Seek 2D Line and Bar Chart Graphs HOWTO

Can anyone share with me on where I could obtain/teach
me how to write 2D Line and Bar Chart Graphs ?
I like the class/program to be called from java code and not
from command prompt to plot points or bar graphs.
Please, no vendor recommendations.
I dont have the $ to purchase.
Any help is appreciated.
Thanks

I checked the web site of JFreeChart and its document
says to get premium service, it requires $.
I dont really have the $ to purchase that software.
It's a vendor product!Just to clarify, JFreeChart is free software, it is licensed under the GNU LGPL. You get the complete source code, including lots of demos, Javadoc HTML pages, an install document in PDF format, and access to the support forum for absolutely no charge. You don't have to pay a fee to unlock special features in the software, everything is there in the free download.
As a way of funding the project, we sell a JFreeChart Developer Guide which includes a lot more information about using JFreeChart. But it is only the documentation we sell, not the software.
Hope that helps,

How to draw a straight dotted line on Bar chart at 70%?

Hi
Could you please let me know how to draw a straight dotted line on BAR CHART at 70%?
Thank you

Hi,
This may vary depending on what version of crystal you are using.
Right click on the graph & go to 'chart options' & choose 'Grids'
In the grids pane go to the grids tab. From there check the 'draw custom line at' and specify where you want to draw the custom line.
Once the line is drawn highlight the line, right click and go to 'chart options' & 'selected item'.
select what format you want the line to look like (choose the dashed one).
good luck!

How to plot line and bar chart in one graph

i have one graph, but in this graph i want to plot line or bar chart using radio button selection.
can i do that...

You must have 2 data arrays or plots to get this. Make sure your plot legend is visible. Drag the plot legend vertical borders to view both plots. Select one of the plot to be bar plot (See the attachment)

How to generate control limits in control chart

I want to generate a X bar chart with control limits, sample size is Fix- 1.
SPC criterion I selected is 020 ie Task List characteristics/ Material.
1)Sampling Procedure I used- Fixed-1
2)Valuation mode I used- Attrib non conforming units/ manual.
3)Control chart I am using is 110- Shewart chart for X bar.
But when I click for control limits in chart it is saying control limits for track 1 could not be calculated.
Could anyone guide me, how to generate control limits for this graph. Sammple size will alwyas be 1.
Please let me know should I change control chart type in this case.

Hi Jaison,
You should use valuation mode - SPC valuation in sampling procedure.
Also you have to use sampling procedure with inspection points.
as practically every hour or depending on the frequency decided we collect the measurements and calculate the SPC.
now after correction in the sampling procedure create new inspection lot and check SPC.
try out and revert.

Anil

How to thicken the line in Line Chart?

Post Author: leongcy23
CA Forum: Charts and Graphs
I created a line chart and everything is smooth. But there is one thing that I'm not satisfied, which is I can't thicken the line of the chart. I try to look for Help, but it didn't show anything. From what I explore and try, I only can enlarge the marker, but not the line.
And another issue is, can I choose the color for the line? Because the report will auto generate the line with color that is not clear which is yellow which border me so much. I wonder is that I can choose the color of the line.
I really appreciate for someone that offer help. Thanks
Anson

What version of Crystal are you using? I can click on the line to highlight and then right click to get the option to format line. You can then choose color and line thickness. I'm using Crystal XI. It may take a few trys to highlight the line.. you have to hit it just right but I can't imagine this wasn't available in earlier versions.

I just opened an old file that I created with Crystal Excelsius and I see the stacked bar chart visible in the components window of my old files.
Why has stacked bar chart disappeared from the components window in my new files? It seems many of the components have "disappeared" including stacked bar, candlestick charts, area charts and most of the background components.

In office word bi publisher plugin, load the xml, the chart can be generated.
The above exception only occurs in some linux and solaris platforms, but never occurs in windows.
The following plateform throws exception.
Oracle Linux Server release 5.6 + java version "1.6.0_25"
The following plateform doesn't throw exception.
Enterprise Linux Enterprise Linux Server release 5.4 (Carthage) + java version "1.6.0_05"
The strange thing is in those platforms which can throw exception, if the code is not running in EJB, the chart still can be generated.
In other words, if the normal web or standalone app invokes that program; the chart can be generated.
The java code is as below.
 public static void generate(String inputXML, String pdfTempPath, String outputPDF) {
 Reader reader = null;
 try {
 File xmlFile = new File(inputXML);
 reader = new BufferedReader(new InputStreamReader(new FileInputStream(xmlFile), "UTF-8"));
 ByteArrayOutputStream tmpXSL = new ByteArrayOutputStream();
 RTFProcessor rtfProcessor = new RTFProcessor(pdfTempPath);
 rtfProcessor.setOutput(tmpXSL);
 rtfProcessor.process();
 ByteArrayInputStream in = new ByteArrayInputStream(tmpXSL.toByteArray());
 FOProcessor processor = new FOProcessor();
 processor.setData(reader);
 processor.setTemplate(in);
 processor.setOutput(outputPDF);
 processor.setOutputFormat(FOProcessor.FORMAT_PDF);
 processor.generate();
 catch(Exception e) {
 e.printStackTrace();
 finally {
 try {
 if(reader!=null) {
 reader.close();
 } catch (Exception e) {
Can anyone explain why this exception is thrown?
Thanks a lot.

Hello Tux Dueñas,
I think you need to have ACL's setup in Oracle 11g in order to be able to connect to the BI Publisher server. Check the following link on how to setup ACL's in 11g...

Dynamically Generating Charts

I need to be able to generate charts in APEX 3.01 from a SQL query which doesn't exist until it's built at runtime.
The query is of the form:
SELECT null link, x label, count(*) value FROM y table GROUP BY label, value ORDER BY 3 DESC
x and y are the dynamically generated bits. I build the query using a PL/SQL anon block:
DECLARE
myquery VARCHAR2(4000);
BEGIN
myquery := 'select null link,';
myquery := myquery || :P39_MYCHARTQUERY;
myquery := myquery || ' label, count(*) value from ';
myquery := myquery || :P39_MYCHARTTABLE;
myquery := myquery || ' group by label, value';
myquery := myquery || ' order by value desc';
htp.print(myquery);
END;
The problem is, APEX charts will only accept a straight SQL query, not a PL/SQL block. I've tried putting the block into a hidden field (Display as Text, PLSQL version) and referencing it using substitution strings (&variable_name. style), but this doesn't seem to work. APEX is complaining about my generated SQL query:
"Error in rendering chart: ORA-06561: given statement is not supported by package DBMS_SQL"
The SQL looks correct. I have no idea what the problem is. Can anyone help?

That's an interesting blog post. I'll have to dig around in SQL Workshop to see how to implement it. Modifying it to be multi-variable looks like it shouldn't be too difficult. Teaching myself about what packages are and how to use them will be the hard part.

Generating charts in batch

Hi!
I have the requirement to generate charts/graphs as image files in batch (hundreds of them in one batch). This chart images should be stored in table's blob column or in files on server's file system and later used for viewing on "static" web pages. This batch will be triggerd by cliking on button by a user or without user interaction from scheduler.
How can ADF charts can be used for this purpose?
So, is there any Java API for generating charts without GUI (like ChartDirector for JSP/Java http://www.advsofteng.com/cdjava.html)?
Regards,
Sašo Celarc

I found the oracle.dss.graph.Graph (http://download.oracle.com/docs/cd/E14571_01/apirefs.1111/e12063/oracle/dss/graph/Graph.html). As understood this package exists behind ADF Charts? Am I right?
Are there any useful examples how to use methods from this package?
