Highlighting a single data point in a scatter plot - Numbers'09

Is there a way to highlight a single data point on a scatter plot in Numbers'09 (or point to it using a line from each respective coordinate on the x & y axis).
I don't think it matters but the data point i am looking to highlight is the [highest y value/2]... and of course its respective x coordinate once you plug the y value into the equation ( y = f(x) ) and solve for x.

Here is my own tip :
As you see, I use two sets of values.
In the second one I define only the yValue of the data point which must be "highlighted".

Deleting specific data points from a scatter graph

I cannot seem to figure out how to delete single points in a scatter plot to get rid of the outliers. Someone help me!

I have never used Numbers.
Can't you just delete the data on the source?
The PhD research scientist in me makes me ask you if you are justified in deleting any data points? Even apparent outliers may represent a true data sample. Likewise, how do you know one of the "good" points isn't an aberrant sample that really belongs at an extreme? I would take care of outliers by reanalyzing the sample many times until I averaged it into submission. The only outliers I would outright delete were ones where I could truly question the quality of the analysis based on other data, or it it was truly impossible (e.g., a negative number of apples growing on a tree).
One thing I would do would be make a scatter plot with one set of data and generate my line through it, then generate a second plot on the same page with the outlier data but not plot a line through it. The line would show the relationship I thought really applied but I was also up front about data I had rejected and still presented it for all to see.

How to take a single data point for each trigger pulse ( synchronous acquisition).

hi
          im using the pci-mio-16E1 card, with the IDE VC++, so im looking for an example to explicate me how to make an synchronous acquisition data using an external timing, so the idea is to acquire (take) a single data point for each trigger pulse from one input channel ,and saving the data in a file .
now im making a code using the AI_setup and DAQ_op functions, im getting a speed acquisition (it is the start of acquisition data), and it is a synchronous acquisition just for one trigger pulse, and me i looking for an acquisition for each trigger pulse.
so to  understand my problem you can see my code :
iStatus = Timeout_Config(iDevice, lTimeout);
         iRetVal = NIDAQErrorHandler(iStatus, "Timeout_Config", iIgnoreWarning);
   // configuration and selection of signal trigger
         iStatus = Configure_HW_Analog_Trigger(iDevice, ND_ON, iLowValue,iHighValue, ND_ABOVE_HIGH_LEVEL, ND_THE_AI_CHANNEL);
        iRetVal = NIDAQErrorHandler(iStatus, "Configure_HW_Analog_Trigger", iIgnoreWarning);
iStatus = Select_Signal(iDevice, ND_IN_CONVERT, ND_PFI_2,ND_HIGH_TO_LOW);
         iRetVal = NIDAQErrorHandler(iStatus, "Select_Signal", iIgnoreWarning);
    iStatus = AI_Setup(iDevice, iChannel, iGain);
   iRetVal = NIDAQErrorHandler(iStatus, "AI_Setup", iIgnoreWarning);
   while ((iReadingAvail != 1) && (iStatus == 0)) {
/* Wait until reading is available. */
         iStatus = AI_Check(iDevice, &iReadingAvail, &iReading);
        iRetVal = NIDAQYield(iYieldON);
       // Acquire data from a single channel
    iStatus = DAQ_Op (iDevice, iChannel, iGain, piBuffer, ulCount, dSampRate);
   while ((iDAQstopped != 1) && (iStatus == 0)) {
        iStatus = DAQ_Check(iDevice, &iDAQstopped, &ulRetrieved);
        iRetVal = NIDAQYield(iYieldON);
       iStatus = DAQ_VScale(iDevice, iChannel, iGain, dGainAdjust, dOffset,ulCount, piBuffer, pdVoltBuffer);
      iRetVal = NIDAQErrorHandler(iStatus, "DAQ_VScale",iIgnoreWarning);
   /* Set analog trigger mode back to initial state. */
       iStatus = Configure_HW_Analog_Trigger(iDevice, ND_OFF, iLowValue,iHighValue, ND_ABOVE_HIGH_LEVEL, ND_THE_AI_CHANNEL);
/* Set PFI line back to initial state. */
       iStatus = Select_Signal(iDevice, ND_IN_START_TRIGGER,ND_AUTOMATIC, ND_DONT_CARE);
          iStatus = DAQ_Clear(iDevice);
/* Plot acquired data */
      iRetVal = NIDAQPlotWaveform(pdVoltBuffer,ulCount, WFM_DATA_F64);
so this is the data acquired -0.900879,-0.900879,-0.900879,-0.900879,-0.900879,-0.900879,-0.900879,-0.900879 and i think that is a noise because all time i get this data.

LineChart data tip won't display with single data point?

Hi,
I have a Flex 3 LineChart with LineSeries which use CircleItemRenderer. If there is only a single data point to display, the data tip is not displayed. If there are several data points, each data tip is displayed correctly.
How can I make the datatip appear correctly with even just one data point? Any workarounds for this problem?
Quick googling found that I'm not the only person with this problem. A suggested workaround is to use PlotChart instead, but I don't want to go there unless there is absolutely no good way to solve this problem directly.

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

Plotting Data Incorrectly in a Scatter Plot

I am trying to plot a graph using a scatter plot in Numbers, and all of the data points are correct except for one. If you look at the data, you can see that the point that is at .00360 on the y axis(the highest point on the graph) is supposed to have an x value of .001 but instead it is too far to the right (closer to .1). This is throwing off my graph and I really need to get this fixed. Below are the links to the data table and the graph. Thanks for any help!

Hi Tom,
I tried recreating your table and chart, typing in the numbers rather than having any of them calculated, and manually assigning min and max values to both axes to match yours.
The chart came out with all data points where expected.
I did notice another difference in the curve though—where yours shows three data points forming a concave-toward-the-origin section (at the leftmost portion that is correctly plotted), mine shows four data points. That led me to count the points and find that there is one point—(0.139,0.00309)—missing from your chart.
While I don't see from doing this what may be wrong with your chart, it did bring a workaround to mind that should get you a useable chart before your deadline.
Insert a new (plain) table into your document and resize it to the minimum needed to hold the two columns of data.
Select the cells containing the X axis data and Copy.
Click on cell A1 of the new table and go Edit > Paste Values.
Repeat for the Y axis data, placing it in column B of the new table.
Select the data block in the new table then insert a scatter chart.
If you still get the error, manually edit the data in the cells causing the error.
That should get you through the short term. I think someone may have to look at the actual file to solve the underlying problem.

Barry

Why won't my data appear on my scatter plot graph in numbers?

I'm making a scatter plot graph and I'm dealing with very small numbers on my x-axis, such as 0.0004 and 0.184 on my y-axis. Every time I plot the scatter plot graph, nothing appears on the graph. Can anyone please help me? Thanks.

I need this graph to be black and white only but the points are blue. How do I change that?

How do you make a horizontal average line in a scatter plot?

In any version of Numbers, is there a way to make a horizontal average trendline? Not a "moving average", but one line that is the average that goes through the data points on a scatter plot.

hit a few roadblocks.
I tried:
1. using the crop tool to make the canvas bigger with a transparent background.
2. Used lasso tool over people in group shot (total of 5) and saved the selection
3. Tried content aware scale to raise the image, but it keeps stretching out the people.
Any thoughts on what else I could try?
Rather than trying to stretch it taller, try to squeeze it horizontally. There are methods for telling it what to protect in the image if it gets touchy.
Another possibility is to use Content Aware Fill to make up part at the top and bottom, without any stretching.

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:

Acquire single analog point on each pulse

Hi,
I have a query on what i hope is a simple application. Im using a PCI-6220 card and what I would like to do is aquire a single data point which is to be triggered by a digital pulse. The pulse will come from an encoder, and what I would like to do is aquire a single analog data point each time the encoder channel pulse goes high (retriggerable daq?)
Which would be the best way to approach this?
Thanks,
David

David,
this is easily done by importing your encoder-signal as external clock for your AI (which is either finite or continuous then!)
hope this helps,
Norbert
[EDIT]: This will work out directly if the encoder creates CMOS/TTL pulses. If it doesn't, you should consider some kind of signalconditioning for your encodersignal

Plotting an array with a large number of data points

Hello All,
I am collecting data every second for 24 Hrs. How do I plot this on a XY plot? I have the data collection setup in a while loop and my initial attempt was to use a shift register and a build array to make the array and that works OK. The problem is I do not know if this is a wise option in terms of memory usage. (I end up making 3 arrays and 3*86400=259200 data points in 3 shift registers).
What is the better way to plot 86400 data points in a XY plot? I am also writing the data to a file every second.
Thanks,
KB

Allan,
Thanks for the message. I am attaching with this message a ccpy of my vi where you can see that I am collecting data from 3 counters, writing them to a file and displaying them. Can you comment on this Vi with regard to memory management?
Yes, I would like to see your examples. Thanks once again.

Make trendline thicker on scatter plot?

My trendline or more specifically just the line connecting my points on my scatter plot is blue and skinny. How can I increase the thickness?

See below:
Change colour and thickness of the line/curve connecting data points:
Select the chart by clicking its icon in theSheets list in the sidebar.
Click the square in the tab indicated,
Use the stroke controls indicated to change the thickness of the line (and its colour).
To change colour and thickness of the trend line:
Click the trend line to select it.
Use the stroke controls as above. The controls will appear toward the left end of the Format bar in this case, but will function in the same manner.
In the diagram, the trend line has been set to 2 pts and a teal/turquoise colour; the connecting curve between data points has been set to 7 pts and a darker blue.

Barry

Lines in Scatter Plots?

Hello,
Well, I can't figure out how to connect points in a scatter plot with a line? Is this possible?
Thanks!
Michael Morrison

Nope, you can't, I just tried, too. With scatter, there seems to be no function to connect points in a series. Really Apple, come on. Do you want to look at a plot with 5 series on it and try to figure out which point belongs to which series? You have to be kidding me there's no way to connect them...

Your best route would be to make Text Boxes for Labels and manually position them along your X-Axis.
