How can I customize my barchart datatips in flex? The transparent background of them is too dark to see any of the text in them.
In your chart, there's a property called dataTipRenderer where you can create your own custom datatip. Look here for more information.

I have figured out how to create custom html tooltips by using roles via googleVis. I can easily modify the content using html but I cannot understand how I can control the tooltip box itself.
My problem was generated because some of the custom tooltips I created are falling outside my chart area and I tried (unsuccessfully) to find a way to control the tooltip position. Idealy I would like to make them behave in the exact same way default tooltips behave in googleVis (always stay withinin the chart area).
When I later implemented the same concept into a line chart I found that I have another problem as well. The tooltip is falling on the line so I cannot see what is the exact point that refers to the tooltip.
Would it be possible for example to keep the callout style of default googleVis tooltip and change the content with HTML?
Additionally, do you know if there is any way to control more tooltip properties like border and background color?

1) when laying out your data, make sure it has columns alternating between, say, data and tooltips, data and tooltips,... that way it is possible to customize tooltips for multiple columns (it does not work if you just append - à la cbind - a set of tooltips columns to your data frame).
Additionally try this http://rcharts.io/viewer/?6644957#.VHcpEkvrdbg
Im trying to add border like in the image to flex charts. I used vertical and horizontal Axis renderers but that method id not proper solution. Guys do you have any idea to achieve this one?
Just put it inside a canvas and give it that colour and required padding.
I have an ASP.Net Chart Control of ChartType "Spline", one ChartArea and one Series (it's a sparkline). I was just wondering if anyone out there knew how I could color the area underneath the line - I can't seem to find the property that allows me to do this without coloring the entire background.
Thanks in advance
You need to have a chart with a ChartType of Area to achieve this type of look (similar to google analytics). I have tried it and it does work although i'm not sure how you might get the line to be one particular colour and the area underneath to be a second colour?

When I hover the mouse above the chart elements, it can show some standard hints. How can I show the tooltips without hovering? Thanks
showAllDataTips property of ChartBase class should get you what you want.
I'm new to Flex...I'm wondering if I can make a flex bar chart display a "texture" instead of a color?

You need to write your own itemRenderer where you can specify the texture instead of colors.
