I made some more changes.
OK. There are still a few tab characters
(found some in
libraries/tbl_select.lib.php).

Yes but in your proposal you wrote that you
preferred
jQuery-SVG so I
assume you'll try this one first?
I'll try SVG first. I'm following what others
have to
say about
SVG, Madhura is using it for his GIS
visualization. Tyron
proposed real-time charting but I
don't think
it'll be of much
help in our case.
Hi Ammar,
I'm not sure what exactly your requirement is. But
pls have a
look
at the visualization of data at [1] by
clicking on
the 'Visualize
GIS data' link in the 'Query results
operations'
section towards the
bottom of the page. Try out zooming by double
clicking and panning
by dragging. I believe you are looking for
something
like this for
your zoom search feature.
Madhura,
I have issues operating panning and zooming. Here is the
scenario:
1. Browse world_cities and click Visualize GIS data
2. Click-drag: pans OK
3. Double-click: this is a zoom out, I guess
4. Click-drag: no panning
5. Click "zoom out": data points are enlarging, isn't this a
zoom-in?
Marc,
This is a Firefox compatibility problem. Resolved and pushed to
the repo. Demo will take some time to upgrade to the new
version. Meanwhile if you have Chrome, you can still experience
what it's suppose to do.

Hi,
I was looking up jQuery-SVG and SVG past two days. There has been a
discussion going on in the list about whether to include a different
plotting library than existing(pChart). For now, instead of
including another plotting library, I've developed a prototype that
creates the plot using just SVG. I'll push it to my repo sometime
later today.
Hi,
I've pushed my work. The basic plot functionality is implemented along
with classes for the same. Currently it works only for numeric fields,
I'll add support for other data types after some testing. You can try
scenarios in 'sakila' database and search 'films' or 'film_actor'
table.
Ammar,
I'm concentrating on testing the interface right now, haven't looked at
the code yet.
1. Let's say I choose film_actor, activate actor_id and film_id and
enter 1 as the actor id. When I get the results, I no longer see the
value I entered in the dialog.
But this scenario gives me a notice:
Notice in ./libraries/svg_plot/pma_scatter_plot.php#224
Undefined index:
Backtrace
./libraries/svg_plot/pma_scatter_plot.php#161:
PMA_Scatter_Plot->_prepareDataSet(
array,
integer 0,
array,
string ,
)
./libraries/svg_plot/pma_scatter_plot.php#176: PMA_Scatter_Plot->_svg()
./libraries/tbl_select.lib.php#373: PMA_Scatter_Plot->asSVG()
./tbl_zoom_select.php#131: PMA_SVG_scatter_plot(
array,
array,
)
2. What should I enter as data label to have meaningful results? Please
give an example.
3. Did you find a table (in sakila) for which choosing two columns and
generating a plot would make me recognize some kind of trend in the data?
As an example, on a copy of the film table I did
update film_copy set length = length*3 where film_id > 500
and I was able to see some trend in the plot.
