Just committed to the SVN: - *New: *XTICKFORMATNUMBER_CB and YTICKFORMATNUMBER_CB callbacks for *IupPlot*.
They are called right before the tick number is drawn, so it can be used to change its format, or change the displayed value. Best, Scuri *XTICKFORMATNUMBER_CB*: allows to modify the displayed string of a tick number in the X axis. If the callback is not defined the internal function is used. (since 3.28) int function(Ihandle **ih*, char* *buffer*, char* *format*, double *x*, char* *decimal_symbol*); [in C]*ih*:xtickformatnumber_cb(*format*: string*, x*: number, *decimal_symbol*: string) -> (*ret*: number, *buffer*: string) [in Lua] *ih*: identifier of the element that activated the event. *buffer*: buffer that will receive the string with the formatted number. In Lua the string is returned by the callback, then copied to the buffer. The buffer is limited to 128 characters. *format*: the format string used by the internal function to format the number. *x*: X coordinate value of the tick number. *decimal_symbol*: the decimal symbol used by the internal function. Returns: If IUP_IGNORE the number is not plotted. If IUP_CONTINUE the internal function is used.
