<p class="MsoNormal" style="margin-bottom:10.0pt;line-height:115%"><span style="mso-bookmark:_MailOriginalBody">Thank you very much for your time. Indeed, it was useful for better understand the way “Slice”+”PlotData” works by using the spreadsheet analysis.
So, apparently the only way to do a 2D plot without this issue, is to use “PlotOnIntersectionPlane” or “PlotOverLine”.<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:10.0pt;line-height:115%"><span style="mso-bookmark:_MailOriginalBody">Concerning the 2D plot along X-axis of the integrated variables along Y-axis, the simplest way to do it so far, is the method already discussed here:<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:10.0pt;line-height:115%"><span style="mso-bookmark:_MailOriginalBody">However, I wonder if Paraview developers are working on a built-in filter that allows to do that. This is a very classical analysis in aerodynamics,
so it will be widely used by the Paraview community.<o:p></o:p></span></p>

<div>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody">So, I am no expert on what you are trying to do. But, here are a few thoughts:<o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody"> <o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody">First, you don’t want to mix all five of your lines together, and just draw them through one plot data filter. ParaView won’t go down
one line, and then to the next – it will display sorted on Point ID (I think). You want one Plot Data filter for each slice/line. Attached is what I just did, for the multi-slice example. There are 5 separate slices, 5 separate Plot Data filters. I have
then turned visibility on for all 5 filters into the same chart view. I then changed the color of each filter’s Y Coordinate, so I could tell them apart.<o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody"> <o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody">What is the Plot Data filter doing? It is just going down the Point IDs, one after the other, plotting your data. Take the black line.
Point Id 0 is at u == 71.36, Y == 0.147. It then draws a line to Point Id 1, which is at u == 71.271 and Y == 0.0923. This continues through your dataset. So, the “non continuous” part of the line is where the beginning point doesn’t match up against the
ending point.<o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody"> <o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody">A good way to drill into your data is with the Spreadsheet View. Notice the highlight around the Spreadsheet View window, and that
visibility of Point Data2 is on. Also, note that you can sort this spreadsheet by clicking on the head of a column, as I did on Point ID. Now, looking at the Y’s and u’s, you can see how ParaView is drawing the chart view.<o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody"> <o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody">So, in answer to your last question, I believe you again have to deal with each line individually.<o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody"> <o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody">Does that help?<o:p></o:p></span></p>

<span style="mso-bookmark:_MailOriginalBody">All cases starts from the Delaunay 2D applied to the CSV data and in all cases I tried to plot the U-velocity vs Y-coordinate (With U-velocity shown along X-axis). As you can see, “PlotOnIntersectionCurves” and “PlotOverLine”
cases works fine: the “Uspeed vs Y” distribution is OK.<o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;margin-bottom:10.0pt;line-height:115%">
<span style="mso-bookmark:_MailOriginalBody">However the “Slice”+”PlotData” case (with a single slice) shows a bad connectivity between the points. It happens even if a refine the points cloud and even with structured and unstructured cells (Fluent CFD cases

<p class="MsoNormal" style="mso-margin-top-alt:auto;margin-bottom:10.0pt;line-height:115%">
<span style="mso-bookmark:_MailOriginalBody">Moreover, when I do multiple slices, the output array is just one single array containing data from all points merged together, so the PlotData does not allow to see each line separately.<o:p></o:p></span></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody">1) If i use one single slice, the plotted data is not a continuous line. Instead, it shows some bad conectivity between points (See
attached figure "Slice - single plane.png"). How can I solve it ?<o:p></o:p></span></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody">2) When I use multiple slice, the plotted data is merged into one single array as you can see in the other attached file ( "Slice -
multiple planes.png").However, i really need one array for every slice because this multiple output will be treated later. There is a solution for this ?<o:p></o:p></span></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="mso-bookmark:_MailOriginalBody">Concerning the second question, i remark here that making multiple "PlotOnIntersectionCurves" and then "GroupdataSets" is not a viable
option for me because I need to plot n-lines.<o:p></o:p></span></p>
