"select particles" function improvement

Hi Didier,
For beam distribution, right-clicking for "select particles" is a powerful function. I think some improvement could be added if possible.
1. Rescale the coordinate range to a required region, e.g. from 10 to 100, and "select particles", the selected region is a little larger than what we defined (about from 9.5 to 100+, zoom in to check the distribution edge). Maybe it could be fixed?
2. Invert selection?
3. Only rectangular area could be selected. Is it possible to add other shapes? Like circle, triangle or ellipse？
Kinds,
shliu

Dear shliu,
1: You're rigth, it's fixed
2: Invert selection option has been added
3: Clearly not possible

Didier,
Thank you!
About the ellipse selection, how about cutting it according to the edge defined in "Charts - Output - Options - Emittance ellipses"?

Hi,
Yes, very good idea and much easier to implement.
Added in the last release.

Thank you!
Maybe the command "Select particles outside ellipse" is also necessary?
For example, how to select particles inside ellipse both in xx' and yy' planes?

Dear Shliu,
I don't think so, because thank to you, now you can inverse selection

Then select particles in yyp' plane:

The selected particles are in xx' ellipse OR yy' ellipse. How to select particles in xx' ellipse AND yy' ellipse at the same time?

Dear Shliu,
First select particles in the XX' chart, then in the TYY' chart to have both in the same time!

That is the way I did in the last post. Could you please check it?
If I choose it in xx' and yy', some particles outside of the ellipse in xx' but inside the ellipse in yy' would be chosen, which is not my purpose.

Dear Shlui,
Sorry, I didn't see the "AND".
Ok, it's done in the last release
