managing plot legends at run time

[user_1]

Hi,

I have a graph for multiple plotting.

There are buttons on the front pannel to make the plots visible/not.

Is there any way to make the appropriate plot legends to make visible or not in accordance with the plots visibility?

Now if the user selects to see 3 plots then also it shows all the plot legends instead of three.

Thanks....

Use a property node of Graph called 'Legend:Plots Shown' to vary the number of plots to display in plot legend

Thank you so much for your reply.

My problem is there are totally 10 plots.

Suppose user wants to view only 3.Then in graph there are 3 plots.But Plot legends 10.

If I am using the property node u specified,is it possible to achieve that?

The user may be selecting plot2,plot 6 and plot 9.

Then the legends shown should be plot2,plot6 and plot9 only.

Thanks once again

Well, here is a vi that can serve as a pointer with respect to the property nodes that can be of use for your requirement

After you make the plots visible/invisible, redefine the Legends: Plots shown and rename the displayed plots

Thank you so much sir.

Thanks for the information.

But still i have something to disturb you again.

If i am viewing random plots will it be ok?

ie,after the user runs the appln,all the ten plots will appear.Nw if he is going to view only 3 plots,it may be any 3(from 1 to 10) by switching off the other 7

will there be any problem?.

Hi user_1,

As long as you know the order of the remaining plots and can name them accordingly, this method should work just fine for arbitrarily disabled plots.

That is,

1   Disabled
2   ****
3   Disabled
4   ****
5   Disabled


If you know that 2 and 4 are the remaining plots, name the plot legend accordingly after you have resized it to 2 elements with Legend:Plots shown.

Best regards,
