问题 I have to translate an image plotting script from matlab to matplotlib/pylab, and I'm trying to achieve the same effect as the matlab image below: As you can see, the z order of the plots seem to be higher than the z order of the grid, so the markers are not hidden by the axes. However, I can't figure out a way to do the same with my matplotlib image: I'm wondering if it is possible to get the same display without having to increase the limits of the y axis. 回答1: To get the marker to show

问题 I'm attempting to use a custom scale/axis transformation, like so: library(ggplot2) library(scales) dat <- data.frame( time.tot = c(407.17, 168.83, 127.8, 108.88, 69.04, 68.5, 59.76, 407.17, 168.83, 127.8, 108.88, 69.04, 68.5, 59.76, 407.17, 168.83, 127.8, 108.88, 69.04, 68.5, 59.76), error = c(0, 0.01, 0.05, 0.1, 0.5, 0.7, 1, 1.91e-06, 0.00229, 0.00884, 0.0172, 0.128, 0.128, 0.22, 1.43e-08, 0.000337, 0.00121, 0.00221, 0.0123, 0.0123, 0.0213, 0, 0.01, 0.05, 0.1, 0.5, 0.7, 1, 1.91e-06, 0.00229

How do I swap tensor's axes in TensorFlow?

由 荒凉一梦 提交于 2019-12-17 18:17:23
问题 I have a tensor of shape (30, 116, 10) , and I want to swap the first two dimensions, so that I have a tensor of shape (116, 30, 10) I saw that numpy as such a function implemented ( np.swapaxes ) and I searched for something similar in tensorflow but I found nothing. Do you have any idea? 回答1: tf.transpose provides the same functionality as np.swapaxes , although in a more generalized form. In your case, you can do tf.transpose(orig_tensor, [1, 0, 2]) which would be equivalent to np.swapaxes

Can I mimic a log scale of an axis in matplotlib without transforming the associated data?

问题 I am trying to display a Zipf plot, which is typically displayed on a log-log scale. I'm using a library which gives rank in linear scale and frequencies in log scale. I have the following code which plots my data fairly correctly: ranks = [3541, 60219, 172644, 108926, 733215, 1297533, 1297534, 1297535] # These frequencies are already log-scale freqs = [-10.932271003723145, -15.213129043579102, -17.091760635375977, -16.27560806274414, -19.482173919677734, -19.502029418945312, -19

MATLAB how to get mouse click coordinates

由 爱⌒轻易说出口 提交于 2019-12-17 16:35:48
问题 I have made my GUI using GUIDE. I have an axes (tag=axes1). An image is displayed in the axes. When i click on the image(inside axes) I need to get the coordinates. I get the coordinate values when image is not added to axes.But image is displayed in axes do no obtain the axes. How to get the coordinates? 回答1: Let's assume that you've plotted the image with handle imageHandle that: imageHandle = imshow(imageObj); You should assign the ButtonDownFcn to the image handle not the axes handle that
