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.

By default, you need to turn your head to the left to read a Y axis title. When creating a second y axis, the title is oriented in the same direction as the first axis. I would prefer to reverse the text of the second y axis so that you would need to tilt your head to the right to read.

Starting in R2016a, use the yyaxis function to create charts with two y -axes. The yyaxis function has several advantages over the plotyy function. Unlike plotyy, the yyaxis function creates one Axes object with two y -axes. plotyy creates two overlaid Axes objects that can get out of sync.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.

Alternatively, we could use the following code to reverse the x-axis: #define x and y. x = [1, 4, 8, 11, 13, 14] #create scatterplot of x and y. plt.scatter(x, y) #reverse x-axis. Notice that the x-axis now ranges from 14 to 0 instead of 0 to 14. Lastly, we could use the following code to reverse both axes:In the 3D plot I need to reverse the X-axis (f) and Y-axis (K) values in reverse order. Could you please tell me how to do it? 0 Comments.
