jq plot - 获得线性x轴刻度

Question

我有一个jqPlot图表,如下图所示.

我使用LinearAxisRenderer作为x轴.

但x轴值为0,1,1,2,2等.

有没有办法让值为0,1,2,3等.

提前致谢.

代码:

 $.jqplot(ctrlId, [graphPt], {
        title: chartTitle,
        seriesDefaults: {
            renderer: $.jqplot.BarRenderer,
            pointLabels: { show: true, location: 'e', edgeTolerance: -15, formatString: '%s' },
            shadow: false,
            rendererOptions: {
                barDirection: 'horizontal',
                barMargin: 2
            }
        },
        axesDefaults: {
            renderer: $.jqplot.canvasAxisTickRenderer,
            min: 0,      // minimum numerical value of the axis.  Determined automatically.
            pad: 1.3,       // a factor multiplied by the data range on the axis to give the
            // axis range so that data points don't fall on the edges of the axis.

            tickOptions: {
                mark: 'outside',    // Where to put the tick mark on the axis 'outside', 'inside' or 'cross',
                markSize: 95,                  // 
                showGridline: false, // wether to draw a gridline (across the whole grid) at this tick,
                show: true,         // wether to show the tick (mark and label),
                showLabel: true,    // wether to show the text label at the tick,
                formatString: '%d'   // format string to use with the axis tick formatter
            },
            showTicks: true,        // wether or not to show the tick labels,
            showTickMarks: true    // wether or not to show the tick marks
        },

        axes: {
            yaxis: {
                renderer: $.jqplot.CategoryAxisRenderer
            },
            xaxis: {
                 renderer: $.jqplot.LinearAxisRenderer,
                tickOptions: {
                    mark: 'cross', 
                    markSize: 2
                }
            }
        }
    });

添加tickinterval属性到您的xaxis设置.

xaxis: {
             renderer: $.jqplot.LinearAxisRenderer,
            tickOptions: {
                mark: 'cross', 
                markSize: 2,   
            },
            tickInterval: 1 //ADD THIS
        }

从jqplot文档:

tickInterval - 刻度之间的单位数.与numberTicks互斥.
