Openoffice spreadsheet draw combination charts programatically

hi all,
we need to develop a project that is an extension in OO so that it could display a mutitype chart we have drawn in Excel.
Essentially, we have a combination chart consists of a candle stick chart and a line chart appearing together. OO could not display it!
(see http://qa.openoffice.org/issues/show_bug.cgi?id=27363).
We have research the problem for a while and figure that the easiest way is to develop an extension in Java using the Netbean Integration tool. Probably, adding a new chart type so that it is matched to the excel version. In chart2, it appears that they have changed the structure to a MVC model and under the diagram service, a coordinate system could have a list of charttype. So it appears that it is possible to draw a chart with different charttype on it even without the extension. However, we have not tried the chart2 API as we can't find a working example and SUN is not very helpful either and they discourage us to use chart2.
(see http://graphics.openoffice.org/chart/chart2codestructure.html)
can you give us advise how to approach this problem ?
documentation resources , code snippets to call chart2 api from java code and any other helpful suggestion will be very welcomed.
thanks.

ok let me put it simply :
com:sun:star:chart2 is not written in java, it is all written in C++ with those horrible IDL files which I don�t want to know about.
However, i do think UNO make it possible to be used in a java environment.
i searched the OOo website and also the web for an example snippet of a java program that calls com:sun:star:chart2 ; but i didn't found anything.
it would be great if SUN engineers in this forum show me an example of how to use the OOo chart2 API in a java program.
thanks.

Combined Chart with Jfreechart

I am using jfreechart-0.9.3 for drawing 4 charts on the same plot. I want to have two of them horizontally and two vertically next to eachother. When I tried to imitate the code of Demo combined charts by jfreechart (which only draws two charts next to eachother horizontally), I can't do that vertically. Because there is no
com.jrefinery.chart.HorizontalXYBarRenderer and com.jrefinery.chart.VerticalDateAxis classes. How can I make it vertically? Is there any other classes which could be usefull in jfreechart?
The code of two horizontal charts looks like this:

I don't believe it supports putting them vertically and horizontally... only one way or the other. ...
Although, 0.9.3 is pretty old... what about a newer version... I haven't played with those charts in about 9 months, so my info is a little out of date. Problem is, after 0.9.6 (I think) they changed a lot of the packages around so a lot needs to change.

Dynamic Combination Chart

I am using Report Builder 10.1.2.0.2 to generate an RDF that will be deployed to the application server via the rwservlet.
I need to create multiple combination charts (about 20). Is it possible to create the charts dynamically based on a query (repeating frame style)? Or do I have to create each graph manually (fixed)?
Any help would be greatly appreciated.
Thank you,
Roger

Hi,
Can you please mention it clearly when exactly the data changes in your chart.
In which properties you have bined the excel cell. Test it manually by changing value in the excel binded cell and check wheather the changes are happening or not.
Take and spreadsheet and bind it to MAX fucntion cell and Chart Array values and record the changes during run time.
It may help you to record the changes happening during runtime.
Through this you may find a solution for your problem,
If still the problem pertains please provide the Xcelsius SP version and fix pack
To get such details
In Xcelsius you can go to Help menu

Not able to show data in combination chart

Hi Experts,
I am new to BO Design studio and I am facing some issues in beginning itself. My issue is, I have 12 months data for some KPI's and I need to show two KPI's values in a single chart(Combination or Dual axis).
In Initial view I have selected needed KPI's and measures
once inserted chart, in data selection I have selected only those two KPI's which i want to show in chart but when i select 2nd KPI's measures I am getting following error.
Am I doing in right way? Is there any other way to show two KPI's measures in combination chart?
Please help
Regards,
Mathivanan.M

What type of object is Vendor_KPI in your screen shot? Is it a measure?
Separately it looks like some fixes are planned for Design Studio 1.3, planned for end of May (roughly) - this is what we heard last week. See http://service.sap.com/sap/support/notes/1979823

Plotting a combination chart with a combo box for selection

Hi:
I am a newbie using xcelcius and I need help on the following:-
I need to create a combination chart that plots 3 years data by month, and I need a combo box selection at the top that allows me to select user display for each difference region. I manage to create one that plots only 2008 data with a combo-box selection, but I have no idea how to do it for a combi chart in xcelcius. Any advise?

Hi Ning,
I assume your data are like this:
Region             Year     Jan     Feb     Mar
APJ             2006     $234.45     $310.34     $321.54
APJ             2007     $314.35     $319.12     $256.89
APJ             2008     $425.54     $354.34     $285.73
North Asia     2006     $534.64     $642.35     $484.64
North Asia     2007     $631.74     $654.13     $754.34
North Asia     2008     $754.31     $423.65     $634.32
South East Asia     2006     $536.42     $576.35     $525.42
South East Asia     2007     $426.78     $876.43     $643.75
South East Asia     2008     $634.87     $425.77     $732.43
If this, you can set the insertion type of combo box is "Filtered Rows", see steps:
1) For Combo Box, bind General > Labels to the Region column.
2) Set General > Data Insertion > Insertion Type is "Filtered Rows" (you can refer to following flash to see how "Filtered Rows" works).
3) Set its Source Data are Year, Jan, Feb, ... columns and Destination to blank cells.
4) Bind Chart to the destination data.
Now when you select APJ from Combo Box, it will insert all the rows of APJ data to the desitination cells which will be displayed in Chart.
Hope this can help!

Problem with logarithmic scale in combination chart

Hi Experts,
I have a combination chart where in primary axis i am showing column chart and in the secondary axis, i am showing line chart. Now as the range of values used in the column chart is big, I have to use logarithmic scale in primary axis. But if i do so, the line chart is also being affected. The markers for negetive values in the line chart plotted in secondary axis disappears if I apply logarithmic scale in primary axis.
Is it a bug ?
I am using Xcelsius 2008 SP3.
Thanks and Regards

Hi:
Yes, I also noticed this problem, seems when you set primary axis as "Logarithmic", the secondary axis with negative value "<0" will be ignored as "0". I think it should be an issue.
A quick work around here is, swith your primary axis and your secondary axis, when you set seconary axis as "Logarithmic", the negative values in primary axis will not be ignored.
Hope it helps.

Combination Chart: How to link auto-scaling of both Y-Axis?

I have a combination chart showing a couple bars and a couple lines. The bars use the left Y-Axis and the lines correspond to the right Y-Axis. Although they are based off seperate Y-Axis', the information is still related to each other.
Under my combination chart i have a slider which increases/decreases a 3rd set of red bars and it can push them so high that the Y-Axis will auto-scale itself, which is great. But what happens is the secondary Y-Axis will not also re-scale to go wth the primary Y-Axis. I have 2 screenshots to help demonstrate things a bit better. So although the information is still technically correct, it is visibly incorrect. Is there a way to link these 2 Axis together so it knows the max on the left Y-Axis before touching the slider is related to the max on the right Y-Axis? So if the primary y-axis grows, the secondary needs to as well?
PICTURES
The slider adjusts the red bars and i put them all the way up just before the point where it re-scales the primary y-axis:
http://img38.imageshack.us/img38/7853/beforel.jpg
Now i cranked the slider all the way up and the primary y-axis rescaled itself but the bars still look the exact same in relation to that blue line running across them. The 2 lines on the graph that use the right y-axis should have dropped lower at the same time the blue/yellow bars did:
http://img602.imageshack.us/img602/7996/afters.jpg
Thanks for the help, I appreciate it!

Hi Scott,
You can control the scaling on the secondary Y axis. Find the maximum of the data for line as well as the column chart (here you can take help of MAX() excel formula) then take the maximum value out of the result and that cell storing data from slider. In this way we can find out the largest data among all. Use that data as the maximum limit for primary as well as for secondary axis,
Go to the Behavior tab of the chart > primary scale > maximum limit > elect the cell containing the calculated maximum value.
Repeat the same steps for secondary axis also. Now the change in one series will have uniform effect on both the axis.

Change color palette of combination chart

Hello everyone,
I am experiencing a problem when trying to change to color palette of a combination chart.
According to the api there should be a method setColorPalette(aColorPalette) and a property colorPalette;
(JsDoc Report - SAP UI development Toolkit for HTML5 - API Reference - sap.viz.ui5.types.Combination)
when I try to call this method I receive the following error:
TypeError: Object [object Object] has no method 'setColorPalette'
I introduced the combination chart before by calling jQuery.sap.require("sap.viz.ui5.types.Combination"); outside of the controller;
I also tried to add the porperty colorPalette in xml, but it seems to be ignored.
Has anyone an idea on what the reason could be?
Best regards,
Benedikt

Hi Benedikt,
you can find below working code of changing color palette of chart.
This is based on pie chart but accordingly you can use for combination chart.

I´m trying to make a Pareto Diagram with a Combination Chart, but I need a secondary Y axis for my cumulative frecuency. Is that possible???
Thanks in advance.

Hi Jessica,
It is possible to do Pareto Diagram with combination chart.Do like this take one measure on Primary Axis and select second measure and enable the secondary axis and map the values.

Stacked Bar Combination Chart in Reports

Afternoon
I have a requirement for a chart that is a stacked bar chart chart with the addition of a line chart.
The combination chart allows Bars and Lines, but can't see how to change this to a stacked bar. Is there a setting I can change in the XML?
Report Builder 10.1.2.0.2
Any ideas?
Regards
Richard

Solved my own problem.
Add graphType="BAR_VERT_STACK" to the "Graph version..." as below:
<Graph version="3.2.0.22" markerDisplayed="false" markerShapeInLegend="false" graphType="BAR_VERT_STACK">
Also ensure the bar series are set to "MT_BAR" and line is set to MT_MARKER

Stacked Bar and combination chart

Hi Guys,
Does anyone know if it is possible to do a combination chart with a stacked bar chart and line chart.
Thank you

Jess_C,
There is no predefined chart to solve ur purpose. Try to sync both the charts and use Manul scaling.
Thanks.

Combination Chart using APEX

Is it possible to develop a combination chart (say a stacked bar chart + line chart) on the same chart using APEX? I have a requirement where standard deviation needs to be on line chart connecting through bars.
Thanks
R

Hello,
Have a look here: http://anychart.apex-evangelists.com/pls/apex/f?p=755:10:0::NO:::
You find the source at the bottom of the page.
If you change your column alias to something like: "{name:Minimum;type:Line}" it will render that value as a line even if you have the main type as a column chart.

Possibility of creating combination chart Barchart/Line graph within OBIEE

Hi
Is it possible to create a combination chart within OBIEE as can be done in Excel by changing the chart type on one of the individual series - ie graph multiple series of data as a combination of Barchart & Line series?
Any info appreciated
Thanks & Regards
K

The charting can be as dynamic as you like if you willing to pre-configure the required options.
Simply create as many charts as you want from one request, and use a view selector to allow the user to switch between them.
You can use level based measures and any else you want as seperate columns (all in same request) then chart them accordingly.
Hope this helps
