SVG Chart Cluster Bar Vertical messes up the Series

Hello friends
I am trying to do a Risk chart which is No of Items by Risk Level By Department
So I have a set of series that are set up as follows
select null link, department_name Department, count(risk_id) from ECM_RISK where risk_level = 6 group by DEPARTMENT_NAME
select null link, department_name Department, count(risk_id) from ECM_RISK where risk_level = 5 group by DEPARTMENT_NAME
select null link, department_name Department, count(risk_id) from ECM_RISK where risk_level = 4 group by DEPARTMENT_NAME
select null link, department_name Department, count(risk_id) from ECM_RISK where risk_level = 3 group by DEPARTMENT_NAME
etc.
Now what happens is that if there are no records for that department in any of the risk levels, the department name is not getting pickedup. As also the scale of the graph is wrong and the no of risk items depicted.
The individual query on SQL runs correctly , but the graph is not
Please help with your ideas
Thanks

Charts: Gap between Vertical Axis and the chart area

Friends,
I have a really wierd issue and I am sure I am doing
something wrong.
I am trying to align 2 charts that are placed vertically. I
want to align the left vertical axis and the gridlines within them.
Aligning the left vertical axis is easy and done but aligning the
grids is becoming challenging and I have already spent a few hours
on this problem.
Here is a wrong chart image ...
Wrong
chart image
The line of the LineChart (in the top chart) is touching the
left and right edges where as the bottom chart bars do not touch
the left/right edges. Due to this the gridlines are not aligned.
I had managed to solve this problem but I am not sure what
part of the code solved the problem. Here is the right chart image:
Right
chart image
In this chart, the line of the linechart (in the top chart)
is not touching the left and right boundary hence the gridlines are
alignd with each other.
I wonder what property of the chart controls the series
touching the left/right vertical axis or boundary. Your help is
appreciated.
Thanks

here is some more information ...
I started changing some of the properties of the chart which
I mentioned is a RIGHT CHART and this is what I learnt ...
It was a CartesianChart hence it was creating the gap
between the left/right vertical axis and the actual chart area
(refer to the right chart image).
I changed it to a LineChart and it started behaving like the
chart in the WRONG CHART image.
Is there a solution to this problem?

Maximum Rows for series in Charts (Cluster Bar Charts)

Question
Is there a way to dynamically define the "Maximum Rows" value for all the series in a cluster bar chart? I tried putting "&item_name." into the "Maximum Rows" field for a series, but get an Application Builder error indicating that the value should be numeric. I would like to set the "Maximum Rows" for all the series in a chart "on the fly".
Details
I have one horizontal cluster bar chart with 4 series on my page that has a variable number of rows i.e. the number of bar clusters that I want plotted varies based on the user's criteria. For one set of data there may be 10 clusters. If the user changes the criteria, the chart could then have 20 clusters. I have the "Maximum Rows" field for all 4 series in the chart set to 31 rows.
The Problem
The chart with only 10 clusters is two thirds whitespace. The 10 clusters fills up the bottom third of the chart. The top two thirds of the chart is blank. The chart with 20 clusters fills up the chart with no whitespace. The chart with 40 clusters gets the top 10 clusters cut off and only displays the bottom 31 clusters.
Any Suggestions
If you have any suggestions how I can accomplish this, please post them. Currently I am not interested in going outside of HTML DB. I may end up doing that though to get a more dynamic charting tool.
Thanks,
Mike

Note 367711.1 deals with this issue. The contents of the note are the below:
At this time, this is not possible to dynamically set these charting attributes, however, an internal enhancement request has been created requesting that this functionality be incorporated into the product. The current plan is to incorporate this feature into 3.0 version of the product, however, this is just the current plan and can change depending on the complexity of the implementation.

Can't display the correct numeric characters in SVG charts with IE5.5 SP2

Hi all,
although I defined the following format model for the number in a SVG chart
FML999G999G999G999G990D00
I am still getting the dollar sign and the period, even if my current browser language preference is set to italian (IE 5.5 SP2).
Note that month names instead are correctly translated (in a region other than that containing the SVG chart).
On the other hand, this does not happen with Mozilla 1.7 which correctly shows the euro sign and the comma as decimal separator.
Bye,
Flavio

Flavio,
This is a known bug with the chart builder reading Internet Explorer's browser language setting.
You should be able to bypass this by editing the Application Attributes and setting the Primary Application Language to Italian and setting the Application Language to derive from the Primary Application Language instead of the browser setting.

Dynamic Query in SVG Chart

Hi,
I have SVG Chart, Chart Type: Cluster Bar, Vertical. I have 4 Chart Series. First:
SELECT null link, X.MESIC
FROM [email protected]
WHERE ..........
I have given dynamic Chart Series Query:
'SELECT null link, X.MESIC
FROM '||adm||'.[email protected]
WHERE .........."
but Apex write error:
1 error has occurred
Failed to parse SQL query
Please help as in what am i missing?

You can either use a SQL query or a function returning SQL query as the source of your chart. Just adding some quotes to a query however doesn't make it dynamic nor a function. Try something like this:
begin
return 'select null, ename, sal from emp';
end;
Edit your existing chart source, and check "Save query without validation", so that APEX doesn't attempt to parse and validate the query when saving.
Hope this helps,
Marc

Foreign characters in SVG charts

Hi!
I am again having some trouble using SVG charts.
I want to label the values with descriptions from a table. These descriptions often contain german umlauts. The resulting graph (line type) shows no values at all and the labels show a square character for each "Ã¤" (Ã¤) and after an occurrence of "Ã¶" (Ã¶) all of them are cut off completely. (I guess that's why I don't see any values at all - the parser stops when encountering an unknown character.)
A quick look at the XML specification tells me, XML processors must accept UTF-8 or UTF-16 characters. IOW, umlauts should not be a problem when encoded correctly. But I don't know whether the Adobe SVG Plugin I use adheres to that or not. Another possibility would be, that the font used to render the graphics does not contain umlauts. But that wouldn't explain why I don't see the values.
So, what encoding does HTML DB use for XML output? Does anyone know who is to blame? Of course, it could be me too.
My workaround will probably be a view which replaces the umlauts with ASCII transcriptions. But I would find that pretty ugly because I already have a bunch of these. Any other possibilities to circumvent this problem are welcome.
J.

Additional info:
the XML file I can copy from the browser shows a translation of the umlauts like this:
Getr & # x 4 B A B ;e (spaces only for escaping; formerly GetrÃ¤nke)
When an "Ã¶ occurs, the remaining XML tags are being closed and the file ends:
K</text></g></svg> (should have been KÃ¶rperpflege)
So with my smattering of XML I guess the output of HTML DB is wrong and I have to replace umlauts 'manually'. Please drop a line if you can confirm or confute that.

SVG CHart error ORA-20001 with Stacked Bar Chart HTML DB 1.6.0.00.87

Hi,
during I put a How-To into execution (How To Create a Stacked Bar Chart) I'll get the following error code:
SVG Chart error:ORA-20001:line_Chart error:ORA-20001:
get_data error:ORA-20001:Parse error:ORA009
(see http://www.oracle.com/technology/products/database/htmldb/howtos/index.html)
This Situation occurs when i add a second series to the
chart. The first series works fine. I've used the following SQL-Statement:
select null l, sales_month, revenue from (select to_char(o.order_timestamp,'Mon YYYY') sales_month, sum(oi.quantity * oi.unit_price) revenue, to_date(to_char(o.order_timestamp,'Mon YYYY'),'Mon YYYY') sales_month_order from DEMO_PRODUCT_INFO p, DEMO_ORDER_ITEMS oi, DEMO_ORDERS o where o.order_timestamp <= (trunc(sysdate,'MON')-1)and o.order_timestamp > (trunc(sysdate-365,'MON'))and o.order_id = oi.order_id and oi.product_id = p.product_id and p.category = 'Audio' group by to_char(o.order_timestamp,'Mon YYYY') order by sales_month_order);
Please help.

Well,
I've just been struggling for a couple of hours with a cluster bar chart giving the same problem.
The problem is definitely with "ORDER BY".
I guess the graphing chart is taking the sql query as a string and then does some other manipulation on it which ends abnormally when you include the order by clause.
I presume that if you embed the query in a
SELECT * FROM (<actual query with order by>)
it might mitigate the problem.

Horizontal Cluster bar chart

I am tasked by my PHB to produce a horizontally-stacked bar chart, the horizontal axis is for simple numbers of events, the bars are types of events. It should also have a negative 'reflection' (see drawing below) There is no Z axis. I have successfully generated this as a vertical stacked bar chart (very simple) and I think a simple rotate 90 degrees right would do it, but I can't find one.
It should look like this, ignoring the dashes:
######## ######## Event 1, Value 8
----###### ###### Event 2, Value 6, etc
Any ideas or workarounds welcome!

EDIT Post to refer to a horizontal cluster bar chart which is what I really want
Edited by: mansfields on Dec 3, 2008 2:44 PM

The horizontal equivalent of the vertical stacked bar would be a horizontal stacked bar, which is there on the menu for me to see. As said in my previous post 'what I am after is the horizontal equivalent of the vertical cluster bar'
To repeat what my requirement is, I have a group of sales people who have five measures each against them, and I can already graph them thus:
6 5 4 3 3
but I want to graph them this way, like 90 degrees rotated to the right:
6 ######
5 #####
4 ####
3 ###
3 ###
I think this would be called a horizontal cluster chart, and there is no option on the list that is called that.
Hope this makes it clearer, and thank you very much for your time and effort so far.
keith
EDIT
From the online books section - "you can only display clustered bar charts in vertical format". That sorts that out then.

Cluster Bar charts

HI,
I have a cluster bar chart that runs well with one query. The problem occurs when you add more than one series. I get an SVG Chart error ORA-20001 The only differenece is that the second and third series would have a distinct[b] resolution_type. Has someone run across this issue? I have pasted my query below:
SELECT NULL l
, MON
, MAX(resolution_type) resolution_type
FROM ( SELECT TO_CHAR(stat_date,'MM/YY') mon
, NVL(COUNT(status), 0) resolution_type
FROM ht_issues
WHERE category = 'Help Desk Issue'
AND resolution_type = 'Functional'
and trunc(stat_date) between to_date(:P14_RPT_DATE, 'dd-mon-yy') - 27 and to_date(:P14_RPT_DATE, 'dd-mon-yy')
GROUP BY TO_CHAR(stat_date,'MM/YY')
UNION ALL
SELECT DISTINCT TO_CHAR(stat_date,'MM/YY') mon
, TO_NUMBER(NULL) resolution_type
FROM ht_issues
GROUP BY mon
Any help would be appreciated,
Thanks,
Wally

The SELECT statement you have is still only defining one series. You do not use UNION ALL to add a second series to a cluster bar chart. Use the "Add Series" button in the "Chart Series" to add your "SELECT DISTINCT TO_CHAR(stat_date,'MM/YY') mon , TO_NUMBER(NULL) resolution_type FROM ht_issues" query. Each series needs to be defined separately with its own SELECT statement.

Excessive whitespace apex svg cluster bar graph

Hi,
I've created a cluster bar graph which works fine except that it only fills half the space in the region, the rest is whitespace. If I expand the chart width the region increases size and the proportion of display to whitespace is still the same, about 50%. I'm pretty inexperienced with HTML, so don't be afraid of oversimplifying.
Any ideas on what to do?
Cheers

SVG chart and region on the same page

Hello,
I would like to know if it's possible to create an svg chart and and only refresh a region in the same page.
If it's possible, where I can find how to do this.
If I call an other page my data is ok. But When I refresh the same page my data is not good.
Thanks
Eric

Go to Dropdown web item properties and choose your report and use Before Command and use OPEN_CHART_DIALOG. You may try with After Command also.

Help need in Stacked bar vertical - No data found message

I am using Stacked bar vertical with the 3 series. The problem is if any one of the series returns zero rows for the query it displays the No data found message for all the series and blank graph is there on screen with just x and y axi with the name.
The result i want is if any series in the graph returns zero row for the query it should executed the other series and show the graph accordingly for the series fetch the data.
all these queries are returning the data when run on database instead of one.
Can anyone help me for this?

Hello Sunil,
you may find some info here:
Document on Multiple Series SVG Line Chart
Generally speaking, if you want your queries to return "dense" data, you must ensure that a zero (Y value) is returned against each X value. If your queries return no rows, it means you must "artificially" create values, probably rewriting the queries with an outer join to a table returning the desired X values and using NVL function to replace null (Y) values with zeros.
Also, be careful with the order of X values, it really matters, otherwise you'll get skewed charts!
Bye,
Flavio
