%CO:A,12,70%%C%%H1%%H2%BAR CHARTS FOR THE Z88%H2%%H1%

%C%By Niels Levi
%C%May 1992

%H1%Introduction%H1%

Some time ago, I had to present some results in bar chart form. 
Unfortunately, I was not able to do this on a Z88 and so had to 
humiliate myself and ask a friend, who was very proud of his IBM and 
Harvard Graphics software, to help me.

As a result, I wrote a very simple BASIC program to produce bar 
charts. Using a CLI file, the chart can be transmitted to PipeDream 
so as to add text.  This also means the printer driver can be used to 
alter the printing.

I have not used much energy to make the program user friendly and I 
recommend you edit the program using PipeDream (see Users' Guide 
page 200) to alter the parameters of the bars.


%H1%Method%H1%

LOAD the program into BASIC

Type RUN []+S <ENTER>

Type []-S when the program finishes.  A file (:ram.-/S.sgn) has been 
created which can be loaded into PipeDream for editing. {Remember to 
delete this file once you have loaded it into PipeDream!}


%H1%Changing the Bar Chart Parameters%H1%

The %H2%number%H2% of bars is set in line 20 (I).
The %H2%height%H2% of the bars is set the DATA statement in line 180.
The %H2%width%H2% of the bars is set in line 60 (A).


%H1%Changing the overall size%H1%

This depends upon your printer but, for example, on a Star LC10 the 
size can be reduced by either selecting %H4%Elite Condensed%H4% on the 
printer or changing the User Defined Printer Highlight (in PrinterEd) 
to select same (i.e. change it from 27,120,1 {= NLQ} to 27,65,4) and 
then highlight the bar chart in PipeDream with <>PE.


%H1%"Colouring the Bars"%H1%

Delete lines 60, 80 and 95.

Insert line %H2%33 FOR A=1 TO 10%H2%

Change line %H2%35 FOR N=0 TO Y:D(X,N)=3:NEXT N%H2%

Select the PrinterEd and change character 45 (-) to character 219 or 
223 in IBM Character Set #2 and then change the printer to IBM mode.
