Hi Anjali,

Thanks for sharing the screenshot! I will recommend you to make sure that you are viewing the correct "Attribute". From the picture, I can tell that you have selected the Attribute "ID", which tells us the domain number of a geometry. You are probably interested in "n" and "p". You can also remove the attributes such as ID and area, which you won't need most likely:


Now you can choose the "V_cathode" parameter and use the slider/up-down buttons to look at the charge density for different voltages. Another thing to note would be that, in the article, I believe they are using the log scale to look at the results, as shown below:
