Thanks asgallant for the response but i am still not clear. My requirment is to basically get the max value in a particular date range. To be more precise is it possible to execute the build the below query in Java scripts with a CSV file.
Select max(license) where Date = '01/02/2013' Also find below the code that i have written so far. I am not sure if i can achieve my above requirment using getFilteredRows. Also I would prefer a solution to use the query language to retrieve rows rather than the getFilteredRows on datatable. <!DOCTYPE html> <html> <head> <title>Google Chart Example</title> <script src="https://www.google.com/jsapi";></script> <script src="http://code.jquery.com/jquery-1.10.1.min.js";></script> <script src="http://localhost/jquery.csv-0.71.js";></script> <script type="text/javascript"> google.load("visualization", "1", {packages:["gauge"]}); </script> <script> function drawChart() { //$.get("http://localhost/output.csv",function(csvString) //{ var queryOptions = { //csvColumns: ['string','string','string','date','string','number','number','number','string','string','string','number','string','string','string','string','string'], //csvColumns: ['string','string','string','string','string','string','string','string','string','string','string','string','string','string','string','string','string'] csvColumns: ['string','number','number'], csvHasHeader: true } //csvUrl= 'http://localhost/output.csv'; csvUrl= 'http://localhost/temperatures.csv'; var query = new google.visualization.Query(csvUrl,queryOptions); //var query = new google.visualization.Query('http://spreadsheets.google.com/tq?key=pCQbetd-CptGXxxQIG7VFIQ&range=B1:D11&pub=1'); //var arrayData = $.csv.toArrays(csvString, {onParseValue: $.csv.hooks.castToScalar}); query.setQuery('SELECT A,B WHERE C > 6'); query.send(handleQueryResponse); function handleQueryResponse(response) { //alert(response.status); if (response.isError()) { alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage()); return; } var data = response.getDataTable(); var dataView1 = new google.visualization.DataView(data); dataView1.setRows(data.getFilteredRows([{minValue: 6,column: 2}])); dataView1.setColumns([1]); var chart = new google.visualization.Gauge(document.getElementById('chart')); chart.draw(dataView1,{width: 400, height: 250,redFrom: 18, redTo: 20,yellowFrom:15, yellowTo: 17,minorTicks: 5,min: 1,max: 20,animation:{duration: 400,easing: 'linear'}}); } } google.setOnLoadCallback(drawChart); </script> </head> <body> <div id="chart"> </div> </body> </html> On Friday, 31 January 2014 15:09:00 UTC+1, Ashok Kumar wrote: > Hi, > > I am not able to filter and display the gauge chart based on my query. > Also the gauge chart is always displayed for the entire CSV data and not > based on my query.Find below the code that i used. > > <!DOCTYPE html> > <html> > <head> > <title>Google Chart Example</title> > <script src="https://www.google.com/jsapi";></script> > <script src="http://code.jquery.com/jquery-1.10.1.min.js";></script> > <script src="http://localhost/jquery.csv-0.71.js";></script> > <script type="text/javascript"> > google.load("visualization", "1", {packages:["gauge"]}); > </script> > <script> > function drawChart() > { > //$.get("http://localhost/output.csv",function(csvString) > //{ > var queryOptions = > { > //csvColumns: > ['string','string','string','date','string','number','number','number','string','string','string','number','string','string','string','string','string'], > //csvColumns: > ['string','string','string','string','string','string','string','string','string','string','string','string','string','string','string','string','string'] > csvColumns: ['string','number'], > csvHasHeader: true > } > //csvUrl= 'http://localhost/output.csv'; > csvUrl= 'http://localhost/temperatures.csv'; > var query = new google.visualization.Query(csvUrl,queryOptions); > //var query = new google.visualization.Query(' > http://spreadsheets.google.com/tq?key=pCQbetd-CptGXxxQIG7VFIQ&range=B1:D11&pub=1' > ); > //var arrayData = $.csv.toArrays(csvString, {onParseValue: > $.csv.hooks.castToScalar}); > query.setQuery('select B,C where C > 6'); > query.send(handleQueryResponse); > function handleQueryResponse(response) > { > if (response.isError()) > { > alert('Error in query: ' + response.getMessage() + ' ' + > response.getDetailedMessage()); > return; > } > var data = response.getDataTable(); > //alert(data[1,1]); > //var dataView1 = new google.visualization.DataView(data); > //dataView1.setColumns([1]); > var chart = new > google.visualization.Gauge(document.getElementById('chart')); > chart.draw(data,{width: 400, height: 250,redFrom: 18, redTo: > 20,yellowFrom:15, yellowTo: 17,minorTicks: 5,min: 1,max: > 20,animation:{duration: 400,easing: 'linear'}}); > } > } > google.setOnLoadCallback(drawChart); > </script> > </head> > <body> > <div id="chart"> > </div> > </body> > </html> > > This is my CSV Data. > > Label,License_Utilized,validation > License,10,5 > License1,18,7 > > Thanks, > Ashok > > > > > > -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
