Line chart - add 3rd value to each datapoint

I have a chart with stock trades:
http://www.psychobanker.com/main.php
I'd like to add the name of the person who made the trade to each value so that when the user hovers with the mouse over the chart, he can see who made the trade. How can I achieve this? Adding another value to the arrayCollection has no effect. The chart always only displays the xvalue and yvalue.
thanks

Hi,
Use dataTipFunction.
Here is a an example .It has PieChart, but you can do the same thing with line chart.

Line Chart - number of values it can chart

Is there a limit to the number of values the line chart is able to chart? It appears when too many results are returned the chart truncates the last data points. When I look at the data all values are present but the chart only charts the first ? values.

Sam,
How many values are you trying to plot on a chart. There is not necesarily a limit but will be limited to the size of your chart and considering you can plot one point per pixel this will depend. We recommend the option in the iChart of "Use Screen Resolution" as this will limit your data points to the size of the screen otherwise it can get very unsightly and confusing, if you have a chart which is 640x480 and are bring back 2,000+ datapoints and plotting them this will be very confusing and most likely counter productive.

How to adjust x axis of line chart for dynamic values from universe

Dear All,
I am new to SAP Dashboard. I got one requirment that, user will pass single value to universe using prompt in Dashboard. Based on that prompt value / input parameter, universe will deliver data to plot line chart in my canvas. But, on every request i will get different count from universe. Like for request A = 30 records, request B = 56 records, request C = 2 records and so on.
Based on the count, i want to display line chart in my canvas which will auto fit the screen. (Auto adjustment of X axis e.g For A, last record on x axis should be 30, for B = 56 and for C =2). Please let me know, how can i achive this task?.
Note : i know, how to plot simple line chat with fix count.

This is based on the output you get for the selection, get in touch with the functional team and get an idea about maximum no of result set will appear on various selection options. Say example if the functional guy says around 100 then go ahead and map 100 cells for the series.
Then as arijit said you can use the ignore blank cell option to eliminate the blank rows in the selection.
Note: Eliminating blank cells will always work at the end of the rows, not in the middle of the rows.

APEX multi series line chart with different markers for each series

I am using APEX 4.0 and trying to create a multi-series line chart that will have a different for each series.
Does anyone know how to accomplish this?
Edited by: user4635837 on Apr 19, 2011 7:22 AM

Hello -
It is possible to do.
Another user in this forum has written some code snippets to assist in creating your own custom XML for charting. That reference can be found http://apex.oracle.com/pls/apex/f?p=36648:30:418355095936797::NO:::
Look this over and it should get you moving in the right direction.
What you are trying to do isn't terribly difficult. In fact, I did it fairly easily as can be seen http://apex.oracle.com/pls/otn/f?p=28155:4:362637005964920:::::
First, create a Hidden page item.
Next, create a process that runs before regions
That process will create the XML for your line chart and store it in the hidden page item. Use the above references for assistance in setting up the PL/SQL in the process
Then, create your custom XML for your chart. Replace the #DATA# tag in the custom XML with your hidden page item.
It is a bit daunting at first, but once you get the hang of it, it really isn't that bad.

Line chart showing final value only?

Is there a way to have a line chart that shows the value against the final data point only?
eg something like this
----------------------74
instead of
1----13----28---42----74
Thanks

Thanks I appreciate your comments and agree I will have to put some effort in, I tend to try and work things out I need by messing around when I need a specific function or have a specific thing I want to do and focus on that without perhaps learning the underling basics.
I've been spoiled by Excel, there is a lot of stuff its significantly easier (for me anyway) to do without undergoing any learning curve at all, with wizards for functions (for example) and in many cases if you right click on something you can alter it right there, rather than having to go up to the inspector and work out which of umpteen functions the bit you want to alter is hidden in. If the inspector was a person, I would have strangled them to death by now
I'm not sure if this is my Mac or what, but if I go into numbers help and type anything in, I just get the spinning thing next to the magnifying glass, but it never comes back to me. It works OK if I follow links. For example I just typed 'charts' in help and hit enter, 5 minutes later I"m still waiting. Doesn't increase my confidence I'll have to look into that and see whats going on.
Thanks to everyone for your help, the guys will be impressed with the new chart !

Line chart with mutiple value formats

Hi,
I have a chart built with Crystal Reports 2008 with two column lines. One of the lines represents Quantity and the other line represents Percentage. I set two Y axis (Y1 for Quantity line and Y2 for Percentage) for the two lines. My problem is that when I set one of the lines' value format as Percentage, value format of both lines become percentage. I cannot set one of the line value formats as percentage and the other one as number. Would you please advise how I can set one of the line's value format on the chart as numbers and the other one as percentage?
Thanks,
Al

Hello Al,
How exactly are you setting one of the lines' value format as Percentage?
And what are you setting it to be a percentage of? or are you trying to dsiaply one series data labels with a percentage symbol?

Show Timestamp on Y axis in a SSRS line chart.

I have a column with datatype as timestamp. And i want to show that column on Y axis in a line chart. two sample values from that column are 03/01/2014 11:30 PM and 03/02/2014 12:10 AM. In this case the data point for first value should be less compare
to the second one, i.e. the series should consider the complete timestamp. Is there a way in SSRS to achieve it.
If I only take the time value from timestamp on Y axis and plot the chart then the data point for 12:10 AM is less than the 11:30 PM, which is not true in this case.
ApoorvaW

Hi ApoorvaW,
In Reporting Services, if we directly add the Timestamp field to Y Axis, it displays the count values in the line chart. When we modify the expression of the value to [Timestamp], it displays the date value in the Y Axis. Though it displays date type as
the axis label, it represent the complete timestamp.
So in my environment, the timestamp display very well in the line chart. If there are any misunderstanding, please elaborate the issue for further investigation.
Thanks,

Line Chart & "don't summarize"

Post Author: HelenW
CA Forum: Charts and Graphs
I am trying to create a simple line chart showing the value of an integer variable plotted against the time of day (24 hours). My problem is that when I choose the field that I want to plot, the checkbox for "don't summarize" is disabled, and I have no choice but to summarize the data. I am using Crystal Reports XI Release 2. Any suggestions?
Thx
Helen

CA Forum: Charts and Graphs
Hi Helen,Had the same problem. Interestingly, the solution is that the "Don't Summarize" field is only available for formula fields.If you don't want to summarize a field, create a new formula which returns the value of that field. That should do the trick.Source: http://publib.boulder.ibm.com/infocenter/radhelp/v6r0m1/index.jsp?topic=/com.businessobjects.integration.eclipse.doc.crdesigner/reportdesigner/crurfchartexpertdatatab.htm - Sri

Merging two line charts into 1

We have two line charts depicting some figures over each week in a year. The line charts project counts on different criterias. We want to have only one chart depicting
both the lines. Please help us out on this one.
thanks
Sameer

I meant have one criteria (one query).
so you'd select :
week of year,
count(Fixed Bugs),
count(reported bugs)
in the same criteria, then select both measures on the 'line' and the week of year on the x axis of the graph?
Any reason why you cant build them into one criteria?
BTW are you measures defined the RPD or are you creating them in Answers on the fly using count() function?

Display column values as a series/legend on a line chart where one column value can be more than one category

Hi Everyone
I don't know if this is possible or not, so I will describe it. I have a column in a table called Filing. There are currently three values in it ("Abuse", "Neglect", "Voluntary") and each record has this populated. I also have
the below slicer for the column also.
I would like to add a fourth value called "Abuse/Neglect" that would identify instances where both an Abuse and Neglect petition was filed, which is a subset of the Abuse and Neglect records in the Filing column.
My question is, is it possible to create a line chart that has the 4 Filing possibilities: "Abuse", "Neglect", "Voluntary", "Abuse/Neglect" as the Series/Legend in the line chart?
The problem is that there are records that are more than one category: Abuse or Neglect records can also be Abuse/Neglect.
Paul

Hi Paul,
According to your description, there is a column with the values ("Abuse", "Neglect", "Voluntary") in your table, now what you need to is that add another value "Abuse/Neglect" in this column, and then use it
as Series/Legend in the line chart, right?
In this case, you can add calculated column to your table based on your logic. A calculated column is a column that you add to an existing PowerPivot table. Instead of pasting or importing values in the column, you create a DAX formula that defines
the column values. The calculated column can be used in a PivotTable, PivotChart, or Power View report as you would any other data column. Please refer to the link below to see the details.

Hint Values on Line Chart

When you setup a line chart, the LABEL portion of the SQL query becomes the X axis value on the line chart. When there are multiple series on a line chart, each series is its own distinct line. If the series has a LABEL that is not yet on the chart, it adds that label to the x axis at the end of the axis. If the new series has a LABEL that is already on the chart, then it places the Value on that existing place on the x-axis. This Label is also used in the Hint portion of the chart.
So lets compare the number of Sales per day of a Department across a length of time, say 3 months. So, on first working day on Jan dept A has 31 sales. On the second working day of January thay make 35 sales and so on until March 31. Our company doesn't work on weekends so we won't have sales on those dates. Dept B has their numbers for the same dates.
We setup a series for each month (Jan, Feb, March). Then we place the total number of orders for each date on the graph and connect the dots! Great! But wait, the more months I add, the shorter each line gets on the graph. What if we were comparing 3 years worth of data instead of 3 months. The x-axis would have 600-700 values instead of 60-70 values. Oh my.
What if we make each series of data its own line over the same scale? That way each month shows in the same space with the first day of the month at the left and the last day of the month near the right. Sounds good. But wait, we are now making up a scale. And when we do this, the Hints on the data points become meaningless. I want to show the actual date value in the hint but have the line over my custom X-Axis. What I need is an additional field that I can use to add to the Hint portion of the chart. Obviously, this would require using custom xml and a custom data element, but is this even possible given the constraints of the SQL syntax?
To visualize this issue better: http://apex.oracle.com/pls/otn/f?p=28155:1
Austin

Andy -
I need to thank you for the direction on the substitution variables reference. That will be a major help.
However, i must correct a statement (underlining is mine)
So, if you switch to Custom XML and find the <tooltip> tag and add {%SeriesName} after the existing {%Name} entry, you end up with the _"day of the month" (which is your value)_ and the Series Name value, which is January - so, "1 January"This is a common misconception that the numeric value on the x axis represent the "day of the month" , when in fact it does not. You logically cannot use the day of the month for this type of axis. Why not? It is because weekends are excluded. So, one month may begin on a Friday. If that were the case then the 2nd of the month would be a Saturday, which would work for a single series of data. But what about when you add in the next month and it begins on a Tuesday. Well then, if you use the day of the month as the value, the 2nd day of the second series actually gets plotted after all the days of the first month.
The solution is that you have to generate a common arbitrary scale for all series of data. When you do that, you lose the date values.
I have tried to illustrate all of this by adding to the existing examples in the link provided above. Some other odd behaviors of using the day of the month as the x-axis value can be seen as well. I have also implemented the suggestion of adding the {%SeriesName} tag to the Hint via the custom xml.

How to add line series dynamically to a line chart in flex?

hi..i need to add line series dynamically to a line chart..depending on an array..the application is this..i have an array which stores the details of the users connected to an fmi server..the chart should display the bandwidth of each client..so the users should be added and removed from the chart dynamically...

Hi
1.I am giving you solution for dynamically adding values to the dropdown
public void addValue( ) //Method Name in Component controller
    //@@begin addValue()
          IWDNodeInfo nodeinfo = wdContext.nodeNodeTestData().getNodeInfo();// Node should be map to the view's Node
          IWDAttributeInfo att = nodeinfo.getAttribute("VechileTypes");// Attribute by which dropdown in bound//
          IModifiableSimpleValueSet svSet = att.getModifiableSimpleType().getSVServices().getModifiableSimpleValueSet();
          svSet.put(wdContext.currentNodeTestDataElement().getInpAtt(),wdContext.currentNodeTestDataElement().getInpAtt());
    //@@end
2.   wdThis.wdGetLangCompController().addValue(); // call this method in the point where u want to add values to the dropdown.

Simple Line Chart - Values over time

A simple line chart displaying a set of values over time would seem to be a very easy report to design. I'll be darned if I can see how to design it. Can anyone shed some light?
I have provided links to a report and a spreadsheet which is the report datasource. My actual report will use SQL Server as its datasource. I am providing ths excel based example for the sake of protability.You will need to set the datasource location after saving the files to your hard drive.
I can get the lines to draw properly, what I cannot figure out is how to specify the datetime values for the x axis. The column I would like to use on the x-axis is called DerivedLoggingTime.
I'd also like to get control of the logarithmic algorithm used to formulate the y-axis values. I am not always happy with the values that the log algorithm comes up with.
Any help is greatly appreciated.
[Link to report|http://www.usol.com/~joe/linechart.rpt]
[Link to spreadsheet|http://www.usol.com/~joe/AnalysisResults.xls]
Another discovery while working on this report - our database will be SQL 2008 and we are making use of the datetime2 datatype. CR appears to be treating this datatype as text. So when working with the SQL based datasource, I had to cast datetime2 columns as datetime in order for CR to see the columns as datetime instead of text. This is fine in this instance because the granularity of the datetime values for this particular report does not require datetime2, but that will not always be the case. CR will need to recognize the new datatype.

Hi Joe,
The Date Axis Line Chart of the Numeric Axis Type Chart, can be used to display data on a regular interval of days, Months and Years. The information displayed can unfortunately not be more granular that days.
This type of chart is generally used when the data is recorded on irregular intervals in the database, and to make sense of the information stored it needs to be displayed at regular intervals.
Since the data stored in your data source seems to be stored every 4 minutes, it will not be necessary to use this type of chart. I will suggest to use the regular line chart instead.
To create a line chart using your date time field and value:
1. Select "Chart" under the menu "Insert"
2. Insert the chart on your report in the desired section.
    ( Group Header # 3 in your case. )
3. In the "Chart Expert" window, under the tab "Type",
    change the chart type to a line chart by selecting "Line" in
    the "Chart Type" list.
4. Under the tab "Data", add the database field that contains the Date Time information under the "On change of" list.
(In your case, add the "DerivedLoggingTime" database field)
5. To display the data for each minute, select the database fields you just added under the "On Change of" list, and
click on the button "Order". In the "Chart Sort Order" window,
select "For each minutes" in the "Section will be printed" drop down list, then click "OK"
6. Add the field you want to display the value in the "Show Value List", then click "OK"
Now it will display a line chart as desired, but since there is a lots of data point on your chart, the x axis date time labels will overlap each other. To avoid this situation, I will suggest to skip labels.
To format a chart to skip labels:
1. In the "Preview" tab of the report, select one of the x axis label, and right click on it. In the contextual menu, select "Group (X) Axis Options..."
2. In the "Group (X) Axis Settings" window, under the tab "Layout", check the option "Skip Group Labels" and set the value to 15 for example.
Now, it will display the date time label at every 15 data point.
As for your question on how get control of the logarithmic algorithm used to formulate the y-axis values, we unfortunately do not have much control over it other than:
- Entering static values, or
- Checking or Unchecking the option "Use Logarithmic scales"
The above options are available on the y axis. To change those options:
1. In the "Preview" tab of the report, select one of the y axis label, and right click on it. In the contextual menu, select "Group (Y) Axis Options..."
2. In the "Group (Y) Axis Settings" window, under the tab "Scales", you will see the following options:
- Minimum Values
- Maximum Values
- Use Logarithmic scales
I will suggest to check the option "Use Logarithmic scales"
Finally, as for the issue you discovered where SQL Server 2008 data type DateTime2 is converted to a string in Crystal Reports 2008, it is important to note that SQL Server 2008 hasn't been released yet, therefore it has not been tested in Crystal Reports 2008. Once SQL Server 2008 is released, I will suggest to test it again using the ODBC driver provided with this new version.
At this point I am assuming that this is happening because it is a new data type and an unknown data type get converted to string.

JDEV 10G: how to display the value of the line chart using jChart in JSP

I have draw the line chart in JSP using the JChart and now I wan to display the value label in the line there..
but the value wasn't show..
anyone can help me..
thx..

Hi,
what I do understand, you want to display the value of each point in your Line Graph.
I guess you will be having BIGraph.xml file. In this file check the "Show Data Tips When Mouse is over bars" checkbox.
Lets try with this.

How to dynamically add new line series to the line chart in flex?

i need to add line series dynamically..and each line series should have a different data provider...

A chart can have only 1 dataProvider which in my case is an ArrayCollection.
The chart will update every time the dataProvider changes if you use binding.
So you have to write a function that periodically populates the ArrayCollection with data from the server and the chart will update automatically.
