Editing tooltips in Highcharts C# code: A step-by-step guide

I am working with a Highchart basic bar graph and I am looking to customize the tooltip.

Currently, when I hover over the bars, it displays the percentage values that I have inputted in the seriesData.

What I am trying to achieve is to incorporate a Count as well. I have come across the 

.SetToolTip(new Tooltip {
    Shared = true,
    Formatter = @"function() { return this.whatever; }
}

which seems to serve this purpose, but I am unsure about what this refers to or how I can integrate my own variables from C# code into it.

Answer №1

FormatOptions = { headerStyle = "<b>{series.name} </b> <br>", pointStyle = "<b>{point.y:,.0f}%</b>" }

To enhance the functionality of your formatter, it is essential to include necessary properties. headerStyle is typically used for labeling the title of your widget (e.g., Product name, Location, etc.). pointStyle specifies the output string/number displayed when hovering over a specific widget. Refer to the example here.
