I have images that I want to show in axes and work on them using the Image Processing Toolbox with gui and pushbuttons. Sometimes the images are bigger than the axes.

Therefore, if the image is bigger how can show a fitted version inside the axes while keeping the same aspect ratio and run the IPT on this "fitted" version? Accepted Answer. Image Analyst on 15 Oct Cancel Copy to Clipboard. Use imshow. It will auto-size the image to fit the max space you allowed for the axes while keeping the aspect ratio the same. Lluis Roca on 16 Oct Hi, Thanks.

I always use imshow. Image Analyst on 16 Oct Documentation Help Center. Specify the limits as vector of four, six, or eight elements. For example, specify the style as equal to use equal data unit lengths along each axis. Specify the mode as manualautoor one of the semiautomatic options, such as 'auto x'. The y values increase from top to bottom. The default for ydirection is xywhich places the origin at the lower left corner.

The y values increase from bottom to top. Plots in the axes still display. The default for visibility is onwhich displays the axes background. For 3-D axes, it also returns the z -axis limits. For polar axes, it returns the theta -axis and r -axis limits. This syntax will be removed in a future release. Specify ax as the first input argument for any of the previous syntaxes.

Use single quotes around input arguments that are character vectors, such as axis ax,'equal'. Create a stairstep plot, and use the axis padded command to add a margin of padding between the plot and the plot box. Create a plot. Set the limits for the x -axis and set the minimum y -axis limit. Use an automatically calculated value for the maximum y -axis limit. Starting in Rb, you can display a tiling of plots using the tiledlayout and nexttile functions.

Call the tiledlayout function to create a 2-by-1 tiled chart layout. Call the nexttile function to create the axes objects ax1 and ax2.Sign in to comment.

Commented: Ahmer Shahid on 13 Jan Accepted Answer: Star Strider. I am trying to make it so that the all the images I show in an axes fill the axes completely, no matter the size of the image. Accepted Answer. Star Strider on 25 Aug Vote 1. Cancel Copy to Clipboard. See the documentation for axis for details. Ok so the width of the images isn't changing, however the height of the images is still moving even with the axis image implemented after every image.

You can set the height and width for all of them to be the same by adding 'XData' and 'YData' to the imshow call:. Experiment with those values until you get the result you want. Note that changing the aspect ratio with these will distort the displayed image. My pleasure! Stelios Fanourakis on 23 May Star Strider. Thanks a lot Star Strider.Sign in to comment.

Rotating an entire axes in Matlab Guide. Kribashnee Dorasamy on 26 Feb Vote 0. Commented: Jan on 27 Feb I am currently trying to rotate an entire axes named axes1. The code above initiates a rotation of 30 degrees.

However, the image is rotated but not the entire axes1. I have tested guide tools such as the rotate3D, however rotate3D does not work successfully for 2d images.

Resizing images by inbuilt commands and our own matlab program

Vote 1. This works fine:. But this produces a warning and an empty plot:. The warning is:. Images that have a range close to fold makes the plotting command behave strangely:. More precisely, when I run the following code in Matlab, it does what I expect it to do: It displays the Mandrill although upside down and in wrong colors, but that is not the point. I asked Matlab to scale the x-axis logarithmically and I asked it to display the Mandrill so that the center of the leftmost pixel is over coordinate 0.

This is also the result I get. On the other hand, when I run the following piece of code, the results are not what I expect. Building on the experience of the previous code, I would expect to see the same mandrill, this time with the scale on the x-axis ranging to This is not what I get on my computer.

Instead, I get an empty plot and this warning:. Now why is this?Matlab Fit Image To Axes. Thanks a lot for your response.

Actual measurements between individual products may vary. It then removes the axes title as well as the axis labels and tick labels for each axis, allowing the axes to fill the figure as much as possible. To create a plot with a linear scale on the x-axis and a log base 10 scale on the x-axis you can use the function semilogx. This feature makes representing a matrix with imagesc is far easier than with image. Then, whatever you draw using this second axes will be referenced to the secondary y-axis.

The example. Setting the aspect ratio and axis scale: The axis command enables you to adjust the aspect ratio of graphs. It's somewhat confusing so let's make an analogy.

I only added data centering to further improve performance. I want to set an image as the background of Matlab GUI. This is needed article for me. The general form of the command is: axis 4. What i have to do to plot the image at the center of the axes for. The easiest way to do this is with the axis image command.

We trained more than students to develop final year projects in matlab. Best Elliptical Fit for irregular shape. Here is a way to read files without a header. New imwritefloattiff. You need to use the axes object and then. The first is the X values of the points to plot, and the second is the Y value of the points to plot. When i am clicking the button at the first time the image is plotted correctly at the center of the axes,but at the second time the loaded image is plotted at the right side of the axes only.

The next part, theta xmust be a function that we're using to fit the data. You need to use the axes object and then use imshow to show your image.
