Zoom and moving around with mouse for Gaston plots, in Pluto

[VarLad]

These two basic functionalities are available easily with svg terminal....
Also, svg terminal is clearer than png one for quality so you might wanna consider that for default....

Also, I did try
set(preamble="set terminal svg size 600,400 dynamic enhanced mousing"), while the size parameter worked, the others didnot.
So.... any way I can implement this myself in Gaston?

Please don't ask multiple questions in one issue; it becomes difficult to keep track of them. Also, I'd prefer if you asked support questions in Discourse.

You had already opened an issue about support for SVG interactivity in Pluto here. The situation has not changed.

Don't use the preamble to set terminal options. Rather, use termopts. This is explained in the documentation: https://mbaz.github.io/Gaston.jl/stable/faq/#How-to-set-the-terminal-1

The last issue required a lot of hard work
This one is just
set term svg enhanced dynamic mousing
Easy to implement

Also, in Gaston, with set(term = "svg", termopts="size 600,400 dynamic enhanced mousing")
Doesn't work
Instead I get this

┌ Warning: Gnuplot returned an error message:
│   
│ gnuplot> set term pngcairo size 600,400 dynamic enhanced mousing
│                                         ^
│          line 0: unrecognized terminal option
│ 
└ @ Gaston ~/.julia/packages/Gaston/ctAQy/src/gaston_llplot.jl:182

The closest I got was with preamble...
It works fine in gnuplot

gnuplot> set term svg enhanced dynamic mousing

Terminal type is now 'svg'
Options are 'size 600,480 dynamic enhanced font 'Arial,12' mousing butt dashlength 1.0 '
gnuplot>

The plots produced with
set term svg enhanced dynamic mousing
already have zooming and dragging functionality automatically, when displayed on a website... You can try it yourself or look at the http://gnuplot.sourceforge.net/demo_svg_5.5/simple.html

[VarLad]

Also, this works, only the size parameter though
set(showable="svg", termopts="size 1000,400 dynamic enhanced mousing")

I think its forced on pngcairo on both ijulia and pluto!

@mbaz Is that intentional or a bug?

[VarLad]

@mbaz
Should I open an issue for it?😅

[mbaz]

To enable SVG plotting, you need a Pluto cell with:

begin
    set(term="svg")
    set(showable="svg")
    set(termopts="dynamic enhanced mousing size 800,600")
end

However, as explained in #146, you will not get an interactive plot, because Pluto does not execute the javascript embedded in the SVG.

Tried it in Pluto! Works great and gives the expected output!
I'm asking if you can make Gaston display images "by default" using this?
Any reply on this would help!
Thanks!

[VarLad]

The above displays svg in Pluto, which can be zoomed dragged and the 2d coordinates are there on mouse pointer

[VarLad]

@mbaz Can you confirm if you can implement it by default in Gaston?

[mbaz]

See fonsp/Pluto.jl#546

Support for raw SVG output embedded in an HTML page will be present in v1.1.0.

[VarLad]

Thanks😁

This is working on my private development branch. Not available yet, but I wanted to let you know. This branch will become v1.1.0 in (I hope) a couple of weeks.
