"Scatter" Chart with Multiple Values per Date

APEX Gurus,
I need to plot a chart with multiple y-axis values along the x-axis.
Here's an example:
X-Axis (Date) Y-Axis (Number)
1-JAN-07 1
1-JAN-07 2
1-JAN-07 3
2-JAN-07 1
2-JAN-07 2
3-JAN-07 1
Right now, APEX displays the X-axis (Date) as separate values on the x-axis. But I want all three 1-JAN-07 values to line up vertically under x-axis. I am currently using a line chart for this. And it displays a "dot" for each value (depending on my max rows value).
Any insight would be much appreciated! And thanks in advance!
Susan

X-y Scatter chart with multiple data series

Hi,
How do I create an x-y scatter chart with more than 1 data series? For example:
Series 1
x__y
1__0
2__5
3__9
4__7
5__2
Series 2
x_____y
0.5___0
1.3___4.8
2.6___12.3
4.1___8.4
4.9___3.2
I can do this with 2 seperate graphs but I need them on the same graph.
Is there a limit on the number of series that can be placed on a single x-y scatter graph?
Many thanks.

Please re-post if this is still an issue or purchase a case and have a dedicated support engineer work with you directly:

Defining a scatter chart with multiple series

I am trying to create a scatter chart with two series. I am using CR8.5 and CR2008.
I am having difficulty with my data being presented correctly when I attempt to define the scatter chart. The data is temperature and weather use/sqft for two different years.
Year Period Temp Energy Use/sqft      Year Period Temp Energy Use/sqft
2012 1/2012 52 3.7172               2013 1/2013 52 3.1712
2012 2/2012 62 3.7015               2013 2/2013 57 3.1449
2012 3/2012 70 3.7937               2013 3/2013 63 3.2039
2012 4/2012 76 3.9882               2013 4/2013 71 3.4551
2012 5/2012 82 4.2213               2013 5/2013 81 3.9903
2012 6/2012 87 4.4875               2013 6/2013 85 4.3650
2012 7/2012 90 4.4727               2013 7/2013 87 4.2072
2012 8/2012 86 4.6154               2013 8/2013 87 4.2560
I would expect to see something similar to the attached images of an excel files scatter chart. When I defined the scatter chart in Crystal Report, I need to define a field for 'On change of', and 2 'Values to show'.
I understand that this would not show the expected scatter chart but I went this direction as the series is to be the year.
On change of:
- Year
Show values:
- Temp
- Energy Use/Sqft
Problem is the sum of both is being shown. I am trying to keep the series together by year and showing each record as retrieved from the database.
Thank you,
Jim

How can I label data points in a scatter chart with text strings?

Post Author: Bill B
CA Forum: Charts and Graphs
I need to create a Scatter Chart, with a text label for each data point instead of the xy coordinates. A legend will no longer be necessary.Also, I want to draw "cross-hair" lines on both the x and y axes centered on one particular data point.Any ideas?

CA Forum: Charts and Graphs
Hi
I have the same problem here, did you find any solutions.
Here we are ok if the dimension is displayed in the scatter instead of the measurements but the only options i founds was "Show data" and that option displays the values of the xy.
pls let me know if anybody found any solution for this problem

Convert a scatter graph with multiple data series into individual graphs

I am trying to convert a scatter graph with multiple data series into individual graphs, with the series having the same formatting as in the graph when all series are together.
Normally, if I delete any series, the color scheme for all the other series vanishes. I can then waste more time in having to re-adjust the color and shape of the series, but this is tedious. This, I do not want. Is there an automated way to do this?
Ideally, of course, all series would appear in little subsections in the space of the former one graph, all with individual axes, but I can't have all, so I'll settle with having several individual new graphs, each with just one series, and with the original
formatting.
Thx.

How about creating a copy of the chart, and then setting all series except one to be transparent (no line, no marker)? Repeat for each series.

How can I make a graphic (scatter chart) with 1 "y", but multiple "x" (to make a multiple linear regression)?

how can I make a graphic (scatter chart) with 1 "y", but multiple "x" (to make a multiple linear regression)?

Émilie,
The default for X-Y Charts is for X values not to be shared, so it's entirely possible for you to create X-Y pair sets that have common Y-values and independent X-values.
This answer assumes, as always, that I properly interpreted your problem statement. A linear fit line for each pair set should satisfy.

Scatter chart with two series?

I have a table showing my cat's weight each day. (He's on a much needed diet and it's important to make sure he's losing weight, but not more that about 1% per week, as I experiment with his diet.) I created a scatter chart with the date on the X axis and his weight on the Y axis, and I made a 7 day moving average trendline to show his progress with most of the random daily fluctuations evened out. So far so good.
I added a column to the chart with a function showing what his weight would be each day if it decreased 1% per week from the average of the previous week. I would like to add this column of data as a second series on the scatter chart so I can make sure he's not losing weight too fast. But I can find no way to do this.
I had no trouble showing both series on a line chart. But no luck with the scatter chart. I tried creating a new scatter chart using all three columns of data, and I tried dragging the third column of data to the original scatter chart.
Is it really possible that Numbers '09 cannot show two data series on a scatter chart? Or is there a way to do it?
Thanks for any assistance.
Bill

Hi Bill,
Maybe this will help. A Scatter Chart displays data pairs, such as a date and a weight. A single column of data would be only one half of the data-pair set. Select both the X and Y value columns for the second set and then add to the Scatter chart.

Line Chart with Multiple Series

Post Author: JayZee
CA Forum: Charts and Graphs
HI
I am trying to create a line chart with multiple series for trend analysis on CR XI but not having much luck, I thought it would be so simple to do!
My data is provided summarized on the server and is returned as 12 rows:
Month Year1 Year2 Year3 Year4 Year5January 100 80 75 90 120February 85 25 40 25 80etc for the rest of the months
My problem is that I can only get the chart to accept the values to display as a summary and not just as the data pulled back from the server. I have read an article on the support site for Crystal 6.0 but it doesn't seem to translate well into XI.
If necessary I could redesign the table to bring back un-summarized data but that is quite a big job.
Any help greatly appreciated.
Jay

In the chart expert, put Month in the 'On change of' box and put each year in the 'Show values' box. This puts the month on the x-axis and plots each year as a line.
Is that what you want?
I did this in CR 2008 using your data in an Excel sheet.

Is it currently possible to create a doughnut chart with multiple concentric circles in SSRS?

Is there currently any way to create a 'doughnut' chart with multiple concentric circles in an SSRS report (any version), without using 3rd party tools?
Something like this, perhaps?
(For that matter is it possible to create this using JavaScript? It's my understanding that this image was originally created in a web app using JavaScript. So far I've not been able to pin down the details. I've found hints that JavaScript
can be used in SSRS reports but so far no clear working examples.)

Hi B.Chernick,
According to your description, you want to create a create a doughnut chart with multiple concentric circles in your report. Right?
In Reporting Services, we only have doughnut chart with one concentric circle. All the category group is in that concentric circle. Though we can embed javascript injection in expression, it only give the css style to values or report
items which can change the looking. It can't change the structure of the report items itself. So your requirement can't be achieved current.
For your requirement, we suggest you provide Microsoft a feature request at
https://connect.microsoft.com/SQLServer
so that we may try to expand the product features based on your needs.
If you have any question, please feel free to ask.

Report script - using substitution variable with multiple values

Hi All,
Substitution variable with multiple values is not working correctly with Report scripts. Can you please let me know what is the syntax to assign multiple values to a sub variable using maxl:
alter database samp.samp set variable 'ExtractQuarter' 'Q1,Q2,Q3,Q4';
alter database Samp.Samp set variable 'ExtractQuarter' 'Q1:Q4';
I tried both of the above but they are errored out with the below error:
Error: 1001005 - Unknown Member [Q1:Q4] in Report.
my requirement is different for both Actual and forecast data extract so i would like to make use of this variable to extract whole year data for Forecast and current quarter data for Actual with out duplicating the report scripts for both processes.
Thanks,
PRaveen

Hi,
Please refer following thread,

OLAP on 11g and Materialised Views with Multiple Value-Based Hierarchies

Hello OLAPians
I am trying to setup Orable BIEE to report on an OLAP cube with pre-aggregated data. As OBIEE is not able to hook into the OLAP directly i have to create an SQL cubeview.
Currently i am on a 10g OLAP environment and am using the oracle sample SQL cubeview generator to create an SQLview of my cube.
The cube itself has multiple dimensions and these dimensions have multiple VALUE-based (ragged) hierarchies and dimension members can be shared across hierarchies also.
Initially i had a problem running the view generator plugin because there is a bug within it that does not finish if there are multiple value-based hierarchies present. I was able to get around this by manually editing the limitmap for the cubeview and manually creating the SQL view.
The question that i want to ask is how robust is the 11g materialised views with multiple value-based hierarchies and the sharing of dimension members across different hierarchies?
Has anyone successfully been able to create a cubeview and import it into OBIEE without the hassle of manually editing the limitmap?
A problem arises with the value-based setup whereby if the client creates a newer depth in the ragged hierarchy, i need to manually create the limitmap and the cube-view over again, and then re-map the BI Administration mappings.

The simple answer to your question,
how robust is the 11g materialised views with multiple value-based hierarchies...?is that materialized views are not supported on top of value-based hierarchies in 11g. The reason is that it is not possible to write a reasonable SQL statement that aggregates a fact over a value-based hierarchy. Such a SQL statement is necessary if we want to create a rewritable MV on top of the cube.
But I suspect this is not what you are really asking. If you are trying to set up OBIEE on top of the cube in 10g using the view generator, then you will probably want to use the "ET VIEWS" that are generated automatically in 11g. These are generated whether or not you enable materialized views on top of your cube. I am not aware of any issues with the generated value-based hierarchy view support in 11g. Members may be shared between value hierarchies and you will not need to generate or modify limit maps.

Snmp for oids with multiple values

Hi,
So if we have array of OIDs defined in the mib file (eg, 1.3.6.1.4.1.22.1.1, 1.3.6.1.4.1.22.1.2, 1.3.6.1.4.1.22.1.3 and so on each having different values). does anyone know how can we capture this using SNMP fetchlet?
or
do we need to specify each oid separately?
Thanks

Maybe I misunderstood lushhay here. I thought lushhay wanted to associate a key with multiple values. So one way is to have the value of the Hashtable key to be an ArrayList.
Hashtable table = new HashTable();
String key1 = "myKey";
String key2 = "myKey2";
Date value1 = (some date value);
Date value2 = (another date value);
Date value3 = (another date value);
ArrayList valueList = new ArrayList();
valueList.add(value1);
valueList.add(value2);
valueList.add(value3);
table.put(key1,valueList);
This would associate "myKey1" with 3 date values stored in an ArrayList.
There is a downside to using the string concatenation method. You assume that the content of each values will never contain a delimiter. You also assume that the values are strings. But if the values are byte[], the string concatenation will not work. If the values are Dates, it can still work, but you would have to convert it from Date to String then concatenate, then get the String value through StringTokenizer and then convert back to Date.
But anyways, if the values are Strings (and won't contain the delimiter character), then the concatenation method would suffice.

How can I create a hashmap() with multiple values for the same key?

I am trying to write an application that will us something like a Map() with multiple values but some have the same key. Is this possible?

i had the same question. just create a List, add all the values u want to it, and then put the List into the map like u would a normal single value. e.g.
List list = new ArrayList();
list.add(value1);
list.add(value2);
map.put(key, list);
i bet u r doing the same course as i am =)
