Just purchased component. Though initially it seems to be pretty straightforward, I was disappointed that it included NO instructions. I would like to know how to: "show all the charts on the same page (in the tabs view)"
I can't find the directions anywhere in the forum nor in the admin end of things itself. It's quite unclear.

Also, is there a way to add additional templates into the system?

In site's BE the instructions are provided in the Help of the component.

To output some Charts'tabs on one page you should check necessary charts in the column "Include to tabs". Put the checked charts in the same category. Create a new menu item in the Menu Manager, selecting Comparison chart.
In Parameters (Components) select a category from the category list and select "Yes" in the "Show in tabs" combo box. Click "Save" to add a menu item for this component.
In Setup charts you can choose an option "Turn on/off hidden rows" as well.

There're 2 templates and "Template manager", using it you can set its view.
By the way, there's the public code, so you can customize it as you'd like. Also we could offer our custom development, if you need smth to develop.

Regards

I too am interested in this feature .It sems to be a potentially useful. But having tested it, it doesn't produce styled tabs, but merely a set of links to the other charts within the category. To be commercially useful, it would need some styling, with real, cusomizable tabs that are intuitive and instructive to the user. Can we expect that in future releases?

Editing tabs' CSS in the plugin for tabs, it's possible to change the tabs' layout. Thereby you could set the 'tabs face' to a particular site.
