Part of series: DD011 – Data-Driven Chart 011 Line Charts
These are six standard line charts. Line charts show trend. The values are not shown because the trend is the most important message. The best practice for line charts is to use the y axis as the value indicator, which is the exception to most chart types.
Some line charts get to look like spaghetti when there are a lot of lines. It's important to label these charts correctly so that your audience will have as little trouble as possible identifying the lines. We advocate for the labels to be on the right-hand side of the line - the end point - just outside the chart. That way an end ranking can also be established. As more charts are placed on the slide, however, space becomes a consideration. You may want to add a legend at this point or put the labels within the chart with a leader line.
