Hello everyone, sorry I'm asking what seems like a rudimentary question but I've probably spent the better half of an hour online trying to solve my problem and I have not gotten anything to work. I'm making a quiver plot with specific vectors at specific locations using the plot function:
unfortunately, my plot is what is shown below...
Those are arrows believe it or not. I can't seem to find a simple solution to making the arrow heads not so wide! My data in the x direction only varies from .6 to .7 but the x axis has been severely widened due to these wide arrows. Thank you for any help!

I think it has something to do with the values in both axes. They need to be have similar values in order for the arrows to display properly.

Hi Pablo, I'm writing regading a similar issue with the width of the arrows in the quiver plot you've got some years ago. Could you realized what was the problem?? I've tried a lot of different things but cannot make it look nice those arrows... If you know how to solve it, I appreciate any suggestion or help you can give me! Thanks!

Have you tried looking at the documentation for quiver? There is an option
In your example, you could try
and tweak scale to get what you want.

I've never come across this notation before. It doesn't seem to work. How would this code factor into actually plotting the quiver plot? I will do some searching to see if I can find an answer and will let you know if I find one if I do before you respond.

Working with Graphics Objects may help familiarize you with my use of h and the get/set interface. It certainly works in tests I have done.

Another question I have about the quiver3 plot...I'm trying to graph a vector in 3D and want to save a picture of it at a certain angle but the arrow head doesn't show up well at that angle. Can I somehow rotate the vector so the arrowhead shows up? thanks, tim

Make this a separate question and you are more likely to get an answer.
