Is there a standard way of how to add markers to the x- and y-axes?

[q2apro]

With:

    ports: [{
        id: "CSCanvas",
	axes: true,
	grid: true,

the x-y-axes show up, and the nice grid.

Is there a standard way of how to set markers at the axes?

For instance, every 1 unit a "1", "2", ... and a little visual marker -.

Example:

as far as I know,the answer is no. You have to script that.

This is one possible solution (scripting it oneself):

// coordinate markers and labels for x-axis and y-axis
list = -4..4;
repeat(
	length(list),
	draw((-0.1,list_#),(0.1,list_#), color->(0.75, 0.75, 0.75));
	draw( (list_#,-0.1),(list_#,0.1), color->(0.75, 0.75, 0.75) );
	if(
		list_#!=0, 
		drawtext( (-0.49, list_#-0.08), list_#, size->10, color->(0.5,0.5,0.5) );
		drawtext( (list_#, -0.5), list_#, size->10, color->(0.5,0.5,0.5), align->"center" );
	);
);

The code could be simplified slightly:

list = -4..4;
forall(list,
	draw((-0.1,#),(0.1,#), color->(0.75, 0.75, 0.75));
	draw( (#,-0.1),(#,0.1), color->(0.75, 0.75, 0.75) );
	if(
		#!=0, 
		drawtext( (-0.49, #-0.08), #, size->10, color->(0.5,0.5,0.5) );
		drawtext( (#, -0.5), #, size->10, color->(0.5,0.5,0.5), align->"center" );
	);
);
