Column charts with ticks

After having some issues with the Flex Forum due to spamming (not me), I went back on to answer a few quick questions. A question about creating tick lines between the interval lines on a column chart was followed up with setting the number of tick lines between the intervals. The first part of adding tick lines is fairly straight forward. When you create a ColumnChart and add LinearAxis, you can set the minorInterval value, which creates the ticks between the main intervals. After that is set, you can add an AxisRenderer to the verticalAxisRender to adjust what the tick Continue reading Column charts with ticks

Upgrading to Apache Flex

Since I don’t keep as up-to-date with tools at work as I would like to, it came as a little bit of a surprise that Adobe had given Flex over to the Apache foundation as Apache Flex. 2011: Adobe decides to contribute Flex to the ASF The decision is made within Adobe to incubate Flex at the ASF. Work starts on the incubation proposal, on explaining internally what this means, on the legal/IP clearance steps required to donate the code and on recruiting initial committers who will help get the project started. Obviously, I was a little slow on the Continue reading Upgrading to Apache Flex

Color name to uint value

Filing under the “why didn’t I find this before” folder. On the Adobe Flex forums, there was a question about changing the color value of a button based on a switch statement. The user was trying to change the value to “Red”, “Yellow” or “Green”. In the button, the type for color is uint value, so the input needs to be something like “0x990000” for “Red”. I usually just insert in the uint value for a color and not the name, since I usually have to change it. But, this question on the forum got me thinking and searching for Continue reading Color name to uint value

DataGrid Row Move

Another question on the Flex Forum about how to move a selected row on the DataGrid up or down, based on a button click.  The answer is straight forward, but with a catch. When you click on the DataGrid, it will give you an index for the row you have clicked.  The first row in the DataGrid is 0.  If you wanted to simply move a row up and down the DataGrid, then you simply add or subtract 1 from the selected index. Simple enough.  Unless you sort the DataGrid, which throws that out of wack and is pointless.  So, Continue reading DataGrid Row Move

Column Chart with Item Renderer – updated

Okay, it didn’t take me long to get back and do some more fiddling with the Column Chart Item Renderer. I went ahead and changed the static ArrayCollection to a dynamic one, because I was trying to figure out something with Themes and needed a button and the button should do something. The ArrayCollection is fairly simple for this chart, so all I did was create a couple of random values from 0 to 100 and made the “date” value the counter time 10. I set it up so that you can press a button and create new data, which Continue reading Column Chart with Item Renderer – updated

Column Chart with Item Renderer

When doing the Column Chart with fillFunction for a question in the Flex Forum, the poster said that he was trying to do something a little different. Instead of a simple fill, he wanted the fill to be semi-transparent with a solid border. When I looked at the iFill function, it didn’t have a stroke option and it doesn’t seem that the standard column item deals with the column border. My guess was, that an item renderer should be used for the column instead. Within the item render, you can create a rectangle graphic and then adjust the border and Continue reading Column Chart with Item Renderer
