Recently we found out that there is a chance where the arrow icon in facet chart will disappear after slide the chart view left and right.
It happen when user slide the chart view so that the second column from the left shown as the first column. There will be an arrow icon at the left stating that there are still some columns at the left. When user click the arrow icon at the right side and the chart, the chart view will move to right side and when user click the left icon again, and the chart view will switch to previous view where the second column shown as the left most column again (Note: sometimes the first column will be the left most column instead of the second column). The arrow icon at the left may has chances to disappear.
Below is the link of a video which showing that the arrow icon is still exists at the first try but disappear at the second try:
