Stacked Column Chart with Line Series

Posted on by — No Comments ↓

On the Flex Forum, I was attempting to help someone find their issue to a Stacked Column Chart with a Line Series. The y-axes values were not corresponding with the data being provided. This seemed like a glitch and I even attempted a work around by finding the minimum and maximum values. Finally, after looking at the Stacking Columns example and the Multiple Axis Example, reconstructed the chart using the static objects instead of dynamically creating the chart. From there, I recreated the chart items in a function and determined that the first issue the poster was having was building Continue reading Stacked Column Chart with Line Series→

Find minimum or maximum value from Array

Posted on by — No Comments ↓

Browsing through the questions at the Adobe Flex forum again and came across one about having an issue with the Y-axis display on a dual-Y axis column/line chart. I’m not sure I gave the answer the poster was looking for, but my guess was that the minimum and maximum values for each LinearAxis was not set. You could set them to static values, but that wouldn’t be too useful. So, I did a quick search for some code to find the max value of an array and then modified it for AS3. — update — There is apparently even an Continue reading Find minimum or maximum value from Array→

Spark LineGrid Component

Since I had a day off, I decided to work on converting my old Flex Examples to the new Flex 4.  As stated in a previous post, the new Flex 4 breaks Degrafa and Degrafa seems to be defunct now.  Most of the drawing functions are handled with spark and sprite functions, but little things like arcs and line repeaters are not.  So where before it was easy enough to create a repeating line in Degrafa, now I have to do a loop to create the lines needed.  Well, in this case, instead of drawing lines, I’m drawing rectangles.  While Continue reading Spark LineGrid Component→

Autoscroll Textarea

One of the ways I like to debug my Flex applications is putting a TextArea item that is visible when needed to display certain items that usually would be display in a trace.  The benefit of this little trick is that I can see what is going on without having to go through Flex Builder.  Also, I happened to create a web service debugging application and it displayed the error and result text from the web service.  When displaying either debug or general result information, it is helpful if the TextArea scrolls up to show the latest information added.  I Continue reading Autoscroll Textarea→

New sprite Egg Timer

Posted on by — No Comments ↓

At work I upgraded to Flex 4.5 and started updating one of my projects.  I started running into errors with my components that used Degrafa.  Apparently the Degrafa group has stopped working on updates and code in Flex 4 has broken the arc and wedge drawing utilities.  This causes a problem with my Egg Timer component, because it relies on the wedge or arc for the display.  I decided to use the new functions of Flex to create the timer.  Unfortunately, Flex still doesn’t have it’s own wedge or arc drawing utilities.  It does have a curveTo method as part Continue reading New sprite Egg Timer→

Horizontal Slider and List synch

Posted on by — No Comments ↓

As I stated in a previous post, I am working on a little project for work that dealt with including arrays inside of arrays.  Part of this also had me putting lists inside of lists.  The layout of one of the display has an Accordion navigation control with a HorizontalList, that also contained an accordion with it’s own HorizontalList.  I am using the horizontal list to scroll through main items with sub-items below.  On top of this, I am creating the HorizontalList, the HSlider and the Accordion controls all dynamically. The first part of setting up the slider and list, Continue reading Horizontal Slider and List synch→
