I'm using Google Charts (Javascript) to render some charts on my web application. Now I simply want to add a text label on a specific position on the chart (bottom right). For whatever reason there is nothing to be found on the internet about the subject.
An HTML overlay isn't gonna work as I also want the text to appear if I get the chart as an image with the following code:
google.visualization.events.addListener(chart, 'ready', function () {
var imgUri = chart.getImageURI();
$('#chart_img').attr('src', imgUri);
});

I'm actually developing one app using the javascript plugin chartjs (on the framework Symfony 3) and I realised that when we create a chart before the page it's ready, the legend it's correctly shown, but when I create other chart doing click on a button (after document.ready) the legend it's hidden.
To illustrate my problem, when I do :
// the chart is draw with the legend
drawChart();
// The chart is draw without the legend
$(document).ready(function() {
drawChart();
});
Have you ever meet this problem ? Is there a solution to solve this ?
Big thanks to all who takes time to help me !
I am using google timeline charts for a project .
The timeline is being updated every some seconds(randomly) adding new lines in the graph .
When the lines are being added to the timeline tooltip pop up does not disappear from the screen when mouse moves over to other lines. The tooltip is sticky on the screen and this gives an unpleasant user experience
Any solution for this?
Thanks
So I found the solution ,
container = document.getElementById('' + youridentifier + '');
chart = new google.visualization.Timeline(container);
chart.draw(dataSet, options);
Every time you "redraw" the google chart you have to create a new visualization object .
If youre using Bootstrap tooltips you can hide them all with a JS call.
$(someJQuerySelector).tooltip('hide');
I am attempting to replot a chart when the user selects the tab to display the chart(initially it is set to visibility:hidden). Once it plots the graphs again, I don't see any of the lines or bars in the graphs, I only see the legend. I want to see all of the data again. When I don't hide the element and just plot it, it works fine, but I need to hide the element so that data can be grouped together in a logical order.
Here is the code I use to plot the charts while it's hidden, jqPlots is an array which contains the variables used for plotting.
var plot = $.jqplot (DATA GOES IN HERE)
jqPlots.push(plot)
Then within the handler for displaying the div I have
for(var i = 0; i<jqPlots.length; i++)
{
jqPlots[i].replot();
}
I have a bunch of divs that are initially hidden, and I attempt to draw a plot within those hidden divs. I've realized that you can't draw within a hidden div, so what I've done is that when the user clicks the button to display the div, I replot the graph(along with drawing it when it's hidden, but I receive this message in Google Chrome's Developer Tools "Uncaught Error: Target dimension not set" and the plot does not display.

I made a chart using Google Visualization's ColumnChart like this.
It's basically a stacked column chart using 3 x 7 matrix. In every bar, I remove the data for two other rows.
My problem is how to make the yellow bar (or other bar) looks like it has been clicked from the start using the Javascript code. Just like below.
*Notice the light border in the yellow bar.
You can programmatically select a bar by calling setSelection() on the chart. This can only be done after the "ready" event has been fired, i.e. you can set the selection upon this event being triggered as follows:
google.visualization.events.addListener(chart, 'ready', readyHandler);
function readyHandler(e) {
chart.setSelection([{"row":1,"column":1}]);
}
Here's a working example where we programmatically select the second bar after the chart has been drawn: http://jsfiddle.net/FFEZT/
