Histogram using CL_GUI_CHART_ENGINE
Hi,
I am trying to build a histogram using CL_GUI_CHART_ENGINE as a better looking chart than the standard histogram chart in QGP1(2) transactions. First of all even if I use the same class as QGP1(2), the columns are showing up at different locations.The other problem is bell curve (gaussian distribution curve) is not being displayed sometimes, and other times, it shows up as a very small curve.
Are there any parameters that can be tweaked to manipulate the bell curve. I could not find any parameters. I can send you the config/data xml files, if you need any additional informations. The Data file is a simple histogram xml file with the y-values, and nothing more.
Thanks.
Albert
Hi All,
SAP has fixed the problem. You have to download the latest GUI patch. Scaling issue has been resolved, and SAP has also provided a GausianScale parameter that will allow us to manipulate the height of the bell curve. By default it 30% of the maximum bar height.

Hi all,
Kindly guide me how to create histogram in JavaFX ?
is it possible to do it using BarChart? how to label the bin edges (ticks)?
Thanks,
GunjanDownload the JDK 8 samples.
Find and run the JavaFX 8 Ensemble application within the sample.
Try out the audio bar chart in the application.
See if the audio bar chart gives you the information you need to build your chart.

Use awt to display histogram in a JSP?!
Hi,
I have been searching the web in the area awt and JSP and it feels like I am fumbling in the dark. I want to display a histogram, which shall be updated continuously from a database. I have found a program example, which is creating a histogram using awt. This example is using a frame and my question is, could I import this frame to my JSP or is there a way to make use of the awt class in a JSP and display, draw the histogram directly in my JSP page?
Thanks in advance!The only way to use AWT in a JSP would be to put the
AWT in a applet and put the applet in the JSP. -
Create Gantt-Chart by using class CL_GUI_CHART_ENGINE
Hello,
my goal is to create a Gantt-Chart by using CL_GUI_CHART_ENGINE .
I´ve copied report GRAPHICS_GUI_CE_DEMO and tried to modify its XML data in order to get a Gant-Chart
but I failed. I´ve also used SAP Chart-Designer to get an executable customizing for the chart engine
but this way was unsuccesful too. Every time the chart shows no data...
Is there anyone who has an example (code, docu, xml) to create a Gantt-Chart?
Thank you.
Kind regards,

Created a pdf file showing a graph generated with CL_GUI_CHART_ENGINE
Hi Experts!
Please, anyone has already created a pdf file showing a graph generated with CL_GUI_CHART_ENGINE??
Could anyone help me with this requirement?
Thanks in advance,
Best regardsHi,
I searched and found another solution, because with the code from the link above I got everytime a short dump, maybe I did something wrong.
The solution works with Adobe Form
1. I used the class cl_igs_chart_engine to create a chart with my data and customizing to get the binary data of the image.
2. Convert the binary tab to xstring.
3. You can use this xstring on the Adobe Form to display the image.
Maybe the following tips are useful.
*How to get the data of chart you can see in the class
CL_TIME_CHART_SIMPLE (use cl_gui_chart_engine for the chart but class cl_igs_chart_engine for saving the image)
*How to bind the image to the importing parameter (xstring)

Why Oracle not using the correct indexes after running table stats
I created an index on the table and ran the a sql statement. I found that via the explain plan that index is being used and is cheaper which I wanted.
Latter I ran all tables stats and found out again via explain plan that the same sql is now using different index and more costly plan. I don't know what is going on. Why this is happening. Any suggestions.
ThxI just wanted to know the cost using the index.

This is data warehouse with hundreds of tousands of object.
I came to idea that we should delete majority of histograms, but usual delete via delete_table_Stats makes us
to recalculate statistics on whole table (with size 1) and thats is huge impact and time consuming task.
So is there any way I can 'update' dictionary via dbms_Stats.set_column_stats, and make histograms to disapear ?
Regards.
Gregregather the statistics on the table with method_opt=>for all columns or for all indexed columns or whatever size 1
The 'size 1' directive will remove the histogram statistics.
Sorry, didn't read ur post in a hurry. Below article (http://www.freelists.org/post/oracle-l/Any-quick-way-to-remove-histograms,13) removes histogram without re-analyzing the table. Hope that helps!!!

but with only 1 bucket (i.e. no histograms).You might try the attached script, that reads the stats using
dbms_stats.get_column_stats and re-sets them, minus the histogram,
using dbms_stats.set_column_stats.
I haven't fully tested it - it's only 10 minutes old, even if Ihave
slightly modified for you another script I've used for quite some
time - and the spool on 10.2.0.3 seems to confirmthat the histogram
is, indeed, removed, while all the other statistics are preserved.I
have also reset density to 1/num_distinct, that is the value youget
if no histogram is collected.regards,

Changing color of columns in CL_GUI_CHART_ENGINE
Dear Developers,
I am displaying a Columns Graph using class CL_GUI_CHART_ENGINE. My requirement is to change color of selected columns based on their height. For example if height of the column exceepds 10, then the color of that particular color is to be made red. Is that possible using CL_GUI_CHART_ENGINE ??

Cl_gui_chart_engine Bar chart refresh
Hello,
I am using cl_gui_chart_engine to show barchart. But i want to show 10 records at one time. I manage to do the itab and xml data changing part using a button click. But when i use command call method g_ce_viewer->render, it doesn't show the updated records.
Thanks in advance.(okay, I know it's out of date, but might be useful to someone somewhere...)
As KAI said, it's not advisable to re-render or repetitively create the viewer object.
If you just re-use the existing container+object, and recall the method to set the graph:
g_ce_viewer->set_data( xdata = data_xml ).
with your new data.
In my transaction, we use this to monitor Material Usage. When the user dclicks a material in the list in an ALV grid, an event gets triggered, that researches the Material Usage for that Material, reuses the XML Transformations, then we set the data on the graph. This means that the objects don't get recreated, but the data presented to the user changes.

CL_GUI_CHART_ENGINE Graph As Email in Background
Hi All,
I am using CL_GUI_CHART_ENGINE class to display multiple graphs with custom container using splitter method ,when i am running it in foreground everything is fine i can print/save graphs seperatly.
If i use docking container to display CL_GUI_CHART_ENGINE will it run in background ?
My main problem is to send email with both graphs.
Is it possible to send email in background? if Yes please suggest a way.
As i have gone through many threads and i could'nt find the right way to do this.
Looking for some suggestions..

The default for the histogram used to be rgb view which is the one I prefer. Now it is color. In order to get rgb one must first change to expanded view to gain access to option and then choose rgb from list of options then go back to compact view. Very annoying. More annoying is the fact that it can't be saved as a desired workspace and every time a new image is opened it goes back to its default and you have to repeat the process all over again! Are there any workarounds for this? If so, I would appreciate a solution.
Not sure if that info is stored with the file being edited, or as a global pref, but if it's a global pref, they (global prefs) can become corrupted, so try to rebuild your Photoshop preferences and see if the behavior reverts to the preferred way of showing the Histogram.
If not, then it may be saved as a document preference, and in that case, I don't have any ideas. Is this Mac, or PC?
Best to move this question over to the Photoshop desktop product forum, this was posted to the Photoshop.com forum, which may not have as many desktop Photoshop using people participating.

Histogram on non-indexed columns
Hi All,
Is there any point in having histogram on non-indexed column? If we use a non-indexed column for filtering data, there will be a full table scan anyway.
Does having histogram in such column make any difference.
I am on v11.2. Are there any differences/advances in this respect in 11g ?
Thanks in advance.rahulras wrote:

Thanks in advance.Histogram used to correct estimate selectivity(~ cardinality) by CBO if there are indexes or no!.So if there are indexes then after estimating selectivity based on values CBO can be select FULL TABLE SCAN but not INDEX SCAN!.Finally histograms use when your columns data non uniform distributed(actually skewed). -
Hi all
i have created a histogram using JAI successfully for 3 banded image RGB.
how to get the histogram for a single band from that object?Technically a true histogram for a colored image would be a 3-D histogram with counts of rgb values (requiring 4-D to visualize it). But there are certain monumental problems in messing around with a 256x256x256 int array. Thus we usually go with different approaches for representing a colored image's histogram (for example using HLS space and doing a histogram of the "L" component or creating 3 seperate 256x256 int arrays representing RG, GB, RB).
Thus I'm I little curious on what you actually mean when you say
i have created a histogram using JAI successfully for 3 banded image RGBEven JAI won't be able to create a true histogram for an RGB image. In the documentation of the Histogram class it even says
For an image that has multiple samples per pixel (multi-banded images), a separate list of bins represents each individual band. Thus if you are using the Histogram class, then you in fact have three seperate histograms of each band in the image. -
Some XML customizing not displayed correctly in graphic in PDF form
Hello,
we have following problem: We want to create a read-only PDF with an integrated graphic with analytical data.
The PDF form is created with SFP. Data is extracted and the graphic rendered with the class CL_IGS_CHART_ENGINE.
We used SAP chart designer and transformed the XML into our string.
The graphic is displayed in our PDF, but some customizing settings in our XML are neglected, especially the font type, her only courier is displayed. Also some manual positions of legends don't work.
When I display the chart in the SAP GUI using cl_gui_chart_engine everything works fine, so I assume that the XML and the transformation is correct.
So where is the problem: Mime type? codepage? printing job?
Thanks and Regards
AndreasHello,
I would like to know what type of scenario do you use. Is that WD form? Or offline form?
Based on the type, you may find your solution here:
When you need to send a picture into the offline form: another image question - using Regular ABAP not web dynpro and Display a logo dynamically in adobe form
For the WD form: /people/bhawanidutt.dabral/blog/2007/11/15/how-to133-integrate-adobe-form-on-webdynpro-for-abap-and-deploy-it-on-portal
What MIME type (picture type) has your generated picture? JPG for example is ok, but for exotic types please check in your LCD (place Image on the layout and open the dialog for picture assignment, you can see the allowed picture types in there).
Regards, Otto
p.s.: What is the mentioned XML customizing? XML is the form of the femplate, but I have never customized anything IN THERE. Did you change the XML source manually? Or what type of changes are not managed correctly? -
How to monitor SQL Apply for 10.2.0.3 logical standby database
We have a logical standby database setup for reporting purposes. Users want to monitor whether sql apply is working or failed closely as it has reporting repercations.
In case of 9i databases , there was "Data Not Applied (logs)" metric which we used for alerting and paging, in case a backlog of more than 5 log files developed.
With 10.2.0.3 onwards, the metric no more exists.
I would like to learn from other, how to monitor the setup, so that if the backlog in logs shipping or applying develops, we get page.
Regards.regather the statistics on the table with method_opt=>for all columns or for all indexed columns or whatever size 1
The 'size 1' directive will remove the histogram statistics.
Sorry, didn't read ur post in a hurry. Below article (http://www.freelists.org/post/oracle-l/Any-quick-way-to-remove-histograms,13) removes histogram without re-analyzing the table. Hope that helps!!!

I also did a quick check and just using
exec
dbms_stats.set_column_stats(user,'table_name',colname=>'column_name',d
istcnt=>
<num_distinct>);
will remove the histogram without removing the low_value andhigh_value.

dbms_stats.get_column_stats and re-sets them, minus the histogram,
using dbms_stats.set_column_stats.
I haven't fully tested it - it's only 10 minutes old, even if Ihave
slightly modified for you another script I've used for quite some
time - and the spool on 10.2.0.3 seems to confirmthat the histogram
is, indeed, removed, while all the other statistics are preserved.I
have also reset density to 1/num_distinct, that is the value youget
if no histogram is collected.regards,
