We’ll then grab our canvas element by using the inputted id. This is where we'll place our chart configuration code.įirst, we’ll set up our createChart function that take in an id, the chart data, the requested D3 interpolate color scale, and our color range information.įunction createChart(chartId, chartData, colorScale, colorRangeInfo) Next, we set up our HTML and import a file called color-generator.js which lives in our utils directory.

If you’re using NPM, you can install it via npm install d3-scale-chromatic This library features a wonderful, diverse set of color scales. Next, we will import D3’s Scale Chromatic Library. If you’re using NPM, you can install it via npm install chart.js Chart.js is an open-source Javascript charting library that uses HTML5 Canvas. utils (For helper functions, like color generating functions)īecause we are writing everything in vanilla, client-side Javascript, we will import the relevant packages via a content delivery network.įirst, we will be importing the Chart.js library.

index.html (Where we will write HTML and JS code to create our chart).Here’s an explanation of the important directories and files: What’s worse was that I had so much config and conditional code just for this color data! My chart obviously broke down when there was more data. I made the mistake of hardcoding 6 different color code sets depending on the length of the data (from 1–8 data points). So I ended up being affected by all the cases above. Or, like me, you just suck at color theory (what, red, green, and purple don’t go together?)

If you don’t know how to create those values, you typically go on a generator site like the one mentioned and copy the values into your code. Often times, you’ll find yourself using a completely different set of colors depending on the number of data points you have. A desire to distribute your colors in a “visually equidistant” manner - This palette generator site explains that “visually equidistant” values tend to have different base hues.You’ll have to manually add a color for the new data point. Now an additional data point is introduced, and you have 7 data points.

Data that is subject to change - Imagine hardcoding 6 color values because your dataset has 6 data points.

A ton of data points - Manually selecting colors for this data can be an absolute pain.

Generating colors automatically can be tremendously useful for the following cases: In this tutorial, we’ll be showing you how to use Chart.js and D3’s color scales to create a series of pie charts whose colors are computed automatically.
