How can I change the values dislayed in the top right corner of matplot figure? By default it is showing coordinates of the current cursor position but I'd prefer it to show the value of displayed data for current x cursor's coordinate. I marked these values in the attached picure. diagram
Here's a simple code. Pls tell me how to solve described problem for this example:

QUESTION
I know how to use inline keyword to avoid 'multiple definition' while using C++ template. However, what I am curious is that how linker is distinguishing which specialization is full specialization and violating ODR and reporting error, while another specialization is implicit and correctly handle it?
From the nm
output, we can see duplicated definitions in main.o and other.o for both int-version max() and char-version max(), but C++ linker only reports 'multiple definition error for char-version max()' but let 'char-version max() go a successful link? How linker differentiate them and does this?
ANSWER
Answered 2022-Mar-21 at 00:02However, I start to be curious why nm gives different marks on Cygwin than on Ubuntu?? and Why linker on Cgywin can handle two T definitions correctly?
You need to understand that the nm
output does not give you the full picture.
nm
is part of binutils, and uses libbfd
. The way this works is that various object file formats are parsed into libbfd
-internal representation, and then tools like nm
print that internal representation in human-readable format.
Some things get "lost in translation". This is the reason you should ~never use e.g. objdump
to look at ELF
files (at least not at the symbol table of the ELF
files).
As you correctly deduced, the reason multiple max()
symbols are allowed on Linux is that the compiler emits them as a W
(weakly defined) symbol.
The same is true for Windows, except Windows uses older COFF
format, which doesn't have weak symbols. Instead, the symbol is emitted into a special .linkonce.$name
section, and the linker knows that it can select any such section into the link, but should only do that once (i.e. it knows to discard all other duplicates of that section in any other object file).
QUESTION
I'm using the matplotlib backend 'notebook', because I am making some interactive figures, and this works well with the notebook backend (in particular, I serve them via Jupyter Notebooks). I use ipywidgets to design the GUI and interactivity.
However, using this backend, there are all sorts of buttons that can interfere with my interactive figure. Especially, resizing, zooming, panning, or the power button, will lead to much confusion for my students...
I want to disable them. See this illustration on what I want to disable.
Can anyone point me to the relevant API pages or does anyone know how to disable/remove these buttons? I tried some other backends, but these typically will not work so well for interactive figures in Jupyter notebooks, so I want to stick to the notebook backend if possible.

Answered 2022-Mar-15 at 16:12You need to include information about the sigma
information of each Gaussian. When you say percentage coming from each population, I think you are asking about the total counts (integral) in each Gaussian. For a Gaussian in your form, the integral is:

...ANSWER
Answered 2022-Mar-14 at 10:28The main problem is that you never redraw the canvas, so every change you communicate to matplotlib will not appear in the figure generated by the backend. You also have to update the properties of the rectangles representing the bars - you tried this with bar.set_color()
in one of the versions which changes both facecolor
and edgecolor
, intended or otherwise.
QUESTION
I am trying to build an app that lets the user to upload an excel file, choose a worksheet and some data (i.e column) and make graphs.
I have prepared a dummy app to show my probelms. I have two of them...
- The update of the input for the worksheet name is not working. Althogh the input field is updated by
updateSelectInput
it always rewrite to the default value (I think there is a nesting issues but I try to solve it for more then two days, without any luck...) - I don't know how to set the input of the worksheet to be able to receive any name later, now it always jumps back to the first WS (If I set
choices = c('')
orchoices = 1
it gives an error that there is no such WS)
ANSWER
Answered 2022-Mar-10 at 23:32I added more than you asked for to try and solve this, so I hope the extra steps are helpful or insightful. I also don't have xlsx
since I don't have java, so I used openxlsx
instead.
I can spot a few issues with your current code. For example, your reactive has an observeEvent in it, which observes the ws_var
input, and is meant to update the worksheet names based on when a worksheet is selected. It might work better if you observed the xls_input
instead.
What I provided may be a bit more robust. I added show/hide features using shinyjs
, seeing as each step is dependent on the previous step. Meaning the following step will only show when the previous is selected. Additionally, not all columns in the tables are numeric. For output$calc
, it will try and sum those characters which for me causes a problem. So I added an if
statement which will look to see if the column is numeric or not (which uses dplyr
)

QUESTION
I am trying learn gnuplot and I want to to plot some comma separated data.
- x axis datetime stamp - enclosed in double quotes - containing a comma separator,
- y axis integer value data.
ANSWER
Answered 2022-Feb-24 at 09:38Check help time_specifiers
. Your year it 2 digits %y
not 4 digits %Y
.
The double quotes will make your date/time the first column. No need for extra double quotes in the format.
With the syntax set xdata time
and set timefmt "..."
you have only one format in the plot command.
If you are using the syntax timecolumn()
(check help timecolumn
) you can use different input time formats in your plot command.
Note: the format %p
as input format has been introduced in gnuplot 5.4.0
For older versions you have to use a workaround, see e.g. gnuplot: how to convert 12h time format into 24h time format?

Install xdata
You can use xdata like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
