both text and numbers in axis

I'm wondering if matlab is able to customize the axis where some of the ticks are strings and some of the ticks are number?

or inconsistent tick marks (for example, tick marks 1-5 in 1 tick intervals, then 5-100 in intervals of 5?

Answer 1

set(gca, 'XTick', [1 2 3 4 5 10 15])
set(gca,'XTickLabel',{1 2 3 4 'Hello' 10 15})

works like a charm Walter

now I ran into the issue of the primary and secondary axis not aligned

my primary goes from -5 to 20 in increments of 5 and my 2ndary goes from -5 to 100 in increments of 10
both axes from -5 to 0 goes from increments of 1.

the 0 on the 2ndary axis is much lower than the 0 on the primary axis :(

I'm not sure what you are referring to about primary and secondary axis? Are you using plotyy() ?

yessir! but i figured it out

I had to manually scale the axes to make the ticks match the values

I'm grateful as always :)
