Flex :: Dynamically Change Fusion Chart Value With Slider Event
Jun 4, 2010
I am having a set of slider for each bar in the graph. I have bindded all the sliders with their corresponding bars. When i change the value of slider the value in the ArrayCollection changes and i have also used
I am a scientist who knows molecular biology well but is a neophyte to Flex/ActionScript. I created a ColumnChart representing a probability histogram. I want to allow users to select a range of values on the X-axis via 2 sliders separate from the chart itself (one for the minimum value, one for the maximum.) By default the column bars are blue. But when the user selects a range, I would like to highlight that range in the chart a different color (eg. orange). How can this be done using ActionScript?
I am using code from the site, [URL] and I would like to make my slider smaller or bigger depending on the link. I'm guessing it can be done with action script, but have no idea how to do it. To view my file it's at: [URL] the FLA is at:[URL] Sadly, I need to squeeze one more link on the top menu and I am running out of room.
I am looking for an event which is fired (if any) after a chart is rendered (visible in UI) in Flash, we are using Flex SDK 3.0. We have to capture the screenshot after the chart is rendered, current implementation adds a huge delay in update_complete event callback, this is slowing down the whole job of generating images. I tried to use EXIT_FRAME event, but this doesn't seem to serve the purpose.
When executing dataprovider.refresh() for a chart component it redraws the chart. How do I determine when the chart is redrawn? I would like to take a png screen shot of the chart when it is fully drawn.
I am using FlashBuilder 4 and doing a simple application in flex. I am displaying a graph with 10 random values and based on the values I am trying to change the itemrenderer dynamically like CandlestickItemRenderer and BoxItemRenderer. Now my requirement was, if the values are > 10. I want to show my chart with CandlestickItemRenderer else i want to show the remaining spots as BoxItemRenderer. I am failing to do this. Either I am getting all the shapes as BoxItemRenderer or CandlestickItemRenderer. I am sending the code as a text file along with this.
I want to know when the data has been added to a chart so I can use localToData() to draw on the chart. If I do this immediately after setting the dataProvider the chart has not yet updated, so the the call to localToData will not return the correct values. Is there an event I can subscribe to so I know the chart has drawn the data in the dataProvider?
I have a several chart components that I have created in Flex. Basically I have set up a special UI that allows the user to select which of these charts they want to print. When they press the print button each of the selected charts is created dynamically then added to a container. Then I send this container off to FlexPrintJob.
i.e.
private function prePrint():void { var printSelection:Box = new Box();
[Code]....
I have seen some examples on the adobe site that add the container to the application but don't include it in the layout. This looks like the way to go.
I have created a line chart and another datagrid.based on dataitem clicked nthe chart should be changed. For example I have datagrid for stocks with 3 stocks GOOGL,Yahoo and ADBE .On clicking upon the GOOGL the google data should be loaded in to line chart.
how do i pass upperLimit="", dial value="" and maxValue="" values in colorRange dynamically from the flex side. i need these 3 values to plot on the angle gauge fusion chart
and my aim ise to create a Slider which can change starting and ending of the graphic, it is like what is showing in figure 6 in this website and here the MXML codes;
I'm trying to prevent a default chart item roll over highlight in a Spark column chart.If you look at any of the chart examples on this page , when you roll over any of the chart series items, they turn a darkened shade of their original colour. This is what I want to prevent.
So far I have had no luck with using the itemRollOverColor property, as this only allows you to set it to one specific colour for the whole chart (my app has several different coloured series on the chart at once). Also, trying to leverage the itemRollOver event (with preventDefault() etc) hasn't worked either.
I'm trying to make chart which is combination of bar and line chart using Flex Charting API . Here x axis would be common and y axis would be different. note that y axis got different range of value one is % and other is amount. Any one got idea how to make this chart. Here line chart would be staked on top of bar chart . The line chart and never over laid or drawn on top of bar chart.
I am displaying a combo box in something of a WYSIWYG preview. I want the user to be able to click on the combo box and see the options inside, but I don't want them to be able to change the value. I tried using preventDefault() on the change event but it doesn't work. I don't want to disable it because I do want the user to be able to "look inside" the dropdown.
So I'm trying to block the change, but can't. My next resort is to change the selected index back to what it was before the change, Is there any way to do this within the scope of a ListEvent.CHANGE event listener?
Current Workaround is to basically re-assign the controls selected item the same way I am defining the selected item when I originally build it (a default selection). So a user sees their change then it immediately changes back to the default selection.
I have been looking for a simple way to chart some data dynamically but to no avail. I have been using LineChart from Astra but I cannot change its data dynamically.
I think this very crude example should work, but it doesn't:
Code: // The flash simply consists of a LineChart called "chart" ... import com.yahoo.astra.fl.charts.*; import com.yahoo.astra.fl.charts.series.LineSeries;
-Place small boxes on my stage in the form of an org chart using only actionscript. These boxes will also need dynamically loaded titles vi XML. I will need the option to hide boxes that are not being used. (about 26 boxes)-I then want to be able to roll over each individual box and read a pop-up with dynamically loaded XML content.Can I do this utilizing only AS and XML?
If the size of canvas set in the MXML markup, some part of the components that go beyond the boundaries of canvas not displayed. If the canvas size to change dynamically(canvas.width, canvas.height), canvas boundaries are virtually absent. How to dynamically change the size of the Canvas?
I am in need of a strange solution. I have one requirement in which I am displaying two components in a VBox. But on click of the main container I need to maximize that and need to display the components in horizontal. I was just wondering whether I can change the VBox to HBox and viceversa dynamically using actionscript or some other way.
I am using a ContextMenu for an AdvancedDataGrid in my application. I could implement the normal context menu for the grid. Now, I am planning to make the context menu dynamic.For example, if I click on a particular cell, I need to see only the items related to that cell in the Context Menu. Is there any way we can do that?
I have a company's organisational chart in flash where it loads in each person's name dynamically for their department and when you click on it it brings up their CV information such as name, qualifications etc. This is loaded into a dynamic text box. I can test it locally with an xml file and then switch back to the online version.[code]...
Is there not an event that occurs only when there has been some sort of visual change to an object. So for example if it were a video or animated object it would be firing as often as EnterFrame. However, if it were some sort of input control just sitting there doing nothing visually, then the event wouldn't fire until the visual state changed as a result of some sort of user input for example.
What was the change in the textfield? I would want to compare the old text with the new text.the problem is, that I have multiple textAreas in a tab-editor, and all the textAreas are watched by one eventListener. I want to get a value calculated by the next formula[code]...
Can we change the width of the datagrid column dynamically by clicking on the border of the column in order to display the complete string which is too long to be displayed and needs to be scrolled ? If so, How ?
Also, how can we ensure that the column width changes dynamically based on the number of characters / length of string; since many a times the data is too long to be displayed. Can we set the column width to take the length of data into consideration before displaying onto the datagrid ?
It seems like there are various hacks out there to change the background colour of the row of a datagrid but all of them seem to happen at render time.See: http:[url]....I have a datagrid where I need to change row colours to red then back to normal frequently based on changes to the bound ArrayCollection. So I'm looking for a way to change the row colours dynamically.Obviously as the changes are happening frequently it would be nice if changing the background colour of the row wasn't an expensive process.
i have a simple datagrid having 2 columns named as image and place. where image column has mx.controls.Image itemRenderer and place is simple. my requirement is to change itemRenderer of image cell when it will be clicked. i means to say when user click on any image from image column than i want to show that image path in editable mode and when user edit that path then the selected cell will start displayed the updated image.
