How to use chart js library in Magento 2

Spread the love

In Magento 2, you can add a chart to an admin grid to display graphical data representation using the Chart Js Library. Here’s a step-by-step guide on how to do this:

Step 1:

Certainly, if you have a custom module named Bluethink_AdvanceReports, you need to include a JavaScript library file named lib-chart.js under the path view/adminhtml/web/js/, you can follow these steps to properly include the JavaScript library in your module:

				 * Right, this is really confusing and there is a lot of maths going on here
				 * The gist of the problem is here: https://gist.github.com/nnnick/696cc9c55f4b0beb8fe9
				 *
				 * Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
				 *
				 * Solution:
				 *
				 * We assume the radius of the polygon is half the size of the canvas at first
				 * at each index we check if the text overlaps.
				 *
				 * Where it does, we store that angle and that index.
				 *
				 * After finding the largest index and angle we calculate how much we need to remove
				 * from the shape radius to move the point inwards by that x.
				 *
				 * We average the left and right distances to get the maximum shape radius that can fit in the box
				 * along with labels.
				 *
				 * Once we have that, we can find the centre point for the chart, by taking the x text protrusion
				 * on each side, removing that from the size, halving it and adding the left x protrusion width.
				 *
				 * This will mean we have a shape fitted to the canvas, as large as it can be with the labels
				 * and position it in the most space efficient manner
