Column Chart datalables issue.

Hi All,
I want to show the numeric value on the top of the column series.
I set the property labelPosition="outside" to column series.
It is displaying all the numeric value except 0 but I want to display as well.

Hi All
Alast I resolved the color issue...Due to exceptions it was not dispplaying..
I think even for negative value, we can set the MIN value with -ve value...
Hope resolved it on my own...

Help: Column Chart Display Issue

Post Author: ermiller
CA Forum: Xcelsius and Live Office
I have a chart that displays its data correctly 11 out of 12 times...and I can't seem to get the last one to work correctly. Here's the issue:
I have a table of data that looks like this:
REGION                                   GAIN                           LOSS                      NET
ALL                                           =SUM(BELOW)          =SUM(BELOW)       =SUM(BELOW)
REGION 1                                  10                               (1)                          9
REGION 2                                  20                               (2)                          18
REGION 3                                  30                               (7)                          23
REGION 4                                  40                               (0)                          40
I have a "Data Display" area that has the following formulas in it:
CRITERIA                                   GAIN                           LOSS                    NET
[USER INPUT]                           =VLOOKUP([USER INPUT],[TABLE ABOVE],0,[2,3,4 FOR EACH COLUMN])
If the user enters 'REGION 1', 'REGION 2', 'REGION 4, or 'REGION 4', the data is displayed in the column chart perfectly. However, if the user selects 'ALL', the process doesn't work and displays 0s in each of the columns above.
Does any one have any ideas on how to fix that issue or what could be causing it in the first place? I just noticed that the same thing occurs if I use a Grid component as well...even though Excel is processing the data accurately.
Thanks in advance,
Erik

Hi,
Without trying out your actual data, the first thing that comes to mind is that you aren't using all the options in VLOOKUP. I've discovered that Xcelsius requires all arguments even optional ones in many formulas but this isn't document). The last argument is TRUE (default) for the closest match, and FALSE for exact match. If the user can only enter from a set of values which are known to be in your lookup table, then either one will work but you should still specify this last argument.

Column chart labeling issues

Hi
Im trying put a label on top of each column chart bar vertically(Outside),
Im able to do it if it is a single column .
with "showlabelvertically" option but,
when i tried with multiple columns(column set) im not able to do it. do any one have a better idea in doing it.
Thanks in advance

hi rootsounds,
Thanks for responding, But i require is some thing like this app
http://blog.flexexamples.com/2008/01/23/displaying-the-labels-vertically-in-flex-columncha rt-control/
for column sets this doesnt work for some other examples that i worked too.

Multi-column chart issues

Hi,
I'm trying to make a 2d column chart of quiz entry results with multiple series (one per possible answer) but it's not working as intended. I have 5 series all with code like:
select null link, substr(question, 1, INSTR(question,' - ',1,1)), count(answer) from quizdata
where answer ='Strongly Disagree'
and :P13_DEP = emp_dep
and to_char(sysdate, 'YYYY') = to_char(ins_date, 'YYYY')
group by substr(question, 1, INSTR(question,' - ',1,1))Except with the answer being different (Agree, Strongly Agree~). However, when I load the page it only shows the results of the first series (Strongly Disagree, or if I delete that then Disagree)...anyone see what I'm doing wrong?
x-axis = question
y-axis = count (number of people to select that option this year)
There should be 5 columns per question.
Mike

For anyone who has a similar issue with multiple series being displayed the reason for my error was that I didn't specify a name for the value...since all of them were count(c) they clashed; making it count(c) "Disagree" etc made it display as intended.

Column Chart Issue

I have a column chart with multiple column series. The
vertical axis is of DateTimeAxis and formatted for hours. In one
instance the minimum y-value displayed on the axis is 3:00 hours.
Two column series with values of 5:20 and 8:03 are being displayed.
The third, whose value is 2:15, is not being displayed. I can,
however, mouse over the x axis where the column series should be
displayed and its dataTip pops up with the correct information,
most importantly the time 2:15. Any thoughts???

It seems like your veriticalAxis minimum value is above 2:15.
Why not set it lower and see if that helps.

Background Element Size issue in Column Chart

Hi All,
I am trying to add multiple chart to hbox dynamically with each chart having vbox as an background element and only first and last chart is having axis.
for example shown in below image three column chart are getting added out of which second chart dosn't contain either axis on left or right.
I am facing a problem in making background element of same size means there should not be size difference as shown below:
How can i make all the vboxes that i have used of same size ?
Thanks in advance.

Spacing is done based on the number of columns in the chart. It is better to use one chart and group the data accordingly. It is possible to add multiple axis for a chart

How to reset drill-down column-chart based on map-chart?

Hi guys,
I'm facing pritty common issue while designing one of my dashboards. Let me describe a little bit more:
1. I have some data extracted from BW using Query as WebService into my Xcelsius spreadsheet.
2. I have map-chart - regions for some country.
3. I have a drill-down column-chart, which displays data for a selected region.
At the beginning column-chart displays results for entire country (which, in fact, is not exactly drill-down). The issue I'm fasing is, that in case I select any region and the data is drilled-down into my column-chart, I have no option to show data for the entire county in the column-chart anymore (the only one way is to restart the report).
Are there any possible way to do this, or am I doing a design error while displaying data, which is not drilled-down, into a chart which is intended to display drill-down data only?
Any help would be highly appreciated.
Thanks in advance.

Ivaylo Mutafchiev,
I understand your problem now. So your column chart data which is coming from the QAAWS query should be having a prompt which is bound to some cell in excel. and your map might be passing the values for prompt isn't it? in your case the map might be passing a region.
All you need to do is put the prompt in the web service for region as a optional prompt. Now pull in a check box or a Push button(name it as reset or something.). while binding the data to the check box or push button (source data) bind it to a blank cell. when user clicks on it , it passes a blank vlaue to the region(this is ur input for region) which will inturn makes the prompt optional for the region web service. which should pull all the data for all the region.
The whole idea lies in somehow passing a blank cell to your web service whose region prompt is optional.
Thanks,
Karthik

Overlapping data when more data column chart SSRS

Hi guys,
In my ssrs report the column chart display is not good when more number of datas are viewed.How to overcum this issue
I searched more on this issue no good solution found.
I attached screenshot for this report,
any suggestions pls
Thanks,
R.B

Hi R.B,
I can reproduce the issue in my local environment. If there are more column data with adjacent values in the chart, the label will be overlapped due to the insufficient space. In this scenario, there are several properties you can use to try to get the labels
to fit better. Click the data point to open the Properties Windows, then go to the SmartLabels node.
Expand the "NoMoveDirections" node. This will give us a lot of directions that we can use to restrict the directions that the labels can move in. We can try to change directions to see if it helps.
Try to enlarge the chart size and use the method below to adjust the column size, it will free up more space to contain the label.
http://www.bidn.com/blogs/ChrisAlbrektson/bidn-blog/1832/ssrs-adjust-bar-chart-width
If we want to remove the black arrow, we can refer to the following thread:
http://social.technet.microsoft.com/Forums/en-US/e3019086-4f72-4898-ba86-2e7c97c8fae4/ssrs-series-lable-overlaping-issue?forum=sqlreportingservices
Alternatively, we can use Tooltip property to instead of actually displaying. Type the same expression with Value field in the Tooltip property.
Hope this helps.

Null object reference error in Axis Renderer in Case of Stacked Column Chart

We have invested so much effort and done lots of googling and also followed the work around given on https://bugs.adobe.com/jira/browse/FLEXDMV-2275 but till now, we didn't get any solution.

I solved the issue by getting rid of the creationCompleteHandler event handlers for the KPI charts. But, since I am just days into flex development, I would be indebted if someone could explain to me why that was creating problems.

Missing column in the column chart - is it the selector's fault?

Hi folks, thanks for bearing with me here:
I'm working on fixing some issues on a dashboard that someone else has set up (and there's no way for me to reach that person). One of those issues is that one of the columns in a column chart does not display on the dashboard when exported. The column chart is pulling the data from the correct cells, so the problem doesn't seem to stem from there.
I thought I got to the bottom of it when going over the scorecard. The range used for its source data cuts off before it reaches the data for the column in the chart that doesn't show up in the exported dashboard. However, when I adjust the range for the source data the resulting exported dashboard turns out an entirely blank column chart (even weirder, changing the source data back doesn't seem to fix this; I had to simply start back from my prior save state to reverse the blank chart).
So am I even on the right track here? And if not, any ideas on what's keeping that column from showing up?

Thanks Ameet, I tried out the table as you said and the data for the column and the vertical progress bar were missing from there as well.
It turns out I was correct about the scorecard's source data being to blame, and that adjusting it to include the fields in the spreadsheet that correspond to the missing graphics was the right course of action, the problem was something with my computer; I sent the file to another computer and adjusted the source data there, and it worked fine.
It puzzles me why the edits wouldn't take on my computer (after being exported). The only thing is maybe I need a newer version of Flash, but I have 9.0 r45 which should be enough.

Help we column chart display

HI,
I'm extending my dashboard to display printer information.
From the sample data below I want to display, each printers
job total count for each quarter.
Bottom access should show Q2-07,Q3-07-Q1-08 vertical axis
should show integers.
From the table below I want to display in each quarter a
column bar for each printer showing total jobs, and another column
in same quarter showing page total for each printer
AEc2880->JOBCOUNT:AEc2880->PAGECOUNT:CreativeFirey240->JOBCOUNT:CreativeFirey240->PAGECOUN T:
I can either get the grid to show quarters but only on
printer, or printers but only one quarter.

Each row is a printerName, JobCount, PageCount,Quarter,
printStartQuarter (first day of each quarter)
Requirements:
I need to display summaries in a column chart of Queue
(printer) usage. For each Queue summary I need to show total jobs
sent (printed) and total pages sent (printed) for a given period.
The one I'm dealing with here is quarterly view. With the
sample data above I want to show for each quarter total job, total
pages for AEc2880,CreativeFirey240 and AEIR5055
If I use the data has is, I only get one queue per quarter. I
need to have each queue its own column, twice. One for total jobs
and total pages. Then one row per quarter for it to work.
AEc2880_TJ - AEc2880_TP - CreativeFirey240_TJ -
CreativeFirey240_TP - AEIR5055_TJ - AEIR5055_TJ - Quater -
printStartQuarter.
Now for the big issue, the queues are dynamic. The test data
is from 3 queues only. There could be 1 to n number of queues and
not all quarters will be the same as queues get added and deleted.
This is how I approached this in AS Flex 2, I have flex 3 but
not installed yet, I can not find much info on the new grouping
classes to see if they will help.
Most examples are with the advanced data grid. There is also
very little information on charting bar the basics around.
My data comes in from PHP middle ware as JSON.
First think we need to do is pass the de-serialized array
into a function that finds all the unique queue names.
[Bindable]
private var groupQueueEvent:ArrayCollection;
private function setUpHandler(event:ResultEvent):void{
//get the raw JSON data and cast to String
var rawData:String = String(event.result);
//decode the data to ActionScript using the JSON API
//in this case, the JSON data is a serialize Array of
Objects.
var arr:Array = (JSON.decode(rawData) as Array);
//Send array for processing.
groupPrinters(arr);
//function that takes quartly events and finds unique queues
private function
populateComboYearArray(eventsArray:Array):Array {
var queueArrayHashMap : Object = new Object(); //create hass
array, used to make sure array unique
var queueArray : Array = new Array; //create arry to hold
queues
//now run through each row of passed data looking for queue
names
for (var i:int = 0; i < eventsArray.length; i++)
//check to see if this
queue is all ready in hash.
if (queueArrayHashMap[eventsArray .PrinterName] ==
undefined){
//it not in hash so add it
queueArrayHashMap[eventsArray
.PrinterName] = new Object();
// now add the queue array
queueArray.push(eventsArray .PrinterName);
return queueArray; //send back final array
private function groupPrinters(data:Array):void {
//create array to hold unique names
var printerNames:Array = new Array();
//process data and get unique queue names back
printerNames = populateComboYearArray(data);
var printGroup:Array = new Array;//hold the final array
var tempRowArray:Object;//used to build each row of new data
var pgCountColumnName:String;//used to build queue names for
page count
var jobCountColumnName:String;/used to build queue names for
job count
for (var printRow:int = 0; printRow < data.length; ) {
//run through each row of data
tempRowArray = new Array; //create a new row each time
// we will always want the Quarter and printStartQaurter in
every row so add now
tempRowArray.Quarter = data[printRow].Quarter;
tempRowArray.printStartQuarter =
data[printRow].printStartQuarter;
// now for the tricky bit, we need to process each queue
name
for (var i:int = 0; i < printerNames.length; i++) {
// we need to see if we have a queue name match not all
quarters will
// have the same queue names
if (printerNames
.PrinterName == data[printRow].PrinterName) {
//if match found add to our row
//make dynamic column name would like to use queue name but

Problem with loading column chart in flex2

Hi All,
I am facing a strange problem in designing a column chart. I have a page where i have two column charts. The data providr for both the charts is same. I have an xml with three categories of values, and each chart uses two of these with one of them being common and they are actually sorted based on one of those values. The problem here is that one chart shows proper values while the other (though shows proper values) it doesnt render it properly in the sense that the height of the columns and the value of that particular column are not consistent. What could be the issue????

It's necessary to discard the white spaces.
Set the ignoreWhite property to true.
document.ignoreWhite = true;

Add Total to Stacked Column Chart on the top and another important thing is the data are from SharePoint site

the same with the following description from another question:
"How can I display a total on top of each column on a stacked column chart (using
reporting services 2008)? If I use Data Labels I can display the
values for each part of the stack on a stacked column, but I want to be display the total.
For Example: If I have stacked column on chart with a value of 10 for the 1st stack, 20 for the 2nd stack,
and 20 again for the 3rd stack - I want to display 50 (the SUM total) as the data label on top of the entire column..."
and a solution for this would create a new column named SUM(category group), this can be done with data source from SQL server, but my data is from SharePoint site list. its query seems can't be changed which means I can't add a SUM column.
what should I do with this? Can anyone give me a hand?
thank you very much.

Hi sophiexu,
If we want to display a total for each column on the top of a stacked chart, we can use a matrix control to display the column total value to work around this issue.
The following thread about how to simulate chart legend is for your reference:

Hope this helps.
Thanks,
