Matlab reverse y axis.
Description. barh(y) creates a horizontal bar graph with one bar for each element in y. If y is an m -by- n matrix, then barh creates m groups of n bars. barh(x,y) draws the bars along the vertical axis at the locations specified by x. barh( ___,width) specifies the fraction of available space occupied by each bar.
Location of y-axis tick marks and labels. 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-AxisIf you do print(fig) you’ll see that the yaxis is already reversed (this is the default of px.imshow in order to display image data, that is the origin is at the upper left corner). You could do. fig.update_yaxes(autorange=True)Open in MATLAB Online. You can change the direction of increasing values along the y-axis by setting the YDir property of the Axes object. If you want the values to increase from bottom to top (2-D view), then set the value to 'normal'. Alternatively, if you want the values to decrease from bottom to top, then set the value to 'reverse'.how to reverse the axis in matlab??. Learn more about revesing axis MATLAB
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:

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'.
Many thanks for your reply. 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.
Issue and Question. I encountered that my graphics are all upside down.Now I have to mirror them in pgfplots.How can I perform this step?

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.You have flipud in the call to set the YTickLabels, which may mean you are assigning the wrong tick labels to each tick (essentially assigning them in reverse order).Try commenting out the second line (the one that is setting YTickLabels) and see if it looks like the ticks are in the correct order.If so, remove the flipud. Change Axes Properties. Modify properties of a chart with two y -axes by setting Axes properties. Create a chart with two y -axes and plot data. Reverse the direction of increasing values along each y -axis. Use yyaxis left to activate the left side and set the direction for the left y -axis. Changing horizontal axis to descending order. Hi all. Do anyone know how to change the order of xaxis labels in the plot function? Instead of, say, 1 , 2 , 3... i would the axis to plot for ..., 3, 2, 1. Thank a lot,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:Axes Appearance. You can customize axes by changing the limits, controlling the locations of the tick marks, formatting the tick labels, or adding grid lines. You also can combine multiple plots, either using separate axes in the same figure, or by combining the plots in the same axes, with the option to add a second y -axis.
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.

Properties That Control the X-, Y-, or Z-Axis.Simply reverse the order of the "axis" command and the "plot" command. When you use "axis" before "plot", "plot" overrides the "axis" command with default axes. Switching these two lines will fix the problem. However, if you want to animation individual points, there is also a "set" command which works wonders for neat animations. Check this out:
As J.M. pointed out, ContourPlot[x^2 + y^2, {x, -5, 5}, {y, -50, 0}, ScalingFunctions -> {"Reverse", "Reverse"}] will reverse both axes. If you'd only like one axis reversed, you can replace one of those "Reverse" s with Automatic. Thank you!! It was so easy :) A used just one "Reverse" i thats why it didnt work.

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.The problem, as you can probably see in the image, is that setting the Ydir-property to 'reverse' does not change the direction of the y-axis, but what happens is that Xdir is set to 'reverse' and the axis locations are changed to 'right' and 'top', and not even explicitly setting them to 'left' and 'bottom' moves them to the right place.The axis labels are also consequently in the wrong place.
