You click on a dot. Because it runs very slowly in the web, it might need multiple clicks on the dot :)
The diversity plot _should_ show how many variants a gene lasts over time. In the web one, because of perf you cant have alot of population and steps(mating to make new ones) it looks kinda flat :) If you increase the population and steps substantially, it will run _much_ slower and take alot longer for a generation, but you should end up with more diversity.
Id really only recommend doing this on the desktop version :)
I'll check to make sure thats all working properly. I havent looked at this for a while.
See above note. I suspect it cant write the inifile. If you want, you can edit it yourself. In the data folder there is biosim4.ini. This is what the app uses for its data - changing it here is the same as changing it in the ui.
Another alternative is to give the app write permissions (this might be why your settings dont save).
Sorry I didnt get back sooner. I'll check this. It _might_ be due to the app needing to access local folder. Make sure you extract it to somewhere like Documents where you have local access to folders.
The evolving algo may stabilize. Thats kind of normal, where dominant genes basically end up being all over the place. And thus evolutionary changes are smaller.
If you change mutation rates and similar, you should see a mort chaotic system.
