Auto-hide value axes

Type tutorial

Normally, all initialized Value Axes are shown, even if they do not have any visible Series attached to them. This also means that when Series is toggled off, the related Value Axis will remain. This tutorial will show how we can toggle axes off together with Series. The problem Let’s take a simple multi-series multi-axes […]

Handling axis zoom events via API

Type tutorial

Any axis in amCharts 4 can be zoomed. And sometimes we need to know when that happens, as well as the range of the new zoom. This tutorial will walk through all the necessary information to make that happen. This works a bit differently on different axis types, so we’ll explore them separately. Catching zoom […]

Column labels as categories

Type tutorial

This tutorial will explain how individual column labels (bullets) can be used as Category axis labels. The task During the course of this tutorial, we are going to give a fairly basic clustered column chart a makeup. Let’s do this step by step. Moving categories up First task is to move those year categories up […]

Custom ValueAxis grid using ranges

Type tutorial

ValueAxis is a clever kid. It will try to space out its grid/labels in a way that they come in non-crowded “pretty” increments, e.g. in 10 incremental steps. But what if we want to show custom step increments, like every 25? This tutorial will explain how to do that. The task Here’s a very basic […]

Stacked Axes

Type tutorial

This tutorial will introduce you to a powerful concept of “axis stacking”. What is it? amCharts 4 allows having multiple axes of any type. For example, you can have three series attached to three separate Value axes. In a traditional charts those value axes might be put either to left or right, but they will […]

Modifying big number prefixes

Type tutorial

amCharts’ number formatter has a way of formatting numbers in a variety of ways, including converting to prefix/suffix-based shorter equivalents. This tutorial will explain how you can tweak it according to your needs. The problem Extremely big numbers on a chart can be confusing and wasteful of space: Let’s see how we can fix that. […]

Combining different axis types

Type tutorial

amCharts allows any number of any type combined in the same XY Chart. Below demo demonstrates how you can combine utterly incompatible scales – numeric and date/time – with separate Value and Number axes.

Using “fill rules” on a Date Axis

Type tutorial

This tutorial will show how to highlight weekends on a Date Axis. It will explain how you can use custom function to force your own custom logic in determining what ranges of dates should be highlighted and how. Base chart Let’s take a simple Date-based chart. Enabling axis fills We do have nice clean grid. […]

Show only first and last labels on Gauge Chart

Type tutorial

This quick tutorial will explain how you can limit your Gauge chart axis to showing only its first and last labels. Normally, a Gauge chart axis will show a number of intermediate labels. But what if we want to show only the first and last one? There’s a trick: set axis renderer’s minGridDistance to some […]

Fixed Scale of Value Axis

Type tutorial

Value axes in amCharts 4 will automatically adjust their scales to fit currently shown Series’ values as best as possible. This means that scale may, and probably will, change when you zoom/pan the chart, or toggle some series. This tutorial will show how you can easily “lock” the scale in place. Adaptive scale Here’s how […]
