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.

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.

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.

Decrease the size of a series marker on a bar chart

I am trying to decrease the size of a square series marker on a bar chart in crystal reports.
Usually this can be achieved through the 'appearance' tab in the 'chart options' menu.
However as I have changed one of the series(bar) on the graph into a line, this no longer seems possible.
Is there a way around this?
Thanks

Hi Natalie
In order to decrease the size of a square series marker after changing the series into line, you can use Format Series Marker -> Border -> Thickness.
Hope this helps!

Line chart and Bar chart

I have been assigned task to build the line chart and bar chart in Java. Is there any Java package that supports to draw such charts?

How t sort data in chart view (bar chart)

Hello,
I have a table view and a chart view in my visual composer model.
the data in table view are sort A,B, C ---Z
but in my chart views (bar charts) the listing begins with Z,Y,X,.....A
(same data service/ BI-Query)
How can I sort my listing in bar chart so, that the listing begins with A,B,C
Thanks,
best regards
thomas

Connect the OUT port of dataservice to IN port of SORT operator. This SORT operator is available in Compose > Operators.Configure the SORT operator , select the column on which you want to sort. Then the output of SORT operator should be connected to the IN port of CHART.
This should give you the desired result.

Hide Textmarker for one series item on stacked bar chart

Numbers Charts: Stacked bar chart with two sets of data

Hi....newbie with first post
I'm trying to create a stacked bar chart with two lots of comparative data.
So, there is Basic + Overtime for April 2010 as one stack (ie the basic is one colour, stacked on top is the overtime in a different colour)
Basic + Overtime for April 2011 next to it.
I can get April figures next to one another as four separate columns (2 x basic, 2 x overtime), or I can get all four figures in a single stack, but I can't to two columns (one for each year) of basic and overtime.
Any ideas?

UK,
What you are trying to do will require that you interleave the two sets of two-series data into one longer two-set series, and then plot just the one pair of series. Clear as mud?
What I'm saying is that you have to fake out the program into thinking that you have just two sets, not four.
You will have one series that has, for instance Apr 2010 Basic, Apr 2011 Basic, May, 2010 Basic, May 2011 Basic, etc.. This other series in that chart will have Apr 2010 Overtime, Apr 2011 Overtime, May 2010 Overtime, May 2011 Overtime, etc.
The bad thing here (I'll anticipate your first complaint) is that 2010 and 2011 data will have the same color for Basic and another color will be assigned for both 2010 Overtime and 2011 Overtime.
To get separate color sets for 2010 and 2011 data pairs, you will have to create two charts and overlay them. Both charts would be built in the alternating year format described above, but in one chart all the 2010 data would be blank and in the other chart all the 2011 data would be blank, leaving spaces in the chart for the data from the other chart to nest in.

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 = 5 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

thanks for all in advance.

I dont see any control from reporting tool on Text file content, since before Text file it was as expected. You need to go for other settings from Text I guess.
If helps pls mark
PS: I was not clear about your reporting tool (obiee or anything else) but comments are same.

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.

Help with stacked bar chart

Hello,
I'm looking for help regarding horizontal stacked bar chart. Typically for stacked bars Publisher seems to want data for each stacks per row, but my data looks like this:
<DATA>
<ROW>
<TYPE>Type 1</TYPE>
<CLASS>A</CLASS>
<TOTAL>10</TOTAL>
</ROW>
<ROW>
<TYPE>Type 2</TYPE>
<CLASS>B</CLASS>
<TOTAL>10</TOTAL>
</ROW>
<ROW>
<TYPE>Type 1</TYPE>
<CLASS>B</CLASS>
<TOTAL>20</TOTAL>
</ROW>
<ROW>
<TYPE>Type 2</TYPE>
<CLASS>A</CLASS>
<TOTAL>10</TOTAL>
</ROW>
<TYPE>Type 3</TYPE>
<CLASS>A</CLASS>
<TOTAL>40</TOTAL>
</ROW>
</DATA>
So each bar would be the TYPE element, and each stack within the bar would be the CLASS element.
Here is a very crude drawing of what I would want the chart to look like: http://i.imgur.com/3gEdEQ5.png
How can I achieve this? Thanks in advance.

Jody,
I'm sorry that I missed that you didn't want an overlay solution. You wrote it plainly, I just didn't read carefully.
This is as close as I could come to how I now read your request:
Here I have charted your Actual and a column of zeros that I have called the Goal Reference. The last column contains the goal values and I have used them as Positive Custom Error Bars for the Goal Reference series. I'm not thrilled with the look, but unless I know for sure that I'm on the right track, I'll leave it there for now. The width difference between the goal and the actual can be adjusted.
