Line graph with ggplot2 in R Studio : <p>I am trying to learn the R programming language to analyse and visualize my data. I have made some good progress so far and I am really enjoying learning R but I am stomped here.</p>

<p>I am having some trouble creating line graphs for products in specific categories. I have no problem creating graphs to show sales all categories but I would like to specify a particular category and show the <strong>product</strong> sales.</p>

<p><a href="https://i.stack.imgur.com/dh6OK.png" rel="nofollow noreferrer">This is what my data set looks like.</a>  </p>

<p>Can someone show me how I could do this? E.g I would like to create a <strong>line</strong> graph to show the sales of Products in the <strong>Bakery</strong> category where the <strong>X</strong> axis would have the product name and the <strong>Y</strong> axis would have the quantity sold.</p>

<p>Any help would be greatly appreciated.</p>
