<div dir="ltr">Dear XCrySDen users,<div><br></div><div style>Excuse me if my question has been asked before, I could not find any direct answer to it. </div><div style><br></div><div style>I would like to plot the difference in charge density for three systems: pristine graphene, p-doped graphene, and n-doped graphene. For that purpose I thought I could subtract the different charge densities and plot the difference in order to see where the excess charge is located (if it is delocalized or not, for instance) . But I have some trouble understanding the Datagrid format, and in particular what is described on the XCrySDen website as <span style="background-color:rgb(255,255,255)">"<span style="color:rgb(0,0,0);font-family:arial,helvetica,verdana,sans-serif;text-align:justify">5x5x5 datagrid values in column-major mode". </span></span></div>
<div style><span style="background-color:rgb(255,255,255)"><span style="color:rgb(0,0,0);font-family:arial,helvetica,verdana,sans-serif;text-align:justify"><br></span></span></div><div style><span style="background-color:rgb(255,255,255)"><span style="color:rgb(0,0,0);font-family:arial,helvetica,verdana,sans-serif;text-align:justify">What does this part of the charge density data grid represent?</span></span></div>
