You might already know that Google Search makes a handy calculator. Just type any calculation into a Google search box, and the answer is computed for you. Earlier this week, we added an even cooler, more powerful feature. Now, when you type a function, you’ll see it graphed.


As you can see in this image, you can graph more than one function at a time by separating them with commas. Once the graph is drawn, you can zoom and pan to see the sections and details you want. And the Google colors are a nice touch.

In other calculation-related news this week, the Hubble Space Telescope counted to 10,000. That’s the number of published scientific papers based on data gathered from Hubble. Although the telescope was launched back in 1990, it’s said to be in great shape and is taking great pictures, thanks largely to frequent service missions by astronauts. That should inspire you to change the oil in your car.

Finally, here’s one especially for you babies out there, and for those who know or are related to babies. The Nerdy Baby coloring book for very young scientists looks like a great way to nudge very small kids toward a proper nerdy upbringing. And when you’re not coloring, you can spend some time this weekend coming up with cool functions to graph on Google Search.


Fridaygram posts are just for fun. They're designed for your Friday afternoon and weekend enjoyment. Each Fridaygram item must pass only one test: it has to be interesting to us nerds (sometimes including nerdy babies).

At Google Code search, we've seen distributed version control systems get more popular. Linux has been using one for several years and several large open source projects have migrated to using one in the last few years. In recognition of that, we are now announcing that we crawl Git and Mercurial repositories.

For Git, we now crawl repositories hosted by several public git hosting sites including GitHub and repo.or.cz. In addition to that, we also crawl Android, Chromium and Linux code. Feel free to provide feedback to let us know how we're doing.2013, By: Seo Master

We're happy to announce the Google Visualization API Library for Google Web Toolkit (GWT). This has been a requested addition to GWT for some time now on the developer forum and we are excited to make it available.

You can now utilize the visualization and reporting capabilities of the Google Visualization API while writing native Java code for your GWT applications and enjoy the best of both worlds. The library includes wrappers for many of Google's visualizations, such as Bar Chart, Annotated Time Line, Map, Motion Chart, Organizational Chart and many others. We have marked all the visualizations that are currently supported by this library in the Visualization Gallery.

The library also includes classes that enable you to easily wrap any existing Visualization API-compliant visualization in GWT so that you can access it from Java complied by the GWT compiler. So if you want to wrap your own visualization or the nifty Piles of Money visualization, you can easily do so.

Lastly, the library includes a class that makes it easy to write new visualizations in GWT-compiled Java and make it available as JS for general use in the Visualization API. This is cool if you've been itching to contribute new visualizations but prefer coding in Java.

Here is example code that draws the well known Annotated Time Line chart in Java using the new Visualization API Library:

UPDATE: Changed the code font size to fit on one line so you can copy & paste

package com.blogpost.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.Window;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.visualization.client.AjaxLoader;
import com.google.gwt.visualization.client.DataTable;
import com.google.gwt.visualization.client.Query;
import com.google.gwt.visualization.client.QueryResponse;
import com.google.gwt.visualization.client.Query.Callback;
import com.google.gwt.visualization.client.visualizations.AnnotatedTimeLine;


public class BlogPost implements EntryPoint {
  public void onModuleLoad() {
    AjaxLoader.loadVisualizationApi(new Runnable(){
      public void run() {
          Query query = 
                Query.create("http://spreadsheets.google.com/pub?key=pCQbetd-CptH5QNY89vLtAg");
          query.send(new Callback(){
           
            public void onResponse(QueryResponse response) {
              if (response.isError()) {
                Window.alert("An error occured: " + response.getDetailedMessage());
              }

              DataTable data = response.getDataTable();
              AnnotatedTimeLine.Options options = AnnotatedTimeLine.Options.create();
              options.setDisplayAnnotations(true);
              RootPanel.get().add(new AnnotatedTimeLine(data, options, "800px", "400px"));
            }
          });
      }}, AnnotatedTimeLine.PACKAGE);
  }
}

This code draws the same visualization that can be seen in the example for Annotated Time Line in the Visualization Gadget Gallery. Both get their data from Google Spreadsheets, only this code does so in Java instead of Javascript or as a Gadget.

Enjoy!2013, By: Seo Master
