Is it possible/how easy is it to produce charts in Rev (without any 3rd party add-ins) ? The charts would be very basic bar charts based on small amounts of data.
TIA

The short answer is there is no library for this. Sample stacks have been contributed by various persons. For instance, Altuit's chart wizard. There was a plotter test contributed by Klaus Major (here on the list, he may chime in).

If you have studio or enterprise, then a fast and easy solution is to use altBrowser to send data to this very nifty javascript library:

chartlib @ thumbstacks.com

Otherwise, charting is only about manipulating the size of rectangles or drawing lines on the interface. All can be done easily. It only depends how sophisticated you want your graphs to look like.

Graph and Table Objects by Kenneth L. Simons

"I've created enhanced graph and table objects that Runtime Revolution programmers can use to facilitate line graphs, scatter plots, tables, and spreadsheets (latest update: 18 December 2006). These objects are easy to paste into any Revolution project, and the file includes extensive documentation and examples. Both objects were originally written for MetaCard and were updated for Revolution, and I have not tested certain properties in Revolution, so if you experience any problems then please let me know."

Thanks marielle - I'll look into all your suggestions

Charts in LiveCode can be created using ChartMaker. The wizard quickly sets up the data and the display settings and it really is a 'point and click' solution. You can also script charts in your own work using css-style keyValue pairs to define the data display. Full documentation is built in with tips, examples and the syntax reference, and there is a dedicated support site of help sheets, video tutorials and archived documentation.

What else can you do? Drag and drop data from Excel or any tab-delimited document source; restore old charts for modification, export to pdf, png, the clipboard or as a fully functional LiveCode object; display drop shadows, tinted gradient fills, trend lines, data subsets... the list goes on!

There is a free 30-day trial and the licence includes personal and commercial use.

ChartMaker is available in the RunRev store.

There is also ChartsEngine, which also is sold on the runrev store page, and has it's own sub forum here:
