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 working on adding transition to the line chart, copied a example from herehttp://bl.ocks.org/d3noob/7030f35b72de721622b8, i want the line chart to do transition when the interval happens, like in the example when you click the button the chart will move to left but in my plunkerhttps://plnkr.co/edit/sCJYfXDSjXN1IiFokK1V?p=preview doesn't work, I put the d3 code in angular's custom directive because i have a requirement where graph will be repeated more than 5 times any help is much appreciated
In your update data function, selection of the chart was var svg = d3.select("lineChart").transition();. It should be var svg = d3.select(".lineChart").transition();
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 currently have 2 AMCharts on the same page and a single dropdown with values 2015,2016,2017,2018 in it.
I have followed this example to dynamically update the data in the bar chart
http://www.amcharts.com/tips/dynamically-loading-chart-datasets/
I also have a Pie Chart and would like to update the data with the same drop down but I am not sure how to connect it so that it also updates at the same time.
Any suggestions ?
Just expand the function that changes the dataset of the charts with your pie chart reference.
function setDataSet( dataset_url ) {
// chart2 should be the reference to your pie chart
chart.dataProvider = chart2.dataProvider = AmCharts.loadJSON( dataset_url );
chart.validateData();
chart2.validateData();
}
EDIT:
Here is a working demo.
I'm trying to replicate the trulia's graph with D3.js, but only the main chart (the heatmap) and the daily graph (the graph bar that changes when you hover the mouse over a specific point on the main chart).
Using this example, I've managed to build the main chart with my own data. I also have the second chart. But now I have no clue on how to update this second chart when I hover on a point on main chart.
Essentially, what you're going to have is two different charts with different data. The first chart (the heatmap) controls the other one. Each data point on the heatmap has a day and an hour attribute, which we want to use to control the second graph. To do this, we can use two functions to control the second graph, and then call both of them every time someone clicks on a point.
The first function just needs to build a blank graph for the target day.
function updateGraphDay(newDay){
//Remove current graph and build graph for newDay
}
The second is one that will highlight a certain hour on the bar chart. I'm assuming here that your bar chart is in its own SVG, barGraphSVG, and all of the bars have the class hourBar, and that the data you used to create it has an hour attribute, like the heat map data.
function updateGraphHour(newHour){
barGraphSVG.selectAll('.hourBar')
.classed('selectedBar', function(d){ return d.hour === newHour });
}
Now you just call both of these when you hover on one of the rect elements in the bar chart.
heatMap.on('hover', function(d){
updateGraphDay(d.day);
updateGraphHour(d.hour);
});
I'm using nvd3 for a multi-bar chart, and I'd like to make the chart redraw when the user clicks the other html on my page. I tried using jQuery to select the "Stream0" legend circle on the nvd3 homepage (http://nvd3.org/) and click it using this snippet in the console:
$($('g.nv-series')[0]).click()
For reasons that I hope will be immediately obvious to people more knowledgeable about javascript, nothing happens. Is it something to do with event delegation?
http://nvd3.org/
you can try this:
chart.legend.dispatch.legendClick = function(d, i){
//redraw
};
It will append your own method to the legend; it works for pie chart not sure if works for the line chart;
Maybe there is some help in this. Two charts, one pie, one stack but only showing legends on pie.
The data is not identical but the legends are..
Want to update both on clicking pie legends.
chart.legend.dispatch.on('stateChange.pie', function(d,i){
setTimeout(function() {
stackedAreaChart.dispatch.changeState(d,i);
stackedAreaChart.update();
}, 100);
});
Note: using the ".pie" will extend the (library) stateChange event (not overwrite it)
The other chart stackedAreaChart has to be in the scope.
Note there is a changeState event and a stateChange, best is to look at the un-minified nvd3 js file..
