Display Axis Lines Through Origin. By default, the x-axis and y-axis appear along the outer bounds of the axes. Change the location of the axis lines so that they cross at the origin point (0,0) by setting the XAxisLocation and YAxisLocation properties of the Axes object. Set XAxisLocation to either 'top', 'bottom', or 'origin'. In the default 2-D view, the x-axis values increase from left to right and the y-axis values increase from bottom to top. The z-axis points out of the screen. You can change the direction of increasing values by setting the associated property to reverse. For example, setting XDir to reverse, set(gca,'XDir','reverse') 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:Open in MATLAB Online.

Dear all, I want to change the x-axis direction from right to left but also keeping the values to be not affected (reversed/flipped). when I used the fooling command the mentioned problem is caused: Theme. Copy. set (gca, 'XDir','reverse') How can I solve that? This is strange. It does in my version of matlab (7.6.0.324 (R2008a)) (you can retrieve version number with the version command). If you want to place the x-axis somewhere in the middle of the picture, this is not possible in my version: the x-axis is either at the top or at the bottom (you can set this with the "XAxisLocation" property). -Axes Properties. Axes appearance and behavior. expand all in page. Axes properties control the appearance and behavior of an Axes object. By changing property values, you can modify certain aspects of the axes. Use dot notation to query and set properties. ax = gca; c = ax.Color; ax.Color = 'blue';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'.imagesc(x,y,C) specifies the image location. Use x and y to specify the locations of the corners corresponding to C(1,1) and C(m,n). To specify both corners, set x and y as two-element vectors. To specify the first corner and let imagesc determine the other, set x and y as scalar values. The image is stretched and oriented as applicable.Edited: Stalin Samuel on 31 Jan 2017.

Theme.example. stackedplot(tbl) plots the variables of a table or timetable in a stacked plot, up to a maximum of 25 variables. The function plots the variables in separate y -axes, stacked vertically. The variables share a common x -axis. If tbl is a table, then stackedplot plots the variables against row numbers.

If 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)21. Link. After your plot call, add this line: Theme. Copy. set (gca, 'YDir','reverse') See the documentation for Axes Properties for details.

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.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:The problem is, I presume, that although your image shows 15 numbers along in each axes, the total size of your image in pixels is 450 x 450 - and this is what imagesc is using..
