$ cd ./nodejs-image-generation-utility
            

To run the example you have to install dependencies. Run the following command:

Notice! AnyChart NodeJS module requires ImageMagic to create JPG and PNG images. Visit Image Magic install page for details. Note for Windows users: you have to create environment variable as described in Image Magic: Advanced Windows Installation article.

To run the example with defaults you should just execute index.js file with nodejs:


$ node index.js
Written to image.png file
            

Notice! Please refrain from using percent values in chart. In node js DOM emulation there is some problems with this and resulting image may be differ from the planned.
