Usually a graph interpolates linearly between two points, but sometimes a value can only accept certain values and stick to them until the next point arrives. The result is a discrete graph that moves in steps. It is like a continously bar graph.
I added a new parameter $Discrete to the function drawLineGraph() which could be set true or false. If set to false (default), the line graph will...

pChart requires libgd >2.01 due to the function imageftbbox(). This library is not available on many systems and sometimes it cannot be updated.
So this patch replaces the function imagebftbbox() with imagettfbbox(). This makes pChart compatible with libgd 1.8.4.

Hi,
The documentation on the web site looks great and is very good to understand and use pCharts. Nevertheless it seems a little bit outdated. I found some new functions and parameters in the source code but no documentation at all.
What documentation system do you use? Do you use a tool or do you manage your documentation manually? When I contribute a patch, I would like to update the docum.

Hi,
Calling drawLineGraph() and relatives with a pData structure set-up for a XY graph, will loop forever with CPU=100% (until the PHP compiler stop the process).
I haven't digged too far into this problem but a validity test with warning message or skipping the series marked as X should fix the problem.
Best Regards
Matthias.

Hi,
Passing a negative value to ToCurrency() will have weird results. Furthermore it adds zeros even in front of numbers below 100. That looks really strange. Last but not least it will ignore locale settings and produce only anglo-american output.
Currently I use the standard number instead of currency to get arround these problems.
I haven't tested it yet, but the function ToMetric() se.

Hi,
The php suffix will identify the files as PHP code and some editors rely on it (VIM for example). From the functional point of view this chance is not necessary but it would make life easier and my syntay highlighting will work again. :-)

This is a very good idea and should be extended to any hard-coded paths in the code like tmp/ and cache/.
Many web server installations won't allow writing in the web area so configurable path names are manadory.
