Name: GRAF 6 GRAF plots a two-dimensional axis system. level 1 The call is: CALL GRAF (XA, XE, XOR, XSTEP, YA, YE, YOR, YSTEP) or: void graf (float xa, float xe, float xor, float x- step, float ya, float ye, float yor, float ystep); XA, XE are the lower and upper limits of the X-axis. XOR, XSTEP are the first X-axis label and the step between labels. YA, YE are the lower and upper limits of the Y-axis. YOR, YSTEP are the first Y-axis label and the step between labels. Notes: - GRAF must be called in level 1 and automatically sets the level to 2. When plotting more than 1 axis system on a page, ENDGRF must be called in between each new set of axes in order to set the level back to 1. - The axis scaling is linear by default and can be changed with AXSSCL. For logarithmic scaling, the corresponding parameters in GRAF must be exponents of base 10. - If the numerical value of the lower limit of an axis is larger than the upper limit and the label step is negative, axis scaling will be in descen- ding order. Name: GRAFP 6 The routine GRAFP plots a two-dimensional polar axis system. The call is: CALL GRAFP (XE, XOR, XSTEP, YOR, YSTEP) level 1 or: void grafp (float xe, float xor, float xstep, float yor, float ystep); XE is upper limit of the X-axis (radius coordinate). XOR, XSTEP are the first X-axis label and the step between labels. YOR, YSTEP are the first Y-axis label and the step between labels specified in degrees. The Y-axis is scaled from 0 to 360 degrees. Notes: - The direction and position of the angle labels can be modified with the routine POLMOD. - GRAFP is a new name for the old routine POLAR, since polar is also a C99 function. The old rou- tine POLAR is still in the DISLIN libraries. Name: ENDGRF 2,6 The routine ENDGRF terminates an axis system and sets the level to 1. This routine must be called when plotting more than 1 axis system on a page. The call is: CALL ENDGRF level 2, 3 or: void endgrf (); Note: ENDGRF contains a call of the routine SENDBF that can be disabled with the routine BUFMOD.

Name: BOX2D 6 The routine BOX2D plots a border around an axis system (or around the rectangle defined by AXSPOS and AXSLEN). The call is: CALL BOX2D level 1, 2, 3 or: void box2d (); Name: TITLE 6 TITLE plots a title over an axis system. The title may contain up to four lines of text designated with TITLIN. The call is: CALL TITLE level 2, 3 or: void title (); Name: ADDLAB 6 Additional single labels can be plotted on an axis system with the routine ADDLAB. The call is: CALL ADDLAB (CSTR, V, ITIC, CAX) level 2, 3 or: void addlab (const char *cstr, float v, int itic, const char *cax); CSTR is a character string containing a label. V is a user coordinate that defines the axis posi- tion of the label. ITIC is an integer option that defines if a tick mark is plotted. ITIC = 0 means that no tick is plot- ted, ITIC = 1 defines a minor tick and ITICK = 2 defines a major tick. CAX is a character string that defines the axis. CAX can have the values 'X', 'Y', 'Z', 'XTOP' and 'YRIGHT'. Name: XAXIS 7 XAXIS plots a linear X-axis. level 1, 2, 3 The call is: CALL XAXIS (A, B, OR, STP, NL, CSTR, IT, NX, NY) or: void xaxis (float a, float b, float or, float stp, int nl, const char *cstr, int it, int nx, int ny); A, B are the lower and upper limits of the axis. OR, STP are the first label and the step between labels. NL is the length of the axis in plot coordinates. CSTR is a character string containing the axis name. IT indicates how ticks, labels and the axis name are plotted. If IT = 0, they are plotted in a clock- wise direction. If IT = 1, they are plotted in an counter-clockwise direction. NX, NY are the plot coordinates of the axis start point. The X-axis will be plotted from left to right. Name: YAXIS 7 YAXIS plots a linear Y axis. level 1, 2, 3 The call is: CALL YAXIS (A, B, OR, STP, NL, CSTR, IT, NX, NY) or: void yaxis (float a, float b, float or, float stp, int nl, const char *cstr, int it, int nx, int ny); A, B are the upper and lower limits of the axis.

Name: GAXPAR 6 The routine GAXPAR calculates parameters for GRAF from a minimum and maximum of data values. The call is: CALL GAXPAR (V1,V2,COPT,CAX,A,B,OR,STEP,NDIG) level 1, 2, 3 or: gaxpar (float v1, float v2, const char *copt, const char *cax, float *a, float *b, float *or, float *step, int *ndig); V1, V2 are the lower and upper limits of the axis. If V1 > V2, the calculated parameters will be in de- scending order. COPT is a character string that can have the values 'NOEXTEND' and 'EXTEND'. For COPT = 'EXTEND', the calculated axis limits are extended to a full axis step. Otherwise, V1 and V2 are used as axis limits. CAX is a character string that defines the axis. CAX can have the values 'X', 'Y', and 'Z'. A, B are the calculated limits of the axis. OR, STP are the first axis label and the step between labels. NDIG is the calculated number of digits after the deci- mal point that should be set with the routine LAB- DIG for the labels. Notes: - The same algorithm as in SETSCL for setting auto- matic axis scaling is applied to GAXPAR. - The current axis settings such as linear or loga- rithmic scaling are used by GAXPAR. For loga- rithmic scaling, the parameters V1 and V2 must be exponents of base 10.
