Plotting program, computer graphics

The plotting program is written on a Tektronix 1+051 graphics micro-computer which is coupled to a 1+662 plotter. 

Describe the color of the reaction mixtures just before loading onto the column. Make observations about the column development process. Analyze the absorbance data by preparing an elution curve. On graph paper or a computer graphics program, plot 520 (j-axis) versus fraction number. How many peaks were obtained What are the components represented by each peak Use this elution curve to explain the action of a gel filtration column. Explain the fact that phenol red is present in both colored fractions. In what fraction is the bovine serum albumin ... 

The proposed functions for the Rhodonines are all plotted to the same reference excitation level. The comers of the ultraviolet spectrum are truncated slightly because of the computer graphics program to implement the... 

In addition to the programs to select the optimum discussed previously, graphic approaches are also available and graphic output is provided by a plotter from computer tapes. The output includes plots of a given response as a function of a single variable (Fig. 11) or as a function of all five variables (Fig. 12). The abscissa for both types is produced in experimental units, rather than physical units, so that it extends from—1.547 to + 1.547 (see Table 5). Use of the experimental units allows the superpositioning of the single plots (see Fig. 11) to obtain the composite plots (see Fig. 12).
