Gets a ratio of how wide to draw the HLOC lines relative to the horizontal axis's category widths, as a percentage in the range of 0 to 1.
A value of 1 uses the entire space, while a value of 0.6 uses 60% of the category's available space. The actual element width used is the smaller of the columnWidthRatio property and the maxColumnWidth property. Multiple element series divide this space proportionally. The default value is 0.65.
