    Question Can you set Column Chart Colors depending upon value

    Can you set Column Chart Colors depending upon value


    Is it possible to change the columns color depending upon the value (e.g. if less than 0 then set column color to red)?

    Thanks in advance.

    So far as far as i can tell no it's not possible. The charting is a third party component and the API is here:

    http://developer.yahoo.com/yui/charts/

    There are however other options for charting

    open flash charts 2 http://teethgrinder.co.uk/open-flash-chart-2/

    flot http://code.google.com/p/flot/
    and ext variety
    http://code.google.com/p/extflot/

    Hope all this helps.

    SOLVED: You can set chart column color depending on the value


    Assuming Ext JS 4.x:

    Code:
    series: [{
        type: 'column',
        ...
        yField: 'yField',
        renderer: function(sprite, record, attr, index, store) {
            var value = record.get('yField');
            var color;
            if (value < 70) {
                color = 'rgb(255, 0, 0)';
            } else {
                color = 'rgb(0, 0, 255)';
            }
            return Ext.apply(attr, {
                fill: color
            });
        }
    }]
