阅读更多关于 How to change legend size with matplotlib.pyplot

问题 Simple question here: I'm trying to get the size of my legend using matplotlib.pyplot to be smaller (i.e., the text to be smaller). The code I'm using goes something like this: plot.figure() plot.scatter(k, sum_cf, color='black', label='Sum of Cause Fractions') plot.scatter(k, data[:, 0], color='b', label='Dis 1: cf = .6, var = .2') plot.scatter(k, data[:, 1], color='r', label='Dis 2: cf = .2, var = .1') plot.scatter(k, data[:, 2], color='g', label='Dis 3: cf = .1, var = .01') plot.legend(loc

IMAP command to get size of message

阅读更多关于 IMAP command to get size of message

问题 I am looking for the best way to get the sizes of messages using IMAP(i am writing a simple c# lib for myself). Basically a POP3 STAT command equivalent would be good, but it does not exist. I am thinking of fetching the message header and getting the content-length field. Anyone got a better idea or solution? 回答1: Perhaps using the FETCH NNN HEADER is the only way of doing that. Have you checked the spec for FETCH NNN RFC822.SIZE ? Also perhaps a good idea would be to learn from fetchmail

阅读更多关于 Overriding setPreferredSize() and getPreferredSize()

问题 Due to the answers I have received I am now doing this a different way. Is there any way to override setPreferredSize() and getPreferredSize() so it will actually set the size of the component to a number higher than was actually input, and get a number that is a number lower than it actually is? Here I am overriding both methods to set the size of a panel to 100 pixels more than what I actually put in setPreferredSize() and if I were to get the preferred size, I would like it to return what

问题 Is there a limit on a value string in php Associative array? I have a query that returns value of GROUP_CONCAT as CSV for an array element.

admob adsize for ad height

阅读更多关于 admob adsize for ad height

问题 I am aware of the different values that the admob size can take for example 'BANNER' which is 320 x 50, however I have seen in some apps that the ad has been made smaller, in particular squashed in height. I have tried using other values instead of 'BANNER' for adsize but it does not work. How can I make a admob banner with a lower height than 50? THanks! 回答1: you will never get an admob banner below 50px. If you try to put it in a layout below 50px it will register an error (check your
