2.Anybody have a way to set a single grid line on? a horizontal baseline in mid-graph?

Susan the java api commands that you need are

To stop the frame displaying.

setFrameDisplay(false);

I'm assuming you mean showing the zero line when a graph has both +ve and -ve values the following remove standard axis lines.

setY1AxisLineDisplay(false);
setX1AxisLineDisplay(false);
setO1AxisLineDisplay(false);

The following displays the zero line and sets it's width.

setY1ZeroLineDisplay(true);
setLineWidth(getY1ZeroLine(),.5);

thanks jack, actually its the 1 line.
Is ZeroLine a special sitch?
Can you tell me how to turn on a line at a specific value?
and how to fix the y axis range?
i am making 50 graphs and i want them all to have the same yaxis -1 to 3.

I'll go turn my frame off right now. thanks.

Susan, The best way to get your line at 1 is to generate a dummy series and change the graph type, The Zero line is a special case.<br /><br />I've put together an example of what I think your looking for. The issue is if you want a legend, because there's a bug in 5.3 where disabling the legend display for 1 series does not work (done by setting it's shape to null) (it's still in the 7.1 beta).

ah. bless you! i see where you set the axis limits. i'll use those , and bag the single line
until 7.2, as i want no legend.

Susan the line setLegendDisplay(false); turns the legend off altogether.

ALL the documentation for the java API is in
the devstudio/bin directory. JavaGraphAPI.pdf

Indeed, the material is in the Perspective for Java Programmer's Manual(DN2100945.0901).

Have a good day,
Jennifer

JG, I pulled down the manual, all 900 whopping pages!, and am still having trouble finding color for axis labels.
My xaxis is ordinal, and the rotate worked,
setO1LabelRotate(0); and you taught me how to do font sizes..working so well.
But color i can't figure out.
Can you help me once again? thanks.

And it's not the best written book in the world.

What you need is

setFillColor(item(),new Color(255,102,0));
where item is the thing you want to change the color of, so for example

setFillColor(getY1Label(),new Color(255,102,0));
setFillColor(getO1Label(),new Color(255,102,0));
setFillColor(getLegendText(),new Color(255,102,0));

Changes the color of the x and y axis text or scale and the legend text. The numbers are the RGB codes for the desired color.

I have similar requirement with API. across-total is displayig the graph total in y-axis. I want to display the label as "Total" for this group.

Is there any api to set label without hardcoding the index of "Total" as y-axis values are dynamic?

Thangam, I cannot visualize what your graph looks like. Can you save it as a gif and post it so that I can see.

By the way the 5.3 documentation is DN4500605.0904
Not the number quoted by docservices which is rather old. And the new documentation is 1345 pages.

Sorry about that. JG is correct. There's a new version of Perspective for Java Programmer's Manual. The title was changed so it's now called "WebFOCUS Graphics."

The WebFOCUS Graphics manual is also available in HTMLHelp format, so you don't have to download the entire PDF file.

If you are an InfoResponse customer, you can see the HTMLHelp version on theTechnical Documentation Library

Regards,
Jennifer

JG, can you teach me how to do
ACROSS MYVAR1 NOPRINT ACROSS MYVAR2 AS ''
my xaxis is ordinal
so the labels don't plot in alpha order
and i need MYVAR1 to organise them.
Unfortunately, this doesn't seem to work in GRAPH FILE.
My workaround is to append myvar1 to myvar2
but thats so ugly.
Can you help me, once again??
tia.

JG, Not able to attach image

My graph has status in x-axis and sku count in y-axis. x-axis I have active, non-active. For active-3 skus, for non-active-4 skus. Total shouws 7 skus. I am not able to display "Total" label in x-axis for 7 skus. status is not fixed as active, non-active. It will change.

Problem is that GRAPH FILE does not parse like TABLE FILE and so computes, NOPRINT etc. do not work in the same way.
However you can force the sort
order by using ACROSS COLUMNS.
To do this in a dynamic fashion you need to create the COLUMNS component as an include.
try the following approach.

  SET HOLDLIST = PRINTONLY
DEFINE FILE CAR
NSEATS/I5=IF COUNTRY EQ 'ENGLAND' THEN SEATS *(-1) ELSE SEATS;
ONELINE/I5=1;<br />DNA/A56=' AND ';
DUMMY/A12 ='''' || 'DUMMY' || '''';
END
TABLE FILE CAR
SUM<br />COMPUTE AFIELD/A12= '''' || COUNTRY || ''''DNA
-* sort the output by your primary 
sort order followed by the actual 
column that you want using NOPRINT 
on BOTH BY TOTAL 
DEALER_COST  NOPRINT BY COUNTRY 
NOPRINT ON TABLE SAVE FORMAT ALPHA END -RUN-* set a variable EQ &LINES -SET &
VISIBLE=&LINES; GRAPH FILE CAR
SUM NSEATS FST.ONELINE AS ''ACROSS COUNTRY  AS '' COLUMNS<br />-INCLUDE SAVE
DUMMY ON GRAPH SET 
LOOKGRAPH VBA ON GRAPH 
SET GRAPHEDIT SERVER O
N GRAPH SET BARNUMB OFF
ON GRAPH SET 3D OFF<br />ON 
GRAPH SET VZERO ON<br />
ON GRAPH SET GRID OFF<br />ON GRAPH PCHOLD FORMAT GIF<br />ON GRAPH SET 
GRAPHSTYLE *<br />-* you need the 
following API call to drop 
the dummy column 
I've dropped all the other API 
calls because you already know them setViewableGroups(&VISIBLE.EVAL); 
ENDSTYLE<br />END

Should do the trick for you

If the 'total' is always the last bar (for instance 3) then
setGroupLabel(2 ,"Total");<br /><br />should
work. However if the number of bars is dynamic then you need to generate the
number as a variable by doing a dummy graph request as follows

  
DEFINE FILE CAR<br />
NSEATS/I5=IF COUNTRY EQ 
'ENGLAND' THEN SEATS *(-1) 
ELSE SEATS;
ONELINE/I5=1;
END GRAPH FILE CAR SUM NSEATS
-*ONELINE AS '' ACROSS MODEL AS ''
ON TABLE SAVE FORMAT GIF
END -RUN -SET &GROUPS=&RECORDS-1;

Your API call then becomes setGroupLabel(&GROUPS.EVAL ,"Total");

ah. columns! (we need an icon for 'slapping palm on forehead..i couldahadaV8').
Thanks once again, JG.

jg, can you tell me how to change the linetype of a linegraph from solid to dotted or dashed?
simplest thing in the world...

Susan, the API functionality to create a dotted line does not work, it is planned for future release. When ? who knows.

however I have found a better way to put in your reference line.

setReferenceLine(getY1Axis(),0, 1.0);
setLineWidth(getReferenceLine(getY1Axis(),0),1);
setFillColor(getReferenceLine(getY1Axis(),0), new Color(0,0,0));


The following lines should change the appearance of the line and even though they are documented I cannot get them to work, perhaps a hottrack needs to be raised

-*setLineBasicStrokeType(getReferenceLine(getY1Axis(),0),1);
-*setLineDash(getReferenceLine(getY1Axis(),0), vectDashFloat);
-*vectDashFloat is supposed to be a java float vector array

wow! setReferenceLine...how cool it that. i'll try it.
..
update:I tried it..copied pasted your code..i'm getting :
Possible Error on getReferenceLine(,0.0)
I'm in 525...do i need to be in higher version?

My whole system is being released this week...it so swell, basic lines are red blue green, user selects data set from dropdowns onlaunch page, and then several small line graphs come out, arranged in rows/columns in hmtlform (principle of "small multiples"),but not everyone in the co has access to a color printer so i of course have to produce them in line dot dash...
Have you read the works of dr. edward tufte?
www.edwardtufte.com .. on excellence in graphic presentation? he's the guru whose work i try to get wf to emulate.
I'll try your lineBasicStroke type...i didn't even see that in the doc, which, alas, seems to be arranged alphabetically instead of by concept.
thanks very much, again.

Susannah

Judging from your presentations at SUMMIT and FUN, your company is very lucky to have you doing this work.

Have you tried implementing Tufte's Sparklines in WF? These seem to provide considerable bang for the buck in a small amount of space.

Wouldn't it be great if IBIers would visit Tufte's site to gain insight into why we might want more meaningful presentations of data than just the same old "pictures" every other BI product offers?

Suzy

Suzannah,

The new graph engine introduced in Release 5.3 has the ability to render a reference line. I think this may do what you want with regard to your single line requirement. Below is a sample of Graph API code to generate a reference line:

-* The numeric arguments for setReferenceLine() are:
-* the Reference Line Index (the first one is zero),
-* and the position of the line (in this case the position is on the Y Axis.
-* As you mentioned that your Y axes will run from-1 to 3 I set the line at 2)
setReferenceLine(getY1Axis(), 0,2);
setLineWidth(getReferenceLine(getY1Axis(),0),1);
setFillColor(getReferenceLine(getY1Axis(),0), new Color(150,150,150));
setDisplay(getReferenceLine(getY1Axis(),0),true);

Larry

hi suzy.."sparklines" no, i'm not familiar with the term. i've got all three books...i'll go find! maybe you can show me at Summit? Thanks for the kind words. Wouldn't Tufte make a great Summit keynote speaker? Lets suggest.

Larry, what about linetypes solid dotted dashed?
