yarr | yet another rss reader

I have several arrays (more than this, about 20 x arrays and 20 y arrays) but this is an example

I'm using this snippet for my custom group (from here) to allow prefixes.

I'm currently looking to get this bit of code working in MatLab. I just wondering what form xarr and yarr have to be in for this to return values corresponding to coordinates of points within a circle.

cir1=find((xarr-cirx1).^2 + (yarr-ciry1).^2 <=cirr1^2);

Any help is greatly appreciated.

Say I have four arrays and also an x and y array

I am trying to plot two arrays that are input via command line. For instance I have the program testarray.py

Now when I enter the command line

I am trying to plot a surface created with >10000 unstructured triangles. I have the coordinates of the triangle points and the each triangle points list. My data is as follows,

0.1 0.2 0.1
0.2 0.4 0.6
0.4 0.6 0.4
.
.
.
1 2 3
.
.
.

The first three lines are coordinates (-X,Y,Z COORDINATES-) of the points (point 1 in line 1, point 2 in line 2 and etc). The number of points are more than 10000. The "1 2 3" says that we have a triangle in which its corner points are 1, 2 and 3. So, I want to plot the surface by starting from the 1st triangle and plotting them one by one. I have tried to follow the above procedure but I do not get the right figure and finally I get the following error message.

Figure size 432x288 with 0 Axes

I have tried the following code.

I need to display below the cursor, coordinates (x,y,z) on a 2D plots. Consider this minimal working example (I compactified as much as I could from my longer code).

If you run it, you will see that the Z coordinate is the good one for the second graph but not for the same. But the Z values that should be taken by the function format_coord that I provide to ax.format_coord are updated between my two plots.

Then, I am not sure to understand this behavior.

How can I fix it ?

As a sidenote: I took the function from format_coord from a stackexchange post... That I do not find anymore... If I find it I will attach the link (I am not super confortable with tricks with pyplot, consider me as a beginner).

I am trying to make a chart with background as a colormap in python. I am using the following code:

To reproduce:

1. Run the Code Snippet (recommend Full Page mode)
2. Hold Ctrl or Shift while clicking to select multiple 'species' in the table column header
3. Note that while the key is held down, the table data is filtered according to selected 'species'
4. Release the key, observe changes in filtered table data

I think this is probably related to https://github.com/olifolkerd/tabulator/issues/975 and that I need to do something to override default tabulator keypress events.
