can i do real time plotting with values fetched from .json file?

Can you describe in more detail what you are trying to do? If you provide an example of the values fetched we'll be better able to help you.

sorry for being less informative, i want to plot real time ecg data fetched from ecg sensors, so is there anyway update the values on the graph per certain time?

Hello, thank you for describing your problem. Maybe you could fetch the data from the ECG sensors periodically to a buffer and apply the ECG analysis functions we provide. If your buffer contains a few seconds of the signal, I don't see why it wouldn't work. In order to show a plot and update it in real time, you could try something similar to this: https://learn.sparkfun.com/tutorials/graph-sensor-data-with-python-and-matplotlib/update-a-graph-in-real-time

thanks for sharing the information , i tired to do the same , store the values in a text file and plot but to plot the graph it was asking for more than 100 readings , which caused the delay to plot the graph , the link which you have sent seems will work , i will give that a try , thank you very much for your help really appreciate it :)
