Apex 3.1 and Custom Flash Charts

I am having difficulty getting to the point where my custom flash charts can be displayed. I have Oracle 10.2, over OHS to Apex 3.1. I cannot post any of the config files or code here because it is a different network, so I realize it will be hard to troubleshoot; and I apologize in advance.
I would use the canned Flash charts, but my application displays data much like MS Outlook's multi-user calendar does. The chart has to be color coded, similar to Outlook's Busy vs Tentative etc. It has to show multiple events at various times, including overlapping times. And it has to handle schedules for multiple people. Lastly, there are of course gaps in the schedule, because no day is comprised entirely of meetings. That is why I felt I had to do it manually.
I wrote XML/SVG code to do this previously, with HTML DB 1.5, and it worked fine. But Flash is the way we are going now, and I can't use SVG anymore. (Besides, Adobe says SVG will no longer be supported next year.)
I followed the thread of April 07 in which MAdelfio posted suggestions, but I can't get it right. I did everything listed except I never included the <data>...</data> code, because I am not sure where it goes. I have a custom written stored proc, exactly like in the thread, and I pass it all the args that apex_util.flash wants. I get a malformed XML message when I try to display the chart. That seems like it should be a very straight forward error, but I can't figure out where to look. I have been using 1.5 for about a year, and last month upgraded to 3.1.
Any suggestions on how to troubleshoot this? Or, failing that, any simple examples that display Flash charts in which the code was generated by a stored procedure?
Thanks,
Michael

I'm sorry about not being able to provide all the info you need. Since it is on a totally separate network, with no access to the outside world, the only way I can do it is to print and retype everything. So I was hoping that someone could just provide suggestions as to where to look rather than providing answers. I understand that it is impossible for you to solve my problems, especially when you have been given no real information. And I don't want to keep you guessing -- I'd love to be able to just show everything and ask for help; I just can't.
Anyway, I am trying to use only those facilities provided with Apex. I do not have any 3rd party tools except for Perl. I am using the standard shockwave flash plugin for Mozilla. The way I did it with SVG was to create a stored procedure that generated an XML file. I put a button on the page that ran the stored proc and then redisplayed the page, with an HTML region. That region included an iframe, where the source was a perl script that merely regurgitated the SVG script (for some reason I could not get the iframe to accept XML as a source, so I created send_svg.pl, which merely outputted the named SVG file).
The format I followed was in this thread: Re: Custom Flash Charts
I even created a replacement proc for APEX_UTIL.FLASH with the exact output as the thread, knowing that even if it worked I'd still have a ton of work making it produce my chart. But once I can get the infrastructure right, I feel I can write the flash XML.
Maybe the easiest thing is to scan that thread I referenced and tell me if it is still accurate? That is, could anything have changed in 3.0.1, or should it still work? It is possible, maybe even likely, that I made a mistake retyping all that stuff, so maybe just verifying that it SHOULD work is a good start.
Thanks again, and sorry again.

Custom Flash Charts

Hi,
I'm having some problem due to margins in Custom Flash Charts. APEX 3.0.1
First i created a new chart (Horizontal 3D Column) that I let all margins to 0 but inside the rendered Flash it shows a lot of blank space between the x-axis and the bottom of the chart, tried negative values with success.
Then I changed to Customize the Flash Chart, and the margins are not "used" anymore, like APEX is not using the values is the margin fields, and i can't figure out how can I put the values of the margins that I wan't to inside the xml/object/embed...
This is my first post but I'm working with APEX since the APEX 2.0 and we have an application of managing credit cards, private labels and other types, here in Brazil.
TY,
Guilherme

Guilherme,
You are correct, the chart margins are not used anymore when you select "Use Custom XML". So, like the other regions that no longer apply, they should not be shown when that option is selected (and this is a known and logged bug).
To achieve the same effect as the margin settings, you can edit the chart XML, and change the values inside the <chart_area> tag. Or you could disable custom XML (losing any custom changes you have made), find the margins you like, then enable custom XML again (the new custom XML will respect the new margins).

Dynamic trend line on flash chart

Hi,
How could we reference an apex item on the custom XLM chart? I intend to add a dynamic trend line using
<objects>
<line value="&PXX_." text="trend line" color="0xFF0000" thickness="1" alpha="100"/>
</objects>
but it doesn't work. Could somebody guide me to the right direction.
And to add, anybody have integrated or call an statistical process control (SPC) chart in apex?
Thanks in advance.

You can create a process, create the entire XML string in the process, and set the resulting XML string in the Custom XML area. We did something similar and seems to be working fine.

Detecting Loaded Flash Chart

I have a page with a report region and a flash chart. I created a printer friendly template for this and in it included some script to print the page using the onload event. The problem is that when the print dialog box comes up the chart is sometimes not yet rendered so the printout shows the "Loading..." gif instead of the chart.
Is there a way to capture or test for the end of the loading of the flash chart?
Thanks,
Greg
PS Apex 3.0 with users all on IE6

Hi Greg,
Could you ever print a chart, just from the browser?
In my understanding this is not yet possible in the standard APEX implementation. Anychart 4.2 is a lot better in this, but that's not yet in APEX 3.0.
However if you think it's just the loading, why not have a button on the page that does the print? So you're sure it's loaded? It won't be one click like you're trying to implement, but 2 click.
Alternatively I'm thinking about pausing the javascript or working with 2 pages. Like a master and detail and you load the chart in the detail and print from the master.
I look forward to your reply.
Regards,
Dimitri

Integration with other flash chart product

Hi,
I am currently working on an APEX site development that utilize flash charts in some reports. However, the AnyChart product that is integrated with APEX is not sufficient in achieving the layout we desire.
My supervisor is interested in another flash chart product called "FusionCharts". I would like to ask where would I find manual / instructions on how to create new components or alter the existing flash chart component in APEX so that FusionCharts can be used instead of the existing AnyChart.
If anyone can share their integration experience of another flash chart product with APEX, I would greatly appreciate it.
Thanks in advance for the help,
Nelson

Hi Nelson,
You can't replace the current Anychart with FusionChart, but you can upgrade to a newer version of Anychart if you want.
If you want to integrate FusionCharts, you add javascript and a flash file to your page and provide xml (for ex from a process) to it. I believe Scott Spendolini had these steps in his presentation of ODTUG, which you can download from that site.

Dimitri

Pagination for the flash chart

Hi,
I have a apex application where in one page I display certain value (in tabular format) based on few criteria and also in the same page for the same criteria I have a flash chart which should show the same values (as that of the tabular format) in chart. Now the tabular format is a separate region and the flash chart is another separate region. The tabular values are shown in multiple pages if the number of rows returned are more certain value (say 15). I want the flash chart to follow the same pagination logic as that of the tabular records but unable to figure out how i can achieve the same.
Please help.

Dipankar

Hi,
Do i need to provide more information on this?

Date Picker Result Used in Query for Flash Chart

Hello,
I'm creating a flash chart using an SQL Query. The query uses two date pickers for the beginning and ending date of the data the query returns. For some reason the substitution string for the data pickers do not work and do not return any data. If I hard wire the start and end date to something like '12/01/2008' and '01/31/2009' the query and the flash chart work just fine. When use the string representing the data pickers (:P65_BEGIN_DATE and :P65_END_DATE) the query does not return any data. Is there some problem using substitution strings in queries for flash charts??
For what it's worth here is the query. (Look near the bottom to see where I reference the data pickers):
SELECT 'Link',
to_char(Day, 'Mon DD'),
((Count("Item Number")-Sum("Devaition"))/Count("Item Number"))*100 as "Precentage"
from
(SELECT
to_date(concat(substr(F4140.PICSDJ, 1, length(F4140.PICSDJ)-3)+1900,
substr(F4140.PICSDJ, length(F4140.PICSDJ)-2,3)), 'yyyyddd') as Day,
F4141.PJLITM AS "Item Number",
sum(F4141.PJTQOH) AS "Sum Qty On Hand",
sum(F4141.PJTQCT) AS "Sum Qty Counted",
(decode(sum(F4141.PJTQOH)-sum(F4141.PJTQCT), 0, 0, 1)) as "Devaition"
FROM F4140 INNER JOIN F4141 ON F4140.PICYNO = F4141.PJCYNO
WHERE (((F4140.PICYCS) In ('40','50')) AND ((F4141.PJCCCD)='1'))
GROUP BY to_date(concat(substr(F4140.PICSDJ, 1, length(F4140.PICSDJ)-3)+1900,
substr(F4140.PICSDJ, length(F4140.PICSDJ)-2,3)), 'yyyyddd'), F4141.PJLITM
HAVING to_date(concat(substr(F4140.PICSDJ, 1, length(F4140.PICSDJ)-3)+1900,
substr(F4140.PICSDJ, length(F4140.PICSDJ)-2,3)), 'yyyyddd')
between to_date(:P65_BEGIN_DATE, 'DD-Mon-YYYY') and to_date(:P65_END_DATE, 'DD-Mon-YYYY') )
group by Day

I look at the debug output without changing anything and I am not really sure where the two date pickers are being populated. However I do have defaults set up for each datepicker of:
P65_BEGIN_DATE: to_char(sysdate - 30, 'DD-MON-YYYY')
P65_END_DATE: to_char(sysdate, 'DD-MON-YYYY')
and the dates I would expect show up in the date picker.
Also I created a Computation of Before Header type with the following PL/SQL expression:
to_char(sysdate-180, 'DD-MON-YYYY')
and I see the following output when in debug mode:
0.05: Computation point: BEFORE_HEADER
0.05: ...Perform computation of item: P65_BEGIN_DATE, type=PLSQL_EXPRESSION
0.05: ...Session State: Save "P65_BEGIN_DATE" - saving same value: "03-AUG-2008"
0.05: Processing point: BEFORE_HEADER
So I think the datapickers are being populated but the flash chart is still not working.

The flash chart Link not opening in oracle Apex 4.1

I have created a flash chart (Pie chart ) on the latest version 4.2.
Everything is workinfine when I have created a hidden item and associated a computation to it and added that in custom color option in chart attributes
I am able to customize this again in this version
But When I have done same thing in Apex 4.1
I am able to see the output .but When I try to change the color and click on chart attributes it throws an error showing no data found
Kindly help me in solving this error .

Hi,
To assist in resolving your issue, could you please outline the steps you've carried out in your 4.1 environment? Also, could you please confirm exactly what version of APEX you are referring to - 4.1.0 or 4.1.1?

Flash chart error: scroller position should be positive and integer

Hi
I am periodically getting this error when running a flash chart.
It seems to be related to the amount of data that I am using.
Any Idea whats causing it and how to resolve it
Keith

This only happens when using custom xml. If I change it to use the built-in xml, I get a no data found message.
That happens even if i just reset the custom xml.

Line thickness in Apex 4.02 flash chart for Legend

Does anyone know how to set Line thickness in Apex 4.02 flash chart for Legend?
My users can read the label fine, but the part where it shows the line color is very small and hard to match to the chart.

Many attributes can be set in the Chart Attributes page Custom XML section. Line thinkness. Legend font size, height and width. But I haven't found a setting for the "icon" size. Even thought I increased font size and the size of the Legend on the page, the legend "lines" remained unchanged in size.

Apex flash charts with date values on the x axis

I am playing around in Apex 4 using flash charts and having a bit of troubles playing with dates on the x axis on a 2d line chart.
What I am trying to achive is a values plotted across the chart and the date/time values are not a constent (ie not continually say 1 hour apart) hence why I want to use a datatype of date.
In the SQL below:
select null as link, sysdate -2 as value, 0 as label from dual
union
select null , sysdate -2+1/24 , 1 from dual
union
select null , sysdate -2+2/24 , 2 from dual
union
select null , sysdate -2+5/48, 1 from dual
union
select null , sysdate -2+3/24, 0 from dual;I get a 2D Line chart but each date/time value is equally space apart (ie sysdate -2, sysdate -2+1/24, sysdate -2+2/24 and sysdate -2+3/24 should be 1 unit apart and sysdate -2+5/48 should be half way between sysdate -2+2/24 and sysdate -2+3/24).
I think I have to use custom xml. Using http://www.anychart.com/products/anychart/docs/xmlReference/index.html and http://www.anychart.com/products/anychart/docs/users-guide/DateTime-Axes.html I edited the XML and changed:

Can anyone see what I am doing wrong or point me in the right direction? Thanks in advance.

This will be a little bit lengthy answer, but I guess it will be easier to understand what I meant to say.
I created a table that contains values you used as a data source (just to make my life easier):
SQL> alter session set nls_date_format = 'dd.mm.yyyy hh24:mi:ss';
Session altered.
SQL> select * from test;
VALUE                    LABEL
12.10.2010 09:03:45          0
12.10.2010 10:03:45          1
12.10.2010 11:03:45          2
12.10.2010 11:33:45          1
12.10.2010 12:03:45          0
SQL> alter session set nls_date_format = 'hh24:mi';
Session altered.From now on, we'll see only hours and minutes.
Step 1: current and previous values - difference in number of MINUTES
SQL> select t.value,
2         lag(t.value) over (order by t.value) previous_value,
3         (t.value - lag(t.value) over (order by t.value)) * 24 * 60 minutes_diff
4 from test t;
VALUE PREVI MINUTES_DIFF
09:03
10:03 09:03           60
11:03 10:03           60
11:33 11:03           30
12:03 11:33           30Step 2: a little bit of calculation:
- TIME_SPAN: how many minutes are there between MIN and MAX date?
- MIN_DIFF: what is the minimum time difference (minutes)?
- SLICES: how many time slices do we want on the x-axis?
SQL> select
2    min(x.value) min_val,
3    max(x.value) max_val,
4    min(x.minutes_diff) min_diff,
5    (max(x.value) - min(x.value)) * 24 * 60 time_span,
6    (max(x.value) - min(x.value)) * 24 * 60 / min(x.minutes_diff) slices
7 from (select t.value,
8               lag(t.value) over (order by t.value) previous_value,
9               (t.value - lag(t.value) over (order by t.value)) * 24 * 60 minutes_diff
10        from test t
11       ) x;
MIN_V MAX_V   MIN_DIFF TIME_SPAN     SLICES
09:03 12:03         30        180          6There's 180 minutes between 09:03 and 12:03; minimum time difference in our TEST table is 30 minutes, so - we want to have 6 time slices on the x-axis (180 / 30).
Step 3: row generator technique: let's create time values that are missing:
SQL> select y.min_val + (level - 1) * y.min_diff / (24 * 60) val
2 from (select
3          min(x.value) min_val,

I tested it - it displays something which means that it should work for you too (unfortunately, this forum doesn't accept attachments so that you could see it). Now, I can't tell whether that's what you need or not, but - if the idea itself is OK, it can be adjusted (I hope so).

Flash chart and multiple Y-Axis

Hi,
I have to create a flash chart with a bar and a line graphic in 1 graphic output
The left Y-axis should show the values of the bar (i.e. 0 - 20.000) and the right Y-axis should show the percetage value of the line graphic (0 - 100).
How can I scale the different values and order it th left or right like EXCEL (APEX 4.1)
Please help me
Regards,
Siegwin

Hi Siegwin,
thanks for providing access to your workspace. The reason that that second line is not behaving as you expect is because that series of the chart is not associated with the extra Y-Axis. As I mentioned in my previous posting, the extra Y-axis only gets associated with the second series of your chart. In your case, you're actually looking to associate series 2 and 4 with the extra Y-axis. In order to achieve that behaviour you could do one of the following:
*1*. Hard-code the data in your custom XML region, ensuring you update the XML tags for the 4th series to look as follows:
<series name="BX old failurre" type="Line" color="0xDBDC25" y_axis="extra_y_axis_1">instead of how it is currently generated for your chart on Page 1:
<series name="BX old failurre" type="Line" color="0xDBDC25" >
NOTE: the extra Y-axis will only be associated with the series where the attribute y_axis="extra_y_axis_1" is included.
This option is not ideal, because you are hard-coding data in the chart, which won't be updated to reflect any changes to the underlying data.
*2*. Split your chart out in to two separate charts instead of attempting to represent them on one, as done on Page 2 of your application. NOTE: the first chart is using some custom XML to set the maximum value of the extra series to 100.
*3*. Generate your own <data> tags, to ensure that the extra Y-axis is associated with your selected series. This would require doing something similar to the Thresholds example here: http://apex.oracle.com/pls/apex/f?p=36648:35 - where you are basically overriding the #DATA# substitution string for your chart and replacing it with your own <data> tags.
In a future release, we'll look at exposing options on the Chart Attributes page to allow for the setting of attributes specifically for the extra Y-Axis, and also allow for the specification of which series the extra Y-axis should be associated with. In the meantime, I think Option 2 above is your easiest option.

Hilary

Flash chart and names

Hello everybody,
I'm using an stacked 2D colum flash chart in my application in order to show all errors occuring through a week. Everything works fine, the data is showing up, but there's still one little problem:
The bars of the chart are shown with their names and values on them. But I want to hide this information and just show the bars.
If I use a stacked 3D column, the names aren't displayed. I guessed, that I could fix this, by using a custom XML and change some settings, but I can't figure out, which is the correct one.
Here's the XML, I use, it's the standard presented to my by Apex. I'm using Apex version 3.1.1.00.09, with the standard anychart, delievered with it. And I can't update it with the anychart integration kit...

Hi Dird,
sorry for my late response, but my lovely company denies the access to image hosting sites. So I had to do this at home during the weekend and there I couldn't have a look once more at my app, so it took until today :-)
I've seen, that you're not using anychart in the "standard" version that comes along with Apex, right? So it's good to know, that my XML works fine with a newer version, but I'ver got to use the version, deployed with the Apex package.
So, is there any chance, to get rid of the names on the bars with the standard version? Or do I have to wait for the next Apex version, or buy me the new anychart license?! Can anybody help please?
Thanks
Holger

Apex 4 - Flash Chart - How to open link in same page

Can you please help me on this.
Thanks in Advance.

APEX 3.0 - flash chart using 'Omit label interval'- missing lines in legen

Hi,
we are using APEX 3.0 on XE as development database.
Using the option "omit label interval" in the flash chart configuration, the legend will show the entries the same way as the x-axis.
For example:
setting omit label interval to 23 to get only one entry per day on the x-axis (we have one value for every hour of the day and want to display the chart on monthly base). My chart containing 2 series will show only the legend entry for the first serie.
How can I display the second one ?
Greetings
Marco

Marco,
Unfortunately, that's a bug in APEX 3.0. The 3.0.1 patch set will include a fix for it.
