I was unable to draw a simple line graph when i
submitted an array where the data was "1, 1, 1, 1, 1".
Division by zero in panachart.php on line 257
occured. This was just on a test system so i wont be
affected by it later but took me a while to under stand
what was wrong.
Simply changing the data to "1, 2, 1, 1, 1" prevented
the error from happening and the graph was drawn.
