width of value axis / left axis ??!! :-)

Hi there, can someone please tell me how to specify the width of the left (the value) axis ? Say, i want to set the width to 100px, so that it's aligned with some other charts, where i want to set the width to 100px as well .... I am searching and searching and can't find a solution. Thanks, Ulrich

can i somehow set the position of candles not to be centered around the time point, but ending at the time point?

Code: Select all

not like this:


     X
    XXX
    XXX

-----O--------------

but like this: 

     X
    XXX

i don't know if it's a bug, but it's definitely not a feature.
this happens always if you want to chart the same value. as soon as you add a different value everything shows up.

have no solution for this either.

speed of candlestickrenderer

is there a reason why the candlestick chart is really *horrible* slow? Compared with the other chart types, the candlestick chart type draws not reasonable slow ...

is there any way to improve speed?
