An image showing exactly what I said in my message.

Pretty basic stuff.

I did a xy graph to draw the data that i'm receiving, and it is working great.

But will be possible to add a balloon at the last point? 

I attached the ballon.vi that I'm trying to integrate at the graph. Is it possible?

Regards,

Vitor.

Yeah it's possible but it is a bit of a pain.  Use the PlotImages.Front property node of the graph to make an image appear on top of the graph.  You would then need to find the pixel location that the point is at using the invoke node method XY to Coordinate.  I tried this and had results that weren't great.

But an easier solution is to highlight the last point added with cursors.  Attached is a modified version that does that.

Putting the cursor I did. I was trying to change the cursor image.

Do you know where is located the cursor image at the Labview direcory, because, if I change it, it will show the new cursor style, right?

The cursor is not simply an image to be replaced.  You can select from several cursors, and line width, color, type and other settings.  

Right click the cursor in the cursor window (the thing on the right of the graph) then choose Attributes and here you can change how the cursor looks.  I suspect none of them you will like much more then the default.  The only way to do as you asked if to use the property I suggested and put the image over top of the graph.

ok,

I will see that. Thanks.

First, let's clarify that you actually have a question about your VI and not a doubt.  You don't have a doubt because you know it doesn't work.

Substituting "doubt" for "question" seems to be a very common misuse from Portuguese speaking countries. I learned how to read it correctly long ago.  I am not sure how it originates, maybe they words are used interchangeably in Portuguese. Anyone know?

I doubt anyone knows the difference.

It's something that bugs me.  I recognize it as a cultural language thing, (I tend to think it as being an Indian thing), but it a misuse of the English language.  While doubt and question have somewhat relating meanings in the sense of uncertainty, they have two completely connotations behind their usage.  "I have a question" is a very neutral "I don't know", vs. "I doubt" is a very negative "I don't believe you."  I might be tilting at windmills, but it is an attempt for the users of the word "doubt" when they just mean "question" to learn the actual meanings behind the words and start using them in the correct situations.
