This is just a highcharts-canvas-tools module copied from highcharts v0.1.7. This package is generated for simplicity of use.
npm install highcharts-canvas-tools --save
The package expects that global
Highcharts variable is set.
It also doesn't export anything.
Then just require the package if you use common.js
Or include the script in your HTML file.
<script src = "node_modules/highcharts-canvas-tools/index.js">
The code for generating the modules is in this repository
Issues with the way modules work should be reported to the Highcharts repository
Issues with the way modules were generated should be reported to publish-highcharts-modules repository
