When using Bar graphs, it can often be the case that there are multiple bars on the same timepoint. This may not always be the desired result. You can use the
barChart.handleOverlap option to automatically plot the bars next to eachother or stacked on top of eachother if they occupy the same timeslot. By default, this option is on, the bars overlap.
Use the dropdown box to experiment with the options. The stacked only really makes sense when using groups as is shown in the next example.
