My application need the ability to display data using a logarithmic X axis.  Kendo doesn't seem to do this but it is available with Flot using a transform option.
              xaxis: {
                    transform: function (v) { return Math.log(v); },
                    inverseTransform: function (v) { return Math.exp(v); }
                },

The transform function supports many other was of reinterpreting the axis so it does much more than just Logarithmic displays.

I love the look of Kendo.  Please consider adding this to your visualization package!
