Sometimes your charts might get pretty busy. Even hard to read. You might want to break a lot of items up onto multiple charts. But if you want to keep everything on one chart, we've got you covered:
Step 1: Find the chart for which you want to zoom in.
Step 2: Simply click and drag the mouse over the area you'd like to see in more detail.
Step 3: When you release the mouse button, the chart will zoom into that specific area. Simply click on "Reset Zoom" when you're done to go back to the original chart.
