Chapter 2QuickplotsThis chapter presents quickplots that are collections of <strong>DISLIN</strong> routines to display data with one command.The following rules are applied to quickplots:- Quickplots call DISINI automatically if it is not called before. METAFL (’XWIN’) will be usedin quickplots if METAFL is not used before.- On window terminals, there are no calls to ENDGRF and DISFIN in quickplots, they let <strong>DISLIN</strong>in level 2 or 3. If the variable ERASE is set to 0, following quickplots will overwrite the graphicswindow without erasing the window.2.1 The PLOT FunctionThe function ’plot’ makes a quickplot of two floatingpoint arrays.The call is:xray, yrayplot (xray, yray)are floatingpoint arrays.Example: from math import *from dislin import *x = range (100)y = range (100)for i in range (0, 100) :v = y[i] / 5.y[i] = sin (v)plot (x, y)2.2 The SCATTR FunctionThe function ’scattr’ makes a quickplot of two floatingpoint arrays where the points are marked withsymbols.The call is:xray, yrayscattr (xray, yray)are floatingpoint arrays.5
