Graphs

[harisskriss85_85]

Hallo,

       I have a 2D array with 5 rows and 5 columns. Each element represent a variable. I have a control for the row number. For a given row number each variable seeks a value from the DAQ system and the five elements of the row are plotted over time. When I change the row number, I need the graph to start freshly for the new row number, but instead it continues with the new values. Please find attachment for Reference.Please help. Thanks in advance.

Hi hariss,

when you use a graph: you need to clear some buffers in your VI…

when you use a chart instead of graphs: clear the history!

Hallo Mr.GredW,

          Thanks for the reply. I have a time stamp for the variables which are plotted on the X-Axis. Can I still use the chart instead of Graph as you mentioned. I would be glad if you can help in this. Thanks

Hallo hariss,

it depends on how you provide your data to your chart/graph. Attaching a VI would help to understand your problem…

Hallo hariss,

the interesting part is the missing "plotdata_2012.01.10" subVI…

In any way you are using a XY graph. So all you need to do is clearing internal buffers when switching the rake!
