Newly Installed Plugins are not showing (Window Platform)

I have installed some plugins to use it for plotting data . These plugins are showing in plugin folder but not in dashboard while selecting visualization . Please see attached images.

.
After successful installation i have restarted grafana service and refreshed browser. Newly installed plugs are not even showing on http://localhost:8080/plugins ?
Just these plugins are showing in plugin list. That’s a main issue how i can enable newly installed plugins.
Can you please provide me the steps to enable these newly installed plugin? If i have done any mistake while installing can you highlight any problem and how i can solve this issue?
