I am plotting an AreaSeries and a LineSeries on a AreaChart using Flex 3 in built chart components. I want to code a custom item renderer for LineSeries to be shown at the intersection points where LineSeries crosses AreaSeries.
View 1 RepliesThere is some information but I couldn't figure it out:How can I detect if a line intersects with a triangle ? And how can I detect the point of intersection in AS3 ?

View 1 RepliesWhen doing a gradient fill on an area chart, the gradient ratios are used only between the min and max of the chart. The area below the min is then filled with the last color in the gradient.
To make sure that it was using the ratios only between the min and max I inserted a zero (0) into the chart and the gradient expanded to the full height. I also checked the gradient values by creating a with the gradient fill.
How do i get the ratios to be effective through the entire fill not just between the min and max?
In a LineChart in Flex you can set a LineSeries to interpolateValues="true" what this does is connect missing values so you do not have gaps in your line. But what I would like is for it to insert 0's for the missing fields instead of drawing a direct line to fill the gap.
Is there a way to set it to do that?
the LineSeries is not dynamically added to my CartesianChart...What's wrong in this code:
private function chartComplete():void {
var ls:LineSeries = new LineSeries();
ls.styleName = 'timeline';
[code].....
I need to recalculate the max value of lineChart according to the visible lineseries. In the application I have the ability to make visible or not the lineseries of the graph and if I make not visible the lineseries with the actual top value I want to zoom in and change the top value of the graph.

how can i create mx:LineSeries dynamically depending upon array collection values. Now only 4 line series is there but some times i have to show more as per the array collection values change ex: if one more status HoldProject added to array collection?
I've created a Flex LineChart that shows high and low tide predictions over time. I'm using the LineSeries with form="curve", which produces a nice sinusoidal wave graph, representing water level over time. The X-axis represents time, and the Y-axis represents water level. The only data points I have to work with are high and low tide values, but I would like to figure out how to determine the y-values of arbitrary x-values along the line.[code]

You can easily set a stroke on a line series like this:
[Code]...
This will set alpha for the entire stroke to .8 But I want to be able to set a different alpha on the stoke for each plot based on something in the dataProvider. For example the yField in the lineSeries is "Apple" which is how it knows where to plot for the lineSeries. I want to be able to add something like alphaField which tells it what to set the stroke alpha for each plot.

I am implementing a LineChart in FLEX 4. I have the chart working well except I do not like the default colors and cannot use them, as they do not relate to my data very well. For instance, Orange is not a great default color for my data column "Outdoor temperature". I would rather override it and use a green color if possible.
When I explicitly specify the SolidColorStroke, like so, this breaks the LineChart Legend:
<mx:SolidColorStroke id = "s1" color="haloGreen" weight="2"/>
<mx:LineSeries yField="v1" form="curve" displayName="Indoor Temp" lineStroke="{s1}"/>
^ With this code, The LineChart Legend stops displaying the color for that specific LineSeries, and only displays in black.
How can I override the LineSeries stroke color and persist those colors to the Legend's display?
Is this a FLEX 4 bug? I noticed in FLEX 3 examples (even on Adobe's FLEX 3 Help website) you can override the stroke colors and it persists to the Chart Legend.
I have a LineChar, with one LineSeries, on which i am drawing values ( Y axis ), on specific time ( X axis ).The problem is that i don't wanna the points which is distanced on a specific distance in time ( let say 6 hours ) to be connected.Is there a way to make LineSeries with DateTimeAxis not connecting points distanted in specific time ?

I'm trying to improve upon the hitTest() function.I have a game in development that involves square robots, rectangular wall shapes, and line segment shots rotating and moving around. Without the rotation, hitTest works fine, but with rotation, problems arise.Walls at rotation 0,and square robots work fine. There is a small amount of funkyness with a rotated robot by a wall corner, but it's not very noticable.The big issue is collision of two rotated square robots.
I can create a function to get the line segments that make up each robot, and the check to see if any intersect. This will mean finding the location of eight points (using height and width and some trig to deal with rotation), finding the slope of eight lines, and then testing lines for intersection up to 16 times. This would be needed to find the intersection of each pair of robots. Those are worst case numbers, some colisions can be detected or ruled out before getting that far in the algorithm, but this check would need to be run every frame against all robots and walls and shots (shots could be a single line segment, though)Right now I'm talking about 8 robots max, maybe 6-20 walls, maybe 5-80 shots on screen @ 30 frames a second.
This is easy enough to create, but before I spend a day coding it all, I'm wondering if the computation requirements are going to make it prohibitive.(If so, I'll probably have to switch to circular robots).I feel like there should be a simple formula to find if two rectangles on a cartesian plane intersect, but I can't find one.
I need to calculate the intersection between two shapes in flash / action script. The problem is I can't access the shape's nodes and segments, and their coordinates, so there's no way I can calculate this. Do you know a way?
edit: further explanation: I imported irregular polygons from an EPS file to a movieclip with shapes in it.The mathematical solution to the problem is trivial, but to do that, I need to access by AS code to the coordinates of the nodes that make up the polygons, which I tried with no success. That is what I'm trying to accomplish.
edit2: dismiss this question. It's not possible. The workaround I'm applying is to save the polygons in SVG and parse them to get a list of nodes. then will feed that list to flash to calculate the intersection and areas on runtime.
I am currently working my way through a book on Game Programming in Actionscript 3, and have gotten to a formula required for collision detection on finding the intersection point of two vectors. Im not sure if the author uses vectors in the strictest definition, but the convention he uses is e.g for a vector V1 :
V1.a is the start point of the vector V1.b is the end point of the vector V1.ln is the vector perpendicular to V1 (its 'left normal') V1.vx is the difference between the x coordinate of V1.b and V1.a V1.vy similar to vx V1.dx is the same as vx , but for V1 scaled down to a unit vector (the direction vector) Now,in the example we have V1 which is the motion vector of the ship, and V2, which is the target vector (i.e the line the ship is going to collide with at some point)
In order to calculate at what point on V2 the ship will collide travelling along motion vector V1, the book gives the following code using the "perpendicular dot product" (Which i have not come across before) and creating a third vector V3 between the start point of V1 and the start point of V2 (V1.a and V2.a):

View 1 Repliesshow all datatips for a single lineseries in a Flex 3 linechart. This chart will have multiple lines and the functionality we're looking for is when a user hovers over a line, show all datatips associated with just that series.
showAllDataTips will not work in this case as it will display all datatips on the chart.
Using the ArcGIS Server Flex API, is there a way to convert mouse coordinates on the screen or the a map control to spatial coordinates in the map? It seems like there's functionality to convert map points to screen points, but a function for converting in the other direction seems weirdly absent.
View 2 RepliesFinding the intersection point of 2 line segments is easy enough.
But now I need to test wether a line with thickness intersects another (non-thick) line.
My idea is to actually perform 2 tests, one at the top and bottom of the thickness of the line. Does that make sense? Is there a better way to do it? I dont need the intersection point, just a boolean yes or no.

What am i doing wrong?
It's been a long time since I've done any work with actionscript, and alas I've forgotten nearly everything. I've tried to look for a tutorial that would explain basic animation with actionscript, but the one that I found on Kirupa was no longer there.
Basically I'd like to do this:On the stage I have a movieclip and I'd like the movieclip to move along the x-axis to a certain point and then back to the starting point again. The moving speed of the movieclip should also be adjustable.
I'm creating a game in flash for a university project, and learning actionscript and programming as I go. I'm very much still at a beginner level - at the moment al I have is some actionscript for drawing rectangles and moving them about the screen. This is what I'm having trouble with at the moment: I have a class called 'Creature', and I want instances of it to interact with each other. I want them to do something when they come within a certain distance of another instance. And I want them to be able to pick a random other instance to get the location of, in order to do something with that information.
What I think I need is: A function for telling the distance between two (x,y) points.
A way of referencing the nearest other instance of the class. And a way of randomly selecting from all of the instances of the class.

i have the follow issue :
I have a point which is setted at the border on a component, with changed transform point to the center of a component in order to match the component rotation.

how to get XY, after rotation ( changeing point.rotation property to specific degrees of rotaion )
I am using AS2 with Flash 8 Professional So, my problem is that I currently have a man in the middle of the screen, who shoots a line towards the mouse when I click. However, when I use hitTest to see if the line collides with another object, Flash recognizes the line as a large box if it is diagonal, so the hitTest isn't very accurate. The line only satys there for one frame, so I can't have the usual moving-bullet-style. I am either looking for a way to create an imaginary line with AS from the starting point to the mouse and beyond, and tell whether or not this line intersects with an object... or some other way that I haven't thought of to fix my problem. Keep in mind that the line rotates from a center point towards anywhere around it for 360 degrees.
