For example, to make a polar plot, you would use a command such as: PLOT, /POLAR, R, THETA The first parameter is the radius, and the second is the angle (expressed in radians). The X and Y vector parameters, both of which must be present, are first converted from polar to Cartesian coordinates. It is convenient to use NSUM when there is an extremely large number of data points to plot because it plots fewer points, the graph is less cluttered, and it is quicker. On logarithmic axes a geometric average is performed. If there are m data points, then m/NSUM points are displayed. If NSUM is larger than 1, every group of NSUM points is averaged to produce one plotted point. The presence of this keyword indicates the number of data points to average when plotting. Note that the IEEE floating-point value NaN is also treated as missing data. If this keyword is present, data values less than the value of MIN_VALUE are treated as missing and are not plotted. If this keyword is present, data values greater than the value of MAX_VALUE are treated as missing and are not plotted. Note: The X and Y axes will be scaled isotropically and then fit within the rectangle defined by the POSITION keyword one of the axes may be shortened. Set this keyword to force the scaling of the X and Y axes to be equal. Changing the value of a system-variable field changes the default for that particular parameter and remains in effect until explicitly changed. When specifying a keyword parameter name and value in a call that value affects only the current call, the corresponding system-variable field is not changed. Note: Many of the graphic keyword parameters correspond directly to fields in the system variables !P, !X, !Y, or !Z. This argument is converted to double-precision floating-point before plotting. Plots created with PLOT are limited to the range and precision of double-precision floating-point values. This argument is converted to double precision floating-point before plotting. If both arguments are provided, Y is plotted as a function of X. If X is not specified, Y is plotted as a function of point number (starting at zero). Graphics Keywords: ] Ī vector representing the abscissa values to be plotted. PLOT can also be used to create polar plots by setting the POLAR keyword. To plot one vector as a function of another, use two parameters. If one parameter is used, the vector parameter is plotted on the ordinate versus the point number on the abscissa. The PLOT procedure draws graphs of vector arguments. If the point is not on the selected base line, the projection point is calculated.Note: Please see the newer PLOT function, which replicates the functionality of this older routine but offers an interactive interface and updated functionality. If your actual starting point is different to the indicated P1, you can use the Abscissa P1 icon to select this point in the drawing. If your measurement did not start with the abscissa 0.00 you can type a new value. The delta is added again.ĭistance that has been measured in the field.Ĭalculated distance of the base line points P1-P2 read-only.Įnter a Measured distance to calculate a factor, which is used to adjust the differences between calculated and measured distance proportional to the abscissa values.Ībscissa value at point 1 default is 0.00. The new value is calculated by adding the delta to the current value. This is useful if you want to calculate a number of points with the same abscissa or ordinate distances. You can specify the values by an absolute number or by delta values, related to the current value. Use the Graphic icon in the abscissa or ordinate row to specify the value in the drawing. Use the Graphic icon in the Constructed row to transfer the values of an existing point into the dialog box. Type negative ordinates to determine points that are left to the base line. Type the abscissa and ordinate of the new point. This is useful, if you want to calculate another point with delta values. Use the Graphic icon to determine the abscissa and ordinate of an existing point. You can edit the coordinates in the dialog box or use the Graphic icon to select another point. If you click a base line in the drawing, the coordinates of the next two vertices are inserted in the dialog box. With a point Offset value you can specify a base line that is tangent to a circle with that radius. P1 and P2: You can specify the base line by two points and a radius (straight lines radius = 0). Type an Azimuth value or use the Graphic icon to modify the orientation of the base line. Type a Radius value, if your base line is an arc. Type an Offset value or use the Graphic icon to shift the line. Click the Highlight icon to show the element in the drawing.Ĭlick Graphic icon to identify another base line.
