How to add arrow at Node Points?

Hello, I am doing a finite element analysis of truss. I have plotted the truss. However, I also want to display an arrow sign at point where loads are assigned with respective directions. How do I plot it in the same figure?

Read about quiver. You can make your force a vector and plot it using quiver.

Is it available in Matlab 2018a version ?

It is a classic way of plotting vectors....it will be definitely available. It is introduced in 2006a.

You can simply try help quiver. You will get the working examples.

Thanks, It worked well. However, there a slight problem. ir seems like the size of the arrow is shown according to the magnitude of force. say i plotted 15kN and 1500kN , then at the point of 15kN, the arrrow seems to very very small(almost invisible). is there anyway to tackle the issue?

Multiple work arounds. I agree quiver is bit tedious in arrow visualization. 1. You can try specifying the arrow size. 2. You can normalise the data. 3. You can try downloading quiver codes from file exchanging.

Thanks for the information. I am also having problem creating dropdown list in a column cells in table in app designer, can you help on it? say i have four column and i want to make the entire cell in the last column to dropdown list. the row number depends on the user and can change.

No man...Iam not into that. You may post a question on this.
