X axis format for the tick values in the second X axis. It could be a string with the sprintf format or an array where the first parameter is the sprintf format and the second parameter is a modification applied to the value before is passed to the sprintf function, i.e. ("/1000", "+ 100", etc.)
Font size for the text in axis text. Be aware that auto scaling font must be turned off for this property to take effect. A more convenient way to modify the size is to use the xAxisTextScaleFontFactor
