Sorry but the meters in EasyEDA do not display readings directly in the schematic. The Voltmeter is a handy graphical device to indicate to someone looking at a schematic where a voltage difference is being measured in a circuit. Internally to the simulator, it also tells ngspice which nodes to measure the voltage difference between and to either display them as voltages in a DC op pnt SImulation Results window or in a WaveForm plot when a Transient (time domain) or AC (frequency domain) simulation is run. Similarly, the Ammeter is a handy graphical device to indicate to someone looking at a schematic where a current is being measured in a circuit. Internally to the simulator, it also tells ngspice which to measure the current between two nodes and to either display them as currents in a DC op pnt SImulation Results window or in a WaveForm plot when a Transient (time domain) or AC (frequency domain) simulation is run.
