Charting and Printing

You can chart any of input conditions (Case number, Temperature Pressure/Volume, initial mole of each compound) and output results (mole or activity of each compound) by Graph menu, and print the chart to printer. See Quick Start for how to select the compound and draw the line.

****** Important Caution ******

  1. Although you can select horizontal caption out of any items in combo box, the true horizontal axis is always Cases. The caption is merely made by the item name and its values of initial/final cases. So the user is fully accountable for its reasonability of his selection.
  2. The lines between the case points are simply drawn to join them for visuality, and not reflect actual calculation on those intermidiate points. So you should not regard them as representing actual state at all, especially the section includes a boundary of the existence of a compound.
  3. Since program will adapt the whole size of graph to the form size or paper size, and X-Axis and A-Axis have different origins, apparent aspects of the curves (Results vs Activities) may vary when the form is resized or printed.

In the graph, left side vertical scale is linear scale for mol values of Cases and Results, right side vertical scale is log scale for activity values of Activities. You can read either value by cursor indicator which appears if you check the checkbox located right below of Graphform. There are two combo boxes called Xscale and Ascale to adjust scale for them. In Xscale, you can specify the number of pixels used to display 1 mol in height. Similarly in Ascale, the number of pixels used to display 1 (logA) can be specified.
The chart is drawn by metafile, saved as *.wmf file and print as metafile.

You can customize the appearance of the graph by 'Appearance' button which shows Appearance form (Fig 7).

Line Width for Axis These 5 parameters can be set for display and for printers independently. Since printers have much more dots than display, these independent tunings are practical.

Scale Factor for Save File Windows Metafile(*.wmf) itself is scalable in nature. It has, however, the properties of height/width as boundary rectangle. This factor will control the size of it. If you select '2' , then the height property of the Metafile is twice as the height of displayed image (dots).
