The following resources allow you to contol the position of the title relative to its axis: tiMainJust tiMainPosition tiXAxisJust tiXAxisPosition = "Right" tiYAxisJust = "CenterLeft" tiYAxisSide = "Right" tiYAxisPosition = "Bottom"
The ~C~ will put a carriage return in a text string. By default it is left justified. If you need it centered, you will have to add spaces.
Use a ~Z#~ to resize text in mid-stream. The # refers to the percent of normal.
If your data has a long_name and units attribute, they will be placed in the gsnLeftString and gsnRightString respectively. You can turn these automatic labels off by setting the string resource to a null string " ".
You can not change all the font heights with one resource. Each title is controlled separately by:
The special gsn strings are added in the plot templates. They are not official titles, and therefore their font heights are not controlled by title (ti) resources, but rather by the gsn resource gsnStringFontHeightF. txFontHeightF can also be used to set the three gsn string font heights. Note that either of these two resources affects all of the strings equally. You can also set the font height of each of the three strings seperately, see Example 6 below.
As to why the gsn strings are not by default on the same vertical plane, NCL draws the gsn strings along a baseline that is set at the absolute bottom of the text strings. When the characters q, g, y, p, or j are part of the text string (as is the case here for the Left and Right Strings), the baseline is set at the bottom of those letters, slightly raising the text strings in the vertical.
