[SOLVED] JSXGraph: Is it possible to manually set the x and y tick distance

JSXGraph: Is it possible to manually set the x and y tick distance

Say one draws an axis inside a given bounding box, and the ticks are automatically placed. How about placing more/fewer/different ticks along the axes? Is it possible to change the distance of x and y ticks?

EDIT:

I managed to control minorTicks, but ticksDistance and ticksDelta do not have an effect, see MWE in JSFiddle.

Solution

You are already very close to the solution. The only missing attribute is insertTicks: false, which disables the automatic insertion of major ticks. ticksDelta is not necessary. Here is the code:

const brd0 = JXG.JSXGraph.initBoard('BOARDID0', { 
  boundingbox: [-1, 11, 12, -11], axis:true, 
  defaultAxes: {
    x: {
       withLabel: true, 
       name: 't in s',
           label: {
             position: 'rt', 
             offset: [-0, 15], 
             anchorX: 'right'
           },
           ticks: {
             insertTicks: false,
             ticksDistance: 5, 
             minorTicks: 4
           } 
        },
    y: {withLabel:true, name: 'x in m',      
        label: {position: 'rt', offset: [+15, -0]} } },
  showCopyright: false, showNavigation: false 
});

Additionally, I set minorTicks:4. See it live at https://jsfiddle.net/sxpm1z35/2/
