draw line in xy graph(picture)

[JTAG]

Hi all,

I import a picture into xy graph than i enable to annotate some indicators.

after i put the indicator in some location in xy graph(picture) i want to draw lines between the indicators.

can somebody help me with that? i'm using LABVIEW 8.2.1

sorry for my english.

Have a look at my example from long ago.

Here;s a quick and diry draft modification of your VI, see if it works for you. (lines are drawn between annotations when OK is pressed).

JTAG,

THe correct way to thank contrbutors like Christian is to give them "Kudos" by click the star for the post and if the reply if their reply is the solution then mark it as such.

take care,

Hi altenbach,

i need to create  programmatically annotation on the jpg that in xy graph can you help me with that?>

If the absolute coordinates are beyond the I16 bounds of the position coordinates (see help on Move Pen and Draw Pen), are there other choices available to draw a line on a plot?

Thanks,

Don

Whew, what monitor resolution do you have!

I doub't you'll run out of headroom in terms of pixels.

Note that we map xy (DBL, the actual values on the graph, no range limit) to coord (I32, in units of pixels, -32k to 32k).

Hello Christian -

I have posted this question in error because I tried to use the draw VI without inserting the 'Map Graph XY to Panel Coordinates' VI.  I am trying to do a programmatic draw, not a mouse draw, but this VI is obviously still required.

Glad to see you are still here.  I have left NASA in Cleveland and now am at GE Aviation in Cincinnati.  As you can see, I need to get back into the flow of things!  I have done very little LabVIEW recently - luckily it is coming back.

Sincerely,

Don
