Feb 15, 2022 · 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. Here's an example of how the plot titles currently look: Oct 31, 2020 · Why to have to resort to such trickery instead of just being able to set the axis direction for the axis of choice like any other graphic axis is beyond the pale, however. This recent penchant (that seems to only be accelreating with time) to create these black/dark-gray graphics objects is just totally misguided im(ns)ho. From your question I infer that you want to set the x-axis labels from -180 to 180, and the y-axis labels from -90 to 90. To do this, you should change the XTickLabel and YTickLabel properties of the axis object (note that you'll also need to adjust the number of ticks in each axis by modifying the XTick and YTick properties accordingly).. So, assuming that your image is stored in the matrix ...

Learn more about parallel plot, y axis, reverse direction Hi all, I have plotted a parallel plot in Matlab. But I want to reverse the direction (means min value at the top and maximum at the bottom) of a particular Y-axis in that plot?By default, Matlab has positive x-axis backwards, y-axis toward left side and z-axis toward upward direction (as in the attached picture). While maintaining the right hand coordinate system, I would like to switch the axis such that z-axis is positive downwards, x-axis toward right side and y-axis toward forward direction.I would like to make a heatmap from tabular data. My code is below. The heatmap has y-axis values descending order, I would like to them in ascending order. 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'.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:.

Reverse y-axis, so lower values are nearer the top. "xy" Restore y-axis, so higher values are nearer the top. If the first argument hax is an axes handle, then operate on this axes rather than the current axes returned by gca. See also: xlim, ylim, zlim, daspect, pbaspect, box, grid, caxis.

Create axes with a y -axis on both the left and right sides. Plot a set of data against the left y -axis. Then, use yyaxis right to activate the right side so that subsequent graphics functions target it. Plot a second set of data against the right y -axis and set the limits for the right y -axis. x = linspace(0,10);

Other kinds of subplots and axes are described in other tutorials: 3D axes The axis object is 'scene'. Polar axes. The axis object is 'polar'. Ternary axes. The axis object is 'ternary'. Geo axes: The axis object is Geo. Mapbox axes. The ...Description. B = flip(A) returns array B the same size as A , but with the order of the elements reversed. The dimension that is reordered in B depends on the shape of A: If A is vector, then flip(A) reverses the order of the elements along the length of the vector. If A is a matrix, then flip(A) reverses the elements in each column.Jun 9, 2010 · Get a Free Trial: https://goo.gl/C2Y9A5Get Pricing Info: https://goo.gl/kDvGHt Ready to Buy: https://goo.gl/vsIeA5 http://blogs.mathworks.com/videos This MAT... Since Matplotlib v3.1 there is also the set_inverted method on an axis. The advantage of this over the invert_[xy]axis used in the accepted answer is that you get the same result regardless of how many times you call it. I.e. invert_[xy]axis reverses the current direction whereas set_inverted(False) makes it increasing and set_inverted(True) makes it decreasing.I'm trying to recreate a matlab plot I've come across in some other work, but I don't quite understand the scale they are using. The y axis increments are as follows (from the top [+ve y]): 0.9999, 0.999, 0.99, 0.9, 0. I can use semilogy to plot a logarithmic graph, but this is kind of the wrong way round; my increments go. 1, 0.1, 0.01, 0.001, etc

Additionally I want the reversed y axis plot to be a bar graph and the other to be an ordinary line plot. @Learnaholic it covers two images together in the same figure (in your case it is the same aMatrix image). ax1 is the figure handle that the y axis is set on the right, when you imagesc the image for 2nd time, you first get the axes info before imagesc. The position of the 1st image is obtained via get(ax1,'Position').Set the yticks using the values in y and modify the yticklabels of the right y-axis accordingly - If the order of labels is expected to be reverse of that is displayed below, flip the variable str to reverse the order .

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.Modify Properties of Charts with Two y-Axes.

Here's an example of how the plot titles currently look: Hi i'm looking for a synatix or function that rotates a plot, e.g if i have a peak that is a minimum, is there a way to flip it upside down and make it a maximum? (bareing in mind the peaks are ... 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. @Learnaholic it covers two images together in the same figure (in your case it is the same aMatrix image). ax1 is the figure handle that the y axis is set on the right, when you imagesc the image for 2nd time, you first get the axes info before imagesc.

You can use the function flip to flip any array along one axis: Aa = flip(A,2); This will work for both a gray-scale and an RGB image. This is equivalent to the following indexing expression for a 3D array (such as an RGB image): Aa = A(:,end:-1:1,:); Tip: If you are going to write a loop, always make the inner loop the one that loops over ... plot(x,y) Add another sine wave to the axes using hold on.
