Thanks all for the replies. I have no problem charting manually entered data [as you had suggest Jon], my issue is in grabbing data from a file on my web server and charting it.
I tried your code suggestions Sergey, but am still coming up with a blank screen. My code is shown below, hopefully someone can spot what I am doing wrong, rather than trying to give a verbal explanation of what to do. Sergey note I was unsure what the values should be in the csvColumns parameter. Since a search didn't reveal the definitions of the cvsColumns parameter, I assumed that 'number' meant there were number values in each column (which is true). Does there need to be a 'number' value stated for each column in the data array (a csv file with three [column] entries per line.) In which case my my parameter should be csvColumns: ['number', 'number', 'number'] Also at the end of the csvColumns line, in your code sample, the code used a "," (coma), Should that have really been a semi-colon (;) ? <html> <head> <script src="https://www.google.com/jsapi";> </script> <script src="http://code.jquery.com/jquery-1.10.1.min.js";> </script> <script src="jquery.csv-0.71.js"> </script> <script> google.load("visualization", "1", {packages:["corechart"]}); google.setOnLoadCallback(drawChart); ///////////// var csvURL = "http://192.168.1.90/tempsD1.txt"; var queryOptions = { csvColumns: ['number', 'number' /* Or whatever the columns in the CSV file are */], csvHasHeader: false /* This should be false if your CSV file doesn't have a header */ } var query = new google.visualization.Query(csvUrl, queryOptions); query.send(handleQueryResponse); function handleQueryResponse(response) { if (response.isError()) { alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage()); return; } var data = response.getDataTable(); / function drawChart() { // set chart options var options = { title: "Temperatures", legend: 'none' }; // create the chart object and draw it var chart = new google.visualization.LineChart(document.getElementById('chart_div')); chart.draw(data, options); } </script> </head> <body> <div id="chart_div" style="width: 900px; height: 500px;"></div> </body> </html> -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
