Animated line graph control?

Can anyone tell me what vendor provides an animated line
graph control like on farecast.com?
Please see the following site and click on the "Graph" tab:
farecast.com Line
Graph Control
Thanks!

i would try to achieve this with tweened mask.
first, draw the complete line on a layer above the JPG.
then on a layer just above the line, draw a rectangle that
covers it completely. convert it too a symbol (F8.) Right clicl on
the layer and set this layer to Mask.
Add enough frames to all layers for your desired animation
length.
On the Mask layer, add a key frame at the last frame.
On the Mask layer, on the first frame, scale the mask
rectangle Horizontally so that it only masks the first part of your
line.
Right click on the Mask layer and Create Motion tween. you
may have to adjust the Center poitn of your recangle mask (the
small white dot) to get it to scale up correctly.
you should see the rectangle scale out to cover the whole
line as the animation plays.
With both Mask and Line layers Locked, you should see the
mask reveal the line over time.

Animating a line graph

Dear javafx coders
I am a physics teacher in London and I am trying to learn JFX so that I can make animations for use in lessons. I don't know much about programming, but so far I have successfully managed to animate a circle which oscillates up and down (please see code below):

*var freq=0.001; //frequency of oscillation*

*yacc=-39.48*freq*(yold-100); //calculate acceleration
yvel=yvel+yacc; //update velocity
ynew=yold+yvel; //update position
MoveTo {x: 200+i*10 y: yold absolute: false} //graph from old position ...
LineTo {x: 200+(i+1)*10 y: ynew absolute: false} //..to new
yold=ynew;
Stage {
scene: Scene {
width: 400
height: 200
content: [
Circle {
centerX: 100;
centerY: bind ynew,
radius:20,
onMousePressed: function(e:MouseEvent) { time.play(); }
} The circle behaves as expected and oscillates up and down. However, I would also like to graph its motion beside it (using moveTo and lineTo, you can see these two lines above) but no lines at all appear on the screen. The idea is that on each new frame a portion of the line graph is added (i.e. from the old y position to the new y position, also adding on an equal x increment each time as we move along the time axis.
Any help on this would be really appreciated - I am very keen to move away from technologies such as Flash, but at the moment I am finding JFX a bit difficult.
Thank you

aheem...well! then how about this animation...I think I know what you are trying to do then. If I'm not mistaken, you are trying to do what the Ti-83 can do when graphing.

Oracle reports - Line graph

Hello,
I have a few issues with the line graphs (using oracle 10g dev suite R1 - 9.0.4).
1. Unable to make my y axis - a dotted line.
2. Since I couldn't make the y axis a dotted line, I made it a thin line. This thin line looks fine when I run it from the oracle reports builder. but when I genenerate to a PDF file, this thin line becomes thicker.
3. Thirdly, I want to place a dot or something wherever the value changes in the line graph. One option is to add the MarkerText visible="true" to the Graph settings xml file. but this puts the marker text to all the y axes.
I want it only for 1 y axis.
Cheers

Assuming you mean "series" and not "axis", you can control the style, width, and markers using the lineStyle, lineWidth, and markerShape attributes of the <Series> element (in the XML shown in the Graph Settings property) for the series (set of Y values) of interest.
For example, to use a thin, dotted line with circle markers on the first series, but leave the other series with their defaults, you might:
1. Make sure the markerDisplayed attribute of the <Graph> element is set to ="true". Otherwise, no markers will be displayed.
2. For the <Series> element with the id attribute equal to "0" (which identifies the first series), set the lineStyle attribute to "LS_DOTTED", the lineWidth attribute to "1" (in pixels), and the makerShape attribute to "MS_CIRCLE".
3. If needed, set the markerShape attribute of the other <Series> elements to "MS_NONE".
The Graph Settings property might look something like this:
<rw:graph id="CT_1" src="G_YOUR_GROUP" groups="X" dataValues="Y1,Y2">

</rw:graph>For more information, see the "Graph.dtd" file in your "%ORACLE_HOME%\jlib\bigraphbean.jar".
Hope this helps.

Different shapes for symbols in line graph

I can't figure out how to change the default square data points in a line graph. When I try to got to Object>Graph>Marker it is greyed out. When I click on a circle symbol and then try to go to Object>Graph>Design, it is greyed out. I am so frustrated trying to do the simplest things in this program. The online tutorials on how to make graphs do not seem to explain the simplest of tasks, only the difficult. Thanks for any help!

Do can do, see API..... You will need to create your own custom control by displaying a graphic with the rounded image. Search forum for displaying an image.

did you ever figure this out? I am trying to figure this out too, and it's not easy.

The ability to customize line attributes in a line graph (3 series)

Hello all,
I have a line graph page that plots three lines (series 1, series 2, series 3).
line 1 - upper boundary of a confidence interval
line 2 - actual estimate
line 3 - lower boundary of a confidence interval
Visualize three lines running along the axis. If the estimate line dips above the upper line or below the lower line, then that would indicate a problem for us to investigate.
It looks pretty but the end user wants the upper and lower boundaries to be 'dotted' lines instead of solid to help differentiate it from the estimate. Currently, I don't have any control over the line attributes using the built in wizard. Anybody know how I could customize the display so that lines 1 and 3 would be dotted while leaving line 2 as a solid line?
Thanks for any help.
James

James -
You are going to need to use Custom XML for this task
This link outlines (among other things) how create a process to create XML to replace the #DATA# in the Custom XML: Re: Chart with 2 Y Axis
In addition to this, the following link is useful in seeing how the page process can work: http://apex.oracle.com/pls/apex/f?p=36648:30:4466603909194692:::::&tz=-8:00
Next, you will need to create a new line style in your Custom XML (not the #DATA# tag portion, but the Custom XML of the chart) Here are a couple of references that may help: http://www.anychart.com/products/anychart/docs/xmlReference/index.html and http://www.anychart.com/products/anychart/docs/users-guide/index.html
Once you have defined a style in your custom XML, then your page process will need to make decisions about what style to use and apply the correct style to the appropriate lines.
I know this process is quite confusing at the beginning, however, with a little practice, it becomes much easier.

How do I make a line graph that shows temperature readings taken on specific dates?

I need to make a chart of my wife's temperatures taken via ovulation thermometer. All I need is a line graph that shows the temperatures on the y axis and the dates the measurements were taken on the x axis.
What is the easiest way to do this? Please explain in detail as I have almost no knowledge regarding Numbers. Thanks.

You can construct a Line graph or a Scatter graph to display this.
The two are similar, but require the data to be set up differently.
A Line graph is a Category graph.
Each 'date' is a text value that names a category. The categories are equally spaced along the category axis. Measurements taken on day 1, day 2 and day 4 would be equally spaced with respect to the category axis.
Each temperature reading is a numerical value, and is represented on the graph by the distance it is placed from (and usually above) the category axis.
A Scatter graph has two value axes.
Each Date is a Date and Time value. The position of these values depends on the value itself. Measurements taken on February 1, February 2 and February 4 wound not be equally spaced. Along the Date axis, the space between the second and third dates would be twice as wide as that between the first and second cates.
Each temperature reading is a numerical value, and is represented on the graph in the same manner as in the Line graph.
Here's an example of each, using the same data set.
For the Line graph (left), the Category labels (dates) are placed in a Header column, and the temperatures in a non-header column,
For the Scatter graph, both the dates and the temperatures are in non-header columns. The Chart Inspector was used to Connect the data points with straight line segments, and the weight of these lines (and size of the data point markers) was increased to more closely match the weights and sizes in the Line graph.
Data on the graphs is not intended to have any similarity to temperatures measured for your purposes.
The construct the line graph:
Set up the data and labels as described.
Select the cells containing the data (column B in my case).
Click the Chart button and choose the Line Chart.
To construct the scatter chart:
Set up the data as described.
Select the cells containing the date and temperature data (columns A and B for mine)
Click the Chart button, and select the Scatter Chart button (third from the bottom),
In the Chart inspector, click the Series button, then set the Connection Points menu to Straight. Change the Data Point size yo 15.
Click anywhere on the line to select it, then in the Stroke section of the Format bar, set the line weight to 4 points.
Click on the box containing the dates (under the chart), then click the ruler icon in the Inspector to show the metrics inspector. Use the Rotate control to set the angle for the dates to about 75°.
Click on the label for this axis (Dates) and drag it to a position below the date labels.

Barry

Graph control causes general protection fault when changing axis range (64bit)

Hello,
i wrote a 32bit application which i'm porting to 64bit now and stumbled across a problem with the graph control.
The Graph axsis are set to editable so that the user can change the axis range manually at runtime. The 32bit version has no problem here, but the 64bit version is crashing with a general protection fault at the source line with RunUserInterface().
Is there a compiler option/value or something i should be aware of when swithing to 64bit that should be set?
Or is this just a problem with the code of the control?
I tried it with LabWindows v13.0.2 (278) and v13.0.1, running under Windows 7 64bit.
Thanks.

Hello, danouj!
Thank you for reporting this issue to us!
However, information you provided is still unsufficient for us to determine the background of this bug.
Please also provide the following details, so that we can identify the issue and investigate whether a workaround for this problem exists:
From my understanding, when porting the application to 64-bit, you also performed some code changes to your CVI application. What are these code changes?
If you run the 64-bit version of your application without these code changes, does the application also crash?
What is the address of this crash?
It would also be very useful, if you can send us a copy of a minimal snapshot of your project application, in which the problem still occurs, for us to investigate the issue.
You can upload the sources at ftp://ftp.natinst.com/incoming

Graph control right-hand Y-axis tick marks look like negative signs

Hi,
The graph control right-hand Y-axis tick marks just to the left of the numeric values that make up the scale look like negative signs. It gets confusing for the user of the software.
The left Y-axis is OK because the little tick marks are to the right of the number.
Any ideas on how to improve this situation?
Thanks,
Kirk Mitchell
Project Engineer
Kollmorgen

Perry,
First of all thanks for looking at this.
The tick-marks controlled by the "Mark Origin" option are not the tick marks that are causing the problem.
The Mark Origin ticks are in the body of the graph along the x=0 and y=0 lines. They only show up if those lines are visible such as if you have a graph with an x axis range of -100 to +100 and a y axis range of the same.
The ticks I'm referring to are just to the left of the numeric values that label the right axis.
Below is a screenshot to illustrate:
Any other ideas?
Thanks,
Kirk

Is it possible to delete a plot with using mouse to select it on the graph control?

For example, when I use PlotLine to plot thousands of lines on the graph control, I want to delete some of them, but there is thousands of plotHandle generated.
How can I get the plotHandle of the specific line on the graph control with using mouse to select it?
If I record information of the lines, ex. the plotHandle and the coordinates, on a table or list, etc. , I have to compare the information of lines to get the plotHandle of the specific line.
Is there any user-friendly way to delete a plot by select it on the graph control?
Solved!
Go to Solution.

Sure! Look at the example located in \samples\userint\graphcursors for an example of how to accomplish this task.
Briefly:
The cursor must be in "Snap to point" mode
(To be confirmed) The graph must be in "Retain" data mode
You must have a callback for the graph control
You can use GetGraphCursorIndex to retrieve the plot handle
GetGrpahCursor retrieves values of cursor position in engineering units
Proud to use LW/CVI from 3.1 on.

ADF11g: dvt, line graph x-axis (o1 axis) display issue

Hi,
In our application we are generating line graphs for a set of data.
This graph is plotted in between 2 sets of numeric values. (one plotted on x-axis and other on y-axis).
For better accuracy of plotted graph we are using these numeric values upto 7 decimal places. (for example 8.1234567)
Now when graph is plotted, then on x-axis (that is o1- axis in case of Line Graph) the tick labels are showing upto 7 decimal places.
Is there any way so that I could control the display of these tick labels to 1 decimal place instead of 7 decimal places?
More Info:
++The tick labels for x and y axis are generated at runtime by some calculation logic.++
++If we set the tick labels for x axis to 1 decimal place instead of 7 decimal places when they are generated , then this will lead to build in accurate graphs.++
++So we can't control the decimal format of tick labels when they are generated. We need to control it when they are displayed.++
Please help...
Thanks and Regards
Manav Ratra

Hi Frank,
this is not working :( . It holds good for the case where one has to display markers (tick labels) on the lines of line graph and not the tick labels on the axis.
Moreover here i find out tag as *<dvt:x1Format>*
where as line graphs does not support x1axis they have o1axis .
In my case I need to control display of tick labels on the o1axis.

Line graph parent table child

i have a page where i have a line graph as parent and a table as its child. i want to have a master detail relationship through a view link of cardinality 1 to many.
when user selects appropriate points of line graph, the child table should refresh accordingly.
child table shows only children of firts record of line graph.
is there a problem with line graph being a parent. i could find examples which used bar / pie graph but not line graph. although i had checked the checkbox while creating graph.
i am using bind variables for both parent and child VO.
do i need to execute child VO query again to be able to display corresponding children for a parent on a line graph.

Hi,
when you create a line graph by dragging a collection (View Object) from the Data Controls panel to the page then, in the second dialog of the wizard, there is a check box "Set current row for master-detail". Check this check box and then create the table from the dependent view object. No bind variables required

Data Point Symbol in Line Graph - can you change the size?

I would like to change the Data Point Symbols in line graphs - if not the actual symbol it would be wonderful to be able to change the size of the symbols provided.
At present, if there is a lot of data in the graph, the symbols are too big and crowd one another.
I know that one can reduce the line size but that doesn't change the symbol size.
Help please.

If I understand your question, this from the Pages online help may give the answer:
To mark line, area, and scatter charts with data point symbols:
Select the entire chart. You can also select the chart series (the line or area shape) that you want to mark with data point symbols.
Click Inspector in the toolbar, and then click the Chart Inspector button.
Click Series (except for scatter charts).
Choose a symbol from the Data Point Symbol pop-up menu.
Choose one of the following options from the Symbol Fill pop-up menu:
To fill the symbol with the same color as its outline, choose Use Stroke Color.
To fill the symbol with a solid color, choose Color Fill, click the Fill color well, and pick a color.
To fill the symbol with a gradient, choose Gradient Fill and use the gradient controls to set the colors and change the angle of the gradient.
To fill the symbol with an image, choose Image Fill and select the image you want. You can also resize the image by choosing an option from the pop-up menu above the Choose button.
To fill the symbol with a tinted image, choose Tinted Image Fill and select the image you want. Click the color well to the right of the Choose button to change the tint color. You can also resize the image by choosing an option from the pop-up menu above the Choose button.
