It's quite logical, but not the effect I hoped to achieve. Besides, as you can see, the direction the gradient is taking is also not very logical or balanced. Therefore the heatmap becomes less reliable.\r\n\r\nI hope you get what I'm saying! \r\n\r\nDo you know anything I can do about it to make the heatmap more balanced and more smooth?\r\n\r\nThanks!\r\n\r\n![temperaturmap](https://user-images.githubusercontent.com/58214303/69622735-d2932a00-1041-11ea-8c04-8331064e0786.png)\r\n\r\n\r\n","author":{"url":"https://github.com/rikkertje-dap","@type":"Person","name":"rikkertje-dap"},"datePublished":"2019-11-26T10:49:01Z","url":"https://github.com/optimisme/javascript-temperatureMap/issues/6"}
