I found it faster and more efficient to generate the DataTable using
google's gviz_api

Re: bar charts

[Mario Gudelj]

Hey, I implemented a line chart and this is my code:

View:

def render_chart(request):
months =
['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec']
month_values = [0,0,0,0,0,0,0,0,0,0,0,0]
list_of_items = MyModel.objects.all()
for item in list_of_items:
if item.creation_date.strftime("%b") ==
months[item.creation_date.month - 1]:
month_values[item.creation_date.month - 1] =
month_values[item.creation_date.month - 1] + 1

d = {'user':request.user, 'months':months, 'month_values':month_values}
return render_to_response('chart.html', d)

And this is the template:

script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Month');
data.addColumn('number', 'bookings');
data.addRows(12);
{% for month in months %}

data.setValue({{forloop.counter0}}, 0, '{{month}}');
{% for value in month_values %}
data.setValue({{forloop.counter0}}, 1, {{value}});
{%endfor%}
{%endfor%}
var chart = new
google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, {width: 760, height: 380, title: 'Stats'});
  }

Re: bar charts

[Brad Montgomery]

+1 for Google Charts.


For small stuff (1 chart), I just render JavaScript in the  of my 
html templates. For more complex stuff, you could write a view that *just* 
renders JavaScript and include it via a script tag. Just make sure to serve 
it with MIME type "application/javascript"


Here's more info on generating Non-HTML content:

You could try out cairoplot, it works for me in Django, just have to print

Pass serialized json as a template variable?

That's what I'm doing atm. But JKM has built an app to help reduce the need
to write javascript [1]. I haven't used it myself, but it looks interesting

Kenneth,

It's a Google API. Like other Google tools, you can connect using
google.load() within JavaScript code. It wouldn't integrate directly with
Django, but rather through your templates by using JavaScript.
