No Autoscale with graphic hidden signals

Hello

I have a problem with the scales of a waveform graph. Joined a VI that illustrates this problem.

The chart is placed on a tab - control, so it is sometimes visible, sometimes not.
I feed the graph of waveform with sets of data of different wavelengths and amplitudes. For some reason I got off Autoscale. But after feeding the chart with the new data, via the property node I want the chart Auto-scale once, then I read the scales to do some calculations. If the chart is visible, everything is fine, but if the tab control - hides the graph, the balance isn't autoscaled.
What would be the trick to autoscale the graph when hidden?

Welcome, Dave

The help of LabVIEW:

Note  LabVIEW does not include hidden locations when you autoscale the axes of a chart or table. If you want to include the hidden when the plots you autoscale, make transparent hidden plots instead. Right-click the caption of the plot and select the color from the context menu to change the color of the plots.

The above probably applies to charts that do not appear, although it is not said explicitly.

As an alternative, you can:

  • AutoScale once this tab page is made visible.
  • Have another graph in a remote section of the front panel. Set to visible, but due to the size of the window, it is not in the frame. You can then copy the scales of this chart on the chart located on the tab page.

  • Problem with cursor Mixed Signal graphic LV 2013

    I'm trying to create a function that puts the cursor at a specific point on the x axis. When I send the value, the cursor behaves normally. When I send the value (even when you use a constant) the cursor will keep oscillating between the previous position and entered the property node.

    This will not occur when you use a XY Chart, only with a multi signal. Is this a bug or I'm doing something obviously wrong? Here is an excerpt of my comic.

    Hi @zumzo ,

    I understand that you have installed the driver and it works fine.  When you checked the diagnostics you became confused because it says graphic R5 but you R7.

    According to the specifications of your laptop you have AMD Quad - Core A8 - 6410 APU with graphics Radeon R5 (2 GHz, 2 MB cache).

    Here is a link to the 17-f002sm HP Pavilion Notebook product specifications to confirm this information. I hope that this eliminates any confusion.

  • Don't boot to desktop-Boot computer ups always come with "no input signal" for monitor

    Thanks for the research on this issue.  So first of all, he could start after a few attempts in the end goes to the blue screen error at approx. 5 min. I started this path several times that in "safe mode with network" to try the many suggestions of repair for two days. " At this point, it's freezing just at "windows is loading files", but probably will go to blue screen error. Boot ups always come with "no input signal" for the monitor and signal switching in the Help menu for 5 min periods I've mentioned and then fails or "monitor going to sleep" occurs.

    The error messages rec'vd: corrupted image, corrupted file and header file check sum does not match the sum of computer control. The recommendations of the screen blue: disable the BIOS memory, any material current or drivers and check disk space.

    Some tent to fix: memory diagnostics and it showed 'no problem', checked monitor on another computer and it works, in a session of 5 min a download to 'fix' Microsoft via a USB problem like "search of windows crashes" but was 'unable to set', a few other attempts would show the "windows installer has stopped working" preventing any action.

    At the present time, am unable to start even with advanced at F8 options.  It's HP Pavilion 10/2007, with the help of HP. Its on a wireless network with a netbook, Blu - ray, occasionally a cell phone that works on windows live but none presents as a device.

  • Resizing of bitmaps with Graphics.drawTexturedPath - bad ratio

    Hello

    I used to resize bitmap images (to have the similar physical size on different phones) in my project with the following code - found in this thread:

    Without creating an encoded image bitmap image resizing

        public static Bitmap resizeBitmap(Bitmap image, int width, int height)
        {
            int imageWidth = image.getWidth();
            int imageHeight = image.getHeight();
    
            // Need an array (for RGB, with the size of original image)
            int rgb[] = new int[imageWidth * imageHeight];
    
            // Get the RGB array of image into "rgb"
            image.getARGB(rgb, 0, imageWidth, 0, 0, imageWidth, imageHeight);
    
            // Call to our function and obtain rgb2
            int rgb2[] = rescaleArray(rgb, imageWidth, imageHeight, width, height);
    
            // Create an image with that RGB array
            Bitmap temp2 = new Bitmap(width, height);
    
            temp2.setARGB(rgb2, 0, width, 0, 0, width, height);
    
            return temp2;
        }
    
        private static int[] rescaleArray(int[] ini, int x, int y, int x2, int y2)
        {
            int out[] = new int[x2*y2];
            for (int yy = 0; yy < y2; yy++)
            {
                int dy = yy * y / y2;
                for (int xx = 0; xx < x2; xx++)
                {
                    int dx = xx * x / x2;
                    out[(x2 * yy) + xx] = ini[(x * dy) + dx];
                }
            }
            return out;
        }
    

    My problem with the code was that it was quite slow - larger images would take almost a second (!) on the older phones (8830) scale.  It did not prevent UI - I have the code running in a separate Thread - but it has considerably delayed showing the image on the screen.

    Recently, I started to experiment with Graphics.drawTexturedPath and I really like this method.  However, I found a weird problem while reducing images.  For example, I need to put a picture of 48 x 48 up to 42 x 42.  The most important parameters for the scale are dux and dvy (of the four walk coordinates vector only these two are zero).  So now my code object looks like this:

    XYRect area = getExtent();
    // ourBgImage is the unscaled Bitmap - our background image
    int imageWidth = ourBgImage.getWidth();
    int imageHeight = ourBgImage.getHeight();
    int[] xPts = {0, 0, area.width - 1, area.width - 1};
    int[] yPts = {0, area.height - 1, area.height - 1, 0};
    int dux = (int) ((((long) imageWidth) << 16) / area.width);
    int dvy = (int) ((((long) imageHeight) << 16) / area.height);
    // Keep aspect ratio and make image fit fully
    dux = dvy = Math.max(dux, dvy);
    g.drawTexturedPath(xPts, yPts, null, null, 0, 0, dux, 0, 0, dvy, ourBgImage);
    

    which is a little shorter and much more fast-work (especially on older phones as 8830).

    However, the image is truncated on the right and down - looks like two pixels are missing on one of these two parties.  This was not the case with the old algorithm. I am specifying all the wrong settings?

    Final nail in the coffin of drawTexturedPath:

    I decided to check how drawTexturedPath resizes checkerboard (mainly the scale down).  And the results are pretty ugly - it seems to use the algorithm "nearest neighbour" without any means.  The project with which I tested it is attached.  Once you have it running, use Alt + move to shrink and Alt + down to stretch.  Observe the results.

    The decision is, of course, to remove this method and resize Bitmaps the old way

  • Need help with graphics

    Hi all

    I'm experimenting with graphics api.

    Although I used it until I'm still not very confident on this subject. So, I want to build a strong foundation in this area. I looked online but couldn't find something really useful and what explains the basics.

    For my first mission I want to draw a rectangle in the middle of the screen. Now, for this I used a verticalfieldmanager and I replaced its sublayout method.

    In the sublayout method, I use the getgraphics() method to create the instance of the graphics class. Now, type the following lines:

    g.drawRect (width/2, height/2, 70, 30);

    g.fillRect (width/2, height/2, 70, 30);

    Super.paint (g);

    setExtent (width, height);

    but all I get is a white screen... can't use a graphical object directly in a fieldmanager? do I have to draw the rectangle in a separate field (perhaps a labelfield), then add it to the fieldmanager?

    as you can see my bases regarding the user interface graphics and custom api are not very good and that's why I need all the help I can get here.

    Thank you!!

    For one you super.paint () to call after you did you paint that will erase everything you have done. There is no need to call super.paint () If you make your own custom paint job.

  • Publish reports migration with graphic functions.

    Hi guys,.
    I'm working on the relationship between 10g and 11g migration and I have a problem with the reports that contains a chart. They give the following error when I run them against the report of 11g Server (they work very well against the server 10g with on all issues)

    The report stopped with the error:
    REP-56048: engine rwEng-1 crushed., job Id: 24.

    I searched on Google for a solution to fix them, the closer, I found was install Oracle Graphics 6i engine in a House separate from the Oracle, but this has been said for 9i and 10g, you can find that in the oracle document below:

    http://www.Oracle.com/technetwork/middleware/reports/graph-FAQ-with-style-094084.html#Q101

    Do anyone knows if I can 6i engine install Oracle Graphics in a separate Oracle 11 g House too?, so that they work at least, if not to change those that exist?

    Thank you

    Hello Sona,
    Unfortunately installation chart 6i to one OH for 11g will not work. This option is possible as long as 10g as a temporary option during migration to the BI beans new chart features in gr 10, 2 and 11 g.

    Migration Oracle Graphics graphics 6i

    How can I migrate my Oracle graphics cards to the new chart format in reports of Oracle9i or Oracle10g reports?

    Oracle9i Release 1 go, graphical reports from Oracle was desupported. Reports of Oracle9i and Oracle10g use BI beans to generate graphs. Because of the underlying technology, there is no way to direct migration of Oracle Graphics to the bean BI graphing functionality. Therefore, the user will need to rewrite all their new graphics with the graphic Wizard in Report Builder.

    Can I still use my Oracle Reports Developer 6i existing reports with graphical charts Oracle Oracle reports?

    As stated in the declaration of the Oracle reports, Oracle Graphics is no longer ships with Oracle Reports. However, as part of the migration route, you can still run Oracle Oracle reports graphic graphics if you install Oracle 6i graphics engine in a separate Oracle home. You must only maintain graph Oracle 6i as a temporary measure while redesign you your new charts using the chart wizard. For more details on configuring Oracle to use Oracle Graphics 6i, see Migration of graphics in the Oracle9i Application of Oracle9iAS version 1 (1.0.2.2.x) Server Migration manual version 2 (9.0.2).

    Can I change or add diagrams of 6i, Oracle Graphics to my reports with Oracle9i reports or reports from Oracle 10 g?

    N ° you must have a separate installation of Oracle 6i graph generator to change your existing graphic Oracle 6i graphics since Oracle Graphics is not delivered with Oracle Reports. We strongly recommend that you migrate your cards to the new standard in the Oracle reports.

  • MovieClip sprite vs drawing with graphics

    Hello! I have a program that dynamically draws a polygon anywhere where the user clicks on the screen. (using lineto, moveto) However this polygon is always behind the other symbol of objects on the screen even if his last added in the childlist is. Is there a problem with the depth when you draw symbols vs drawing with lines? How can ensure me that my smart object will display in the face?

    Thank you

    Will be

    OK the problem is that you have the graphics in the main class through the polygon class to draw

    which works great but all the objects in the main class, if they are added before or after the polygon will appear above any line draw

    to work around this problem

    change the DrawPolygon() function do not take a target

    so

    public void DrawPolygon() (x: Number, y: Number, sides: uint, RADIUS: Number, angle: number = 0): void

    adjust the call to this function in hand in the appropriate form

    then in DrawPolygon() instead of references to target just replace them with graphics this will draw on the contrary to the purpose of polygon graphics

    Note You can put calls Graphics.Clear and graphics.lineStlye early DrawPolygon() so

    We can then remove the clear and graphics.lineStyle calls in your main class

    hope that makes sense
