# How to create a quiver plot with logarithmic.

Learn more about matlab, quiver MATLAB. Toggle Main Navigation. Products;. therefore the only way to properly see it in a quiver plot is if the length of the vectors will scale logarithmic instead of linearly. As far as I know, there is no built in way to do it. Manually take the log before calling quiver will not work as it will change the. scale = 2 doubles their relative length, and scale = 0.5 halves the length. Use scale = 0 to plot the velocity vectors without automatic scaling. You can also tune the length of arrows after they have been drawn by choosing the Plot Edit tool, selecting the quiver object, opening the Property Editor, and adjusting the Length slider.

As a workaround, it is possible to create a Quiver plot with arrows scaled by a known amount by turning off the 'AutoScale' option. The U- and V- data can be scaled manually as necessary to improve the aesthetics of the plot. By performing this scaling manually, a known scale. However I do not wanna the quiver in a log scale, I prefer in a normal scale. I understand ur meaning which is the shortern of the arrow may misrepresent the data, but the arrow is too long in the top half of the graph which may cause misunderstanding that the data in 100 is several times larger than 900. How to draw quiver in a logarithmic axes?. Learn more about quiver, logarithmic, semilogy. I'm looking to display the scale of my arrows on a quiver plot I've produced in relation to the plot itself. So the reader can look at my arrows and understand how they're size relate to the axis of the plot. I hope I'm being clear. Let me know if I'm not.

Thanks for contributing an answer to Stack Overflow! Please be sure to answer the question.Provide details and share your research! But avoid. Asking for. I would like to quiver the plots with time along the x-axisand include a scale which represents the 'speed' of the current. I have tried using both 'quiver' and 'quiver2' with no success. Quiver2 looks like a great function but I did not manage to get it to work. Quiver properties control the appearance and behavior of a Quiver object. Skip to content. 'on' — Scale the arrow length to fit within the grid-defined coordinate data and scale arrows so that they do not overlap. MATLAB initializes all property values before executing the CreateFcn callback.

This MATLAB function plots vectors with directions determined by components u,v,w at points determined by x,y,z. Plots matlab quiver with log scaling while maintaining proper arrows directions. 5.0. 1 Rating. 6 Downloads. Updated 15 Oct 2018. View License ×.

How does QUIVER scale the vectors it plots?. Learn more about MATLAB. The quiver3 function automatically scales the vectors to prevent overlapping based on the distance between them. quiver3.,scale automatically scales the vectors to prevent them from overlapping, and then multiplies them by scale. scale = 2 doubles their relative length, and scale = 0.5 halves them.
