Base chart The following chart was set up to show all labels, regardless if they are overlapping. categoryAxis.renderer.minGridDistance = 30; categoryAxis.renderer.minGridDistance […]
tutorial This short tutorial will show how you can make your XY chart more readable by introducing a fill between each second set of grid lines.

Sometimes, when there’s enough space, and the range of values is not great, the axis will throw in intermediate non-integer values as labels. This tutorial will show how to hide those non-integer labels. Base chart Let’s use this bar chart as an […]
tutorial This quick tutorial will show how you can use Axis Ranges on a Radar chart. If you are already using Radar chart, you know that its essentially bent XY chart. Which means it has X and Y axes, that can be one of the three types: Value, Date, or Category. This also means, that whatever […]

tutorial This tutorial will explain how you can set up your charts to initialize pre-zoomed. Prerequisites This tutorial relies on event handlers. We recommend reading up on how events work in amCharts 4 in “Event Listeners” article. Reference chart Let’s start off with a simple date-based chart: Setting up pre-zoom There currently are no properties on […]
tutorial This tutorial will explain how you can deal with very long axis labels, by wrapping and/or truncating them. Prerequisites If you haven’t done that already, we suggest you take a look at the “Positioning Axis Elements” article, which explains the principles about configuring Axis elements, including the concept of “axis renderer”. Moving forward we will […]
