QUESTION
This example code gives me everything I want except for the colorbar labels.
...ANSWER
Answered 2021-Jun-06 at 17:38Not a perfect solution but maybe it fits your needs:
- To show the endpoints add
show.limits=TRUEas I already suggested in my comment. - To get rid of the intermediate labels I make use of a custom labeller function. This function is called two times by the scale. Once for the default intermediate breaks (which in almost(!!) all cases is a vector of length > 2) and once for the limits (which is a vector of length 2). Hence I check for the length of the passed vector and keep only the labels for the "limits". But keep in mind that this is only a kind of heuristic which may fail in extreme special cases.
QUESTION
from my knowledge, Power Spectral Density (PSD) should stay relatively constant with the total time sampled (or aka. N-points sampled), however I have having trouble obtaining this result.
As I know from Discrete Fourier Transform (DFT), the amplitude normalization is 1/N. (e.g Amplitude Spectrum = DFT/N). However, from various sources, the PSD is defined as (DFT * DFT-conjugate / N).
How can this be possible? It is true that the Amplitude Spectrum has a 1/N normalization constant, then shouldn't the PSD have a 1/N^2 normalization constant (since DFT is proportional to N and so is its conjugate).
More specifically, I am trying to calcuated the PSD of a continuous electric field wave using the Eq. 9 of this paper. However I can't make sense of it's constants infront of the DFT since the factors of N's cancel out leaving behind only the summation of the window function squared. I tested this result and found that the PSD does not stay relatively constant with sampling size.
In summary, I have having troubles since my PSD varies with the amount of total time of the signal sampled. Any help would be great, thanks!
...ANSWER
Answered 2021-May-27 at 03:29I've found the PSD of a time-series does increase linearly with the number of points sampled, N, however, an appropriately FITTED function (or some sort of averaging) allows the PSD to remain constant with N. One would then take the PSD at a point on this fitted function.
This is a direct result of conserving the area of a curve, AKA Plancherel's theorem.
QUESTION
I am trying plot 8 ggplot objects with ggarrange such that it plots 4 ggplot objects in each row. The code works fine, but now I am wanting the plot to be plotted in a way that the the plots occupy the extra white space between the label and the plot, for example the plot occupies the white space between label A and that plot, and so on for the rest of the plots. Basically, I want to stretch the plots, so all the space available in the grid is used. How can I do this?
ANSWER
Answered 2021-May-12 at 07:36I found another way to reduce the margins, i.e. to minimize the space between the plot label and the plot itself. What I did was that once ggarrange displayed the plots in the plot section of RStudio.
I clicked on on the Zoom button, and the plots then got displayed in a popup window, which showed the plots with reduced space between the labels and the plots. And I believe, this can be further modified by adjusting the size of the popup window.
I used this approach, because I had a lot of plots in ggarrange, and one of these plots contained a raster with thousands of pixels, so each time I tried something different with the code, ggarrange took a lot of time, thus reducing the performance of my computer.

Answered 2021-May-11 at 11:15The response from @Mr.T is really helpful!!
Use f-string formatting plt.title(f'PSD: power spectral density for {columns}')? You probably will also benefit from getting familiar with subplots and axis objects. – Mr. T
QUESTION
I have a stacked bar chart in Chart.js 2.9.4.
On hovering, the tooltip's tip is positioned at the top-center of each bar, but the tooltip itself is rendered to the right and blocks the view of other bars.
I'd like to draw the tooltip above the bar. Is there a way to do this?

If I have an image in the form of [556,556] PX and I would like to plot a certain range of them so say:
Image Size: [556,556]
Plot -> XPixels [224,300] YPixels [224,300]
This was my attempt and it does sort-of what I need it to do, I have the correct pixels selected but unfortunately this only labels the given range and doesn't actually plot the range. Understandably the next part of this would be to plot the new range given the image but how would I go about this?
