Creating a graph from a csv-file
 
Hello,

I’m not familiar with visualization, and I never worked with ParaView before. So maybe everything I’m thinking and writing here is complete wrong.
What I want is to visualize a large amount of data that I’m creating with a program, so the output is variable and can be changed to XML or what else. At first I would like to do it in CSV-format.

The idea is to import the file in ParaView, set the options that are needed and generate a graph that can be analyzed by looking at slices, etc..

I found that this can be done with ParaView, am I right?
I did some tries with the tool, but as mentioned I’m complete new with this and maybe this task is not the right one for starting with this thing.

My data looks like this:

Table, Page-No., IUD, Program, User, Timestamp
Tab1, 123, I, Prog1, John, 2016-03-05.16.15.00.000000
Tab1, 124, U, Pog2, Peter, 2016-03-05.16.15.01.000000
….

The Table-Column holds a Table-Name (format char), Column, Page-No. ist the page-number that was updated, IUD is for Insert Update or Delete, Program stores the program-name that did the update, User holds the name of the user and Timestamp is the timestamp of the update.

These data I would like to put in a Chart and color them dependent of the UID-field. Or every User should get the same color, or program….

Basically in a 2D-chart there should be one axis for the time (x) and one for the Page-No. (y) and every dot should have a color depending on the IUD-field. In a 3D-Chart the 3d dimension could be Program or User.

So, is ParaView the right tool for that what I want or am I complete wrong?
I already tried some hours, but I guess I need some help here.

Thanks for your response
Rolf
