I wanna draw line chart

hi, i wanna draw line chart for some analysis of an image.
how can i do that?? plz help me in that, code would be more
better.thank u.

Yes, you can use the code for free and you can include it in your application for free. JFreeChart is and will always be free software.
What's not free is the JFreeChart Developer Guide (a 300 page Acrobat PDF document) and access to the JFreeChart Priority Support Forum. You have to pay for these, if you want them, the idea being that a well-funded project will progress faster than one that relies solely on volunteers.
I get some criticism for taking this "commercial" approach, but I am 100% certain that it has made JFreeChart a better product, so I don't care...

Can't seem to draw a chart (line chart) using dates rather than numbers

I'm trying to draw a Line Chart but rather using numbers i want to use dates for example: Switzerland 23/06/2008 - 23/08/2008. Can't seem to get it to work? it seems to all go wrong when I change the cell format to 'date'
Can anyone help?
Thanks
PS. I can do it easily in Excel

Hello
From my point of view, it's not surprising.
In XL, a date is a number to which a date format is applied. So, it may be charted.
Same thing with the good old AppleWorks.
With Numbers, a date is NOT a number, it IS a specific class of data.
The consequence is that it can't be charted directly.
Happily, we may easily convert a date into a number.
In column B the formula is
=A-$A$1
which calculates the numeric difference between stored dates and the date stored in A1.
So, we may chart the results.
I know that it's far from perfect but we have to live with the choices made by Numbers's designers.

Drawing TrendLines in Line Chart

Hi,
I am using a Line Chart in one of my projects.
I use a HTTPService to fetch XML Data to feed the chart.
<mx:HTTPService id="myServ" url="ChartData.xml" result="myResultHandler(event)"/>
I draw two trend lines over the chart based on the max & min values for a specified node in the XML data
<?xml version="1.0" encoding="utf-8"?>
<nodes>
    <node month="Jan-10">
       <expenses>20</expenses>
    </node>
    <node month="Feb-10">
       <expenses>30</expenses>
    </node>
    <node month="Mar-10">
        <expenses>80</expenses>
    </node>
    <node month="Mar-10">
        <expenses>20</expenses>
    </node>
</nodes>
I use the expense node in determining the max & min value for the chart.
I determine the max & min values & draw the lines in the result handler function:
If i use result Format = "e4x", I am able to iterate the data as XML List Collection, but when I get the data as ActionScript objects, I am not able to iterate the XML data.
public function drawLine(event:Event):void
     myChartCanvas.clear();
     myChartCanvas.lineStyle(2, 0x000000, 1);
     myChartCanvas.moveTo('Jan-10', 50);
     myChartCanvas.lineTo('Aug-10', 70);
How can i iterate the nodes in AS3 object format to find the max & min nodes & draw the trend lines ?

Cast the Objects. You know they are XML behind the scenes.

Please help me to draw a special line Chart!

Hi, I am programming to draw a line chart with X-axis as timepoint (for example, t1, t2, t3, t4, ...) and Y-axis as values (v1, v2, v3,v4,...) and have a line connecting all the (t, v) point. The issue I have encountered is that when a value (for example, v3) is missing at the timepont(t3), I still want the timepoint to show on X-axis but the connectiong line to stop at (t2, v2) and start again at (t4, v4). Is it possible to draw such a line chart? Is there any 3rd party supporting it? If so, may you please give me hints and help me out of this? Thanks alot.

How can I hide a segment of line in Line Chart.

Hi, All.
I have a problem in Crystal Report. I have a database field like this:
ID Creation Budget Actual
1 2007-1 30 45
2 2007-2 30 38
3 2007-3 30 42
4 2007-4 30 Null
5 2007-5 30 Null
12 2007-12 30 Null
This database storage the info about budget and actual
when the first month of each year, we input all the budget of the full year.
and we input actual data every month.
We hope our line chart can show a line about sum(budget) of the full year:
and another segment of line indicate the actual of the summary to current month. (eg. the data of 2007, this line will hide after 2007-4, but the budget will show all 2007 sum data)
| /budget(sum2007-12=360)
| /
| /
| /
|/-/act(sum2007-3=125)
What should I do? Please Help!!
Thanks.

Hi, Don.
Thank you
It seems that you are a SAP employee, You said "If you need quick help I suggest you purchase a case on line to get a dedicated Crystal Report Designer Engineer to help you ",
I wanna told you that It's not work. maybe Crystal Report is a good product, but it has the worst services in China. We've brought CR product, We've brought CR services. But we never get any services from their company.
Every time we post the information to their engineer, they never give us feedback. They donno how to do it either. They just sell product, but never know how to keep the customer's heart.
After SAP brought BO, I ever thought that SAP,the BEST management company in the world, would give the new life to BO. the services would be better. BUT, I was wrong..IT'S THE SAME..
I'm not aiming at one man or one company, But I really hope the services would be better. It HELPS.
Thank you anyway.
btw. I'm sorry for post in a wrong fourm.
Seraph.

Displaying regression line slope on line chart

Post Author: Derk_Niblick
CA Forum: Charts and Graphs
I've been having some difficulty building a chart. I'm trying to plot two different series onto a chart. A scatterchart is ideally what I am looking to use, but I cannot get the trendlines to work (I can't get the two different values into one series). I tried putting it into a line chart and while it's not working exactly how I would like it to, the trendlines work with it. However, I cannot calculate the slope of that line. I can view the formula (the linear trendline formula is in the standard y=mx+b type format), but i'm looking for the actual numeric slope value (y2-y1/x2-x1 for all you mathmatically inclinde folk). If I could get the program to give me two points on that line I can write a formula to calculate the actual slope of the line. Ultimately, I would like to chart the two different series (for example x = one value and y= another value giving me that precise location on the chart), draw a trendline through the points, and give a slope value. Can someone at least point me in the right direction.

JDEV 10G: how to display the value of the line chart using jChart in JSP

I have draw the line chart in JSP using the JChart and now I wan to display the value label in the line there..
but the value wasn't show..
anyone can help me..
thx..

Hi,
what I do understand, you want to display the value of each point in your Line Graph.
I guess you will be having BIGraph.xml file. In this file check the "Show Data Tips When Mouse is over bars" checkbox.
Lets try with this.

Change width of line in 2d line chart

I have created a 2d line chart, and Numbers draws blue lines connecting my datapoints. I would like to change the width of these connecting lines, but can't seem to find anywhere to do so. The only formatting option that seems to affect these lines at all is the "Connection Lines" setting, to set them straight or curved. Can you change the thickness of this line somewhere? Can you change the color?
Clicking on the line itself only selects the data points, like this:
There are no options here for styling the line's width or color.

As soon as I posted this, I discovered the solution. While selecting the data points, you need to select the "Style" tab under the Format sidebar, like so:
Then you can style the connecting lines however you like.

How to display a goal line in a Flash 2D Line Chart?

Hello,
I am using Apex 3.0.1 and have a Flash 2d Line Chart displaying a ratio that varies from 1.0 to 1.6 for every month for a year. I need to draw a goal line at 1.2 to show the goal for the ratio. Also, I have grid lines enabled for the y-axis.
Any pointers/tips on how to accomplish displaying this goal line would be really useful.
Thanks and Regards,
Dev

I'm having the same problem!
APEX is relatively new to me. CUSTOM XML for tweaking charts is even more recent. I tried to get a goal line to work in a line chart as you described but I have had no success. I really require a target/goal/reference line in a vertical bar chart but getting it to work in a line chart would be a welcome first step.
I have tried the following 2 samples of code without success:
<objects>
<line value='94' text='Target' text_position='right' color='0xFF3300' size='1' alpha='100'/>
</objects>
and
<objects>
<trend start_value='94' end_value='94' start_argument='' end_argument='' value='' color='0xFF3300' thickness='1' alpha='100'/>
</objects>
==> in the following blocks of the CUSTOM XML:
<chart .....</chart>
<chart..<line_chart .....</line_chart>..</chart>
<workspace> .. <chart_area .....</chart_area> ..</workspace>
<workspace> .. <y_axis .....</y_axis> ..</workspace>
<workspace> .. <grid> ..<values .....</values ..</grid> ..</workspace>
<workspace> .. <grid> .....</grid> ..</workspace>
Any idea where I am going wrong or what could be missing? Maybe I'm not putting the <objects> parameters in the correct place in the code?
