(jqplot) How to show a small grid in the log scale graph?

Question

I have jqplot with the axis of the log scale, which looks like this:

And here is my x and y axis setup for my jqplot:

            axes : {
            xaxis : {
                renderer : $j.jqplot.LogAxisRenderer,
                ticks : [0.1, 1, 10, 100],
            },
            yaxis : {
                renderer : $j.jqplot.LogAxisRenderer,           
                ticks : [0.1, 1, 10, 100],
            },
        }

But I would like to show small grids that look exactly like this:

How can i do this?

Answer 1

max = 100;
min = 1;

// calculate the power of 10 of max value
var dcmMax = Math.floor(Math.log(max)/Math.log(10));

// calculate the power of 10 of min value
var dcmMin = Math.floor(Math.log(min)/Math.log(10));

var ticks = [];
var tick, f;

for (var i = dcmMin ; i <= dcmMax ; i++){

    tick = Math.floor(Math.log(i)/Math.log(10));

    if (i == dcmMin){
       ticks.push(tick.toFixed(1));
    }

    f = tick;

    for (var j = 0; j < 8; j++){
        tick = tick + f;
        ticks.push(myTick(tick.toFixed(1)));
    }

    if (i == dcmMax){
        ticks.push(tick.toFixed(1));
    }
}

function myTick(value){
return {value:value, showLabel:false, showMark:false};
}

this will create the main ticks from 1.0, 10.0, 100.0, 1000.0 and show only the grid without minor ticks, since the corresponding showLabel and showMark are set to false

Any answer better than mine?

    majorTicks = [      
                    1,
                    {value:2, showLabel:false, showMark:false},
                    {value:3, showLabel:false, showMark:false},
                    {value:4, showLabel:false, showMark:false},
                    {value:5, showLabel:false, showMark:false},
                    {value:6, showLabel:false, showMark:false},
                    {value:7, showLabel:false, showMark:false},
                    {value:8, showLabel:false, showMark:false},
                    {value:9, showLabel:false, showMark:false},
                    10,
                    {value:20, showLabel:false, showMark:false},
                    {value:30, showLabel:false, showMark:false},    
                    {value:40, showLabel:false, showMark:false},    
                    {value:50, showLabel:false, showMark:false},    
                    {value:60, showLabel:false, showMark:false},    
                    {value:70, showLabel:false, showMark:false},    
                    {value:80, showLabel:false, showMark:false},
                    {value:90, showLabel:false, showMark:false},    
                    100
                ];
