However using set(gca..) gives me the following error:The name 'YDir' is not an accessible property for an instance of class 'matlab.graphics.chart.HeatmapChart'.

But it does not matter:) ). The problem is that when I plot the matrix using pcolor () the matrix is ploted mirrored. An example: A= [1 0 0;0 1 0;0 0 1]; If I plot the matrix, the cell (0,0) will be plotted not in the top left corner but in the bottom left corner. (Its obvious the start of the axes is (0,0) I understand that the function is ...Flipping images is easy and straightforward in MATLAB. If you want to flip your array up to down, use flipud : udA = flipud (A); imagesc (udA) Or you can simply type. imagesc (flipud (A)) to make the image of A upside down. Similarly, to flip your array or image left to right, use. lrA = fliplr (A); imagesc (lrA)

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:

Sep 10, 2019 · Potentially easy matlab question here, but I've searched and can't sort out how to do this. I've got a variables, which plot like this: I simple want the x axis to be the y axis and vice versa. If using matplotlib you can try: matplotlib.pyplot.xlim(l, r) matplotlib.pyplot.ylim(b, t) These two lines set the limits of the x and y axes respectively. For the x axis, the first argument l sets the left most value, and the second argument r sets the right most value. Now I want to flip the y-axis so that 50 is at the bottom and 250 is at the top.

rotate(h,direction,angle) rotates the graphics object h in the specified direction by the specified number of degrees. rotate modifies the data of the graphics object, including the values of the Xdata, Ydata, and Zdata properties. This behavior is different from that of view and rotate3d, which modify only the viewpoint. example.

I need to flip just the y axis and not the image itself. I'm using the image function to plot this image, however due to the way matlab reads images, it results in the Y axis being from top to bottom. I tried using (set(gca,'YDir','normal')) but this flips the image too. Is there a way to just flip the Yaxis? Any help would be appreciated.Use the flip function to flip arrays in any dimension.. When visualizing rotated data, the coordinate system used for plotting can impact the appearance of the rotation. For example, plotting rotated data B using the command imagesc(B) followed by the command axis xy to automatically choose the x and y axes can cause the data to appear as though it was …17. To reverse an axis, you can set the 'XDir' or 'YDir' property of the current axes to 'reverse': set(gca,'XDir','reverse'); %# This flips the x axis. Keep in mind that flipping an axis in this way flips everything in the plot as well. This probably isn't what you want to do for the y axis. You probably just want to flip the y axis labels ...Jan 24, 2014 · Commented: Iain on 24 Jan 2014.
