Chart scaled - can this be turned off

if i'm adding a chart to the layout allowing it to strech when resizing the window this will cause the labels of the axis to get stretched/scaled. having the text in a fiexed font would be nice - if the font has to be scaled smaller or bigger this would be ok - but please do not scale my labels only...

Re: Linechart with mouse-draggable areas

ok, found the solution by myself - but it's a little bit tricky: - for the color fields i just added a XYAreaRenderer - the draggable lines were not very easy: first of all you need a entity for a mouse-listener. that's why a line chart with two points and a line inbetween doesn't work. two things w...
