问题 I've specified HTML toolips in the options, but it still renders the HTML text in the tooltip instead of the result of the HTML. How can I fix this so that it renders the HTML result? I create a data view and set the columns like so: projectView.setColumns([0,1,3,{ type:'string', role:'tooltip', calc:function(dt,row){ var date = dt.getFormattedValue(row,0); var totalErrors = dt.getFormattedValue(row,3); var percent = Math.round((dt.getValue(row,3)/dt.getValue(row,1))*100); return '<div><b>'+

问题 I settled on using Google Charts to draw the data from an auto-updating Google Sheet that draws from my Analytics account (the analytic API wasn't working out). I've done quite a lot of reading, but I'm finding the query language reference to be a pain.

问题 I am using area charts from google charts and I wondered if there is a way to set the opacity for each line ? See this example : https://developers.google.com/chart/interactive/docs/gallery/areachart?hl=nl#SimpleExample If I use areaOpacity: 0.0 in the parameter array , it will hide all color underneath the lines, but I want the opacity of the red line (sales) to be 0.0 (which should hide it).

问题 I require my Google chart to be drawn with dynamic data, so I'm storing it in a variable: var rowData = "[ [{ v: 'Mike', f: 'Mike' }, '', 'The President'], [{ v: 'Jim', f: 'Jim Vice President' }, 'Mike', 'VP'], ['Alice', 'Mike', ''], ['Bob', 'Jim', 'Bob Sponge'], ['Carol', 'Bob', ''] ]"; I'm then passing this variable into Google's function: google.load('visualization', '1', { packages: ['orgchart'] }); //google.setOnLoadCallback(drawChart); function drawChart(json) { data = new google
