Ah right - that makes sense. Thanks again ;-) On Saturday, 24 May 2014 03:55:39 UTC+1, Andrew W wrote: good work. data just refers to the dictionary.

Hi Andrew,
The URL line now says:
d3.json({{=URL('default', 'dashboard_data.json', scheme=True, host=True)}}
, function (data) {
This doesn't make the information come back though. Does it matter that I
am using pythonanywhere - it looks like they have https:// in place?
Thanks!!

Hi Andrew,
The JSON output is attached (I just grabbed the first 250 lines of some
public data).
My controller code:
def dashboard_data():
dashboard_data = db().select(db.com_house_stock.CompanyNumber,
db.com_house_stock.IncorporationDate, db.com_house_stock.CompanyCategory,
orderby=db.com_house_stock.CompanyNumber)
return dict(dashboard_data=dashboard_data)
def visualisation():
return dict(message=T('Test dashboard'))
And just in case, the visualisation.html code (at the moment I am just
trying to make the code show a table, with just one column of data, get
this to work before I move onto anything more complicated!):
{{
response.files.append(URL('static','js/d3.js'))
response.files.append(URL('static','js/crossfilter.js'))
response.files.append(URL('static','js/dc.js'))
}}
{{extend 'layout.html'}}

var dtgFormat = d3.time.format(%d/%m/%Y);
data.forEach(function (d) {
d.incdate = dtgFormat.parse(d.IncorporationDate);
});
{{# run data through crossfilter}}
var facts = crossfilter(data);
{{# Create dataTable dimension}}
var timeDimension = facts.dimension(function (d) {
return d.incdate;
});
dataTable.width(960).height(800)
.dimension(timeDimension)
.group(function(d) { return Table
})
.size(10)
.columns([
function(d) { return d.incdate; }
])
.sortBy(function(d){ return d.incdate; })
.order(d3.ascending);
dc.renderAll ();
});
/script
Thanks for any pointers you can give!!!

Description: Binary data
[web2py] D3.js DC.js Crossfilter.js - table not showing
Hi,
I am trying to follow the example at:
https://leanpub.com/D3-Tips-and-Tricks/read#leanpub-auto-crossfilter-dcjs-and-d3js-for-data-discovery
In db.py I have created a database and put in some data
In my controller I created a query, and created a JSON view for the data
returned (the view is called default/dashboard_data.json)
In a different view, visualisation.html I have written the following code:
{{
response.files.append(URL('static','js/d3.js'))
response.files.append(URL('static','js/crossfilter.js'))
response.files.append(URL('static','js/dc.js'))
}}
{{extend 'layout.html'}}
h1Dashboard/h1
div class='container' style='font: 12px sans-serif;'

thead
tr class='header'
thIncDate/th
/tr
/thead
/table
/div
/div
/div
script
{{# create dc.js chart object link to DIV}}
var dataTable = dc.dataTable(#dc-table-graph);
{{# load data}}

{
{{# format data}}
var dtgFormat = d3.time.format(%d/%m/%Y);
data.forEach(function (d) {
d.incdate = dtgFormat.parse(d.IncorporationDate);
});
{{# run data through crossfilter}}
var facts = crossfilter(data);
{{# Create dataTable dimension}}
var timeDimension = facts.dimension(function (d) {
return d.incdate;
});
dataTable.width(960).height(800)
.dimension(timeDimension)
.group(function(d) { return Table
})
.size(10)
.columns([
function(d) { return d.incdate; }
])
.sortBy(function(d){ return d.incdate; })
.order(d3.ascending);
dc.renderAll ();
});
/script
The table header returns no problem, but there is no data. I think maybe
the problem is with the section which calls the JSON file, I have tried a
number of different phrases, but nothing changes.
Any help pointing out where I should be looking would be great!!
Many thanks

don't seem to be able to find the correct method of doing this in the book.
If that's not the problem, then I really have no idea where to begin!
If anyone could help at all, I would really appreciate it.

[web2py] Re: D3.js calling Json in View
Thanks Anthony,
When I manually load the JSON file I do see the correct data. The Network
activity (I am using Chrome) seems to show that it pulled the JSON file
back ok.
But I cannot see an Ajax request?? I do see that the D3.JS returns with a
304 status, NOT MODIFIED. Thanks for your suggestion I guess maybe there
is something wrong with the D3 code...

When you manually go to /yourapp/default/dashboard_data.json, do you get
the JSON you expect? If so, when you load the page in question, if you
watch the network activity in the browser developer tools, do you see an
Ajax request successfully pulling in that JSON? If all that works, then the
problem must be either with the format of the JSON or with your D3 code.

[web2py] Re: Best approach to using the DAL with external data sources that will go into multiple tables?
Hi, I am totally new to programming, but in a bid to improve, I am trying to answer any question I reckon I can add value on..so...!.. I would probably define two tables: *Sources data* This table details each of your 38 sources and gives them an ID, you can give them a name, detail the URL you are using, description, etc. *Time Series data* This tables would have 4 columns, ID (unique ref) reference ID - this links to the previous table Date Amount This way you can put all the data in this table, and minimise any duplicate info. Maybe put an index in place - not too sure how these work - but I think they help speed searching, this might be needed if you have lots of values. Your dashboard can then pull info from the time series data to build the graphs yet pull names, source info from the sources data table. Let me know what you think!
