[A] [ALTER] Command
Subcommands:
Blank [AB] Blank (clear) screen and redisplay frame & grid.
Data and scales in memory are unaffected. (Same as Function 7)
Frame [AFxn] (x = B, T, L, [R], F or S. n =value)
Select size of graph frame. The default (start-up) sizes are:
Bottom:0, Top:6, Left:9 Right:40 or 80 columns.
Once the size has been altered, the frame will be fixed until altered
again. All graphs created will be confined to the current frame size.
Ranges: Bot:0-5, Top:1-6 Left:8-30 or 8-70. Right: 12-40 or 12-80.
AFF: Reset frame to full size. AFS: Display Status values.
e.g.s AFL12<RTN> (Alter Frame Left side to 12).
AFT5 (Alter Frame Top to grid line 5).
AFR72 (Alter Frame Right side to 72).
AFB1 (Alter Frame Bottom to grid line 1).
AFF (Alter Frame to full size: 0,6,9,40 or 80)
AFS Displays: Bot: Top: Left: Right: current values.
Notes: The frame is immediately adjusted on screen whenever AFF
(Full Frame) is selected. Any other frame altering will not affect
the screen until BLANK (Fn 7) is pressed or a new graph is generated.
Up to 9 separate graphs can be displayed in high res.
(4 in low res.) by selecting bot, top, left and right values.
If a frame is reduced in height or width, the scale is automatically
adjusted.
e.g. Two separate graphs (set to low res. for this example):
MB
FLSALES<RTN>
AFR20<RTN>
GS
FLWAGES<RTN>
AFL27<RTN>
AFR40<RTN>
GB4
Heading [AH] (and Draw Text [DTF])
Allows entry of a heading up to 28 characters long in low resolution and
68 in high resolution. The heading can be located anywhere on the screen
by selecting first the row number (2 to 24) then the start column (1 to
34 or 74). The defaults are [C] (automatic centering) on the row below
the top of the current frame.
This heading will remain in memory until changed. It is not saved to disk.
The heading text may be entered at any time. Subsequent AH commands
will use the current heading if <RTN> is entered. Notes: Symbols and
spaces may be used in the heading. An alternative method for adding
text to the screen is the Draw Text [DT] command. If the DRAW program
is loaded, additional text fonts are available. AH command is normally
used for adding single-line text to a graph from a macro.
For text exceeding a single line, create a text file using the Text Editor
[FCT] commmand. This can be called up and placed anywhere on the screen
with the [DTF] command and selecting starting Row and Column positions.
e.g. within a macro: DTF ;textfile; ;14; ;20;
Key [AK] (Same as Fn 8)
This command toggles the bottom line of the display between the Function
keys, the contents (Title) of each of the first four memories, and blank.
The current default drive and file are also shown in column one.
Pan [APn]
Pan allows movement "sideways" through the data in memory 0, so that
a graph may be drawn at any start point. Following the AP command,
you must enter the start-date (as MM/YY) or the X-value<RTN>.
The maximum number of points in a memory is 365.
A short cut to jump to the start of the next page is to enter "N"
(for New page) instead of the date or X-value.
(Notes 1.For quarterly data, enter the date as n/YY where n is 1,2,3,4)
2.For random (Other) data only APN applies.
3.The FILE Edit program has its own Pan facility, to edit data
beyond the first 63 points.
4.Pan does not apply to PIE and BLOCK charts.
Examples: AP4/86<RTN> AP210<RTN> APN<RTN>
Scale [ASx]
Scale allows alteration of either the X or Y scales. The sub-menu is:
Exponential Log. XY-new Y-new
(X scale alteration is only possible when random (other) data is present in
memory 0.)
Exponential [ASE] converts the data in memory 0 to: 10 raised to the power
of each data point. This is the opposite (complement) of Log.
The data in memory 0 to be converted, should be within the range 1 to 10.
Log. [ASLx] (Where x= Actual or Log values)
Converts the data in memory 0 to base-10 logarithm. The displayed values on
the Y axis may be actual or log values. If log is chosen, the scale on the Y
axis will then represent powers of 10. This is the oppposite of Exponential.
Avoid using the ASL command when the data file has zero, negative or very
small data values (such as .01).
XY-new [ASX] resets the previously set automatic scales for both the X
and Y axis. (Same as [MN] command.)
The data in memory 0 is not changed.
You will normally use this whenever the data in memory 0 is changed and
the new data values do not match the old scales. (The data in memory 0
changes when new data is loaded from a disk file or another memory, or
the original data has been altered with commands such as ASE or ASL.)
Y-new [ASYn] allows manual adjustment of the Y-axis scale following the
initial automatic scale calculation. After entering the ASY command, you
will be asked:
"Change Y scale: High, Low or [P]ercent" Type in H, L or P
In the case of H or L, follow by the new high or low Y-axis limit,
then <RTN>.The screen may need to be cleared ready for your next Graph
command. The data in memory 0 is not altered.
The scale range available is +- .006 to +-9999997.
Percentage [ASYP] The Y scale is altered to: 0 - 100%. Each data
value is changed to become the % of the total of all data values in the
file. Following ASYP the screen should be cleared and the graph redrawn.
The Y scale may subsequently be altered with [ASYH or L].
Title [ATxx] (x= Location on screen, Title or None)
Title contents: [ATTx]
This is a quick way to replace the last displayed title.
Example: ATTSales85<RTN> ( Note that memory 0 must contain some
data before this command will operate.)
Location: [ATLxn] (x=Row or Column, n= row number)
The graph title(s) may be either displayed in the upper left corner of
the graph (Column mode) or on any row (Row mode). If Row is selected,
you may select the row number (2 to 24).
None: [ATN] Removes current title, sets flag so that subsequent graphs
do not display a title. Title flag reset with ATT or MN.
Ytitle [AYx1x2] (x1=L or T) (x2=L or R, or title)
This is a quick way to replace the currently displayed Units (Y-axis)
title on the left side of the screen or the location of the Y-axis
labels.(Can select Left (default) or Right.)
Ytitle: AYT title<RTN>
Examples: AYT Dollars<RTN> AYT Quantity<RTN>
Location: AYL (L=location). Then enter L (left) or R (right).
Examples: AYLR AYLL
(Notes: When Y-labels are selected for the right side, the frame width
is reduced by 72 pixels. To remove a Y title, enter: AYT<RTN>)
Xtitle [AXx row col] (x=new X title)
This command is used to change the current X-axis title and its screen
location. (Defaults are: Centered on one line below the top of the frame.)
The new location values will remain until changed.
Example: AX Weeks<RTN> 20<RTN> 15<RTN>
Zoom [AZn]
Zoom command allows you to control the number of X-axis data points
actually displayed. The number can be in the range 1 to 70.
Example 1: Load a data file: FLSALES<RTN> then AZ12<RTN>
(The screen is not cleared.) Now enter the required graph command.
e.g. to Graph a Column chart: MB GC11
Only 12 columns will be displayed, expanded to fill the
available graph space.
Example 2: MN AZ70<RTN> GLL
Notes: Alter Zoom is not applicable to Random (Other) files. Use Alter
Scale X [ASX] to achieve the same result.
Alter Zoom does not apply to PIE and BLOCK charts unless the memory
0 data is transferred to memory 2 [MT2] then back to mem. 0 [ML2].
