I'm looking for an answer similar to a previous question:
Link: chart js tooltip how to control the data that show
But I need a solution for a Line Chart via Chart.js. I'm wanting a line chart with multiple lines and I would like each point to return only the data for that point in the tooltip. By default the tooltip returns data in a group for each point at the index you hover over. So I would want each point to only return it's data and have it's own tooltip box.
See default example of line chart : http://www.chartjs.org/docs/#line-chart
It would also be nice if I could have all the tooltips displayed by default and not triggered by a mouse hover.

I'd like to arrange tooltips to NOT overlap AND always be visible on a amcharts4 scatterplot chart.
The documentation reference
https://www.amcharts.com/docs/v4/concepts/tooltips/#Making_cursor_arrange_tooltips
A sample implementation showing that the tooltipText is placed on the series is not providing the needed effect:

The result needed is something like this:

I have a stacked bar chart as follows:
I want to draw a horizontal line that goes through all the bars of a specific color on hover. Basically, if I hover on the following purple/mauve color, I want the following:
I looked alot in online as well as the documentation, but couldn't find anything.
Any help is really appreciated; thank you!
In theory you should be able to pre-render 5 line charts in addition to your stacked bar chart. Give each line chart a unique id or class html attribute, and each segment of a specific color needs a corresponding html classname, eg 'chartSegmentPurple' (actually it would be better to name the class based upon what the color represents, eg 'chartSegmentEconomicInequality'). Keep each line chart hidden. Give your chart an event listener for hover, then in the event handler get the classname. Use the classname to make visible the corresponding line chart.

There is a very nice graph and pie chart under Investment Decision-Making in 2016.
I know it is highcharts now. I want to write something similar. But I can't find any chart type similar in its document.
Could you tell me what kind of chart it is? And how to put different data items inside the bubble.
It looks like a combination of line, bubble and pie series.
Line series (alternative: scatter with lineWidth > 0) lies under the bubbles. All interaction with this series should be disabled (hover state, tooltip, etc.).
Text inside the bubble is data label (dataLabels.enabled property should be set to true). You can manage its content in dataLabels.formattercallback function.
You can handle showing/adding pie (donut) charts in plotOptions.bubble.point.events.mouseover callback function. Text in the middle of a donut can be rendered via SVGRenderer.text().
All options that I mentioned can be found in the API: https://api.highcharts.com/highcharts/
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 have implemented the chartjs. And used piechart. Currently tooltip shows on hover. Is there any way to show the tooltip by default?
As I can understand, you want to always show a tooltip for a given data segment
You can use following code snippet:
var pieChart = $("#chartContainer").dxPieChart({
dataSource: data,
series: {}
}).dxPieChart("instance");
pieChart.getSeries().getPointByArg("Second").showTooltip();
