Please help me , I followed the direction to set up cewolf. I created the a lib folder and put all the jars in there. However I put the other classes here:
C:\Tomcat 4.1\webapps\faults\WEB-INF\classes\de\laures\cewolf

Sorry. I just realized that I was logged-in as a "developer" not as the APEX Admin which, of course, is why I couldn't find the "security" option. I had too many windows open at once.

Basic line chart help

I am relatively new Crystal reports 11 and am having problems creating a lsimple ine chart. I am trying to trend two types of network errors over time. The type of errors are in one field and the values are 1 or 2, I have two formulas, one converts a 1 to alarm and another to convert 2 to warn. I thought this would be simple but no mater what I've tried I end up with one chart that plots two lines that have the same values (instead of one for alarms and one for warns) or two charts that correctly plot the events over time. I need both events on one chart to compare them. There must be something fundamental I'm missing.
In the chart expert I have, on change of show @Alarm and @Warn. I've tried it with and without groups.
Any help will be greatly appreciated.

Tonus,
Try just creating 1 formula instead of 2.
Try this:
if {field.value}=1 then
"Alarm" else
"Warn"
Now use this formula in your chart expert.
I hope this helps,
Regards,
Zack H.

i need to create a time-series chart (with two lines o variables in this case, cause i have 2 different template_id (1,2)) that shows on the X axis datatime and value on the Y axis. My query is shown bellow:
Select * from data_valueorder by template_id, datatime;
of course i need to filter... so, on the chart properties i created two series:
- first one:
Series Expresion: "template = 1"
X Expression: $F{datat ime}
Y Expression : ( $F{template_id}.equals(new Long(1)) ? $F{value} : null )
- Second:
Series Expresion: "template = 2"
X Expression: $F{datat ime}
Y Expression : ( $F{template_id}.equals(new Long(2)) ? $F{value} : null )
the thing is, i doesnt show the first line... actually, if i had more template_id entrys (lets say 1,2,3,4,5).... my chart always displays the values of the last template_id (5 in this case)..
can anyone PLEASEEE help?

Hello
(1) Before charting time or duration values, I convert them as decimal numbers representing a decimal number of days (you may choose a decimal number of hours or a decimal number of minutes).
Here is what I get.
It appears that the chart tool defaults to the orientation where there is the greater number of values.
This is the case for Graphique 1 and for Graphique 2
Clicking on the orientation button I may change the behavior accordingly as I did for Graphique 1 rotate and Graphique 2 rotate.
I don't see any oddity here.
Just for info, to build the transposed tables, I didn't used the TRANSPOSE() function but formulas like:
B9 =OFFSET($D$2,COLUMN()-COLUMN($B$9),ROW()-ROW($B$9))
fill down, fill right
G9 =OFFSET($I$2,COLUMN()-COLUMN($G$9),ROW()-ROW($G$9))
fill down, fill right

Zero or Empty cells in Pie-Charts (HELP!)

I need to make a pie-chart that shows the names of the labels - unfortunatly there are some cells that have no values (?)
But whenever i want the labels to showup in the pie-chart, all 'empty' or '0' cells clutter up the pie-chart, filling it up with zero's and several layerd labels on top of each.
i know, i can hand-select those rows that do have non-zero values - but that is 'hand-work' and that is not what we are up to at all.
i tried to trick with filtering out the rows, but it does not affect the chart
i tried to delete the contents of the cells, but still, because it has a label in the left column, it shows up
i tried to fool Numbers by producing an ERROR() in the calculation
but nothing seems to get rid of the 0% in the pie-chart
please help, i'm running out of time

Hello
What I describes here
http://discussions.apple.com/thread.jspa?threadID=1202856&tstart=0
for a line chart apply to 3D pie charts too.

Chart Help

I was wondering if anyone know anything about charts?
I want a real time chart like this example http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-7c6f.html, but I want
it to "run" from right to left and not keep all the data on the chart. Old data will disapear out to left side of the chart.
Is this possible with the example in the link, if so, how?
Thanks!

Kipp,
When you start a new document, the blank template incudes a table with 1 Header Column and 1 Header Row. They are filled with a gray background so you can tell them apart at a glance, but it isn't the gray that makes them a Header, the color just gives you a hint. Not seeing the gray column A is what tipped me off. See SG's instructions for converting a Body Column to a Header Column. Most newer, and some older, users don't want to be bothered with deleting unwanted Headers, so they start their documents in Column B. I'd recommend that you customize your Table format to your needs rather than the other way around.
Just converting Column A to a Header column won't solve your problem. You will have to Delete the Charts, Convert the first Column to a Header and then reestablish the charts.

SVG Chart: HELP!!!

I am trying to create a pie chart like this one http://htmldb.oraclecorp.com/pls/htmldb/f?p=558:6:10625455385870944353:::::
However, I am not sure what the code should be to make the chart change as the user selects different options from the drop down menu.
I am also having trouble calculating an SVG chart that shows percentages. This is the code I am using, based on the tutorials:
select null link, COMPETITORS_1 label, count(COMPETITORS_1) value
from ORACLEDIRECTCAMPAIGNS
And I get this error ORA-00937: not a single-group group function.
Please help! Thanks!!!

Try taking the semicolon ";" off the end of the SELECT statements.

Horizontal Stacked Bar Chart Help!

I'm looking for a platform independent solution to a horizontal stacked bar chart. I'm interested in seeing solutions in pure CSS3, HTML5 and JavaScript. I have a solution currently coded in ASP.NET MVC4 that I want to add this chart to. I want to be able
to pass or represent two pieces of information on the chart. For example, a company can only have 20 users. They are currently have 5. I want to show a bar that has 1/4th of the bar in a color, and the other 3/4 in another color. A complete easy
to use parameterized javascript block would work, but I have been attempting to accomplish this in CSS3... and failing quite miserably! If anyone feels like sharing, I would be greatful! Thanks!

Only One Label is Formatting as Percent in a Pie Chart - Help

I'm having trouble with a pie chart. I have only two values in the chart and have added labels. When I preview the report both labels display correctly. However, when I right-click the labels in design view and select the #PERCENT option
from the Series Label Properties and the preview the chart, only one label is actually formatted as a percent.
I don't get it?
I've followed the steps in other forum questions to get around this but nothing works. I am in a hurry and really need this to work properly, can someone spell this out for me?
This is what I see in preview currently:

Web Part Chart Help

I have set up a Web Part Chart as a bar chart based on Desk Utilisation. Does anyone know if there is a way I can change the colour of an individual bar if the value is greater that a preset figure say 100%.

I don't believe so. Honestly the Chart Web Part is not very good (removed in 2013). I'd suggest exporting the list to excel and saving the .iqy (query) file and use it as a data connection. Then create a PowerPivot chart and save that. Set it to refresh
the data on open. Now you have a better tool for charts.

Drill down chart help mee

Hi....
Can anyone explain to me, how works the chart drill down sintax, I not understand for example:
SELECT 'f?p=&APP_ID.:156:&SESSION.:GET_DETAIL_REPORT:NO::P156_DEPTNO:' <=====what is it?? is an item?? and what is inside of this?
|| deptno LINK,
deptno, COUNT (empno)
FROM emp
GROUP BY 'f?p=&APP_ID.:156:&SESSION.:GET_DETAIL_REPORT:NO::P156_DEPTNO:'
|| deptno,
deptno
And you know the GET_DETAIL_REPORT???
THANK YOU SO MUCH
Claudia

Claudia,
In your number 4, P156_DEPTNO, you say is an item...
but is an item hidden??? And if so then is a sql
query??That's an item defined on the detail report that your link will jump to. You have to define that detail report first, including creating an item on that page that you'll use to pass the parameter. You also have to edit your detail report's query to use that item.
Check out the example code for a Master-Detail report in the 2-Day Developer Tutorial, including moving your mouse over the link from the master edit button to see the syntax. The chart is doing the same thing.
Good luck,
Stew
