In Highcharts, I've been using the dataLabel formatter to return an empty string value for zero values. This effectively hides the label for zero values. However, on pie charts, there is a guideline that points to each pie slice, even if the slice has a zero value. I can't seem to remove these guidelines without directly manipulating the DOM elements.

I'd like to keep the empty pie slices in the chart because I am dynamically updating the chart based on user-manipulated filter criteria, but I would like to hide the guidelines pointing to empty pie slices.

Does anyone know of a way to configure Highcharts remove the guidelines pointing to empty pie slices? I am able clear out the label itself using the formatter below:. When the formatter function is evaluating the value to display, the context has access to the guide-line path element. I was able to hide the guideline by making the following change to the formatter:.

Stay safe and continue achieving your business goals. This tutorial will help you integrate Flexmonster with the Highcharts charting library.

If the chart type that you want to use is not on the list, it is possible to use prepareDataFunction to preprocess the data to fit your preferences. You will see a line chart that displays the same data that is shown in the pivot pivot table instance and it will react to updates. Check out a live example on JSFiddle. The highcharts. The connector has several functions for defining number formatting for Highcharts.

All these functions take the pivot table format object and return the formatting string in Highcharts format. The Highcharts format string is a template for labels with one of the following variables inserted in a bracket notation: valuepoint. Thus, there are four functions in the connector that convert the Flexmonster number format object to the Highcharts format string refer to the Highcharts documentation for more details about the format strings.

These functions can be used in both callbackHandler and updateHandler to define the number formatting for axes and tooltips. Try it in JSFiddle. Table of contents. Integration with Highcharts. Supported chart types Flexmonster supports the following Highchart types: area demo arearange demo areaspline demo areasplinerange demo bar demo bubble demo column demo columnrange demo errorbar demo funnel demo line demo pie demo polygon demo pyramid demo scatter demo spline demo waterfall demo If the chart type that you want to use is not on the list, it is possible to use prepareDataFunction to preprocess the data to fit your preferences.

This function uses a connector for Highcharts from flexmonster. The connector extends the Flexmonster API with the following call : highcharts. Connector for Highcharts flexmonster. This object has the following properties : type optional — String. The chart type to prepare data for. If not defined, the API call will return data currently displayed in the pivot table.

Try it in JSFiddlethis sample also illustrates how to define a type for particular series. Set this property to true to display all axes values in the chart as numbers. Default value: false. If the connector does not include the necessary type of chart or if you need to preprocess the data differently, use this function. Specifies what will happen once the data is ready. Additional options can be specified and then data can be passed directly to the charting library.

Highcharts: Enhancing User Interaction on Pie/Donut Charts – Dynamic Connector

Takes two input parameters — data and rawData rawData is passed just in case you need it, for example for defining number formatting in the tooltip.

Takes two input parameters — data and rawData. Takes the pivot table format object and returns the Highcharts format string with the value variable. Takes the pivot table format object and returns the Highcharts format string with the point.Recently, I got a request from a Highcharts user asking me how to improve the user interaction on pie charts; when the pointer is hovered over a slice:.

An arrow appears outside the pie section 2. A text box appears in the center of the donut charts showing the hovered section data. I think this is a good exercise and demonstration to show how flexible and powerful Highcharts can be. In this blog, I will show you how to convert a normal donut chart into the one showing here and you can try the online demo.

First, let starts with a normal donut chart. The following screenshot shows the a default pie chart. As you can see, there are curve lines extending from each pie section to the data label.

In Highcharts, these lines are called, connectors. Internally, a connector is represented as an object with properties and methods. Later we will see how flexible is Highcharts that we can manipulate these connector objects.

Our next goal is to implement an interactive connector that appears when the pointer is hovered over a pie section. That means we need to implement the mouseOver and mouseOut event callbacks and lets dig down to see what inside the point object when we call the callback.

The keyword this is a Point object where the pointer is hovered over the data point. Lets launch a browser console and investigates what lies beneath this object. As we can see inside the point object, there is a connector object embedded inside which contains properties and methods to generate SVG elements. Now we can use this object class to change the connector display and behavior. Lets make all the connectors hidden in the initial display and appears and disappears with mouse pointer actions.

The followings are the changes made to plotOption. First, we initially set the connector color, connectorColorto the same as the background color. Unfortunately, we cannot disable the connector by setting the connectorWidth to 0 because this will remove the connector object inside the callback handler.

The following screenshot shows the first prototype of dynamic connector and you can click here to view the demo:. Our next task is to change the shape of a connector from line to arrow. Here is the code for mouseOver callback:. We first extract the starting coordinate from the original connector SVG path.

Then we reconstruct the SVG path, dinto a triangle using that coordinate. After that we call the updateTransform method to perform the rotation on the triangle.

Finally, we prettify the arrow with a border color. Here is the screenshot of the final prototype and you can see the online demo here :. Our last task is to put the tooltip into the middle of the donut chart. This can be achieved by using tooltip. Here is the final screenshot and the demo link :.

If we don't have enough space for the labels then we don't render them. Labels with the lowest values are hidden first - this can be controlled by point.

Additionally: the function responsible for the dataLabels distribution is Highcharts. You can override it and provide better logic if you have one. Skip to content.

Here you can find an example how it will work then: jsfiddle. Thanks for correcting me. But still I am not getting the desired result Well, right, because that's not how Highcharts draws the connectors.

I would guess the best options are either 1 draw your own connectors with the rendereror 2 modify the Highcharts function that draws the connectors.

Works like a charm! Can you help me? So you would like to get similar connectors to shown in this example? Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name.
