Display tooltip on mouseover in the Highchart Stack Column Total - javascript

I was looking at this highchart stacked column - Highchart Demo
and I'm wondering if it's possible to have a tooltip when you mouse over the total stacked label.
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold'
}
}
I wanted to achieve something like this - See Image here.
Note: I wanted to have a tooltip on mouseover the Total Stacked Label not on the column series.

You can use a custom-events plugin which allows to cache events on stackLabels.

how to customize tooltip in Chart Js?

I want to customize the label of the tooltip on chart js. I just want to show as bold the value of portfolio (+2,5%).
I found this example:
https://jsfiddle.net/nosensus/hhcyhjf9/
When i apply it, my tooltip is always on the left bottom, not on the chart.
How can fix it? I am using Chart.js 2.9.4 version and developing with Angular.
tooltip of the chart should be like this
Put the text you would like to be bold between these tags:
<strong>...</strong>
Like below :
tooltip: {
trigger: 'item',
formatter: '<strong>{a}</strong> <br/> {b}:{c}'
},

How to position tooltip when moving along y-axis?

When I try to hover mouse along y-axis I observed that the tooltip is at the top but the point selected is at the bottom of the graph. This is because the point below might be the second point when we hover along the x-axis.
How do I make highcharts transverse points along the y-axis ?
Note: It is not a shared tooltip
I have tried setting the following attributes in the tooltip:
followPointer: true,
followTouchMove: true,
That is because of the default value of the findNearestPointBy option, which is 'x'. You can set it to 'y' or 'xy':
series: [{
findNearestPointBy: 'xy',
...
}]

Highcharts tooltip between series points

Using this jsfiddle for example, I want to be able to mouse over any position on the spline and show a tooltip presenting x and y, vs. only showing a tooltip for the predefined series data points as it currently works. Is there such an option with Highcharts?
Only thing I see in the documentation would be followPointer which keeps the tooltip on the pointer but the series data points are still selected.
series: {
tooltip: {
followPointer: true
}
}

Formatting legend and axis in Google Charts

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?
After some time experimenting, I daresay it is not posible to choose how much part of the words on legend or axis you can show.
However, you can play with their sizes and position so you get -more or less- what we were looking for.
This is what can be done:
legend: {position: 'top', textStyle: {fontSize: 14}}
I've also made the image a little bit bigger so it fits the x-axis without problems (There was also the option of making its text smaller).
So doing this, this is what you get:
Its basically about setting your chart area vs width / height.
width: [yourChoice]px,
chartArea: {width: '50%'}
ref https://stackoverflow.com/a/6870732/661584
Also as #ArcDare says using the other available styling options such as font size etc
For optmized chart area,
chartArea: {'width': '90%', 'height': '60%'},
legend: { position: 'bottom' },
hAxis : { textStyle : { fontSize: 10} },
vAxis : { textStyle : { fontSize: 10} },
The trick is setting axis textStyle fontsize will enable better placement of legend on the bottom of the chart as the chart Area is about 60-70%
Feel free to use my custom Google Charts plugin which creates both chart and table.
