Re: I change dt, but should the frequency change???
Hi, first of all you don't need to create signals in loops like you did it in your example. You can use signal generation VIs, which will do all the job for you, from Functions-Analyze-Waveform generation or Functions-Analyze-Signal Processing-Signal Generation palettes. As for your question you need to use dt LESS then 1/(200*2)=2.5 ms. This is very simple. If frequency is 200 Hz then the period of signal is 5 ms. To generate this signal you need at least 2 points corresponding to its maximum and minimum so the minimal value of dt is 2.5 ms. If you want to generate goodlooking sin wave you need more then 10 points on one period. So if your waveform has N points and corresponds to K periods (N/K 2) of the wave with frequency F then dt=(K/N)/F. Good luck. Oleg Chutko.
Re: write xy graph to png with labview 7
Hi, If you need to save the image of your control then look A HREF=http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101RPAGEID=137HOID=506500050015010100HTHREAD=65813UCATEGORY_0=_49_%24_6_UCATEGORY_S=0;here/A, where I described how to do it. There is an example which saves the image of control to JPG file. To save image to PNG file you need to replace Write JPG File.vi with Write PNG File.vi from Functions-GraphicsSound-Graphics Formats palette. Good luck. Oleg Chutko.
Re: Y axis position
Hi, if you want to show Y scale at the right side of your graph instead of its ordinary position at the left you must do the following things: Right click on the title of the scale and select swap sides option from pop-up menu. Good luck. Oleg Chutko.
Re: Hi!!how can I build a vi with every number of inputs?
Hi, one of the typical solutions is to use clusters. You can create one cluster input for your vi with many elements inside. These elements colud be of different types. With such solution you can create inside cluster much more then 28 input elements. Good luck. Oleg Chutko.

Re: How can I automatically word wrap a string placed in a (multicolumn) listbox ?
Hi, To compute the sizes of text written using some font you can use Functions-Graphics Sound-Picture Functions-Get Text Rect.vi. In this function you can specify the font name, its size, and some options (italic, bold, etc.). Good luck. Oleg Chutko.
