    <p>Hi Guys I was wondering if I can pass my hidden input value to supply data in Google Chart, I have a few radio buttons designed to change the data to be stored in the hidden input, I've checked on this and my code for changing the data seems to work but the chart doesn't get redrawn. How can I trigger something like a redraw function.Thanks.</p> <pre><code>google.setOnLoadCallback(drawChart); function drawChart() { var sample_data = document.getElementById('sample_data').value; var data2 = eval("["+sample_data+"]"); var data = new google.visualization.arrayToDataTable(data2); var options = { hAxis: {title: 'Age', minValue: 0,maxValue:105}, vAxis: {title:'Savings', minValue: 0,maxValue:2500000}, width: 960, height: 300, colors: ['#4a82bd'], legend:'none' }; var chart = new google.visualization.AreaChart(document.getElementById('chart_div')); chart.draw(data, options); } drawChart(); function ViewModel() { var self =this; self.rangeSelect = ko.observable('0%'); self.dataGetter = ko.computed(function(){ var range = self.rangeSelect(); if(range=='0%'){ return "['Age','Savings'],"+ "[25,0],"+ "[26,2738],"+ "[27,5834],"+ "[28,9278],"+ "[29,13191],"+ "[30,17592],"+ "[31,22288],"+ "[32,27418],"+ "[33,32993],"+ "[34,38954],"+ "[35,45304],"+ "[36,52127],"+ "[37,59254],"+ "[38,66663],"+ "[39,74535],"+ "[40,83148],"+ "[41,91537],"+ "[42,100823],"+ "[43,110002],"+ "[44,119837],"+ "[45,129897],"+ "[46,141052],"+ "[47,152166],"+ "[48,163757],"+ "[49,175561],"+ "[50,188520],"+ "[51,200952],"+ "[52,214325],"+ "[53,228245],"+ "[54,243532],"+ "[55,259149],"+ "[56,274371],"+ "[57,290571],"+ "[58,307564],"+ "[59,322976],"+ "[60,340957],"+ "[61,358337],"+ "[62,375345],"+ "[63,392495],"+ "[64,410609],"+ "[65,428638],"+ "[66,400252],"+ "[67,370044],"+ "[68,340162],"+ "[69,306514],"+ "[70,274417],"+ "[71,239492],"+ "[72,205637],"+ "[73,169858],"+ "[74,133103],"+ "[75,97019],"+ "[76,58116],"+ "[77,19529],"+ "[78,0],"+ "[79,0],"+ "[80,0],"+ "[81,0],"+ "[82,0],"+ "[83,0],"+ "[84,0],"+ "[85,0],"+ "[86,0],"+ "[87,0],"+ "[88,0],"+ "[89,0]";

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
