Django and Open-flash-charts (See related posts)

// Found this on the django-users mailing list, need to test

ok, I finally got open-flash-chart to work.

1. create an xhtml-file and insert (something like) this:

    <object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"
        codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/
flash/swflash.cab#version=8,0,0,0"
        width="600"
        height="400"
        id="graph-2"
        align="middle">
    <param name="allowScriptAccess" value="sameDomain" />
    <param name="movie" value="/media/site/chart/open-flash-chart.swf?
width=600&height=400&data=/chart_data/" />
    <param name="quality" value="high" />
    <param name="bgcolor" value="#FFFFFF" />
    <embed src="/media/site/chart/open-flash-chart.swf?
width=600&height=400&data=/chart_data/"
        quality="high"
        bgcolor="#FFFFFF"
        width="600"
        height="400"
        name="open-flash-chart"
        align="middle"
        allowScriptAccess="sameDomain"
        type="application/x-shockwave-flash"
        pluginspage="http://www.macromedia.com/go/getflashplayer"; />
    </object>

2. define the url for the chart, eg: (r'^chart/$',
'www.views.charts.chart'),

3. define the url for the chart-data, e.g.: (r'^chart_data/$',
'www.views.charts.chart_data'),

4. the views:

def chart(request):

   ### nothing really required. whatever you want to do here. points
to the html-file created above

    return render_to_response('site/charts/chart.html', {
        'var': 'var',
    }, context_instance=RequestContext(request) )


def chart_data(request):

    import random

    g = graph()

    data_1 = []
    data_2 = []
    data_3 = []
    for i in range(12):
      data_1.append( random.randint(14,19) )
      data_2.append( random.randint(8,13) )
      data_3.append( random.randint(1,7) )

    g.title('PageViews (2007)', '{color: #999999; font-size: 16; text-
align: center}' );
    g.bg_colour = '#ffffff'

    # we add 3 sets of data:
    g.set_data( data_1 )
    g.set_data( data_2 )
    g.set_data( data_3 )

    # we add the 3 line types and key labels
    g.line_dot( 3, 5, '#333333', 'Page views', 10 )
    g.line_dot( 3, 5, '#666666', 'Visits', 10)    # <-- 3px thick +
dots
    g.line_hollow( 2, 4, '#999999', 'Unique visitors', 10 )


g.set_x_labels( 
'Jänner,Februar,März,April,Mai,Juni,Juli,August,September,Oktober,November,Dezember'.split(',')
 )
    g.set_x_label_style( 11, '0x666666', 2, 1)

    g.set_y_max(20)
    g.y_label_steps(4)
    g.set_y_label_style( 10, '0x666666')

    return HttpResponse(g.render())
