Parameters

Description

drawaxis is used to draw an axis in vertical or horizontal direction. the direction of the axis is given by dir dir = 'u' or 'd' gives a horizontal axis with tics going up ( 'u' ) or down ( 'd' ). dir = 'r' or 'l' give a vertical axis with tics going right ( 'r' ) or left ( 'l' ).

x and y give the axis tics positions. If the axis is horizontal then y must be a scalar or can be omitted and x is a Scilab vector. The meaning of x is controlled by tics .

If tics='v' then x gives the tics positions along the x-axis.

If tics='r' then x must be of size 3. x=[xmin,xmax,n] and n gives the number of intervals.

If tics='i' then x must be of size 4, x=[k1,k2,a,n] . then xmin=k1*10^a , xmax=k2*10^a and n gives the number of intervals

If y is omitted then the axis will be positioned at the top of the frame if dir='u' or at the bottom if dir='d'

By default, numbers are drawn along the axis. They are drawn using a default format which can be changed with format_n . It is also possible to display given strings and not numbers, this is done if val is provided. The size of val must match the number of tics.

Examples


plot2d(1:10,1:10,1,"020")
// horizontal axis 
drawaxis(x=2:7,y=4,dir='u',tics='v')
// horizontal axis on top of the frame
drawaxis(x=2:7,dir='u',tics='v') 
// horizontal axis at the bottom of the frame
drawaxis(x=2:7,dir='d',tics='v') 

// horizontal axis given by a range 
drawaxis(x=[2,7,3],y=4,dir='d',tics='r') 

// vertical axis 
drawaxis(x=4,y=2:7,dir='r',tics='v')
drawaxis(x=2,y=[2,7,3],dir='l',tics='r')
drawaxis(y=2:7,dir='r',tics='v')
drawaxis(y=2:7,dir='l',tics='v')

// horizontal axis with strings displayed at tics positions
drawaxis(x=2:7,y=8,dir='u',tics='v',val='A'+string(1:6));
// vertical axis with strings displayed at tics positions
drawaxis(x=8,y=2:7,dir='r',tics='v',val='B'+string(1:6));

// horizontal axis given with a 'i' range. 
drawaxis(x=[2,5,0,3],y=9,dir='u',tics='i');
drawaxis(x=9,y=[2,5,0,3],dir='r',tics='i',sub_int=5);

// horizontal axis again 
drawaxis(x=2:7,y=4,dir='u',tics='v',fontsize=10,textcolor=9,ticscolor=7,seg=0,sub_int=20)
