i have a good reason to sort of revive my PHP programming again.
There are not many things i didn't do with PHP yet, but i need help with charting.
It's not hard to create the data, but i ceased to find a library that easily lets me display a simple chart like this:
The line is representing non-zero values, positive and negative, but the differnce to zero should be colored (red for negative diff, green for positive).
Any hints or tips?
Thanks
EDIT:
For now, it looks like the Highcharts JS API will do.
Using the "area" type of Graph, setting css properties .highcharts-point and .highcharts-graph.highcharts-negative to the desired colors does the trick.
