How to use Modbus Register values in Dashboard

I want to use some values of Modbus Holding Register to appear in Dashboard in form of Chart and Gauges, How can I do that Because I am Unable to find any clue.

what have you tried and what is not working ?

have you tried putting a ui_chart node ?

Actually I am not good at Javascript, I want to extract those register values and use them in Dashboard.

that is the purpose of Node-Red, you dont need to know javascript.

Can You Please tell me one more thing as, I want to increase font size in dashboard.
How can I do that?

you should use template node for the dashboard, CSS is not my forte, however minimal adjustment we can try using <font size> in the 'ui_text' or 'ui_button' widgets.
please share your flow
