QUESTION
I am trying to get a scatter plot of 2 different variables, one set of scatter points is height values for a projectile under the effect of air resistant, and one is a projectile with no air resistance. I can get this working with 1 set of scatterpoints, but not both of them. I'm using the mplcursors library to show annotation labels when hovering over a point. This is the relevant code:
...ANSWER
Answered 2020-Jan-19 at 04:16Instead of connecting the cursors to the ax, try connecting them only to the scatter plot they belong to. The first parameter of mplcursors.cursor
is meant for just that.
You'll notice that when you move to a point from the other set, that the annotation of the previous one is not removed. Therefore, I added some code to remove the other annotation when a new one is opened.
Note that you can directly access the index via sel.target.index
. Calling get_index(airRangeValues, ...)
with a point of the wrong set could be a cause of the error you encountered.
Here's some code to demonstrate the principles. The backgroundcolor of the annotations is set differently to better illustrate which cursor is being displayed. Also, the alpha is changed to ease reading the text.

Background: I'm just fiddling around with an idea for simple templating which only provides if/for/render, to see how feasible it is and if it makes sense to use in my personal project. As opposed to using NVelocity or Razor, or anything else.
I've written a regular expression:

QUESTION
In debug mode program run well, but in Release mode have error memcpy operation
...ANSWER
Answered 2018-Jul-28 at 08:30It is very hard to understand your question. Please write a more complete error message and explanation of what you are doing next time!
My guess however is, that you run into the following problem: assert
statements are slow and therefore usually only compiled into your code in debug mode. In the release mode they are usually simply ignored.
In your code however, you are using a malloc
inside an assert
. Therefore in the debug version you get the memory you want, and in the release version you get nothing and the program crashes. The line is:
