From what I see in the documentation, after having explored other table & charts plugins, I feel like Table Manager is one of the best table managers in the world possessing one of the worst charts features in the world.
The customization available for charts is contained into a single phrase.
Please have a look at the attached file with common chart customization available for chart.js
I would like to know your opinion about development in this direction.
I think you have a tremendous potential in hands. Today Table manager with a decent chart customization would be the reference in the world.
Otherwise, I saw that you don’t offer test version or website live demo neither a roadmap, while your refund policy doesn’t accept dissatisfaction as reason. As potential customer I don’t feel trust but gamble.
With all the best regards
