I am trying to use geom_point and geom_bar but the since the geom_bar data range is different it is not seen on the graph. Here is what I have tried; point_data=data.frame(gr=seq(1,10),point_y=rnorm(10,0.25,0.1)) bar_data=data.frame(gr=seq(1,10),bar_y=rnorm(10,5,1)) library(ggplot2) sec_axis_plot <- ggplot(point_data, aes(y=point_y, x=gr,col="red")) + #Enc vs Wafer

However, it appears that the value yaxis is missing one of the the last value (I get 4 ticks for the "name" yaxis labels and 3 ticks for the "value" yaxis labels). See the following fiddle: http://jsfiddle.net/namit101/AmHhg/73/ 回答1: It does not draw 3 ticks, as you say. Axis component uses interpolation. The

This can be very fiddly, because I have to specify coordinates by hand, and, if I re-format the plot, I probably have to reposition the labels. Is there a way to automatically generate labels on curves in Matplotlib? Bonus points for being able to orient the text at an angle corresponding to the angle of the curve. import numpy as np import matplotlib

I know, that p_r_colors=copy.deepcopy(p_a_colors) for i in range(len(p_rem)): p_r_colors= np

The network trains well and predicts well on my test sets, but in order for the results to be scientifically useful, I need to be able to estimate my errors. The first step in doing this is to obtain the inverse Hessian matrix, which doesn't seem to be possible using just Keras. Therefore I am attempting to create a workaround with scipy, using

Now I want to add multiple series: I have this function: def divideAndMultiply(x,y): return x/y, x*y something like this ?: df["e"], df["f"] = df.apply( lambda x: divideAndMultiply(x["a"],2) , axis =1) It

Y-axis "1" represents percentage values, so has a Floor of 0 and a Ceiling of 100. Y-axis "2" represents monetary values, so has a Floor of 0 and a Ceiling of null . For some reason, the labels for y-axis "1" go up to 150. If I change the corresponding series data so that the value 0 is changed to 20, the problem seems to go away and the labels stop at 100 as they should. var dataX = [0, 67, 43, 100, 100, 80]; var dataY = [950, 900, 807, 650,

I have found that it is somewhere in here: Chart1 . ChartAreas [ 0 ]. AxisY . CustomLabels . Add (??????); Not sure how to get it not to have to take a double value and be able to assign a string to the point. 回答1: You have to create a custom label, set its properties, then add it to the axis What about this? CustomLabel label = new CustomLabel (); label . FromPosition = - 1.0 ; label . ToPosition =

I used the function rotx, roty, rotz to create the rotation matrix but I don't know how to use. Are these methods considering the center point as origin? 回答1: Because an image is a 2D projection from a 3D world, one of the 3D planes needs to be set to 0 if you want this to work. I'm going to assume that the z -plane is equal to 0, and so the image is laying flat on the z = 0 plane. Basically... something like this, using the cameraman.tif image. This is what it originally looks like: Here
