    copied!<p>I'm currently using jqplot to display some charts and prepare javascript code with php.</p> <p>On one of my chart, I use Ajax to get a new chart. For this, I get a json array with the list of values and chart option as a string like this :</p> <p>This is the JSON I get : </p> <pre><code>{"idGraphe":"bar_chart_5","conditions":"[]","data":"[[[1,80423],[2,62634],[3,70625],[4,72187],[5,72739],[6,70078],[7,72751],[8,74300],[9,75550],[10,72482],[11,70971],[12,77579]],[[1,73386],[2,70068],[3,85018],[4,69761],[5,75317],[6,68240],[7,72487],[8,74716],[9,74340],[10,75012],[11,74800],[12,83105]]]","options":"{series : [{label : 'consommationtotale Pilote1' , yaxis : 'yaxis' },{label : 'consommationtotale Pilote2' , yaxis : 'yaxis' }] , seriesDefaults : {renderer : $.jqplot.BarRenderer , rendererOptions : {barWidth : null} } , cursor : {show : true , zoom : true, showTooltip : false}, highlighter : {showTooltip : true , tooltipAxes : 'both' , tooltipContentEditor : getPointInfo , show : true} , title : 'Bar chart', legend : {show : true , renderer: $.jqplot.EnhancedLegendRenderer}, axes : {xaxis:{ tickRenderer:$.jqplot.CanvasAxisTickRenderer , renderer: $.jqplot.CategoryAxisRenderer,pad : 0 , label : 'mois' , labelRenderer: $.jqplot.CanvasAxisLabelRenderer}, yaxis:{ label : 'consommationtotale' , labelRenderer: $.jqplot.CanvasAxisLabelRenderer }}}"} </code></pre> <p>And this is the part I have problem with : </p> <pre><code>"{series : [{label : 'consommationtotale Pilote1' , yaxis : 'yaxis' },{label : 'consommationtotale Pilote2' , yaxis : 'yaxis' }] , seriesDefaults : {renderer : $.jqplot.BarRenderer , rendererOptions : {barWidth : null} } , cursor : {show : true , zoom : true, showTooltip : false}, highlighter : {showTooltip : true , tooltipAxes : 'both' , tooltipContentEditor : getPointInfo , show : true} , title : 'Bar chart', legend : {show : true , renderer: $.jqplot.EnhancedLegendRenderer}, axes : {xaxis:{ tickRenderer:$.jqplot.CanvasAxisTickRenderer , renderer: $.jqplot.CategoryAxisRenderer,pad : 0 , label : 'mois' , labelRenderer: $.jqplot.CanvasAxisLabelRenderer}, yaxis:{ label : 'consommationtotale' , labelRenderer: $.jqplot.CanvasAxisLabelRenderer }}}" </code></pre> <p>My problem is that in order to draw the chart with proper options, I need to pass this as a javascript object. And that what I can't figure how to do to convert my string to the corresponding javascript object.</p> <p>I tried to cast it as an object but without success, I've not so much ex^periences with javascript.</p> <p>Does anyone would have a solution or a tip ?</p> <p>Thanks</p>
