Ammar, it works well so far!
Suggestions:
- As the default data label, use the display field if it exists (from
libraries/relation.lib.php, PMA_getDisplayField() )
- For the title, instead of "Scatter Plot", give some indications
(how
to zoom, how to click, etc) or give a link to get such indications
- Is it possible to enlarge the size of the working zone? ideally, to
drag it by one of its corners?
I used the jquery-ui plugin and implemented this.
:) I'll try and look into it.
- You seem to prefetch the whole table and I'm concerned about
response
time and memory issues for big tables (try it with the payment table and no data restriction). When hovering over a dot, maybe fetch the rows one by one with Ajax? Or use Ajax if there are more than a certain number of rows.
I was also very much concerned about this. This happens even with the 'Display chart' functionality in the browse tab. I pre-fetch the table for making the initial plot and store the data row for each point. One solution can be like: Now I'm generating query like 'Select * from table' which I'll change to 'Select x,y from table' and then when hovering or clicking over the plot, I'll fetch the data row.
Your solution of fetching just the needed columns will help, but we'll need another safeguard for big tables. I'm thinking of a configurable maximum of rows to fetch. Think of it, showing millions (or even thousands) of dots won't make any sense.
So like in table browse mode we can generate the plot for 500/250 rows.
Then
if user wants we can replot with the next 500/250. Although I agree it
will
only complicate the plot and its hard to make sense from the plot. Or we can also ask the limit as input but I think the user might find it annoying or unnecessary.
for the 'Display chart' feature I thought of using a zoom feature like this: http://www.highcharts.com/demo/dynamic-master-detail
What if we make 2 sql queries to find out the min and max value of the
'x-axis', then select like 100-200 values that are equally distributed over the x-axis and display those?
Hope that was understandable.
Sampling is okay but only if we use a good sampling technique. There might be the case where we miss what the user is looking for. In partitioning we wont miss but might complicate matters.
- Clicking on a point shows the whole row; is it possible to show a
pencil icon which would permit to bring another panel to edit the
row?
Still thinking about a panning mechanism?
Any possibility of this feature for multi-tables?
