updating a highcharts plot through user-selected datapoints about highcharter HOT 3 CLOSED

HI @SelimRABOUDI,

I think you can program this chart handling the right highcharts events with javascript and updating the chart data. But I think this need more highcharts/javascript knowledge. I finded this example http://jsfiddle.net/highcharts/nsuA6/ and modified into this http://jsfiddle.net/tznwoc09/. It can be a start point to work. An alternative solution will be using shiny but maybe you need a standalone chart.

But going further. I think this funcionality is really interesting, for example when you are binning a variable and see rate from other varible in each group and you visualize and get the new categories/grups back to R. It can be treated like a shinygadet http://shiny.rstudio.com/articles/gadgets.html. It sounds interesting.

Anyway I think this can be achieve with highcharter but it will be need a lot of this things https://github.com/jbkunst/shiny-apps/blob/master/highcharter/server.R#L152.

So answer your points.

1. Yes, its doable.
2. Yes, because highcharter is a wrapper so if you can code or see and example using just js you can translate the code to R.
3. I dont see any limitation. In my case the limitation is my highchart expertise using events XD.

I think this is not a feature, It need to be coded. Maybe after the new release of highcharter I will have time to work in this idea (chart and gadget). If you can start It would be happy if you show me and update ;)!

Tell me what you think.

Hi Joshua,

Thanks for your reply

Yes, the output I'm after is indeed a Shiny Gadget (as a RStudio Addin), where a user could create groups through window dragging, and get the corresponding code immediately. It would be extremely useful to intuitively create groups while preserving reproducibility.

At first I thought you could only pass strings to JS objects through htmlwidgets which I thought would be a limitation for the data exchange required between R and JS (points positions). But then I found out about JS()
I think I'll start working towards that. I'll first improve my knowledge in highcharts/htmlwidgets, and then see how this could be done.

Will keep you updated on this issue if I do any progress :)

Ok @SelimRABOUDI 😉

Luck with that! I'll close the issue. If I have some news I'll talk to you here.
