I have a step function plot in matlab. I want to reverse the y axis so that the initial value is at the top and also the x axis start from that point only. 21. Link. Open in MATLAB Online. After your plot call, add this line: Theme. Copy. set (gca, 'YDir','reverse') See the documentation for Axes Properties for details.The image function reverses the y-axis so I wanted to reverse it to correct it. I know it has something to do with gca but cannot figure out the right code. Please help me.

In order to flip the labeling of the y-axis while keeping the matrix plot unchanged, you can use the " set(gca, 'YDir', 'normal')" or " set(gca, 'YDir', 'reverse')" command after plotting your data with " imagesc" function. This command changes the direction of the y-axis without altering the data in the matrix.Plot Data Against Left y -Axis. Create axes with a y -axis on the left and right sides. The yyaxis left command creates the axes and activates the left side. Subsequent graphics functions, such as plot, target the active side. Plot data against the left y -axis. Get. x = linspace(0,25); y = sin(x/2); yyaxis left.

Copy. set (gca, 'YDir','reverse') See the documentation for Axes Properties for details.So when viewing cell C as the coordinates in the 2D space, the vertical axis (the column) is z and the horizontal axis (the row) is v. And the value f(v,z) is built up on these coordinates. So one can imagining plotting a 3D picture. Then I fill matrix M, which contains the value of f(v,z) according to the cell C.

Link. Hello Giorgia, 'fplot' is mostly used to plot a curve defined by y=f (x) where 'x' is input and 'y' is output which is the standard convention. I would recommend you use a simple 'plot' function since you will get control over how you want to represent the data in the plot. Refer to the following documentation for more details:Matlab用imagesc函数画图时，一般将图像矩阵的起点 (1,1) 画在左上角，如果该点代表的实际位置是物体的左下角，那么Matlab所画的看起来就是倒立的图像，因此需要翻转Y轴。. 以下介绍几种方法可以实现这一功能：.

I have data where the origin is the top left hand corner and want to preserve that y measurement rather ... Display Axis Lines Through Origin. By default, the x-axis and y-axis appear along the outer bounds of the axes.Change the location of the axis lines so that they cross at the origin point (0,0) by setting the XAxisLocation and YAxisLocation properties of the Axes object. Set XAxisLocation to either 'top', 'bottom', or 'origin'.Set YAxisLocation to either 'left', 'right', or 'origin'.

I tried adding: set(h2,'YDir','reverse'); But that results in the following error: The name 'YDir' is not an accessible property for an instance of class 'lineseries'.Open in MATLAB Online. That is a bug that has been fixed in R2019a (and perhaps earlier). The only workaround seems to be to create separate 'YTickLabel' strings with spaces to the right to offset them from the y-axis: Theme. Copy. figure; plot (gca,0:2); set (gca,'XDir','reverse') yt = get (gca, 'YTick');One of the sequences goes on the bottom, the other goes on top (from top to bottom), and the y axis is split into two (half for the bottom bars and half for the top bars). The bottom bars use one color, like green, and the top bars use another color, red, and the y axis uses the respective colors on each half on the axis. Example:
