I have already tried set(gca,'Ydir','reverse') before posting this question here. But unfortunately, I am not able to get my desired result. Moreover, when I am using X=-x to flip the x axis, the axis values become negative and I am unable to change them to positive x-axis values.

Add another sine wave to the axes using hold on. Keep the current axis limits by setting the limits mode to manual. y2 = 2*sin(x); hold on. axis manual. plot(x,y2) hold off. If you want the axes to choose the appropriate limits, set the limits mode back to automatic.In this code, we plot the video and eye position separately to adjust the y-axis limits of both plots to match the reversed y-axis of the eye position data. Then we plot them together using imshow for the video and plot for the eye position, with the hold on and hold off commands to combine the plots. We also adjust the y-coordinates of the eye ...Accepted Answer. You can change the direction of increasing values along the y-axis by setting the YDir property of the Axes object.

Try. set(gca,'YDir','normal'); answered Oct 30, 2013 at 23:09. …Description. example. imagesc(C) displays the data in array C as an image that uses the full range of colors in the colormap. Each element of C specifies the color for one pixel of the image. The resulting image is an m -by- n grid of pixels where m is the number of rows and n is the number of columns in C.To change direction of y axis, including axis labels and plotted values, you use. set(gca,'YDir','reverse') When you plot an image, for example using imagesc, the YDir property is automatically set to reverse. So, to change it, set it to normal: set(gca,'YDir','normal') edited Dec 25, 2013 at 20:25. answered Dec 25, 2013 at 19:33.I have multiple things plotting on one graph and have one of the axes on the right side and the other two on the left.

To plot two sets of data with separate x - and y-axes, create two separate axes objects in a tiled chart layout.Within one of the axes objects, move the x-axis to the top of the plot box, and move the y-axis to the right side of the plot box.. For example, you can create two plots that have different x - and y-axis limits.. First, create two sets of x - and y-coordinates.This property controls where MATLAB displays the y -axis tick marks and labels. Setting this property to right moves the y -axis to the right side of the plot from its default position on the left side. See the plotyy function for a simple way to use two y-axes. Properties That Control the X-, Y-, or Z-Axis.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. x = linspace(0,25); y = sin(x/2); yyaxis left. plot(x,y);

subplot (3,1,3) % now plot but put y on x axis instead... plot (y,x) set (gca,'ydir','reverse') % reverse the y axis to match view. title ('Two argument plot & reverse yaxis') The above produces--. Note the last two are identical and that all it takes is using both an x,y vector in plot.

If you want to reverse a function you may use flip function: Theme. Copy. x = linspace (0,10); y = sin (x); x = flip (x); % reverse the values of x. plot (x,y) If you want to reverse the axes then here is an example code which you may use: Theme.The first row of pixels is normally at the top of an image. By default, the IMAGE and IMAGESC functions invert the y-axis direction when the image is displayed on an axes by setting the 'YDir' property to 'reverse.' To invert the y-axis direction, set the 'YDir' property to 'normal', as follows:Edited: Stalin Samuel on 31 Jan 2017. Open in MATLAB Online. If you planning to change the ylabel use. Theme.

Modify Properties of Charts with Two y-Axes. The yyaxis function creates an Axes object with a y-axis on the left and right sides.Axes properties related to the y-axis have two values.However, MATLAB ® gives access only to the value for the active side. For example, if the left side is active, then the YDir property of the Axes object contains the direction for the left y-axis.plot(x,y) Add another sine wave to the axes using hold on. Keep the current axis limits by setting the limits mode to manual. y2 = 2*sin(x); hold on. axis manual. plot(x,y2) hold off. If you want the axes to choose the appropriate limits, set the limits mode back to automatic.Look at the y-axis: Here it starts from 1.00 and ends at -1.00. Conclusion: By using invert_yaxis() method we can reverse the y-axis of the plot. Read Put legend outside plot matplotlib. By using ylim() method. ylim() method is also used to invert axes of a plot in Matplotlib. Generally, this method is used to set limits for the axes.plot(x,y) Add another sine wave to the axes using hold on.

We can use these to set the format of the x-axis using datetick. The two axes have to be set to the same values otherwise you'll get weird overlapping text, and it seems datetick will only handle one axis at a time, hence a loop: for n = 1:2 datetick(ax(n),'x','dd-mmm'); endInverse Y axis with negative values. Hello, I would like to plot 3 negative values with the plot in the vertical direction and not inverted.
