pull/32, it would 
be good if I could get some feedback if my approach OK, or what needs to be 
changed.  What is missing is the documentation, but I would like to leave 
that until after the code is considered OK.  I wrote up some notes about 
the API here: https://github.com/alex-hhh/plot/wiki/overlays-notes

I also did a write-up of the features, as well as some screenshots to 
illustrate what can be done with the new functionality.  You can find that 
here: 
https://alex-hhh.github.io/2018/02/interactive-overlays-with-the-racket-plot-package.html

Best Regards,
Alex.

Yes, definitely!

[racket-users] Adding interactive overlays to racket plots

[Alex Harsanyi]

The racket plot package produces interactive snip% objects which allow 
zooming of the plot area. While this is a cool and sometimes useful 
feature, the functionality is hard coded in the plot-snip% class inside the 
package. I would like to extend the package to allow the user to customize 
the interactive features of the plot -- most of the graphing packages for 
the web support the display of additional information when the user hovers 
the mouse over the plot.

I have built a prototype implementation of adding interactive overlays to 
plot snips, as shown in the image below, and I would like to ask if there 
is interest in adding such a feature to the plot package distributed with 
racket.

At this point, the code is at a "proof of concept" stage, but ultimately, I 
will add interactive features to the plots in my application and they will 
be more complex than just showing the value of a function at a cursor 
location. As part of that experience, I will better understand what actual 
features I need, and hope to refine this interface. I am also looking for 
feedback, in particular if this would be the right approach for doing this.

The prototype implementation is here: 
https://github.com/alex-hhh/plot/tree/ah/interactive-overlays

The code to generate the plot below is here: 
https://gist.github.com/alex-hhh/64f8af9c4bd5b5c65ada62dd9157e938 

As it is implemented now, unless a "hover callback" is added to the plot 
snip, the snip behaves as before, allowing zoom and unzoom when the mouse 
is dragged over the plot area.






Best Regards,
Alex.
