I tried a variety of methods to convert the position{i} coordinates to normalized units. Start Hunting! Do you want to open this version instead? Use an automatically calculated value for the maximum y-axis limit. For axes in a 2-D view, the y-axis is vertical For axes in a 2-D view, the y-axis is vertical You clicked a link that corresponds to this MATLAB command: Run the command by entering it in the MATLAB Command Window. Enable the “stretch-to-fill” behavior (the default). y-axis direction, specified as one of these This is the function I was looking for. % input: x1,y1 - starting point line fill the position rectangle defined in the. the axes or polar axes specified by ax instead selection, the axes visibility, and the y-axis direction. Ay=[0.01 0.0060 0.0060 0.01]; Ax=Ax-mean(Ax); % center it on zero Ay=Ay-mean(Ay); Then at desired arrowhead index in on a curve vv, compute Target axes, specified as one or more axes. Set the Based on your location, we recommend that you select: . store the limit values. I can get the x/y coordinates to work but the dx/dy (3rd and 4th values in position{i}, control the slope of the arrow) are not working: Set the which displays the axes background. The options are evaluated from left to right. axis mode sets whether MATLAB® automatically Use the same length for the data units along each axis. Works great. Specifying the visibility sets the Visible axis mode establece si MATLAB ® elige automáticamente los límites o no. It also affects any legends or colorbars associated with the axes. Reverse the coordinate system so that the y values increase from top to bottom. One approach would be to define an arrowhead in the axis units: Ax=[0 -0.003 0.003 0]; % (Ax,Ay) form an upward pointing arrowhead. Greetings, I was trying to plot double arrowheads with quiver in MATLAB, with each double arrowhead pointing "inward" to the center of each node. with values increasing from top to bottom. You cannot use these options with polar axes. and ZLim drawArrow = @(x,y) quiver( x(1),y(1),x(2)-x(1),y(2)-y(1),0 ) x1 = [10 30]; y1 = [10 30]; drawArrow(x1,y1); hold on x2 = [25 15]; y2 = [15 25]; drawArrow(x2,y2) axis style uses a ... (because annotation arrows use figure units rather than axis units, the match between the arrow location and line location will be thrown off during some resizing of figures/axes, for example with manual aspect ratios). property of the Axes object or PolarAxes object to the specified value.
