flex - Draw a line on top of a column chart -


Apparently, it is not possible to have a chart with many independent horizontal axis

What do I get Trying to:

  • Display a chart, organized by any class
  • A line overlay (actually a single horizontal line) above it (some Type threshold to display)

I tried to do the following: 

  [bindable] public var Olm Detapradata: ArrayCollection = new ArrayCollection ([{ "category": "Cat 1", "value": 10}, { "class": "Cat 2", "value": 20}]); [BinDable] Public Worse Lineet Detroit: Arreculation = New Arrayization ([["X": 0, "Y": 10}, {"X": 1, "Y": 10}]);

... 

  & lt; Mx: column chart id = "columnChart" showDataTips = "true" columnWidthRatio = "0.5" paddingTop = "10" paddingLeft = "5" padding right = "5" width = "100%" height = "100%" & gt; & Lt; Mx: horizontal axis & gt; & Lt; Mx: category axis dataprider = "{columnsDataProvider}" categoryField = "range" /> & Lt; / Mx: horizontalAxis & gt; & Lt; Mx: series & gt; & Lt; Mx: column series id = "series 1" yField = "value" xField = "carrier" data provider = "{column data provider}" & gt; & Lt; Mx: horizontal axis & gt; & Lt; Mx: Class Axis ID = "Axis 1" CategoryFilled = "Category" /> & Lt; / Mx: horizontalAxis & gt; & Lt; / Mx: ColumnSeries & gt; & Lt; Mx: line series id = "series 2" yField = "y" xField = "X" dataprider = "{lineDataProvider}" & gt; & Lt; Mx: horizontal axis & gt; & Lt; Mx: LinearAxis id = "axis2" /> & Lt; / Mx: horizontalAxis & gt; & Lt; / Mx: LineSeries & gt; & Lt; / Mx: series & gt;

This is closest to what I want, except that the line does not start all vertically vertically (this is drawn between two columns of my bar chart).

Is it possible to define completely independent horizontal axis?

I also tried to draw directly on the canvas, but canvas. Lineto () method only works in "data" coordination; I'll need something that works in the "charts / canvas / complete / whatever" coordinates

any help on that?

Thanks PH

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
