Distributed Iterative Graph Processing (Pregel).breadth-first, depth-first, and weighted traversals.variable traversal depth between a defined minimum and maximum.following edges in outbound, inbound, or any direction.
In queries you can define in which directions the edge relations may be followed ( OUTBOUND: _from → _to, INBOUND: _from ← _to, ANY: _from ↔ _to). a label naming this interconnection.Įdges have a direction, with their relations _from and _to pointing from one document to another document stored in vertex collections. Its common to have attributes attached to edges, i.e. Graph databases can handle an arbitrary number of these hops over edge collections - this is called traversal.Īlso edges in one edge collection may point to several vertex collections. While simple graph queries with fixed number of hops via the relation table may be doable in SQL with several nested joins, In SQL you commonly have the construct of a relation table to store n:m relations between two data tables.Īn edge collection is somewhat similar to these relation tables vertex collections resemble the data tables with the objects to connect. Coming from a relational background - what’s a graph?

Using Google Docs to Create a Simple Survey FormĪbove you learned how to create charts in Google Docs. The same thing can be achieved with Microsoft excel but I will prefer using Google docs since the spreadsheet is stored in the cloud and can be accessed from multiple computers.
Please note that the chart won’t be available to other office applications if you download it and try with OpenOffice or Microsoft Office. The data reflects the monthly pageviews of Ampercent from May 2009 to March 2010. You can then save the chart as an image in your computer.įollowing is a sample chart made using Google docs spreadsheet. Hit “Save chart and the chart will be embedded in the spreadsheet right away. You can choose to show the legend on top, right, left or bottom of the chart.Ħ. In the next step, enter the labels of the horizontal and vertical axis and give your chart a name. Remember to group data by rows or columns according to your need.ĥ. Simply click on a cell on the spreadsheet and drag the cursor to make a selection. Next, select the range of data which you want to use in the chart which you are going to create. Select the “Type” and the “Sub Type” from the available optionsĤ. This will open the “Create Chart” editor window where you can select the type of hart you want to create. Click “Insert” from the “Menu” and select “Chart” from the options.ģ. Enter your data in columns as shown belowĢ. Open Google docs in your browser and create a new spreadsheet. (Tip: Use Google docs as a Blogging tool) How to Create Charts and Statistics using Google Docsġ. Later, when you want to add, edit or remove data from the chart, just edit the spreadsheet and the change will be automatically reflected in your chart. Google docs has a slight edge because you can store the data in an excel spreadsheet, create the chart and download the image in your computer. You may lose the data used in the chart, if you haven’t saved it in an excel spreadsheet.
After some weeks, if you want to modify the chart – you have to start all over from scratch. You head over to a website which lets you create charts and create the chart as usual. Google Docs Vs Web Based AppsĬonsider you are creating a project report and want a line graph from a set of data. Web based apps are great and offer great designs and patterns but there is a little problem with the data and recursive editing. There are web based tools to create pie charts, bar graphs, Venn diagrams, Flow charts and other graphical representations. Use Google Docs to Create Pie Charts and Graphs
