-
- Included in this archive:
-
- PPlot (Main program )
- PPlot.doc (This doc file )
- PPlot.Support (Required Support file)
- PPlot.Importing (Another doc file )
- PPtest (A demo data file )
- PPtestIFF (A demo IFF pic )
- .info files (Icons )
-
- System Requirements:
-
- The program has been tested on A500s under 1.3 and 2.04. The program
- runs best under 1meg of CHIP, but it can be coaxed into running under
- 512K of chip. I *do* recommend at least 1 meg of ram, though. PPlot
- is very CHIP-ram intensive, so I recommend at least one meg of memory
- total.
-
- The program has not been tested on the A3000 yet, so I'm not sure how
- well it likes/dislikes the 030. If you have problems, please E-Mail.
-
- Setting up:
-
- First, make a directory for PPlot and copy all files into it. You
- *need* only the PPlot and PPlot.Support files in this directory, but
- you may want to keep the docs around. And there you have it ... PPlot
- is installed.
-
- Using PPlot's menus:
-
- PPlot has three main menus, the DATA MENU, the PLOT MENU, and the
- SETTINGS MENU. The program starts you off in the DATA MENU, where
- most of the data entry/editing functions are. The PLOT MENU has
- many options for determining the plot's appearance. The SETTINGS
- MENU has switches for options that can be toggled.
-
- DATA MENU
-
- New Data : Enter a new set of data into PPlot. Maximum 500 points.
- Load : Load an old set of data.
- Save : Save a set of data.
- Quit : Obvious. Really. :)
- Plot Menu : Go to PLOT MENU. You must have data in memory first.
- Display : Display your data on the screen. If you have more than
- 15 points and get a "more" prompt, just type <Return> to
- keep going, '0' to go to the beginning, and '1' to go to
- the end.
- Print : Prints your data set and the best line to the printer.
- Edit Pair : Change the contents of a point and/or the error of a point.
- You need the point number of the point you wish to change,
- obtainable with the "Display" or "Print" commands.
- Add Pair : Add another pair to your data set.
- Del Pair : Delete a pair from your data set. Requires the point
- number. Asks for confirmation forst, don't worry!
- Swap X&Y : Swaps the X and Y coordinates of all the pairs. Also
- the error values.
- X-Error : An easy way to set the error in X on *all* your points.
- Y-Error : An easy way to set the error in Y on *all* your points.
- Sort : A "switch" to turn on/select the type of sort that will
- be performed on the data points. Useful with the
- Interpolate curve fit.
-
- PLOT MENU
-
- X-Bounds : Lets you enter X boundaries for your graph.
- Y-Bounds : Lets you enter Y boundaries for your graph.
- Grid/Ticks : Selects the interval at which to draw tick marks or
- grid lines.
- Labels : Title, X-axis and Y-axis labels.
- Plot Data : Plots your data using the current settings.
- LSQ Fit : Displays the equation of the Least-Squares best line.
- X-Transfrm : Lets you perform several mathematical functions on
- your data (and their associated errors). From the
- TRANSFORM MENU, select the function to apply. If
- there is a 'c' in the function, you wil be prompted
- for its value.
- Y-Transfrm : Same as X-Transform, except for Y. :)
- Settings : Takes you to the SETTINGS MENU
- Autoscale : Sets the graph's borders and the grid/ticks to
- something easy to display. Use if you don't know where
- your points will fall. Also a guide to help you set
- bounds to get a nice looking graph
- Data Menu : Takes you back to the DATA MENU
- Plot Which : Lets you select a "range" of points to plot, e.g. from
- point 15 to point 35.
-
- SETTINGS MENU
- Plot Menu : Guess. :)
- Origin : If possible, draw a solid set of "axes" at 0,0.
- X-Bars : Draw error bars in the X direction.
- Y-Bars : Draw error bars in the Y direction.
- Line : Draw the Least-Squares best line on the plot.
- Eq'n : Print the equation of the Least-Squares line on the graph.
- Color : Number of colors on the plot. NOTE: Only the two-color
- plot is saveable to an IFF file. The four-color plot is
- simply so you can look at the plot w/o being blinded by the
- flicker.
- Res : Selects the resolution of the plot (Interlace or not).
- Points : Selects the method of "marking" the location of the
- data points, e.g. putting an X at the location of the
- point.
- Interp : Selects whether to "Interpolate" the points. This just
- does a connect-the-dots between the points. Can look
- weird if the data isn't sorted. :)
- Grid/Ticks : Selects whether to draw a grid or tick marks on the axes of
- the graph.
-
- Using The Plot:
-
- You have several options in the plot menu, most of them mapped to keys.
-
- "A" - Autoscales the plot without changing the grid intervals.
- "O" - Sets the bounds back to what they were when you selected
- "Plot Data".
- "X" - Toggles X-Error bars.
- "Y" - Toggles Y-Error bars.
- "G" - Toggles the grid/ticks.
- "4" or "6" - Sorts data in the X direction. Useful with Interpolate.
- "8" or "2" - Sorts data in the Y direction. Useful with Interpolate.
- (NOTE: Look at the sides of the numeric keys. :) )
- "S" - Save the graph as an IFF file. NOTE: Works *only* in
- Two-Color mode!
- <Return> - Goes back to the PLOT MENU
-
- Also, you can click twice in the graph area with the mouse to zoom in on the
- rectangle inside where you clicked. Sorry, no drag-select, but it's *still*
- useful. :)
-
- Usage Notes:
-
- Any time you have a block cursor, you can use <Del> or < <- > to delete a
- character, or hit <Esc> to erase the entire input line.
-
- To enter lots of points with the same error, enter the data as "exact" then
- use "X-Error" and "Y-Error".
-
- Don't set the automatic sort on when you're using long sets of data.
-
- There is a "Quit" in the menu bar. This quits *instantly* from any mode or
- any operation!
-
- See the file "PPlot.Importing" for information on how to enter the data with
- a spreadsheet or another program.
-
- Other Information:
-
- PPlot was developed using AC/BASIC which is (C) AbSoft. A 'C' version is
- planned for sometime in the near future, when we can get around to it. :)
- (A Chem E student's life is a busy one... :) )
-
- PPlot is FreEWare, which means it costs you *nothing*, but I'd like to hear
- from you if you have access to E-Mail and use it. :) Questions, comments,
- bug reports, whatever. I like E-Mail. :) PPlot is also freely distributable
- provided all files (except the demo pic/file) remain intact.
-
- If Fred Fish wants to put this on a disk, he can. (Not likely, but ... :) )
