Hi all,

Kindly i have a page and in the page i have two pie charts, (i'm using Jqplot pie chart)
i want to display different background color for the 2 charts but it is embeded in the css file!
is there any option to use any color?? or to make it transparent?
my code:

PieTimer[index] = jQuery.jqplot(PieTimerId,
TimerValuesArray,
{
seriesDefaults: {
shadow: false,
seriesColors: ["#13e837", "#6e869b"],
renderer: jQuery.jqplot.PieRenderer,
rendererOptions: {
highlightMouseOver: false,
diameter: 40,
padding: 0,
showDataLabels: false,
startAngle: 270,
sliceMargin: 0,
shadowOffset: 0,
shadowAlpha: 0,
shadowDepth: 0,
drawBorder: false,
shadow: false,
borderWidth: 0
}
},
legend: { show: false, location: 'w'}//
}

);

i'm wondering if i can set a property (ex: backgroundcolor ...) when drawing the chart?

another way:

CSS
According to the jqPlot options page (http://www.jqplot.com/docs/files/jqPlotOptions-txt.html) you have a option called grid where you can set all the grid parameters, one of this parameters is background color.
grid: {
    drawGridLines: true,        // wether to draw lines across the grid or not.
    gridLineColor: '#cccccc'    // *Color of the grid lines.
    background: '#fffdf6',      // CSS color spec for background color of grid.
    borderColor: '#999999',     // CSS color spec for border around grid.
    borderWidth: 2.0,           // pixel width of border around grid.
    shadow: true,               // draw a shadow for grid.
    shadowAngle: 45,            // angle of the shadow.  Clockwise from x axis.
    shadowOffset: 1.5,          // offset from the line of the shadow.
    shadowWidth: 3,             // width of the stroke for the shadow.
    shadowDepth: 3,             // Number of strokes to make when drawing shadow.
                                // Each stroke offset by shadowOffset from the last.
    shadowAlpha: 0.07           // Opacity of the shadow
    renderer: $.jqplot.CanvasGridRenderer,  // renderer to use to draw the grid.
    rendererOptions: {}         // options to pass to the renderer.  Note, the default
                                // CanvasGridRenderer takes no additional options.
},

 An example of usage is:
var plot1 = jQuery.jqplot ('chart1', [data],
{
    seriesDefaults: {
        // Make this a pie chart.
        renderer: jQuery.jqplot.PieRenderer
    },
grid: {
    drawGridLines: true,        // wether to draw lines across the grid or not.
        gridLineColor: '#cccccc',    // *Color of the grid lines.
        background: '#ffff66',      // CSS color spec for background color of grid.
        borderColor: '#999999',     // CSS color spec for border around grid.
        borderWidth: 2.0,           // pixel width of border around grid.
        shadow: true,               // draw a shadow for grid.
        shadowAngle: 45,            // angle of the shadow.  Clockwise from x axis.
        shadowOffset: 1.5,          // offset from the line of the shadow.
        shadowWidth: 3,             // width of the stroke for the shadow.
        shadowDepth: 3
},
  legend: { show:true, location: 'e' }
}
);
