    rangeLabels: {
        format: 'dd-MMM',
        visible: true,
        visual: function(e) {
            var rect = new kendo.geometry.Rect(e.rect.origin, [e.rect.size.width, 100]);
            var layout = new kendo.drawing.Layout(rect, {
                orientation: "vertical",
                alignContent: "center"
            });
            var words = e.text.split("-");
            for (var i = 0; i < words.length; i++) {
                layout.append(new kendo.drawing.Text(words[i]));
            }
            layout.reflow();
