xy graph Zoom

[Sena_Scott]

Hi Guys,

I have a x-y graph. Can i Check how do i zoom into the graph as (my data changes within millimeter ranges) therefore i will hope to zoom in order to view the result significantly. 

Cheers,

Scott

Hello Scott,

If you right-click on the XY Graph in edit mode and check the Visible Items>>Graph Palette selection, you should see a toolbar appear.  One of the options available there is zoom.  Refer to the LabVIEW help for more information:

LabVIEW Help: Zooming and Moving the View of a Graph or Chart 

http://zone.ni.com/reference/en-XX/help/371361K-01/lvhowto/zooming_on_a_graph_or_char/

edit- updated link to LV 2013 documentation as it's clearer, more concise, and covers more use cases.

Hi Scott,

I wonder if this is what you're looking for.

Just right click the XY Graph, select Visible Items > Graph Palette

You'll see the graph palette at the bottom of the XY Graph, as shown below

Click the middle button, and you can choose how you want to zoom the XY graph

Hope that helps.

Thanks Ongeelim,

Exactly what i wanted. Btw, i realize that my Y axis scale is 5 boxes as compared to X axis of 10 boxes. How do i make them equal? Cause it is making my circular motion into a Elliptical shape instead due to its longer time spent on the x axis. 

Cheers,

Scott

Hi Sena,

change the scaling of the axes to be the same, so your circle will be displayed as circle (when the plot area is square too)!

Hi guys, 

Thanks for the help. One additional question,if i execute a circular motion, is it possible to ensure all the points i have calculated to be on the x-y graph instead of only one point moving in a circular motion so it will be easier for the user to physically sees a circle on the graph instead of just one point moving in a circular motion.

Hi Scott,

Yes, and I believe this example provides a general idea to your question.

Oh yes guys, is it possible to have 2 inputs plotted on the x-y graph instead of only one as the current Vi only accept one input for x and y respectively.

Hi Scott,

Are you referring to placing 2 values of X and Y on single plot, or placing 2 values of X and Y on 2 separate plots into one XY graph?

Hi Ongeelim,

Placing 2 values of X and Y on 2 seperate plots in one XY graph
