Column Chart with Item Renderer

Posted on by — 2 Comments ↓

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→

Column Chart with Fill Function

Posted on by — No Comments ↓

When you have a column chart, sometimes you want to change the column colors based on the data. A question in the Flex Forum asked how to alter the column color on each column. To do this, yo need to use the fillFunction on a ColumnSeries to set the color of the fill. One issue with doing this, is how it affects the chart legend. If you use the fills property or the fillFunction to define the fills of chart items, and you want a legend, you must manually create the Legend object for that chart. But, this just gives Continue reading Column Chart with Fill Function→

Continuos Vibrate and Music Alert until Confirmation

Posted on by — No Comments ↓

The main phone application that I support at work gets data pushed to it. Part of the data is a Message Page to notify the technician that they have a service call assigned or needing attention. Due to the nature of the service calls, the technician needs this alert to continually go off until they acknowledge the alert. A while back I changed the pop up message to a global message, which makes the pop up show on all screens, regardless if the user is in the application. Unfortunately, when I created this option, I some how broke my continuous Continue reading Continuos Vibrate and Music Alert until Confirmation→

TextArea auto scroll update

Posted on by — No Comments ↓

There was a question on the Flex Forum about how to auto-scroll a TextArea. You can set the VerticalScrollPolicy to auto or you can add a little code to valueCommit to move the vertical scroller. Since I lost where I created the example of adding the code to the valueCommit, I decide to remake the example to show the difference. Both text areas are updated every 10 seconds with a random generated sentence, based off of quotes from Mark Twain. The left TextArea box uses the VerticalScrollPolicy set to “auto” The right TextArea box uses the valueCommit code to move Continue reading TextArea auto scroll update→

Date Sort in a DataGrid – the easy way

Posted on by — No Comments ↓

While trying to give suggestions to a post on the Flex Forum, I modified my Simple Data Grid to include a column for a Date. The poster had an issue with sorting the column with dates in it. My guess is, the Date value is actually a String object. It really isn’t very hard to create a Date from a string, just parse out the String and feed the appropriate date times into the Date object. Here is how I create the random date value. Since I insert the value into the item Object as a Date object, the sort Continue reading Date Sort in a DataGrid – the easy way→

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→
