LV7 How to click on an xy chart and identify the data point selected

I have an xy chart displaying a time chart showing points when faults were identified, and want the user to be able to touch the plot area and for that data point to be identified so that the main display can be switched to the appropriate data.
I have a solution where I drag the cursor to the required point then use Mouse Up event to read the cursor value, then search the data array for the matching cursor value and get the solution.
However this is on a touch screen UI and dragging to cursor does not work very well. What I would like is to be able to convert the mouse position (relative to the full screen) and convert this to the position on the plot area that is given by the cursor position.
I
f someone could tell me how to get the screen position of the plot area rather than the full bounds of the xy control I think I could do it.

Yes, I agree it is not very pratical. I would prefer if the true x,y coordinates could be obtained directly in the event structure.
In addition to the "Coords" terminal, we also need a terminal that provides the coordinates directly in the true plot units. That would definitely be very useful.
Make sure to suggest it to NI (I have, long ago!).

    my problem is : i want to display data into read mode in table control.
    but when i click on insert button on the same screen i want one blank line should inserted into table control , then i want to insert some data into table control on that row , when i click the save button . the new data inserted into the table control is insert that data into ztable ,
    please give me solution
    main problen is  how can know inserted line in table control and pass that data into ztable.

    Hi,
    Follow the below logic,
    PROCESS BEFORE OUTPUT.
      MODULE STATUS_0001.
      MODULE POPULATE_TABLE_CONTROL. --> Get the data from table store in 
                                                                          ITAB

      ENDLOOP.
    PROCESS AFTER INPUT.
      LOOP AT GT_CTRL_LP_D516.
      ENDLOOP.
      MODULE EXIT AT EXIT-COMMAND.
      MODULE USER_COMMAND_0001.  --> Here you have to take out the values from table control and update database table

  • How to convert a note in pdf and put the data in the structure SOOD4

    Good day!
    I'm using CONVERT_OTFSPOOLJOB_2_PDF.
    This function SO_DOCUMENTS_MANAGER selects a note from uploading and fills the structure SOOD4 with the file data.
    Need to do this automatically, convert to pdf and fill the structure SOOD4

    If I got your point correctly, you may use the function module SO_OBJECT_CREATE. Take a look at the thread below for an example on how to use it.

    Hi,
    You hooked up to the analog inputs on your device correctly. Thermocouples measure the difference in temperature between the DAQ and the location where the wires are welded together. They need to be insulated thermally and electrically in-between. Thermocouples have very low response compared to the normal 10 volt DAQ range. Type T is only 43 uV/C (thats 0.000043V compared to 10 volts). To see if the thermocouple is working, you need to heat up the welded end. They measure 0 V when the welded end is at room temperature. Type T only goes up to a few hundred C, so be careful, but you can probably wave a lighter under it to see if it's working. You might try the audio in on your device. You don't need a high sampling rate and it may have a better amplifier and dynamic range.
    To get absolute temperature you need to offset the thermocouple reading from the DAQ temperature (room temp usually). You could do this by measuring it with your IR thermometer. Check into the NI 9211 and simliar which are much better suited to thermocouple measurements.
    Good luck!

  • In making a monthly budget how do you repeat for next month and update the dates to the next month?

    i want to make my budget speadsheet update the month and date as it goes to the next month automatically, from sheet to sheet.  is there any way to make this happen?

    You could have a cell where you enter the month and year...
    Or you could pull the month and year from the first entry in the date column.  Like Barry I would want more information regarding your  set up before proposing any other, more specific, ideas.

  • How to show data value labels in the charts without moving my mouse on the data point?

    Sometimes I need to show a chart with data value labels which is not necessary to move my mouse on the data points. However, it seems Xcelsius does not support this simple feature. Any alternative ways?
    Many thanks!

    Currently, Xcelsius does not support display of labels at data points. It would be difficult to move and update labels on a chart with dynamically updated data. However, a work around for a static chart would be to add a Label component in the desired location. This can be done for multiple static charts by using dynamic visibility.

  • Crystal Reports - Charts - Restricting the data points on the X-axis

    Hi,
    Is there a way to restrict the number of points to display on the x-axis of a crystal chart keeping the number of data points the same.
    For example, if the chart plots date vs value points and the data for the chart is from 1980 to 2009. This means the data points on the x-axis appear very close to each other.
    I need a way to show the chart with all data from 1980 to 2009 but limited x-axis labels. Is there a way to configure the number of labels to show on the x-axis.
    Thanks!

    Thanks for the answer.
    "Right click on one of the x axis labels and select Group (X) Axis Options...
    On the Layout tab there is an option to Skip Group Labels, check this and enter in the number of labels you want to skip". Is there a way to do this from a .NET client or via a formula field in Crystal itself. The data points is going to be dynamic, hence the requirement is to dynamically configure the "number of labels" to be skipped.
    Thanks.

    ‘iPad is disabled’ fix without resetting using iTunes
    Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
    I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
    Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
    1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
    2. Open iTunes with the iPad disconnected.
    3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
    4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
    5. Click ‘Setup as new iPad’ and then click restore.
    6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
    7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
    8. The first stage in the restore process unlocks the iPad, you are basically just canceling out the restore process as soon as it reactivates the iPad.
    If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
    ~~~~~~~~~~~~~
    Try it and good luck. You have nothing more to lose if it doesn't work for you.
     Cheers, Tom

  • I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

    I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

    It's almost impossible.  The new iMacs have a Target Display Mode, but it's built to do that.  Without ripping your screen out, finding an acceptable power supply, frame, and whatever electronics to convert a Thunderbolt signal to the screen, the cost will be much larger than buying a cheaper HiDef monitor that runs with an HDMI to Thunderbolt cable to your MacBook 15.  In fact, you can sell your 17" MBP for a lot of money, unless it's broken or something, buying you a really sweet monitor.
    By the way, I found your answer by searching this forum.  I would suggest using the search function here in the futuere.
