If ‘Up to 20% of pile dia’ is selected, this option will plot the tz curves with z values ranging from 0 to 20% of equivalent pile diameter. This helps with better visualization of the tz curves since most of the values lie within this range before the tz chart levels off.
b) Selected depths / All depths. Use the toggle switch to select one of the options. If ‘Selected depths’ is selected, this option will plot only the tz curve associated with the depth selected in the ‘tz Depth Table’. This option is useful to inspect a particular tz chart.
