Increase size of selectable area of X dimension in Line Chart

Currently, the area in which one can make selections on a Line Chart X dimension appears to be limited by distance from the bottom of the chart. While this is not a major problem if the labels are Angled or Vertical, it makes it virtually impossible to make selections when the labels are Horizontal. I suggest increasing the size of the selectable area so users can actually make selections with Horizontal X-axis labels.
