Hello, I am currently working on a function where I need my combo chart to be redrawn with new data when a button is clicked. I am not quite sure how to tackle this. I have the code to generate my json table in a file called generate_gp_graph.php. By default, I draw the graph with certain settings by using the example on the Google API page
google.charts.load('current', {'packages':['corechart']}); // Set a callback to run when the Google Visualization API is loaded. google.charts.setOnLoadCallback(drawChart); function drawChart() { var jsonData = $.ajax({ url: "generate_gp_graph.php", dataType: "json", async: false }).responseText; // Create our data table out of JSON data loaded from server. var data = new google.visualization.DataTable(jsonData); var options = { vAxis: {title: 'Value (€)'}, hAxis: {title: 'Audit Date'}, legend:{position: 'top', maxLines:2}, seriesType: 'bars', series: { 3: {type: 'line', targetAxisIndex:0}, 4: {type: 'line', targetAxisIndex:1} }, vAxes: { 1: { title:'Gross Profit %', textStyle: {color: 'green'} } }}; // Instantiate and draw our chart, passing in some options. var chart = new google.visualization.ComboChart(document.getElementById('chart_div')); chart.draw(data, options); } This is what I have tried to do when a button is clicked, and while it fetches the correct data and returns it, the chart is not redrawn. $('#year_to_date').click(function(event){ var page = 'generate_gp_graph.php'; $.ajax({ url : page, data : {'action' : 'year_to_date','store_id' : "<?php echo $store_id ?>"}, type : 'post', success: function(result) { function drawChart() { var jsonData = $.ajax({ url: "generate_gp_graph.php", dataType: "json", async: false }).responseText; // Create our data table out of JSON data loaded from server. var data = new google.visualization.DataTable(jsonData); var options = { vAxis: {title: 'Value (€)'}, hAxis: {title: 'Audit Date'}, legend:{position: 'top', maxLines:2}, seriesType: 'bars', series: { 3: {type: 'line', targetAxisIndex:0}, 4: {type: 'line', targetAxisIndex:1} }, vAxes: { 1: { title:'Gross Profit %', textStyle: {color: 'green'} } }}; // Instantiate and draw our chart, passing in some options. var chart = new google.visualization.ComboChart(document.getElementById('chart_div')); chart.draw(data, options); }}, error: function() {} }); }); How do I go about drawing the chart again when the data is received? -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
