PROCEDURE: contour2d,data PURPOSE: Produces contour plots of pitch angle dist.s from 2D data structures. INPUTS: data - structure containing 2d data (obtained from get_fa_???() routine) e.g. "get_fa_ees, get_fa_ies, etc." KEYWORDS: LIMITS - A structure containing limits and display options. see: "options", "xlim" and "ylim", to change limits UNITS - convert to given data units before plotting MSEC - Subtitle will include milliseconds TITLE - Title to be plotted, - set title=' ' for NO Title! - set title='1' for just the time in the title XTITLE - xtitle to be plotted, - set xtitle=' ' for NO xtitle!, default determined by VEL keyword YTITLE - ytitle to be plotted, - set ytitle=' ' for NO ytitle!, default=data.units_name ZTITLE - ztitle to be plotted, - set ztitle=' ' for NO ytitle!, default='Log!D10!N('+y_units+')' RETRACE - set to number of retrace steps removed, - typically set to 1 for FAST esas - minus number will remove -(retrace) steps from end of sweep VEL - If set, x-axis is velocity km/s -- Default is Energy (eV) NCONT - Number of contours to be plotted, default = 8 LEVELS - Explicit contour levels, default levels spaced down from max by 10^.5 FILL - If set, contours are filled with solid color or gray scale BW - If set, contours are white, no affect on fill plots PURE - If set, 6 pure colors are cycled through for levels POLAR - Makes a polar plot ROTATE - Exchanges x and y axes for non-polar plots LABEL - Labels the contour levels LAB_0 - Puts 0 in center of plot (default is 90). Labels pitch angles with 90 degree increments. LAB_90 - Puts 90 in center of plot (default is 90). Labels pitch angles with 90 degree increments. LAB_180 - Puts 180 in center of plot (default is 90). Labels pitch angles with 90 degree increments. XMARGIN - Change xmargin from default YMARGIN - Change ymargin from default See "pitch2d" for another means of plotting data. See "conv_units" to change units. CREATED BY: J. McFadden 96-8-31 FILE: contour2d.pro VERSION 1.
