Alternatively, when plotting ggplot how can I have multiple inputs for x and y values plotted?

Do you mean add the columns together? Ex: 0.69 + 0.18? or do you want to separate them by commas? 0.69, 0.18?

It looks like you’re using a spreadsheet(Excel, Sheets?), you can just use the =SUM(number1, number2) function (as it is in Excel)

Or, try this.
