Call it df : A B C 0 1 2 3 1 1 2 3 2 1 2 3 3 1 2 3 4 1 2 3 Now let's say I have a function f(A,B,C) , which in theory would take columns A , B , and C as inputs. For example, def function(A,B,C): return (A+1, B/2, C*3) This function returns a tuple, of course. Essentially, I'd like to know if I could apply function to df to get the following output: A B C 0 2 1 9 1 2 1 9 2 2 1 9 3 2 1 9 4 2 1 9 If so, how would I do that? I can't just type df

I would like to draw the rectangles in the same svg. However only one set of legend is being added. Only the first json data is drawn as rectangles. The second is ignored. My code is : svgcheckins = d3 . select ( "#legend" ). append ( "svg" ). attr ( "id" , "svgcheckins" ) . attr ( "width" , 250 ) . attr ( "height" , 200 ) . append ( "g" ) . attr ( "transform" , "translate(" + margin . left + "," + margin . top + "

I'm trying to create a line chart with the X-axis labeled marking the year change (ie: 2005, 2006, 2007, etc). The data is made up of readings taken daily, so it would not be possible to indicate each one, but breaking them down by year seems very reasonable. I'm struggling to figure out how to do it, though. So, instead of... X-axis __________________________________________________________________________________ 2000-01-01 to

It works for a single axis on a single plot. When running it in a subplot() structure, it only works on the first plot when I apply it to the final plot. The modification I am looking for are these: 1: How to make it work on subplots. I tried calling JavaScript in the build of each subplot, but all plots came out without exponential then. 2: make it work for both x an y axis (I tried, failed and cried a

I need to have a second x-axis on my plot and I want that this axis has a certain number of tics that correspond to certain position of the first axis. Let's try with an example. Here I am plotting the dark matter mass as a function of the expansion factor, defined as 1/(1+z), that ranges from 0 to 1. semilogy(1/(1+z),mass_acc_massive,'-',label='DM') xlim(0,1) ylim(1e8,5e12) I would like to have another x-axis, on the top of my plot, showing the corresponding z for some values of the expansion factor. Is that

I'd like to be able to create a custom x-axis with the following ticks on it for each year: 1) at 1/1 have the YYYY (ie 2011 ) 2) at 4/1 have the abbreviation of the month (ie Apr ) 3) at 7/1 have the abbreviation of the month (ie Jul ) 4) at 10/1 have the abbreviation of the month (ie Oct ) Here's a description of the data: > head(as.POSIXct(rs4p[,3])) [1] "2008-06-30 20:00:00 EDT" "2008-06-30 20:00:00 EDT" [3]

This pipeline is intended to be used by engineers with no 3D math experience. Commented out are the X and Y axis rotation matrices that produce the exact results they should . The Z rotation matrix seems to do nothing.

I have it programmed to set to landscape mode but the x and y axis seem to be the oppisite between the 2 devices. The x axis returns 10 when held perpendicular to the ground and the Archos X axis returns 0. The Elocity tablet is android 2.2 and the Archos is 2.1. Can someone point me in the right direction as how to get orientation from the accelerometer in sync between these 2 devices?
