spd_ui_draw_object method: getZRange Calculates the zrange of a spectral plot based upon the set of spectral traces in the panel and the z-axis settings Inputs: dataPtrs(array of ptrs to arrays): Array of ptrs to the z-axis data for this panel. zaxisSettings: spd_ui_zaxis_settings object for this panel. Output: range(2 element double): The determined range scaling(long): The scaling mode: 0(linear),1(log10),2logn fail(boolean): 1 on fail, 0 on success fixed(boolean): 1 if fixed range is used, 0 if autorange is used Keywords: forceauto: Forces an auto calculation to identify the full range of the data $LastChangedBy: jimm $ $LastChangedDate: 2014-02-11 10:54:32 -0800 (Tue, 11 Feb 2014) $ $LastChangedRevision: 14326 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/spedas/gui/display/draw_object/spd_ui_draw_object__getzrange.pro $
