Update: giving a much more thorough example. The first two solutions offered were right along the lines of what I was trying to say not to do. I can't know location, it needs to be able to look at the whole document tree. So a solution along these lines, with /Books/ specified as the context will not work: SELECT x.query('.') FROM @x...
I'm trying to make a plot with pylab/matplotlib, and I have two different sets of units for the x axis. So what I would like the plot to have is two axis with different ticks, one on the top and one on the bottom. (E.g. one with miles and one with km or so.) A picture says more than a thousand words. Something like the graph below (but ...
How can I flip the origin of a matplotlib plot to be in the upper-left corner - as opposed to the default lower-left? I'm using matplotlib.pylab.plot to produce the plot (though if there is another plotting routine that is more flexible, please let me know). I'm looking for the equivalent of the matlab command: axis ij; Also, I've sp...
I am drawing a graph using the plot() function, but by default it doesn't show the axes. How do we enable showing the axes at x=0 and y=0 on the graph? Actually my graph is something like: And I want a horizontal line corresponding to y=0. How do I get that? ...
Hey everyone, This is my first post here and since I've seen many great answers I thought I'd give it a try. I'm trying to use XPath to obtain a specific element in an HTML document. Here is an example based off of the Google web page: <html> <head> <title>XPath Test</title> </head> <body> <form name='f'> <table> ...
Hey, I have a matrix A which I am plotting using imagesc(A). The matrix is a 512 X 512 matrix, but I need the axes to be labeled from 0 to 4000 instead of 0 to 512. I can't seem to find where I can change this instead of just changing from where to where the points are plotted! ...
I would like to edit the axes in my series of images being displayed. This is what my image looks like: As you can see, it ranges from 0 to about 500 from top to bottom. Can I invert that? Plus, I want to mirror the image being shown, so that it starts from left to right... or, if it's possible, to let the axes show from right to lef...
Suppose I have a figure canvas with 3 plots... 2 are images of the same dimensions plotted with imshow, and the other is some other kind of subplot. I'd like to be able to link the x and y axes of the imshow plots so that when I zoom in one (using the zoom tool provided by the NavigationToolbar), the other zooms to the same coordinates, ...
Trying to plot a spectrum, ie, velocity versus intensity, with lower x axis = velocity, on the upper twin axis = frequency The relationship between them (doppler formula) is f = (1-v/c)*f_0 where f is the resulting frequency, v the velocity, c the speed of light, and f_0 the frequency at v=0, ie. the v_lsr. I have tried to solve ...
Is there an easy way to remove a plotted line from a set of axes without clearing everything else on the axes? I'm trying to implement a GUI with a listbox containing several data sets. I can make the callback function plot the selected data, but I'm not sure how to 'unplot' it when I deselect a data set. Any ideas? ...
Hi, I'm trying to retreive the previous node in a for-each using the preceding-sibling axis, a filter and an indexer to find it. The problem is, I only want the first item that matches the XPath in the selector however, I seem unable to apply both the filter and the indexer. The indexer seems to override the filter so I always get the ...
I've got a GUI in MATLAB with a set of axes pre-placed. I'm using the location property of the legend to place it to the right hand side of the axes. However, by doing this the axes get re-scaled so that the axes+legend take up the original width of the axes. Is there any way to circumvent the re-size? Example: x=0:.1:10; y=sin(x); fi...
Most MATLAB plotting commands allow you to specify which axes to act on, for instance plot (x,y) plots in the current axes, but plot(Ax, x, y) will plot in the axes Ax. Similarly, you can label the x- or y- axis of a non-active axes xlabel(Ax, 'this label goes on the x-axis of Ax whether or not Ax == gca') But the text comman...
How do I obtain all the axes handles in a figure handle? Given the figure handle hf, I found that get(hf, 'children') may return the handles of all axes. However, the Matlab Help suggests that it may return more than just the axes handles: Children of the figure. A vector containing the handles of all axes, user-interface objects di...
