Just curious why the more clumsy expression seems to give "better" result. 回答1: First of all, here is scipy.nanmean() so that we know what we're comparing to: def nanmean(x, axis=0): x, axis = _chk_asarray(x,axis) x = x.copy() Norig = x.shape[axis] factor = 1.0-np.sum(np.isnan(x),axis)*1.0/Norig x[np.isnan(x)] =

I used xlim(0,155) it showed the histogram all across the screen but it override the ticks I defined. 回答1: The problem is that xlim(0, 155) is actually a shorthand for scale_x_continuous(lim = c(0, 155)) . Therefore, when you use both, xlim() and scale_x_continuous()

The figure looks ok, with the exception of the minor ticks from the secondary y-axis (right) being also displayed on the primary y-axis (left), on the inside of the figure. import matplotlib . pyplot as plt from mpl_toolkits . axes_grid1 import host_subplot import mpl_toolkits . axisartist as AA host = host_subplot ( 111 ) host . set_yticks ( np . arange (- 12 , - 3 , 1.0 )) par1 = host . twinx () par1

I generated Java files from WSDL with WSDL2Java converter, but I don't know how can I use service with these files, because there are no examples. I'm implementing client side. Regarding Axis2: read these these links they contain some examples: http://ws.apache.org/axis2/1_5_1/quickstartguide.html#clients http://ws.apache.org/axis2/1_0/userguide3.html EDIT: Regarding Axis1: it is based on JAX-RPC and you need to instantiate stub object or use service locator to get stub instance and all WS operations will be in that. An example is given here : public class Tester { public static void main

Basically, I defined the class Transform to use an object QMatrix4x4 as argument for the transform field of the QML Item class Transform : public QQuickTransform{ Q_OBJECT Q_PROPERTY(QMatrix4x4 matrix READ matrix WRITE setMatrix NOTIFY matrixChanged) public: explicit Transform(QQuickItem *parent = 0); QMatrix4x4 matrix() const; void setMatrix(QMatrix4x4 matrix); virtual void applyTo(QMatrix4x4 *matrix) const; signals: void matrixChanged();

When I see the output from the Accelerometer Sensor, I see If I don't use any filter, (Case : I kept my cell phone idle on table) I get z Axis +ve value. Now If I think using basic physics, it gives me exact value(9.8approx) for small g i.e Acceleration due to gravity. To get the linear acceleration, If I add any force to phone it will change the Accelerometer value, but it will be g + a that I applied. So to get a why can't I just

I have made my own tickFormat function myTickFormat and use that in .tickFormat([format]) and that works fine because [format] is expected to be a function. But it is not possible to do the same with .innerTickSize([size]) , which expects a number. E.g. if I want the tick at value 70 to be longer I want to do something like this: var myTickSize = function(d) { if (d === 70) { return 20;} return 6; }; But when I use myTickSize

Here is a SSCCE of the problem with random numbers as the live input. The time shown on the x-axis is much faster than real-time (assuming it is shown in hh:mm:ss format): public class DynamicTimeSeriesChart extends JPanel { private DynamicTimeSeriesCollection dataset; private JFreeChart chart = null; public DynamicTimeSeriesChart(final String title) { dataset = new DynamicTimeSeriesCollection(1,

Of course I could use a smaller font or rotate them a little but I would like keep them vertical and readable. As an example: df here the x axis is just letters, but if I want to use the full name, the names use a disproportionate amount of space: plot + theme ( axis . text . x = element_text ( angle = 90 ))+ scale_x_discrete ( breaks = unique ( df_M$variable ), labels = c ( "Ambystoma mexicanum" , "Daubentonia madagascariensis" , "Psychrolutes marcidus" ))
