30:T544,md ` --- #### About this Project There are only a few things I care about in a weather app, in order of importance: 1. What's the weather like **right now**, and in the **next few days**? (I live in Seattle.) 2. What's the temperature like in the next few days, **relative to one another**? 3. Will there be **frost on my windshield** in the morning? (I hate scraping.) 4. On the rare occasion, I'd like to know the **UV rating or how windy** it is (based on *gust*), and when will either improve. Moreover, it must be stated in layman terms (for example, I don't know the diff b/n 5mph winds and 15mph winds). That's what I'm trying to do with this weather app. Additional things to note: - Chance of rain is shown only when it's above 25%. - Black marks underneath temperature are the dew points; it's only shown when it's less than 32 degrees, and when temperature is less than 35. - The closer the dew point is to the temperature (the darker the lines will be) the more likely there will be **frost on the windshield** in the morning. - (This is overly simplified, but it's my first stab at predicting frost.) #### Credits - Powered by [Dark Sky](https://darksky.net) - [Weather Icons](https://github.com/erikflowers/weather-icons) for... well, you know - This is an ongoing [DuckDuckGo](https://duckduckgo.com) Hack Days Project `31:T5801,// index = daily index function drawWeather(index) { var height = padding.height; var temp = { // to be set later: max: '', min: '' }; const mask = { id: "mask" + index, expandid: "maskexpand" + index, cornerradius: 5, x: padding.l, y: padding.t, width: width - padding.l - padding.r, height: height - padding.t - padding.b } const weather_midpt = (height - padding.t - padding.b)/2 + padding.t; const weather_midpt_text = weather_midpt + 1; var xScale, xTempScale, xAxis, xTempAxis, yScale, yPrecipScale, yWindScale, frostScale; var rightnow = new Date(); // not dynamic // This day's data.
