Perfect. I went with the ShadowBoxitemRenderer
approach – no noticeable hit on performance at this stage – and it
looks just the same as before in the ColumnChart. Thanks again for your time. From:
flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ely Greenfield In Beta 3, the drop shadow in the columns
has been optimized by attaching it to the ColumnChart directly. To get it back,
you've got two options: 1) set the seriesFilters property of the
CartesianChart to a drop shadow. This will give you a single drop shadow
for the entire set of columns (i.e., the front most column won't create a drop
shadow on the columns behind it, giving the appearance that all the columns are
flattened into one layer). <CartesianChart> <seriesFilters>
<f:DropShadowFilter xmlns:f="flash.filters.*" /> </seriesFIlters> 2) set a drop shadow filter on each series
directly. This will make the front most series cast a shadow on the
series behind it. <CartesianChart> <series>
<ColumnSeries>
<filters>
<f:DropShadowFilter xmlns:f="flash.filters.*" />
</filters>
... 3) set a drop shadow filter on each
individual column. This has the biggest hit on performance, but will make each
individual column pop out. To do this, set the itemRenderer or each column to
the ShadowBoxitemRenderer (this one probably won't add anything to your use
case). ... <series>
<ColumnSeries
itemRenderer="mx.charts.renderers.ShadowBoxItemRenderer" ... /> ... Ely. From:
flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ben Lucyk Works like a charm Ely. I added an alpha=”.8” to
help give it that same look in Brocade.
One question though, where did my nice column drop shadow go to now that
I’m using the CartesianChart and how do I get it back? Thanks, From:
flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ben Lucyk What a great help Ely. Thanks for all the detail! It sounds like you’ve spent a fair
amount of time with this one already!
:) I’ll be playing with your
suggestions tonight and will post my results. Thanks again, From:
flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ely Greenfield Hi Ben. When a set of column series
is clustered, the chart (or columnSet) is setting the columnWidthRatio and offset
properties to do it. So if you wanted to cluster differently, you could put the
columnSeries inside a CartesianChart and set those properties yourself. To figure out how wide each column should
be, you first need to decide how wide you want the total cluster to be, and how
much each column should overlap. Then your formula would be: columnWidth = clusterWidth / (overlap +
(series count)*(1-overlap)); the offset is the offset of the middle of
the column from the middle of the category. given the clusterWidth and
columnWidthRatio, the offset for each series is: seriesOffset(N) = -clusterWidth/2 +
(1-overlap)*columnWidthRatio*(N) + columnWidthRatio/2; So if you have three series, and your
total width is 75%, and the overlap should be 50%, then columnWdithRatio = .75 / (.5 +
3*(1-.5)) columnWdithRatio = .75 / 2; columnWdithRatio = .375 given that, seriesOffset(0) = -.75/2 + (.5)*.375*0 +
.375/2; seriesOffset(0) = -.1875; seriesOffset(1) = -.75/2 + (.5)*.375*1 +
.375/2; seriesOffset(1) = 0; seriesOffset(2) = -.75/2 + (.5)*.375*2 +
.375/2; seriesOffset(2) = -.75/2 + .375 + .375/2;; seriesOffset(2) = .1875; Putting that into practice, the markup
would be <CartesianChart> <series> <ColumnSeries
columnWidthRatio=".375" offset="-.1875" /> <ColumnSeries
columnWidthRatio=".375" offset="0" /> <ColumnSeries
columnWidthRatio=".375" offset=".1875" /> </CartesianChart> (You may need to reverse the order of
those, I don't remember) Ely. From: flexcoders@yahoogroups.com
[mailto:[EMAIL PROTECTED] On Behalf
Of Ben Lucyk Does anyone have some examples or info for styling the
<mx:ColumnChart type=”clustered”> component? I have a client that is interested in
seeing the same “displaced”, overlapping styles for the column
series’ as seen in the online Brocade sample app (Click “Measure
Viewer”). http://flexapps.macromedia.com/flex/brocade/app.mxml?versionChecked=true
I reloaded Flash Player 8.5 and looked at the F2B1 chart
explorer http://weblogs.macromedia.com/flex_samples/charts_explorer/explorer.html
… but there aren’t a whole lot of style
examples. Any help would be appreciated,
