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'}}
<h1>Open source data dashboard</h1>
<p>Pie chart displaying percentages of each category in the database</p>
<div class='container' style='font: 12px sans-serif;'>
<div class='row'>
<div class='span12'>
<table id='dc-table-graph'>
<thead>
<tr class='header'>
<th>IncDate</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}}
d3.json("{{=URL('default', 'dashboard_data.json')}}", function (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>
Thanks for any pointers you can give!!!
