Please read: [https://docs.easyeda.com/en/Simulation/Headings/index.html](https://docs.easyeda.com/en/Simulation/Headings/index.html) The section in there on configuring voltage and current sources will explain where you've gone wrong. :)

You also need to read this section: [https://docs.easyeda.com/en/Simulation/Chapter4-Introduction-to-using-a-simulator/index.html](https://docs.easyeda.com/en/Simulation/Chapter4-Introduction-to-using-a-simulator/index.html) because you have not realised that the way you have configured the 5V source, it is at 5V for all time including t

Sorry, finger trouble: You also need to read this section in the Simulation Tutorial: [https://docs.easyeda.com/en/Simulation/Chapter4-Introduction-to-using-a-simulator/index.html](https://docs.easyeda.com/en/Simulation/Chapter4-Introduction-to-using-a-simulator/index.html) because you have not realised that the way you have configured the 5V source, it is at 5V for all time including t

Doh! It's the parsing for the forum. I forget that you can't use the greater than or less than symbol without escaping it and I can't be bothered to look up yet again how to do that. Try again. You also need to read this section: [https://docs.easyeda.com/en/Simulation/Chapter4-Introduction-to-using-a-simulator/index.html](https://docs.easyeda.com/en/Simulation/Chapter4-Introduction-to-using-a-simulator/index.html) because you have not realised that the way you have configured the 5V source, it is at 5V for all time including t less than 0 so the capacitor is already charged up to 5V before you start the transient simulation.
