axis

I'm building a bar plot in d3.js in which each bar represents total TB cases during a month. The data essentially consists of a date (initially strings in %Y-%m format, but parsed using d3.time.format.parse) and an integer. I'd like the axis labels to be relatively flexible (show just year boundaries, label each month, etc.), but I'd also like the bars to be evenly spaced. I can get flexible axis labeling when I use a date scale: var xScaleDate = d3.time.scale() .domain(d3.extent(thisstat, function(d) { return d.date; })) .range([0, width - margin.left - margin.right]); ... but the bars aren't

I have a following array. a = np.array([[0, 5, 0, 5], [0, 9, 0, 9]]) >>>a.shape Out[72]: (2, 4) >>>np.all(a,axis=0) Out[69]: array([False, True, False, True], dtype=bool) >>>np.all(a,axis=1) Out[70]: array([False, False], dtype=bool) Because axis 0 means the first axis(row-wise) in 2D array, I expected when np.all(a,axis=0) is given, it checks whether all element is True or not, per every row. But it seems like checking per column cause it gives output as 4 elements like array([False, True, False, True], dtype=bool) . What am I misunderstanding about np.all functioning? user2357112 axis=0

The error is: Exception occurred while reading or writing file {0}The Axis2 facets cannot be installed since the Axis2 runtime location has not been set. Go to the Web Services preference page and set the Axis2 runtime location under Axis2 Preferences. In the preferences mentioned, the location is set correctly and in fact, it says "Axis2 runtime loaded successfully" after loadign the correct runtime location. So what's going on? Any solutions other than re-installing eclipse or creating a new workspace? I am using Axis2 1.4.1 and eclipse. Re-check your axis version used with Eclipse (to be
