有谁知道如何在 Jqplot 中使“y 轴”值从 0 开始......默认情况下它以负值开始，例如：-500、0、500、1000 等等......请帮助

Set min: object (minimum) to 0 within axes: object

$(document).ready(function(){
 // your code here... //
 axes:{
  yaxis: {min:0}
 }
})

As rsapru suggested, a max: object (maximum) value is recommended to bound the graph to your preferred range. For example, if you wanted the minimum to be 0 and maximum to be 7500

 axes:{
  yaxis: {min:0, max: 7500}
 }

If you want to specify the graduations of the ticks you can do so manually by specifying ticks with the ticks: object or have jqPlot calculate tick spacing automatically (nothing other than min and max objects would be needed in that case) or by your specific number of ticks (using numberTicks: object)

Example: For tick 100 units apart, from 0 to 1000, using 11 ticks (0,100,200,300,400,500,600,700,800,900,1000) jqPlot automatic calculation:

 axes:{
  yaxis: {min:0, max: 1000, numberTicks: 11}
 }

Example: For tick 100 units apart, from 0 to 1000, using 11 ticks (0,100,200,300,400,500,600,700,800,900,1000) manual specification:

 axes:{
  yaxis: {min:0, max: 1000, Ticks: [[0],[100],[200],[300],[400],[500],[600],[700],[800],[900],[1000]]}
 }

                var plot2 = $.jqplot ('chartdiv', getRequestStats(), {
                // Give the plot a title.
                title: 'Daily Request Status',
                // You can specify options for all axes on the plot at once with
                // the axesDefaults object.  Here, we're using a canvas renderer
                // to draw the axis label which allows rotated text.
                axesDefaults: {
                    labelRenderer: $.jqplot.CanvasAxisLabelRenderer
                },
                // An axes object holds options for all axes.
                // Allowable axes are xaxis, x2axis, yaxis, y2axis, y3axis, ...
                // Up to 9 y axes are supported.
                axes: {
                    // options for each axis are specified in seperate option objects.
                    xaxis: {
                        label: "Hour",
                        // Turn off "padding".  This will allow data point to lie on the
                        // edges of the grid.  Default padding is 1.2 and will keep all
                        // points inside the bounds of the grid.
                        pad: 0
                    },
                    yaxis: {
                        label: "Count",
                        pad: 0
                    }
                }
            });

pad: 0 将使 Y 轴从 0 开始。

Refer to http://www.jqplot.com/docs/files/jqPlotOptions-txt.html

set yaxis: {min: 0, max: 500, numberTicks:5}

在您的 yaxis 中添加 yaxis: {min:0}

以下解决方案对我有用。

-> 在数组中添加零值。

-> 将数据渲染设置为 $.jqplot.CanvasAxisLabelRenderer

yaxis：{渲染器：$.jqplot.CanvasAxisLabelRenderer .....

                    }

谢谢阿德南

将以下内容添加到脚本中：

yaxis: {
    minimum:0
}

在你的 yaxis 中。我试过了，它有效。
