问题 I found the following code online and would like to adapt it to my existing code. Here's the code to show/hide data series on click I found: http://jsfiddle.net/asgallant/6gz2Q/ Here's my Adaptation so far: function drawChart() { var data = new google.visualization.arrayToDataTable([ ['Draw', '1997', '1998'], ['1', 1236777, 1408007], ['2', 834427, 572882], ['3', 2164890, 1614181], ['4', 1893574, 3897171], ['5', 2851881, 673906], ['6', 359504, 630853] ]); // Instantiate and draw our chart,

问题 I'm new with Google Charts and I am not able to obtain a fine result with the texts surrounding the graph. This is how my chart looks: As you can see, it does cut both Horizontal-Axis and Legends, so the final result is not as good as It could be. Is there a way to solve this? I've been reading the official documentation and some posts from here, but I haven't found the way to do this. Recap: How do we modify the legend or the axis texts so they are fully visible? 回答1: After some time

问题 I have a two lists of postcodes (in R)...one of children's addresses with their academic score and one of schools... i would like to be able to get the closest school for each child...so presumably a calculation of distance would been needed between postcodes by converting to long and lat values? And then I would like to be able to plot on a google map all the children per school...and see if the children who live closer to school get better grades...perhaps ploting schools a different colour

问题 Every time I use Google Charts' Table the google loader loads a http://ajax.googleapis.com/ajax/static/modules/gviz/1.0/table/table.css which always and almost kills my bootstrap css, and i't pretty annoying at 2AM. :) Note: I can't modify the table.css file. Do you know any method that can prevent the loading of the CSS file? Thanks for the help. PS: Yep, I've tried with JS, but the table recompiles on switching page, so i should replace the table 's classname every time on paged. 回答1: As

问题 My app charts 4 data series using the google chart api. The controller loads an array, the view has the google chart javascript to draw the cart. It works if the array is full populated, but of course sometimes a data series is missing a few points and I cannot see how to specify 'missing' data points in a series so arrayToDataTable() javascript function will know to provide the 'null' data for that point. In my controller, I load an array with data (fully populated array example): @typed

问题 I have to create a google area chart that has one line with the background fill but then also have additional lines that overlay it with no background fill. I can't figure out how to do this and am hopeful someone here knows. In the example image below the dashed blue lines are the ones I'm trying to figure out how to create. 回答1: you can use a ComboChart, with both line and area series. see following working snippet... google.charts.load('current', { packages: ['corechart'] }).then(function

问题 How can I keep zoom-in, zoom-reset functionality after chart redraw? It seems like these options stop working after I use zoom-in option and then redraw the chart. What am I missing? My code is: google.charts.load('current', {'packages':['corechart','table']}); function drawChart(data, chartType) { var w = document.getElementById('chart_div').clientWidth; var h = w * 0.5; // Instantiate and draw our chart, passing in some options. var chart = new google.visualization[chartType](document
