well I spent this week fixing various bugs and polishing some details. One of the more significant achievement was more sophisticated tooltip generation. Now it should work on any pie chart. Even on one with only one piece.
I have solved the base64 image length problem that I described in my last post. I decided to slice the chart image vertically into as many as 20 parts. In such way one part of a very big chart is under the limit of the base64 image length so it is displayed properly. This added some difficulties for the user when saving the chart to the hard disk. Therefore I have also added an option which allows to output a chart in one single piece.
I have tested various trivial cases for tables and checked if query results work on them. There was some tweaking to be done for these cases.
I have also merged master to my fork. There was only one minor conflict. This actually means that I am not changing PMA code much. I am just adding some new.
Next week I will continue polishing and fixing bugs if any.
