- QUICKGRAPH - A PROGRAM TO DEVELOP GRAPHS QUICKLY FOR BUSINESS
- PRESENTATIONS USING THE "GRAFTRAX" PRINTING FEATURE ON THE EPSON
- OR OTHER DOT-MATRIX PRINTER
-
- Summary - this program produces four types of graphs, simple
- bargraphs, stacked bargraphs, scatter graphs, and linegraphs.
-
- The graphs are first produced on the screen, and then are printed
- on paper using the GRAFTRAX commands
-
- Left Shift + PrtSc = Small graph
- Right Shift + PrtSc = Large graph
-
- Setting up -
-
- Be sure you have a color graphics adapter installed - this
- program will not work on the IBM Monochrome adapter.
-
- When you boot the system, if you plan to print the graphs on
- paper, be sure you have included GRAFTRAX in your AUTOEXEC.BAT
- file.
-
- That's it! there is nothing else to do except run the program
- from the DOS command level using the simple command:
-
- A> QUIKGRAF
-
- Technical Discussion (if you want to read on)
-
- This program is written in advanced basic and produces graphs on
- the Green screen or color monitor screen in either high resolution,
- (200 x 640) or low resolution (200 x 320) graphics. The high
- resolution graphics are always in black and white, and produce
- only those colors (no grays) when the graphs are printed on the
- dot matrix printer. The advantages of high resolution are that
- more words are available per unit space, the disadvantages are
- that it is difficult to distinguish between more than two
- variables where this is important. The low (IBM calls it medium)
- resolution graphics produces full color graphs on the screen for
- those of you that have color monitors, and shades of gray, black
- and white for those of you that are using a monochrome monitor
- with the color graphics card. When the low resolution graphs are
- printed on paper, the colors or gray shades print out as black,
- grays, and white.
-
- When you are plotting line graphs or scatter (Unconnected points)
- graphs, there is no color or shades of gray, instead the program
- plots different symbols for each variable, so high or low
- graphics works equally well.
-
- There is no need to worry about the scale for either the
- horizontal (x-axis) or the vertical (Y-axis) as the program
- automatically sets these based on the data entered. Either
- positive or negative numbers from -9999 to +9999 can be entered
- for any of the variables and the program will set the scale
-
-

-
-
- factors to provide the best presentation. Specifically, if all
- variables are positive, the scale goes (on the vertical or y
- axis) from zero to 115% of the largest number entered. If there
- are some negative numbers, it goes from 115% of the largest
- negative number to 115% of the largest positive number. NOTE:
- negative numbers do not work well on stacked bargraphs (obvious).
- The width of the bars (for the bargraphs and stacked bargraphs)
- are set by the program to match the number of variables and the
- number of time steps you have chosen. The range for the
- horizontal axis for the line graph goes from the smallest number
- to the largest number. For the scatter graph, the program adds a
- little space on both ends of the scale so that the points are
- more easily observed.
-
- NOTE: ALL THIS IS DONE FOR YOU, ALL YOU HAVE TO DO IS ENTER THE
- DATA!
-
- Operating instructions -
-
- The data is entered in 5 easy steps:
-
- 1. Define the resolution (High or Low)
- 2. Define the type of graph
- 3. Define how many variables and time steps
-
- (at this time a blank data sheet will appear on the screen)
-
- 4. Put names on the variables and time steps, and then
- enter the data (numbers) in the proper location on the data sheet.
- During this step, if you make a mistake continue with the rest of
- the data entry, and when you are finished, when you are asked,
- "are all values correct", enter a "N" for NO, and using carriage
- returns, advance the cursor to the right location and overwrite
- the bad data with the correct entry.
-
- (after all data is entered, the filled in data sheet will
- disappear)
-
- 5. Label the horizontal (x-axis), vertical (y-axis) and the
- graph title itself.
-
- Any error in data entry can be corrected using the backspace key
- located to the left of the NumLock key.
-
- If you make a mistake in the selection of the first three steps,
- (i.e. the resolution, graph type, or number of variables) you
- must start over.
-
- Printing the graph -
-
- After all data is entered, a warning will be flashed on the
- screen, prompting you to "Hit any key to continue".
-
- This will activate the graph on the screen. Once it is on the
- screen, then you have two choices - print the graph using the
-
-
- 2
-
-
-
- GRAFTRAX commands, or push the ESCAPE key to clear the screen.
