Showing one data point on a line chart - X-axis label placed away from its actual position

Hi Guys,
     In line chart, i used CircleItemRenderer to show single data point. It shows correctly if it is single data point. But the x-axis label placed away from its actual position. Right now it displayed left most position where the line chart starts. I need to move that label straight of that datapoint where it plotted. Please see the screen shot attached with this post.
In screen shot, x-axis label "Jan" displayed in left most position.
     And how can we show the datatip for single datapoint. At present, we can't able to see the datatips also with single datapoint.
     Can any body help me to fix those two issues.

I figured out a way to customize a single datapoint in a line series. The solution is at this link:

How can I connect dots across missing data points in a line chart?

Hi all!
I have a table in Numbers that I update every few days with a new value for the current date (in this case body metrics like weight, etc.), which looks something like this:
Column 1              Column 2      Column 3
Aug 16, 2011         87.1             15.4
Aug 17, 2011         86.6
Aug 18, 2011         86.1
Aug 19, 2011
Aug 20, 2011         85.7             14.6
Aug 21, 2011         85.3
Every once in a while there will be a missing value for a given date (because I didn't take a reading on that day). When I plot each column against the date on a line chart, there is a gap where there are missing data points. The line does not connect "across" missing data points. Is there a way to make the line connect across missing data points?
Thanks for any help. This thing has been driving me nuts!

Leave your nuts in peace.
Don't use line charts but scatter charts.
These ones are able to do the trick.
Of course to do that you must study a bit of Numbers User Guide.
In column D of the Main table, the formula is :
=IF(ISBLANK($B),99999,ROW())
In column E of the Main table, the formula is :
=IF(ISBLANK($C),99999,ROW())
Now I describe the table charter.
In column A, the formula is :
=IFERROR(DAY(OFFSET(Main :: $A$1,SMALL(Main :: $D,ROW())-1,0)),"")
In column B,the formula is :
=IFERROR(OFFSET(Main :: $A$1,SMALL(Main :: $D,ROW())-1,1),"")
In column C, the formula is :
=IFERROR(DAY(OFFSET(Main :: $A$1,SMALL(Main :: $E,ROW())-1,0)),"")
In column D, the formula is :
=IFERROR(OFFSET(Main :: $A$1,SMALL(Main :: $E,ROW())-1,2),"")
In this table, select the range A1 … D5
and ask for a Scatter chart.
You will get what you need.
I asked that points are joined by curves
I just edited the parameters of Xaxis and Yaxis to get a cleaner look.
I repeat one more time that knowing what is written in the User Guides is useful to be able to solve problems with no obvious answer.

Line Charts - X-axis Labels as function of X-axis value

Hi,
1) Is there a way to put X-Axis labels in line chart as function of X-axis values ?
For instance, X-axis values are in minutes and I need to show those as Hours.
I'm having Hours as separate column as well, but when its selected as X-axis value column, the line graph is disturbed.
2) Also, how to specify the length/range of X-axis ?
For instance, in dataset if I've x-axis values from 0 to 5 hours but still want to show on graph the X-axis till 8 hours.
Thanks for your help in advance.
Regards,
Sumit

Hi Sumit,
I have tried following things with proper datetime format may be help you.
1> in your applet code you can add below param
<PARAM NAME="XAxisDateFormat" VALUE="H">
it will display your levels in hours for more details please refer Date and Time Format under query template in MII help.
2>In your Query template under date range you can select duration and duration unit.
for 8 hour span you can select Duration = 8 and in duration unit = H
I have tested it for a tag query, may be i did not understand your issue properly but hope it helps you!!!

Line chart x-axis label overloaded with labels

Hi,
I have a Line chart filled by a large resultset (hundreds of rows). Each row contains a decimal value and a timestamp. The interval between timestamps is short so it is impossible to plot every single date/time in the x-axis label because there is no space.
I would like to hide the the x-axis label for most rows and plot this label for each x rows. Something like this:
18/12/2009 09:00            18/12/2009 10:00           18/12/2009 11:00            18/12/2009 12:00
        |---------------------------|---------------------------|---------------------------|
In the previous x-axis example there are many timestamps between 18/12/2009 09:00 and 18/12/2009 10:00 but they are not plotted in the chart. It is possible to do something like this in MII charts?
Thank you,

Hi,
I think Michael is right about the Ticks per label parameter. Looks like it is not working for me because the chart data binding is not behaving as expected.
The chart rowset is composed by two fields: decimal and date time. The date time field is already converted to string. The rowset comes from a BLS transaction.
I think this forum has no support for file upload so I will add links to the xMII workbench screenshots so you guys can see my chart/query configuration.
This is the XACUTE Query used by the chart: http://www.vetta-group.com:8080/imgs/xacute_config.PNG

When I run the chart I get this result: http://www.vetta-group.com:8080/imgs/chart1.PNG
As you can see the chart has no X-Axis labels ans I need to add the date/time to the X-axis. If I add the field to "X-Axis label columns" the field values are ploted but the parameter "Ticks per label" is ignored and hundreds of labels are ploted together and is impossible to read them. I think the "Ticks per label" parameter only works for fields added to Labels columns (in data mapping). The problem I am facing is: when I add the date field (http://www.vetta-group.com:8080/imgs/data_mapping2.PNG) to Label columns I get an empty chart like this: http://www.vetta-group.com:8080/imgs/chart2.PNG
What am I doing wrong?
Thank you

Data Point Symbol in Line Graph - can you change the size?

I would like to change the Data Point Symbols in line graphs - if not the actual symbol it would be wonderful to be able to change the size of the symbols provided.
At present, if there is a lot of data in the graph, the symbols are too big and crowd one another.
I know that one can reduce the line size but that doesn't change the symbol size.
Help please.

If I understand your question, this from the Pages online help may give the answer:
To mark line, area, and scatter charts with data point symbols:
Select the entire chart. You can also select the chart series (the line or area shape) that you want to mark with data point symbols.
Click Inspector in the toolbar, and then click the Chart Inspector button.
Click Series (except for scatter charts).
Choose a symbol from the Data Point Symbol pop-up menu.
Choose one of the following options from the Symbol Fill pop-up menu:
To fill the symbol with the same color as its outline, choose Use Stroke Color.
To fill the symbol with a solid color, choose Color Fill, click the Fill color well, and pick a color.
To fill the symbol with a gradient, choose Gradient Fill and use the gradient controls to set the colors and change the angle of the gradient.
To fill the symbol with an image, choose Image Fill and select the image you want. You can also resize the image by choosing an option from the pop-up menu above the Choose button.
To fill the symbol with a tinted image, choose Tinted Image Fill and select the image you want. Click the color well to the right of the Choose button to change the tint color. You can also resize the image by choosing an option from the pop-up menu above the Choose button.

How to save one data point at every 10th cycle?

Hello,
I am using LabVIEW 5.1 and PCI-6023E. In my application, I need to detect peak values from a load cell and save the one data point that detected at every 10th cycle. Do you know any ideal way to do this? Mine always save data values the whole time that the condition is true which is about 26 values; not one value as I want. Any help would be greatly appriciated.
Hao

Hello Justin,
Thank you very much for helping me out. I did not state my question clearer last time. Actually, the cycle here is the number of life cycle of a valve that being tested; therefore, the iterator i can be any number when the valve's life cycle reaches its 1st, 11th, 21st....cycles. Do you know any other way to do this?
Thank you in advance

Grab one data point

Hello,
I am writing a labVIEW program that is measuring strain as well as load. I have the DAQ Assistant set up within a while loop and I condition the signal first, then extract a portion of the signal and then collect that portion of the data before I take the measurement readings. I need to be able to tare the data as well as grab only one data point at a time from each instrument when I want to grab the data.
Eventually I also need to write the information to an excel file.
Is a while loop the way I should be tackling this?
Thanks-!
P.S. I'm using LabVIEW 10

For continuous data acquisition you use while loop. so yes, you are on the right track. Is that all you are asking?
Kudos are (always) welcome for the good post. :-)

Chart not showing last data point

I have a chart that contains data points, 11/15/2000, 11/15/2001, etc. Each data point is plotted in a line graph. There are 11 data points, from 11/15/2000 to 11/15/2010. For some reason, the last data point is plotted on the line graph but there is no label for it on the x-axis. Does anyone know why that may be?
Thanks in advance,
Zack H.

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

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?

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

"no data found" in SVG Line Chart

Hello,
I have a problem with a SVG Line Chart!
I have multiple series in the Line Chart, which data is based on multiple select lists.
When I leave one select list blank, so that one line has no data, the "no data found" statement appears in the Chart.
But when I delete the "no data found" statement in the Series Attributes it would not be deleted. Nevertheless when I open the Series Attributes again the message is still there....
Does anybody have an idea how I van delete the "No Data found Message"???
Thanks,
Tim

Chris and Cristoph -
I have found that many times errors like this are caused by SQL statements that don't really address the business need or the requirements for the chart. Let me use a simple example:
SELECT d.dept_name dept_name,
       sum(s.sales_total) sales_total
FROM orders o, depts d
WHERE o.dept_id = d.dept_id
AND o.time_frame = 'Q1'
GROUP BY dept_nameSeems simple enough. But what if this statement is run early during the Q1 timeframe and one dept hasn't made any sales yet? Well, they won't show up in the output of this statement. From a business perspective, you will want that dept to show on the report with a zero total sales. You don't want them excluded from the report. So how do we fix this?
There are several options.
One dirty way of solving this is putting in a dummy record for each dept into the orders table with a 0 sales_total value for each time unit. YUK! That has wrong written all over it!
We could use a different type of join. And then use NVL or a Case or IF statement to turn Null Values into 0.
SELECT d.dept_name dept_name,
       sum(nvl(s.sales_total,0)) sales_total
FROM orders o RIGHT JOIN dept d ON d.dept_id = o.dept_id
WHERE o.time_frame = 'Q1'
GROUP BY dept_nameWe could also square our data sets and summarize with an inner select
SELECT dept_name dept_name,
       sum(sales_total) sales_total
FROM (
SELECT d.dept_name ,
         sum(s.sales_total) sales_total
FROM orders o, dept d
WHERE o.dept_id = d.dept_id
    AND o.time_frame = 'Q1'
GROUP BY dept_name
UNION ALL
SELECT DISTINCT dept_name ,
         0 sales_total
FROM dept
GROUP BY dept_nameThe final result is that every dept has a value. That is the key. This is how the chart expects the data and this is probably how your business expects the data.

How to make use of a different data model for a line chart?

I have a datamodel which is a sql query. I have a line chart on my template which is using some "Start Time" field as X-Axis. There is a chance that "Start Time" is null. In such cases the plotted point doesn't appear with x-coordinate. But I can't change the X_Axis field to some other not-null attribute due to business requirement.
I am thinking to create another datamodel which filters all "Start Time"s which are nulls and use that datamodel for the line chart that has "Start Time" as X-axis. But I don't know how to do this as whenever I try to insert a line chart from BIPublisher menu in MS_Word, I am not prompted to select the datamodel.
Can anybody tell me what I am trying is possible? If so how? If not, how do I have "Start Time" as X-axis without hassles?
Thanks,
-Vijay-

Are you able to extract the data based on the new data model in an XML file? If so, in BI publisher desktop, are you able to load the XML data via Add-Ins ->Data -> Load XML Data?
If you have been able to load the data successfully, then you need to Select Chart from the Insert Menu. When you do that, you should be able to see the Data layout on the left side of the chart dialog box. Then you should be able to drag and drop fields as necessary to create the chart. Are you having issues doing this part?
You will not be prompted to select the data model. Hope I haven't misunderstood your question.
Thanks!

Getting BEx query header data into Xcelsius for line chart Category Labels?

Hello - Is it possible to get header data from BEx queries into Xcelsius so they can be used for Category Labels in a line chart?
We have a BEx query that displays 16 weeks of shipment trends by column and text variables are used to display the respective date selection for each of the weeks in the query header but When connecting QaaWs to Xcelsius, the header row does not get displayed.
When using LiveOffice, the header row seems to come thru with the correct dates for each of the weeks but if you are stacking more than one connection than you will get an extra header row for each connection.
Are there any tricks to hide a header row in a LiveOffice document?
Is there anyway to display the header row from QaaWs in Xcelsius?
Any other work arounds?
Thanks,
Derek

Derek,
Below are my inputs...
-->Using QAAWS you will not be able to get the header data, so you will have to maintain header data manually in Xcelsius (Spreadsheet).
-->Using Live office you will be able to get the header data, and if you are using multiple live office connections, then you need to use cell reference formulas and format the spreadsheet (Xcelsius) as you require.

How to limit data range in a Line chart with Time Refresh Control

Hi All,
I have a Line chart with Time Refresh Control and I would like to make some constraints to this navigation.
For example, I would like to limit the user to navigate in a data range of 8 hours.
Is this posible?
Thanks in advance

Hi Pedro,
as far as I know, this is not possible using the time controls on an iChart. However, you may have some success by using your own time controls which call JavaScript methods exposed by the applet.
For example, you could begin by hiding the time and calendar buttons on an iChart, and creating some buttons of your own. For instance, to set the start date of a query (and thus the start date of the iChart using the query), you can use the following:
document.getElementById("appletID").getQueryObject().setStartDate(<date string>);
Using code like the above (look into the xMII script assistant and documentation), you should be able to build time controls which satisfy your requirements. The exact format of <date string> in the sample above will depend on the date format defined in the query template this script calls.
Hope this helps,
Sascha

How to set maximum number of data points displayed on waveform chart?

I have a waveform chart set to x-autoscale, but after about 1000 data points, it begins to scroll again. How can I display all of the data points being collected, say 2000 points?

Right click on the chart and select Chart History Length. Enter the value that you need. The maximum is 2147483647 points.

Boolean indicator come on and stay on if only one data point outside of limits

Okay, here goes my second rookie question. My first one was solved in a matter of hours after posting here, so I am going to give it another shot. This has probably been posted elsewhere, but I just am not familiar enough with the terminology and know how to find it in this forum... sorry for that.
Currently, I have a setup where I am using an In Range and Coerce function in the Comparison Pallette to check the output of my source and compare it with a user inputted upper and lower limit. I have hooked up an LED indicator to the Index Array and then to the In Range output. Right now, if my data goes outside of the limit, the LED Indicator will light up, but it will immediately turn off if the data goes back within the limits. I want my LED indicator to come on and STAY on if even 1 data point goes outside of the limit. What can I connect between my LED Indicator and my In Range Comparison to make this happen?
Sorry for being so new to this!!

Hi Spsuengr,
I have attached a boolean toggle vi for you. You can insert this vi in between your led indicator and in range output. It will latch the output by default. You can use the latch(t) input to disable the latch feature (to perhaps reset).
Above is the boolean latch vi
Above is how you need to insert it into your code. If you leave the Latch(t) input unconnected it defaults to a latch output. Only wire a control to this if you want to either change the output so it follows the input or if you need to reset the output.
Rgs,
Lucither
