Plotting software

Figure 4 is a set of contour plots of data derived from three Standard Pole Figure scans on a highly oriented specimen of linear polyethylene. The contour plotting software establishes a set of intensity levels that span the data in the diffraction data file. 

Equations (5.73) and (5.74) are based on Equation (5.68). In the middle of the cell, the temperature is the cell temperature (Tc) calculated from the steady state model. The 2-D temperature distribution thus obtained is as shown in Figure 5.30. Though only three temperatures are calculated along x -direction for each layer the interpolation done by the plotting software gave detailed contours that show the distinction... 

It is useful to provide a direct comparison of the three options. To do this, the results from the three file can be stored and plotted using any plotting software. To save the... 

The IC50 was calculated from plots of residual enzyme activity against inhibitor concentration, using Origin Scientific plotting software (Northampton, MA, USA). 

The information in Table 3.1 is presented in a form suitable for direct entry into the graph plotting software in the Kinetics Toolkit. Often with such data, it is more usual to present it so that powers of ten are incorporated into the column headings. So, for example, the column of data for [C10 ] would have numbers running from 3.230 to 0.863. In this case, what form would the column heading take ... 

Thus a label for a column heading in a table could be KiT. (In this case, the numbers that appear in the corresponding column of data are in a form suitable for clirea entry into the graph-plotting software in the Kinetics Toolkit.) However, it is more conventional to include the power of ten in the label. If we return to the previous equation and multiply both sides by 10, then... 

Table 6.1 summarizes the data for the plots in both Figures 6.1 and 6.3. Columns of data for JT (for direct input into the graph-plotting software of the Kinetics Toolkit) and 10 KJT (for the Arrhenius plot) are both given.

These equations can be plotted by a standard data plotting software such as Excel, KG, or Sigmaplot, but first the units and typical values must be checked by hand to insure no errors are made while writing the equation to the spreadsheet. 

The plotting capability in Aspen Dynamics is fairly limited, so it is often convenient to copy all the dynamic information shown in the strip-chart plots and use a more flexible plotting software. For example, the data from Aspen Dynamics can be loaded into Matlab and multiple plots can be generated in whatever form you want. To get a file of the data in Aspen Dynamics, right click the plot and select Show as History. A window opens that contains a table of all the variables, including time in the first column, which can be copied. Many examples of these kinds of plots are presented in subsequent chapters. 

It is expected that numbers, symbols, and unit abbreviations will be used in the written report. Learn to use the symbols and the equation editor in your word processor, and learn to insert symbols, superscripts, and subscripts in plotting software. For example, use 5°C, not five degrees C. Write 25 million/yr instead of 25 million dollars per year. Include lead zeroes in all numbers less than 1, e.g., 0.25 instead of. 25. Use 10 m instead of 10 in both the report and on figures. Items like m/ 3 are considered unacceptable for reports in this Department. 

Derive the streamfunction for the pressure given in Equation 5-107. Write a computer program to calculate pressures and streamfunctions for general (x,y). Integrate the output of this program with commercial contour plotting software to produce capabilities useful in enharrced oil recovery.
