MATLAB: Can anyone help me with the water level tank (sltank) example available on Matlab

s-functionsimulink

what does the following mean?

1-axis equal

2-Box on

3-XTick, YTick

doc axis
doc box
doc axes_props

There is user data "hidden" in the figure 'tankdemo'. The user data gets extracted into the variable 'yData' by the line

yData=get(tankHndlList(1),'YData');

yData(1) is the offset. yData(3:4) the height. The next lines use yData([3 4]), which means the same.

Elysi, not quite sure, what you need to do, but this does the trick:

 set(gca,'XTickLabel',{'PCA', 'LDA'},'XTick',[1 2]);
