TAChart Demos

TAChart is Lazarus' powerful charting library. It consists of numerous classes and declarations distributed over some 50 units. New users may be overwhelmed by the complexity of usage, and even experienced charters still find gems from time to time.

TAChart Tutorial: Multiple Panes in one Chart

This tutorial shows how to create a chart with multiple series in their own panes and with their own left axes and one common bottom axis. It was created while checking out the nice "Panes demo" which you can find in the folder components/tachart/demo/panes of your Lazarus installation. Since a second topic is included in this sample project it may be a bit difficult to catch the basic idea. So here we explain how you can do this from scratch.

TemplateApp

Lazarus template application project with full localization. It took me quite some time to create a fully featured application project that could set the language from the system but also had the capability to set the language live from the application itself. Templating is good. It saves time because you don't have to reinvent the wheel and it prevents bugs because what you already have is probably already tested. See /help/index.html or the wiki page for further information.

thumbapps

We believe that free/open source softwares are enough, we don't need pirated softwares on Windows. But most of these aren't portables, or provided by PortableApps.com due to .NET dependencies, 64-bit etc. So we provide what's missing here. Software publisher who wishes their portablized software taken down, can tip us at https://www.thumbapps.org/2014/11/Contact-Us.html or versapps@gmail.com—we might not be able to respond promptly, but we eventually *will* ...thanks for your patience, and sorry for being such a #naughtyuploader ;) Disclaimer.

Vaio DOS

Vaio DOS is the greatest DOS distribution of all the times. You may freely use it for personal purpose on a retrocomputer at your own risk. Either way, I'll appreciate knowing you have found it to be helpful, my dear friend. The distro was tested on the Sony Vaio PCG-VX88 (PCG-551L) laptop. It supports networking, USB sticks, and whatnots. Cheers!
