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.
if you know how to post your flow, please share,

Can You Please tell me one more thing as, I want to increase font size in dashboard.
