Dojo, Now with Drawing Tools!
Listing 4. Drag-and-Drappable Dominoes
Perhaps the ultimate test of an API is a few good examples of what you can build with it. One of the ultimate demonstrations of gfx's flexibility and power is Dojo's charting library, another DojoX subproject. A comprehensive introduction of the charting library would entail an article of its own, so until that time comes, you can find some great documentation on Dojo charting from the Dojo Key Links page. And, of course, you always can read over the source, which is located in the dojox.charting module of the toolkit's source code, if you want to get an idea of how much work goes into aligning labels, drawing tick marks and so on.
In addition to equipping you with many of the basic charts you'd want to use in a Web application, charting recently got a boost with a number of cool new features, including event support so that custom tooltips and animations can occur within charts—that kind of visual flair makes all the difference. To give you an idea of just how easy the charting API is to get up and running, consider the code blurb in Listing 5 that shows how to create a chart.
Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
