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

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

Bug: Flash charts and "Region Header" property

Hi,
it looks like that the a Flash Chart region doesn't renders the text of the "Region Header" property in the header of the region, instead it is rendered in the footer of the region.
See http://apex.oracle.com/pls/otn/f?p=2672:1 for an example.
For SVG Charts it works.

Hi Marco,
thanks for the tip with the DIV and the BR. Both work.
Maybe it would be a good idea to add the DIV by default, otherwise people could think that the region header/footer function is broken.

Flash chart fails through proxy

I've had to setup one of my applications recently to run through an Apache proxy to reach my Oracle HTTP server. It's setup as a 'reverse proxy' and works fantastic for everything - except my flash charts.
Does anyone have any idea why this is failing and how I might fix this? I've noticed that there is a parameter in the chart XML
<param name="allowScriptAccess" value="sameDomain">I've Googled this and found very little that tells me exactly what this parameter is controlling, and whether it might be causing this problem. Anyone have any ideas?
Earl

Hi Earl,
The 'problem' is that the #HOST# substitution string in the Region Source for the Flash chart, will be using the fully qualified address for your internal machine rather than picking up the settings (particularly the port) from the requested server.
In other words, if you have -
Publically Accessible Server - running on port 80
Internal machine - running on port 7780 (for example)
then the #HOST# substitution would use port 7780 (which would not be routable from the public facing site).
There are a couple of workarounds, including passing through the host and port through to your mod_plsql environment, e.g. adding this to your DAD -
PlsqlCGIEnvironmentList HTTP_HOST=<public hostname>:<public_port>for example -
PlsqlCGIEnvironmentList HTTP_HOST=foo.com:80This might, of course bring it's own problems if you rely on using HTTP_HOST internally in your processing, but as you can imagine there's ways to work around that too (which I'll share if you need to, otherwise I'd just be typing it for no reason!).
As another workaround, you can edit the region source for your Flash charts and replace the #HOST# string with a 'correct' hard-coded value appropriate for your environment, but long term this isn't a great solution.
Hope this helps,
John.

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,
4 max(x.value) max_val,
5 min(x.minutes_diff) min_diff,
6 (max(x.value) - min(x.value)) * 24 * 60 time_span,
7 (max(x.value) - min(x.value)) * 24 * 60 / min(x.minutes_diff) slices
8 from (select t.value,
9 lag(t.value) over (order by t.value) previous_value,
10 (t.value - lag(t.value) over (order by t.value)) * 24 * 60 minutes_diff
11 from test t
12 ) x
13 ) y
14 connect by level <= y.slices + 1;
VAL
09:03
09:33
10:03
10:33
11:03
11:33
12:03
7 rows selected.OK, now we have 30 minutes between every time value.
Step 4: join newly generated time values with the original table. Use OUTER JOIN; missing labels will be 0 (zero):
SQL> select
2 null link,
3 to_char(z.val, 'hh24:mi') new_value,
4 nvl(t1.label, 0) new_label
5 from (select y.min_val + (level - 1) * y.min_diff / (24 * 60) val
6 from (select
7 min(x.value) min_val,
8 max(x.value) max_val,
9 min(x.minutes_diff) min_diff,
10 (max(x.value) - min(x.value)) * 24 * 60 time_span,
11 (max(x.value) - min(x.value)) * 24 * 60 / min(x.minutes_diff) slices
12 from (select t.value,
13 lag(t.value) over (order by t.value) previous_value,
14 (t.value - lag(t.value) over (order by t.value)) * 24 * 60 minutes_diff
15 from test t
16 ) x
17 ) y
18 connect by level <= y.slices + 1
19 ) z,
20 test t1
21 where t1.value (+) = z.val
22 order by z.val;
L NEW_V NEW_LABEL
09:03 0
09:33 0
10:03 1
10:33 0
11:03 2
11:33 1
12:03 0
7 rows selected.Cool, so we have them all. Now, go to Apex and create a chart using a query from step #4.
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).

Passing values to iframed page with flash chart.

Hi,
I'm trying to dynamically generate a series of charts within a sql report.
In my report i make several calls to a page with a (flash) chart and i pass some values to this page/chart by setting page items through the source url of the iframe.
The problem is that all the iframed instances of the page in my report display the same data although each iframe sets specific page item values through its source url.
(only the page item values that were set by the last call to the page are being used by all the other chart instances)
So why does this happen?
Are the iframed charts rendered to slow?
Is this a flash problem?
Should i call each iframe within a seperate session?
And does anyone know how to correctly pass values to the iframed page / chart so each instance of the page/chart displays the correct data?
Thanks
Niels

Solved my problem by leaving the SESSION part blank in the src url of the iframe.
Apex creates a new session for every iframe now, the page items values are not overwritten and the data is displayed correctly.

Flash Chart

Hi Everyone,
I am in the process of making a few flash charts and i have a few questions I hope someone can answer for me.
1) The chart series colours seem to be pre determined, (blue, purple, v.light pink, turquoise, .......) is there any way of changing the colour of these?
2) The labels inside the chart legend get cut off. For Example, "Total Forecast Data" gets cut down to "Total Forecast Da". Is there any way of wrapping the labels in the legend or simple making the legend bigger?
Thanks in Advance
-N.S.N.O.

Hello,
You can adapt the xml of the chart in APEX. If you go to the settings of the chart and at the bottom put Custom XML to Yes.
You find the xml reference here: http://3.anychart.com/products/docs/anychart/index.htm
The part you want to change :
<root>
<type>
<legend>
<values width='40'/>
</legend>

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,
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).

Flash Chart Bar Colors

We just came up on 3.0.1 from version 2.
Now I want to implement Flash charts and everything is working fine with the exception of the colors on bar charts. My customer wants colors different from the default.
How can I change the colors of the bars on the charts?
Bob

Bob,
Under the Chart Attributes, select Custom Color on Color Scheme and enter your desired color or select one via the Flashlight.

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.

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.

Serie's Name in Hints on 2D Flash Chart

Hello,
I would like to have the name of the series in the Hints of a chart, with name and Value.
I saw in the XML the following line:
<text><![CDATA[{NAME}, {VALUE}]]></text>
But I have no idea about what to add???
In advance, many thanks,
Fred

Hello Dimitri,
First, thanks for your answer.
I knwo as you confirm that I have to modiify the XML, but unfortunatly, I don't know what to write to be able to have the series's name in the Hint.
I tryed several thinks, but without good results: NAMES, {NAMES}, LEGEND, {LEGEND} in the line:
<hints auto_size="yes">
<text><![CDATA[{NAME}, {VALUE}]|http://forums.oracle.com/forums/]></text>
</hints>
In Fact, I would like to understand wich is the name of variable for the chart's name of Series.
Regards,
Fred

Off the shelf Flash chart with live update and slider?

Does anyone know of any good off the shelf Flash line chart
that has
1. Live AJAX-type update of data (without reloading entire
Flash chart)
2. Horizontal axis slider to be able to zoom in (like the
time slider on Google Finance)
I have been using
XML/SWF
chart chart but find that its live update is clunky.
Is doing a custom chart our best bet?
Thanks! Chirag

Hi,
it was a bug, corrected in patch 4.0.1 (bug 9868860), see http://www.oracle.com/technetwork/developer-tools/apex/application-express/401-patch-166923.html#BABJCAFA.
It's why it don't works with APEX 4.0.0.

Flash Chart Legend

I have built a 2D Line Flash chart with 6 series. My problem is that the legend shows the word "Value". Does anyone know how to make the legend display the series name instead.
Jeff

Varad,
Thank you for your reply but your answer does not appear to be the solution I need. This SQL statement below used in a SVG Chart yields a legend using the series name. The same SQL statemnet used in a Flash Chart yields "Value" as the series name. Why?
<pre>
SELECT NULL link,
to_char (minipay_detail_vw.event_dt, 'YYYY, MM') AS label,
sum (minipay_detail_vw.contract_pay_amt) AS value
FROM [email protected]
WHERE minipay_detail_vw.object_class_cd = '018'
AND to_char (minipay_detail_vw.event_dt, 'YYYYMM') <
to_char (sysdate, 'YYYYMM')
AND financial_organization_cd IN
('1650', '1655', '1660', '1665', '1670')
AND (:p337_fy = '%null%' OR minipay_detail_vw.fiscal_year = :p337_fy)
GROUP BY to_char (minipay_detail_vw.event_dt, 'YYYY, MM')
ORDER BY to_char (minipay_detail_vw.event_dt, 'YYYY, MM')
