connecting only wanted points in analysing xy graph

[touheed]

hello NI thanks in advance for the team support 

firstly i am getting a force velocity characteristic on an xy plot and from this graph iam geeting peaks plots on another graph. Now problem is i want to store only these peaks points in an file another file. and to import these peak data from stored file And main thing to do is during the analysis of this imported data i want to draw line between these points. ( not all points but only those which iam interested in)

hope my explation is clear.

How do you determine which of the points you want to connect?

You just need to create a second set of data that only contains those points and plot that as a second plot.

thanks for your quick reply 

your point is true there is no relation along those points.

and your second solution really works

but one more thing how to import the data to xy graph?
and also another problem can we change the colour of xy graph during the run via some swith 
coz actually i am plotting force velocity graphs on xy plots and i wnt that if i change velocity it should change plotting color of xy graph. is this possible ?

thanks in advance

Look at the example for XY graphs to see the different methods of combining multiple series on a single graph.  Usually it is something like an array of clusters.

To change colors programmatically, you will need to use property nodes.  Look at setting the active plot property, then writing a color to the Plot.Plot Color property.

thanks for bro 

how to change the what number we need to use
