Pen Settings

CSS Base

Vendor Prefixing

Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

+ add another resource

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

Use npm Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import. We'll also process your JavaScript with Babel.

⚠️ This feature can only be used by logged in users.

  // clear out the previous drawings
  // During the next few lines, if you switch the originPos with the pos values, you can get some drastically different results. Right now, this is keeping the position circle in a vertical line by using the originPos x.
  // draw the line in the back
  // then draw the origin circle
  // then draw the position circle
  // Draw the offset text
  // Round it, because on hidpi screens the number is a float.
  drawText(ctx,Math.round(originPos.y-pos.y),originPos.x-30,pos.y,{fillStyle:"gray",font:"16px verdana",textAlign:"right",textBaseline:"middle"})
  .on("mouseup touchend",function(e){
  var pos = getEventXY(e);
  // Write the offset amount
  $(".temp-change").html(Math.round(originPos.y-pos.y)+" Change to temperature")

🕑 One or more of the npm packages you are using needs to be built. You're the first person to ever need it! We're building it right now and your preview will start updating again when it's ready.
