Currently the axis label fit mode in TKChart is restricted to two lines. It could be distracting to the user if the axis occupies too much space. That is why I would suggest adjusting the majorTickInterval property. Another option would be to change the zoom level and enable the pan functionality by setting the zoom and allowPan properties of TKChartAxis. If this doesn't help, please describe in detail your scenario and we will try to find the best solution.
