## Can you start a graph not at 0?

Data in a line chart is encoded by position (x, y coordinates), whereas in a bar chart data is represented by length. This subtle difference changes the way a reader uses the chart, meaning that in a line chart it’s ok to start the axis at a value other than zero, despite many claims that they are always misleading.
