How can I increase line width on polar plot?

The lines plotted on a LabVIEW 6 polar plot (picture control) are very thin and do not show up well when printed. I would like to increase the line thickness (as can be done easily on the graph controls), but looking through the polar plot VIs, I cannot find any obvious way of doing this.

The polar plots basically use the picture control to draw the lines on a plot. To increase the thickness of the lines you would have to draw another line right next to the line. I'm sure this could be done, but would require alot of messing about with the drawing subVI's to draw all lines in duplicate.
Alternatively you could plot the graph twice, but the second plot has an origin 1 pixel out. This will double the thickness on the screen, but i dont know what it will print out like. See attached example in LV 6.0.
Another thing to try is change the plot colours. You can make the gridlines black (instead of grey), and paint the background white. This makes the lines show up much better. I will also include this in the same example.
I hop
e this helps you..

  • How can I set Line Width

    Hello,
    When I print a PDF document with a 3D annot in "Illustration" Mode, I've got a bad printing. All lines are too thin and sometime hidden.
    Is it possible to set the line width? where? in U3D doc or directly in pdf3d engine ?
    I apologize for my bad english.
    Thank you for answers

    I do not think it is possible in U3D - there seems to be no field setting line width in the U3D spec.
    As to the "pdf3d engine" - likely no. I was complaining on this forum about similar problem with point size
    (it can not be controlled and was changed from 1 pixel to 3x3 pixel in a new version of Reader)
    and got the following reply from a man of Adobe (http://forums.adobe.com/message/1922684#1922684):
    We try to adhere as closely as we can to published formats,
    so as point size is not supported in U3D it is not displayed in Acrobat.
    We have much greater influence over the content of PRC, so we can more quickly make improvements to that format.
    The size of the points displayed by U3D was changed
    - but as U3D does not support point sizes, it is not part of the U3D supported elements.
    It seems lines and points parts of U3D spec are less important to Adobe than meshes,
    so many features are not supported (some limitations are documented, some not).

  • How can I increase the width of the 'mail composer' box and put the attachment box (at present on the right) below it?

    The width of the 'mail composer' box is too narrow so that with my email program half the buttons are missing.
    == All the time

    Thanks for your swift response.
    I understand the difference between the web browser and email program.
    I have just started using Firefox from IE and IE displayed the new mail page full width.
    Firefox displays the reading web page full width but not the compose mail page because of the layout with the attachment box to the right of the box where you write your mail.
    I was hoping that there was a way to customise and change the layout.
    Is that possible?

    When using large text my lines overpal, how can I increase the line spacing?

    Press 'Ctrl + Enter' after the numbered item to insert blank space below it. If you press 'Enter', the next line will start with the next number. As long as you want to type lines without a numbering, press 'Ctrl + Enter' and type the line.

  • How can I increase the storage capacity in Linux for installing Oracle 11g?

    Hi all,
    I've been searching in Internet information about how to increase the storage capacity of a Linux machine, so that it can help me with my problem without success. I tried to execute some command lines encountered in some tips in forums, but no one works.
    I want to install an Oracle 11g database, which needs 4 GB minimal for the installation. I can not continue with the installation because of this problem.
    I use a VMWare virtual machine, which I increased over its settings to 160 GB, but not its file systems or whatever in the machine.
    I did this:
    [root@localhost ~]# df -h
    Filesystem Size Used Avail Use% Mounted on
    /dev/sda3 18G 15G 1.9G 89% /
    /dev/sda1 190M 12M 169M 7% /boot
    none 506M 0 506M 0% /dev/shm
    /dev/hdc 699M 0 699M 100% /media/cdrom
    As far I understand the bigger storage capacity is used by the file system /dev/sda3. But what about the rest, I mean the 140 GB?. I've already increased the storage capacity over the settings. How can I tell the machine "please use the remaining 140 GB for the installation of the Oracle DB and other needed installations?.
    How can I increase here what?. Disk? File system? Volume Group? It can not be so difficult, can it?
    There are no volume groups in the machine:
    +[root@localhost /]# vgdisplay+
    +No volume groups found+
    Linux is too complicated. Unfortunately I have to do that in Linux :-(
    Can someone help me? I sit here since long hours without finding a solution :-(

    thanks for your answers.
    To Dude:
    You can address the problem in a number of different ways, but please post your version of Linux and provide more information about your current partitions
    The Version of Linux is Linux Red Hat Enterprise 5.
    Open Logical Volume Management from the System Administration menu.
    Select your volume from the logical view, edit properties and then use the slider to set your volume size, or click "remaining" to extend your partition.
    I've already opened the LVM from the System Administration menu, but there is no possibility to see the volume groups, because there is no one. There is no tabs like Volume Groups or something like that...
    I would try the procedure described above your answer and write you again. I hope it works...I will write you back in a few minutes...

    Do you mean "Recent Tags" which has an icon a blue-colored folder with a primitive looking magnifying glass over the folder?
    That folder does have a limit of 10 results. If you want to create an "All Tags" item on the Boomarks Menu, you can do that by creating your own "smart folder." The process I use is a little involved, so bear with me (also, see the screen shots).
    The query used by Recent Tags is:
    place:type=6&sort=14'''&maxResults=10'''
    So for All Tags we will drop the maximum results limit:
    place:type=6&sort=14
    ''If you prefer your tags in alphabetical order instead of having the most recently used at the top, use this instead:''
    place:type=6&sort=1
    Go ahead and select the line you want and right-click > copy it.
    Next, click the bookmarks drop-down button, expand the Bookmarks Toolbar, right-click any existing item, and choose New Bookmark.
    In Location, paste the query, and in name, type All Tags (or your preferred description). When you click Add Bookmark, Firefox will add it, but it doesn't show the blue search folder icon. Drag the bookmark to the menu, and it will turn into a functioning search folder.
    Success?

  • How can I sort lines of data (alphabetically) in the new pages 5.0?

    How can I sort lines of data (alphabetically) in the new pages 5.0?
    It was very simple to do in the previou version of pages.

    I'm not sure why people are torturing themselves with Pages 5 given the nearly universal outcry on this forum and the incredibly negative reviews elswhere, such as the App Store.
    Pages 4.3 should still be in an iWorks folder within your Applications folder.  Just use that.
    Please remember to tell Apple what we need from them at:

  • How can I increase resolution when saving file as PDF?

    I am sending some illustrated files to a professional printing press that only accepts PDFs, however they say the resolution is too low and should be 300dpi. How can I increase resolution? Only option I could find was to try to create a new filter in Color Sync by duplicating PDFX3 filter and editing it to the desired resolution, however I couldn't get new filter to save my resolution inputs. Any help is appreciated!

    You really need something like Acrobat which will install a "Save as Adobe PDF" under the PDF menu. You can select press quaility," "high quality print," etc., and get a true high res PDF.
    If you'd like to just give it a shot, try downloading one of the OS X CS6 suites that include Adobe Acrobat Pro for a free 30-day trial. I've never used SketchBook Pro, but Acrobat may help you out.

  • HT4863 How can I increase the file size limit for outgoing mail. I need to send a file that is 50MB?

    How can I increase the file size limit for outgoing mail. I need to send a file that is 50MB?

    You can't change it, and I suspect few email providers would allow a file that big.  Consider uploading it to a service like Dropbox, then email the link allowing the recipient to download it.
