Creating a Line Chart in Apex

Hi, I'm a new Application Express user, and I've been trying to create a chart region in one of the pages of an application I'm developing, only my queries fail and tell me that my tables that clearly exist do not exist. Btw, the table I'm querying exists in a different schema. Any ideas?

Have you noticed the Oracle Application Express (APEX) forum?
Could be a permission problem, but I'm only guessing.

Unable to create a Line chart

Hi Friends,
I am trying to create a Line Chart based on CalMonth, where I want to show no. of SalesOrg denoted by different lines separately according to their monthly sales.
Please help.

Hi,
To create chart this is the process..
    1.      Before you begin publishing a chart, you need to specify which chart type ( Line chart in your case ) you want to display. You can determine how the data provider is to be built by using the class of the chart type.
       2.      Select an existing query or design a new query with which you can generate a suitable view of the data, that is, a suitable data provider.
       3.      Start the publishing process and create a new Web item of type Chart.
       4.      We recommend configuring the properties of the chart Web item as follows:
○       Expanded hierarchy nodes should be hidden.
○       Totals should be suppressed.
○        If you want to swap the data providers in the chart, you should assign the Swap Display Axes property to the chart. The columns and rows are then swapped automatically when the chart is generated. You do not need to change the view on which the chart is based.
       5.      When you edit the chart, the Web Application Designer or Web Application Wizard first shows the default setting, that is, a column chart.
○       Firstly, format the chart using the wizard so that the most important settings and the number of displayed data series and data points correspond to your data provider (see also Formatting a Chart Using the Wizard). Assign the required chart type to the chart and format the chart as required.
○       All chart elements that you can format are displayed in the list of properties on the right of the screen. You can modify the properties as required here.

Create a line chart

I wont to create a line chart using a a PL/SQL script. If is possible, i wont put this script inside a report created using Web DB, as an action that it must run after the show of the report html page. Is possible to make that? what i can do?
Thanks a lot!
null

PL/SQL has no graphical capabilities whatsoever. However it is possible to represent values like this
X A ----
B --------
C -----
012456789
Y
in which for each row (the X axis) a substr() of the value '----------' is created using a value from the query (the Y axis).
Is that clear? Let's try an example. To print graphically the lengths of a column:
SELECT col1 as "X", substr('----------',1, length(col1)) as "Y"
FROM your_table;Not very pretty I grant you. But if you want pretty you'll have to use Oracle Graphics (now part of the Developer toolset) or java.
Good luck, APC

Charts (Line chart) in apex 2.0 /3.0 limit of resulting rows in char area

Hello @apex experts,
does any body knows if there is a max number of resulting rows by using a line chart. It seems that until 150 resulting rows all is o.k. but when I try to get a line - chart area for a whole year (365 days) no chart is displayed. I spread out the chart area to 2056 x 800 px but no restult is displayed by using the > 300 resulting set.
Regards and thank you for help

I changed this and put usage of UTL_FILE into a dynamic PL/SQL. The package will
compile and work unless you want to create debug information. If yes, then it will raise an
error message. So, you don't need UTL_FILE execution priviledge from your DBA.
I opened the package and you may modify it the way that you don't need any public
synonyms and no UTL_FILE to run it.
There are so many questions in this forum related to "What is my DBA going to say?" or
"How is he going to react?". Even for some minor issues. I have myself also seen some
of similar situations and the only thing I can sey is:
You got to use that powerfull tool Oracle Database instead of hiding it away from your
users and developers. Learn how to control it instead of prohibiting access to it! Otherwise,
it's just a waste of money.

Covered Line Chart in Apex

Hi,
In Apex there are several types of charts but I dont find the covered Line chart. Is there any function to create a covered line chart with the lite Version? For example: I have a blue line and I want to have a blue covered area up to this line. I am using Oracle Apex 4.0 and i dont find this kind of chart in the chart types. Am I able to change the custom XML to this type of chart?
Thanks Thorsten

Hi Thorsten,
I believe the chart type you are referring to is an Area Chart, where the region from the chart axis to the line on the chart is coloured in. This chart type is not one of our licensed AnyChart chart types. You are only licensed to generate AnyChart chart types that are exposed via our wizards. For the generation of any other AnyChart chart types, you will need to obtain a separate license from AnyChart.

Creating a Line Chart using a user enter target amount.

Hi all,
I'm trying to create a chart that will use Total Sales and Annual Target(Goal).
I get the Total sales to work just fine. It's just getting the Annual Target(Goal), which is a parameter, to come into the chart. Right now they are doing this in Excel and the Target line goes from 0 to 8,000,000.
So how do i get that to work in my Crystal Report?
So when the report is working correctly i should have a Line Chart with two Lines. Line 1 "The Target", Line 2 "Total Sales".
Thanks

Hi
Create a formula field and store the parameter there.
Now put this formula field in "On change of" in the Chart expert.
e.g. I have a parmeter on country and I have a chart which shows the last year sales year wise for the countries.
I create a formula field and put the below formula:
stringvar x = {?countryparameter};
Now i put this formula field in On change of so when i run the report i select the required country.
Hope this helps!!

Creating a Line Chart

I would like to create a line/bar chart with the following details :
y-axis : total bytes in, total bytes out
x-axis : hour
I want to display each hour the number of bytes in/out transferred in a day.
But my db doesn't have some hours which doesn't have data.
i need to display another chart , for each 15 minutes(ex.if its 2 hour - 2:00,2:15,2:30,2:45) bytes in / out should be displayed for an hour.
Any suggestions.
Regards,
Parsa.

Hi Ramesh
For example you have a item field in your database but you do not have some values for them in the database.
In this case you can create a formula field and assign the item names to the variable. In case you have more than on item, you can use an array as well (for help on array, simply open Crystal Reports Help -> Index -> Type array.)
Now you can create a group based on that field and insert a chart.
Hope it helps!!!

Line Chart in Apex

Is it possible to change color of line graph based on a condition? I want to show red if the line passes above 90 percent and then show green when the line drops below 90 percent. Can someone help me on this?

I'm sorry, my instructions were not very clear about posting code. Lets try that again. First off, I mistakenly instructed you to use a [ character when the correct character is {. I evidently need to learn how to use the shift key properly. The best way to post code is by enclosing it in {code } tags. So, when you post, it will look like {code }Your XML here{code } (again, no spaces in the tags). The output will look like:
Your XML hereMore info about this can be found: http://wikis.sun.com/display/Forums/Forums+FAQ
Next, onto the real question at hand. It appears that you are getting close. Your page item P50_DATA should define each data point in the chart. It should begin with a <data> tag and have at least one <series> tags, with points defined. Your current PLSQL output is an example of one of the points that would belong in the series. If you turn on DEBUG, a link will appear next to your chart labeled 'Show XML'. click that link to see the entire XML that is rendering your chart. Once you have that, post it here if you need help reading it.
Getting back to your PLSQL output, in the code you will need to determine which style each point will use. I assume this will be based on the Y value. An example of how to do this: <point name="GREEN" y="1" style="style1"></point>
<point name="RED" y="97" style="style2"></point> As mentioned earlier, you will need more than just the example code given above in page item P50_DATA. You will need the entire XML string from the beginning <DATA> tag to the </DATA> tag.
Hope this helps

How do I create a line chart direct from xml or convert xml to ArrayCollection

The xml is simple:
<data>
<row name="Q1">
<expenses>64</expenses>
<revenue>98</revenue>
<profit>34</profit>
</row>
<row name="Q2">
<expenses>44</expenses>
<revenue>28</revenue>
<profit>64</profit>
</row>
<row name="Q3">
<expenses>14</expenses>
<revenue>58</revenue>
<profit>54</profit>
</row>
</data>
it's dynamically generated as a string so could be created in xml format, or ArrayCollection, or any other format that works. However I can't find a example of using xml as the datasource that works. I've tried to convert it to an ArrayCollection first but that didn't work either.
Alternatively I could store the data as a string "Month: "May", Profit: 2400, Expenses: 575, Amount: 456", then:
expensesAC2.addItem({Month: "May", Profit: 2400, Expenses: 575, Amount: 456 });
works but:
var settings:String = resultXML.row[0];
expensesAC2.addItem({settings});
doesn't work. Any suggestions, or links to a tutorial that works would be really appreciated?

Hi all,
This issue was resolved off-line, however, I wanted to note a few points that were shared with me.
Learnings from Forum discussion:
Best practice is to use a combination of INDEX and MATCH functions instead of Vlookups. Using the VLOOKUP function can result in a very slow dashboard if using a lot of data.
Also, when using the Filter Component note the destination field as the filter component does not copy the first filter value at all so you have to adjust by one column to accommodate for this (two columns if you have 3 filters etc).

What is the best way to create a SSRS 2005 Line Chart Report for a 12 month period?

I'm looking for advice on how to create a SQL Server 2005 query and line chart report for SSRS 2005.
I need to display the peak number of patients assigned to a medical practice each month for a 12 month period based on the end-user selecting a
single month and year.
I've previously created a report that displays all patients assigned to the practice for any single month but I’m looking for advice on how to
how to produce a resultset that shows the peak number of patients each month for a 12 month period. I thought about creating a query that returns the peak count for each month (based on my previously created report which displays all patients assigned to the
practice for any single month) and then use a UNION statement to join all 12 months but I'm sure that isn't the most efficient way to do this. The other challenge with this approach (twelve resultsets combined via a UNION) is that the end-user needs to be
able to select any month and year for the parameter and the report needs to display the 12 month period based on the month selected (the month selected would be the last month of the 12 month period).
For the report I’ve previously created that displays all patients assigned to the practice for any single month, the WHERE statement filters the
resultset on two fields:
Start Date - The date the patient was assigned to the practice. This field is never null or blank.
End Date - The date the patient left the practice. This field can be null or blank as active patients assigned to the practice do not have an End Date. When the patient
leaves the practice, the date the patient left is populated in this field.
Using these two fields I can return all patients assigned to the practice during Nov 2012 by looking for patients that meet the following criteria:
start date prior to 11/30/2012 (using the last day of the month selected ensures patients added mid-month would be included)
AND
end date is null or blank (indicates the patient is active) OR the end date is between 11/1/2012 -11/30/2012 (returns patients that leave during the month
selected)
Regarding the query I need to create for the report that displays the peak count each month for 12 months, I'm looking for advice on
how to count patients for each month the patient is assigned to the practice if the patient has been assigned for several months (which applies to most patients). Examples are:
John Doe has a start date of 6/01/2012 and an End Date of 10/07/2012
Sally Doe has a start date of 8/4/2012 and no End Date (the patient is still active)
Jimmy Doe has a  start of 7/3/2012 and an End Date of 9/2/2012
Given these examples how would I include John Doe in the peak monthly count each month for May - October, Sally Doe in the peak monthly count for
August - December and Jimmy Doe in the peak monthly count for July – Sept if the end-user running the report selected December 2012 as the parameter?
Given the example above and the fact I'm creating a line chart I think the best way to create this report would be a resultset that looks like
this:
Patient Name
Months Assigned
John Doe
June 2012
John Doe
July012
John Doe
Aug 2012
John Doe
Sept 2012
John Doe
Oct 2012
Sally Doe
Aug 2012
Sally Doe
Sept 2012
Sally Doe
Oct 2012
Sally Doe
Nov 2012
Sally Doe
Dec 2012
Jimmy Doe
July 2012
Jimmy Doe
Aug 2012
Jimmy Doe
Sept 2012
From the resultset above I could create another resultset that would count\group on month and year to return the peak count for each month:
June 2012 - 1
July 2012 – 2
Aug 2012 - 3
Sept 2012 - 3
Oct 2012 - 2
Nov 2012 - 1
Dec 2012 - 1
The resultset that displays the peak count for each month would be used to create the line chart (month would be the X axis and the count would
be the y axis).
Does this sound like the best approach?
If so, any advice on how to create the resultset that lists each patient and each month they were assigned to the practice would be greatly appreciated.
I do not have permissions to create SPs or Functions within the database but I can create temp tables.
I know how to create the peak monthly count query (derived from the query that lists each patient and month assigned) as well as the line chart.
Any advice or help is greatly appreciated.

Thanks for the replies. I reviewed them shortly after they were submitted but I'm also working on other projects at the same time (hence the delayed reply).
Building a time table and doing a cross join to my original resultset gave me the desired resultset of the months assigned between dates. What I can't figure out now is how to filter months I don't want.
Doing a cross join between my original resultset that had two dates:
08/27/2010
10/24/2011
and a calendar table that has 24 rows (each month for a two year period)
my new resultset looks like this:
I need to filter the rows in yellow as the months assigned for stage 3 that started on 8/27/2010 should stop when the patient was assigned to stage 4 on 10/24/2011.
You'll notice that Jan - Sept 2011 isn't listed for Stage 4 assigned on 10/24/2011 as I included a filter in the WHERE clause that states
the Months Assigned value must be greater than or equal to the date assigned value.
Any advice would be appreciated.

Problem creating line chart with character data

Post Author: burkartt
CA Forum: Charts and Graphs
CR Developer v. 11.5.0.313
I want to create a line chart with data from a SQL2K table to show how much server time each application uses per day. All data is defined a character.
HWA,4/24/2007,01:44.6HWA,4/25/2007,12.28HWB,4/24/2007,4.6HWC,4/24/2007,55.55HWC,4/25/2007,01:22.3HWE,4/24/2007,01:16.1HWE,4/25/2007,0.59
I want one horizontal line per application where the X-axis represents the date and the Y-axis represents the server time. I have tried all column combinations for "On Change Of" and "Show Value(s)". What confuses me is why are Count and Discount the only Summary Options for the "Show Value(s)" data?
Thank you,

I created a group based on date, day, then created the chart and put it in the group footer, on change of server, show sum of time, you will get a seperate chart for each day. I am not sure if this will help, or will just do. Since you have CR XI, you may want to look at the gauge chart also....
