The upper graph has data coming in as individual scalars, but the data coming out of the collectors feeding the bottom graph are single element arrays. When you feed scalars into the graph it will plot point-to-point, but when you feed an array into the graph it ASSUMES it contains all the points you want to plot in one shot. When a new array comes in, the plot is cleared and the new data is presented.</FONT></SPAN></DIV><DIV><SPAN class=250230106-22112004><FONT face=Arial color=#0000ff size=2></FONT></SPAN> </DIV><DIV><SPAN class=250230106-22112004><FONT face=Arial color=#0000ff size=2>If you want them to look the same, take the XEQ pins from the three COLLECTOR boxes and attach them to the bottom of the FOR COUNT box. Now when you run it you will get nothing on the bottom box until the very end, THEN you will get the entire array plotted in point-to-point style just like the top array. (As a side note, it's faster to plot this way then plotting one scalar value per loop.)</FONT></SPAN></DIV><DIV><SPAN class=250230106-22112004><FONT face=Arial color=#0000ff size=2></FONT></SPAN> </DIV><DIV><SPAN class=250230106-22112004><FONT face=Arial color=#0000ff size=2>Cheers,</FONT></SPAN></DIV><DIV><SPAN class=250230106-22112004><FONT face=Arial color=#0000ff size=2>Mike Groves</FONT> </SPAN></DIV><BLOCKQUOTE dir=ltr style="MARGIN-RIGHT: 0px">  <DIV class=OutlookMessageHeader dir=ltr align=left><FONT face=Tahoma   size=2>-----Original Message-----<BR><B>From:</B> Antti.Suhonen@elektrobit.com   [mailto:Antti.Suhonen@elektrobit.com]<BR><B>Sent:</B> Sunday, November 21,   2004 10:38 PM<BR><B>To:</B> VRF<BR><B>Subject:</B> [vrf] Re: what's   it?<BR><BR></FONT></DIV>  <DIV><FONT size=2><FONT color=#0000ff><FONT face=Arial>Hi   all,<BR><BR>Erm...Sorry about the delivery, its the head   ;p</FONT></FONT></FONT></DIV>  <DIV><FONT size=2><FONT color=#0000ff><FONT   face=Arial></FONT></FONT></FONT> </DIV>  <DIV><FONT face=Arial color=#0000ff size=2>OK, here's again.
