Graphviz is the

问题 Context I want to plot two ggplot2 on the same page with the same legend. http://code.google.com/p/gridextra/wiki/arrangeGrob discribes, how to do this. This already looks good. But... In my example I have two plots with the same x-axis and different y-axis. When the range of the the y-axis is at least 10 times higher than of the other plot (e.g. 10000 instead of 1000), ggplot2 (or grid?) does not align the plots correct (see Output below). Question How do I also align the left side of the

问题 I'm trying to show some data about Australian suburbs. 'Suburb' is the term that Australians use to describe an area, if you are from the rest of the world think post code or something similar. I'd like to be able to get access to the area boundaries that are already in the map. These are examples of the kind of boundary that I'm talking about: Marrickville, Sydney (2204): http://goo.gl/maps/QYRhx Clapton, London (E5): http://goo.gl/maps/3an2Y I want to be able to draw the boundary on the map

问题 I have a date field in my DimDate table. I want to get another column WeekOf that would show the week number based on Monday. For example I have date: Date WeekOf 10/2/2017 Week of 2nd 10/9/2017 Week of 9th 10/16/2017 Week of 16th 回答1: Creating a new column with the following formula should give you what you want. If you every want to change it to be the Week of a different day, change the 2 in the TargetDate variable to which ever day of the week you want. WeekOf = VAR TargetDate = DAY

问题 This question already has answers here : Extract arbitrarily rotated plane of data from 3D array as 2D array (2 answers) Closed 4 years ago . I have a 3D stack of bwlabeln'ed data (128 by 128 by 128). Is there a way to cut a slice through it (as in MATLAB slice(...)) and save the resulting image to a matrix? Thanks in advance! 回答1: the function that may be of use is: http://www.mathworks.com/matlabcentral/fileexchange/32032-extract-slice-from-volume for other solutions, see: Extract

问题 I have 2 lines in the form of waves plotted in x-y axis based on randomly generated data and i am showing circles on the waves denoting the data points on it. Based on setInterval of 200 ms , I am updating the original data and the lines(waves) are moving to the left, but the issue is that the only circles which are there in the initial interval are moving and for 2nd interval onward the circles are not showing up on the waves. see the jsfiddle for the running code : https://jsfiddle.net

问题 I want a scatter plot of different types of "asset", each asset should have the same color and labeled in the legend. I can do this using an NdOverlay of Scatter. Then I want to overlay two such plots, eg one coming from a model and another from experiment, so that the first and second only change in marker but keeps the same color for each asset. I would expect this to work df1 = pd.DataFrame({"asset": ["A", "B", "B"], "x": [1,2,3], "y": [1,2,3]}) df2 = pd.DataFrame({"asset": ["A", "B", "B"]
