• Display of the image without covering the circle behind

  Dear all,

  I have a great difficulty to display an image without covering the 'circle' behind. I have a circle in the center of the screen. The circle is the circle of draw by draw .vi. After a while, a table is displayed in the Center. But the circle behind is still required to demonstrate. I used playback .jpg, etc... to display the image. When the image is on, however, it covers the 'ring '. I can't do it in re-trace the circle on top of the image due to timing because of the sensitivity of the search. Could you please provide suggestions? Thank you very much!

  How about two indicators of photo?  One on the top that contains the circle but otherwise has a transparent background.

  The indicator of the photo that you draw your other image is backward in your z-order of the controls on the front panel.

• Draw the circle on MapView

  Hi all.

  I am quite new to the development of the Cascades.

  I would like to know if it is possible to trace a circle on a plan, given a Point and a RADIUS.

  I searched a bit on the doc, but I not only found ways to draw polygons from a set of coordinates.

  IIRC the fact maps app exactly that, show GPS accuracy of the signal (IE put a circle around you on the map to show the accuracy of the coordinates).

  Thank you very much, greetings

  Thanks BBSJdev, but I need an overlay following cards (and with a dynamic dimension) and not static.

  In any case, I found a nice way to draw a circle-layer on the mapview. Here is the code:

  It is an improved version of the solution that someone else posted on this forum some time ago (which did not perfectly, as she draws an elypse and not a circle). I can't find this post now, in any case I would like to thank the user who wrote this snippet.

  Here is the code:

  void ApplicationUI::drawCircle(double lon, double lat, double radius) {    MapView *mv = root->findChild("mapView");    DataProvider *dp = mv->mapData()->defaultProvider();
  
      // convert radius meters to latitude width    double latr = radius / 111412.84; // this is the number of meters per degree
  
      // with longitude it's a bit more complicated, since a degree of longitude 's length    // is not constant (unfortunately the earth is not flat)    int a = 6371000; // earth radius in meters    double rad_lat = 0.0174532925 * lat; // convert latitude from degrees to radiants    double _lr = ((M_PI / 180) * a * cosf(rad_lat)); // length of a degree of longitude in meters    double lonr = radius / _lr;    qDebug() << "lonr = " << lonr << " ; _lr = " << _lr << " ; latr = " << latr << " ; lat = " << lat;
  
      GeoPolygon* result = new GeoPolygon;    Polyline line;    const int numOfSeg = 36;    for ( int i = 0; i < numOfSeg; i++ ) {        double theta = 2.0f * 3.1415926f * float( i ) / float( numOfSeg );        double x = lonr * cosf( theta );        double y = latr * sinf( theta );        line.append( Coordinate( y + lat, x + lon ) );    }
  
      result->setOuterBoundary( line );    result->setId("id-circle");    mv->mapData()->defaultProvider()->add(result);
  
  }

• Since Apple ridiculously decided to abandon the center of games tab of my friends in the game does not load automatically and I have to go to GC and click the circle of friends so he could load, MORE I wonder constantly if I want to use my game stored loc

  Since Apple decided to abandon the center of games tab of my friends in the game does not load automatically and I have to go to GC icon and tap the circle of friends so he could load several times, MORE we continue to request if I want to use my game stored locally or my stored GC game. I refuse to install iOS 10, because it means of course I won't be able to manually load the tab my friends and my losing my game completely. How can I fix it? Remove the Center game is the worst thing that Apple could have done, in my humble OPINION.

  You will not lose your game entirely. I have several games of game Center, and they work fine. And I understand the developer of a game that this game center continues to store the backup of your game.

  It's just that now friending is handled via the interface of the game. The only options that you have in iOS10 is to go to the settings panel in / log out of game center or remove all friends. And none of the games I play has updated so I can see how their friending works with iOS10.

  Beyond providing the basic interface, Apple seems to have turned all aspects of the social game on the games themselves.

• Where is the Circle of Friends on iWatch?

  Just downloaded new iWatch update, and not the circle of friends used to send messages or texts went. Ho you get your contacts to send texts, etc.?

  Hello

  Under watch OS 3, the friends functionality, which was available in previous versions, comes more and there is no direct replacement for it.

  When making calls or sending of new messages, contacts instead can be selected via the phone and Messages applications or using Siri:

• Why can I not see videos from YouTube without the circle in the middle of the screen rotation?

  Whenever I try to watch a movie or a video clip, the screen keeps stuck and the circle in the middle of the screen keeps spinning.

  Sorry for this late reply, but your answer to my problem was exactly what I need! I looked at my films and documentaries since you gave me your suggestion and they are just as good, if not better.

  Thank you SOOO much!

  It indicates that the phone is locked in portrait mode. Swipe to the bottom of the screen to call the control center. Tap the corresponding icon there to allow rotation in fashion landscape.

  Hello all, I had been defrauded of online recruitment last 3 months ago and already reported the case to the authorities.

• How to trace the greatness of the variables compared to the timestamp with evenly spaced samples in time?

  Hello world. I need to trace the variable amplitudes compared to the timestamp (date and time), but the time intervals between samples are not equidistant. In my area, this is called trend plot. I'm surprised that Labview does not a vi to do this. The only solution that I found so far is to save the data in an Excel file and open this chart in Excel because it has the ability to trace what that this is against what whatsoever is not limited to something as even spaced samples. How to achieve this is Labview? A graph of waveform vi would be perfect if it was not by the fact that it works with even spaced samples.

  Thank you.

  Paulo Siqueira

  Your requirement is directly possible with LabVIEW.

  You can spend time to understand the difference between 'Chart', 'Graph' and "Graph XY".

  VI attached is drawing samples of unequal time.

  Hint:-right click on the 'XY' graph-> properties-> display-> 'Axis of X' = absolute time Format

  Kind regards

• How to trace the signal acquired against the clock all the time fixed by using Graph XY?

  Hello

  My goal is to trace the signal acquired against the clock all the fixed time dynamically. In General, it is like trace the waveform of the signal against the clock in a graph, but don't keep the recent 10 min waveform. My current approach is to get the timestamp by a VI and the express VI to use XY graph to make the plot. The result keep all data in the history which is not what I want. My question is that how to achieve my goal?

  Thank you very much

  Hao

  One way to show the last ten minutes of data is to use a graphic instead of a graph. Set the size of the history of the ranking for the number of samples you acquire in ten minutes.

  If you want to use the graph XY, you will need to manipulate the data yourself. If you don't want data from the last ten minutes and you want to throw all the old data, set up a circular buffer sized to hold the ten minutes of data. Once the buffer is full (after the initial ten minute break) adding a data point removes the oldest point. Make the buffer of a 2D with X data table in a line and the data Y in the next line. A queue with loss can be used in recent versions of LV to implement a circular buffer. In older versions, a driving force would be a good choice.
