MapViewer Html5 API. Error with Variable Pie Chart Style Model
Hello,
I have a serious problem related to Variable Pie Chart Style. MapViewer - Mapbuilder version: 11.1.1.7.3.
[ALERT] MAPVIEWER_9023:Cannot load style.
Source: OM.style.StyleStore.parseXMLStyle
OMS: oracle.mapviewer.share.stylex.VariablePieChartStyleModel cannot be cast to oracle.mapviewer.share.stylex.BucketStyleModel
In Mapbuilder, I have a geometry theme with rendering style, an advanced variable pie with variable range, style. This is the XML of advanced style:
<?xml version="1.0" ?>
<AdvancedStyle>
<VariablePieChartStyle startradius="5" increment="4">
<PieSlice name="T004_2009" color="#0033FF"/>
<PieSlice name="T004_2010" color="#FF0033"/>
<PieSlice name="T004_2011" color="#33FF00"/>
<Buckets>
<RangedBucket seq="0" label="0 - 20%" low="0" high="100000"/>
<RangedBucket seq="1" label="20 - 40%" low="100001" high="370000"/>
<RangedBucket seq="2" label="40 - 60%" low="370001" high="1000000"/>
<RangedBucket seq="3" label="60 - 80%" low="1000001" high="2500000"/>
<RangedBucket seq="4" label="80 - 100%" low="2500001" high="2.0E7"/>
</Buckets>
</VariablePieChartStyle>
</AdvancedStyle>
and this is the XML of the theme:
<?xml version="1.0" standalone="yes"?>
<styling_rules key_column="ID" caching="NONE">
<hidden_info>
<field column="INSTITUTION1" name="Port Name"/>
<field column="T004_2009_CHAR" name="2009"/>
<field column="T004_2010_CHAR" name="2010"/>
<field column="T004_2011_CHAR" name="2011"/>
<field column="T004_2012_CHAR" name="2012"/>
<field column="T004_2013_CHAR" name="2013"/>
<field column="T004_2014_CHAR" name="2014"/>
</hidden_info>
<rule column="PASSENGERS_2009,PASSENGERS_2010,PASSENGERS_2011">
<features style="V.T004_PASSENGERS_VPIE"> (NVL(PASSENGERS_2009, 0) !=0 AND NVL(PASSENGERS_2010,0) != 0 AND NVL(PASSENGERS_2011, 0) != 0) </features>
<label column="INSTITUTION1" style="T.CITY_NAME_H"> 1 </label>
</rule>
</styling_rules>
When I preview the theme in mapbuilder everything seems fine.
The problem arises, when I try to add a layer with this theme and style in my map in my APEX (version:4.2.6) application.
This is the javascript:
layer = new OM.layer.VectorLayer("layer1",
def:{
type:OM.layer.VectorLayer.TYPE_PREDEFINED,
dataSource:ds, theme:themename,
url: baseURL
map.addLayer(layer) ;
and this is the error I get:
[ALERT] MAPVIEWER_9023:Cannot load style.
Source: OM.style.StyleStore.parseXMLStyle
OMS: oracle.mapviewer.share.stylex.VariablePieChartStyleModel cannot be cast to oracle.mapviewer.share.stylex.BucketStyleModel
I' d appreciate any help.
Thanks in advance,
Vasso
Hi,
You're setting XML data in a JSON model, that's why the binding is incorrect.
Depending on what your MII transaction is returning, you need to either retrieve the JSON part in the XML, or use a XML Model.

MV 11gPr1 - variable pie chart issue
Hi,
Trying out advanced style - variable pie chart - we faced some issue - if data source contains bigger numbers (e.g. 100000,200000....) something causes that radius of all pies is the same. with smaller values (10,20...) the pie radius is variable.
thanks,
BranislavHi Joao,
here is the definition of that advanced style:
<?xml version="1.0" ?>
<AdvancedStyle>
<VariablePieChartStyle startradius="25" increment="15">
<PieSlice name="H" color="#005BBF"/>
<PieSlice name="O" color="#FC074F"/>
<PieSlice name="U" color="#00FF00"/>
<Buckets>
<RangedBucket seq="0" label="-Infinity - 4000" low="-Infinity" high="4000"/>
<RangedBucket seq="1" label="4000 - 6000" low="4000" high="6000"/>
<RangedBucket seq="2" label="6000 - 8000" low="6000" high="8000"/>
<RangedBucket seq="3" label="8000 - Infinity" low="8000" high="Infinity"/>
</Buckets>
</VariablePieChartStyle>
</AdvancedStyle>
thanks,

Issues with multilevel pie chart drill down with push button
I am new to Xcelsius. I am trying to build a multilevel pie chart drill down (one pie chart drilling down to another etc) and I am able to achieve that. Now I want to add a Back Button using Push Button so that I can go up. When I preview, the Push Button goes into two state and I have to double click to go back. Can anyone tell me what I am doing wrong. I am using the latest Xcelsius. [The source code is here|http://www.woofiles.com/dl-195360-3lTyVM8Z-piechartdrilldownwithpushbutton.xlf]
Thankyou.Hi Murali
This is exactly the same what i tried to do,
Drill down to 4 levels State -> City-> store etc with 4 pie charts and similar push button to close each level to
go back to previous chart, first run from 1 to 4 works fine, then after closing all the levels and when i am at the pie chart 1
if i click any pie slice it will jump to Pie chart 4 straight,
I tried tracking the issue, all i could find is some how the previous dynamic visibility values are back even after erasing
the data with the PUSH button (Destination cell insertion with blank or 0).
did you find a solution for this issue ?
Thanks

Error with variable substitution..

I am getting following error message for variable substitution

Would appriciate if you can correct the variable substitution...
RegardsTo reference the element that is in bold in the example, the following expression is used: payload:root,1,e1,1,e2,2
The parser searches for the first occurrence of the root element at the first level. It then searches for the first occurrence of e1 at the second level and for the second occurrence of e2 at the third level. The content of the last element (u201CExample Valueu201D) is set as the value for a specified variable.

Hi Gurus
I try to do a pie chart and a i´ve a problem .in the format Categories i use percent 0.00% for to see the value but i can´t see the name of the categories .it´s possible and how ?
thanks GursHi,
you can use $Category to display the category name in your format of a pie label. Combined with a line break your format string would look like <b>$Category$br$Percent0.00 "%"</b>.
Note that you must have IGS 7.00 patch 10 to use this feature. See also SAP notes <a href="http://service.sap.com/sap/support/notes/1076634">1076634</a> and <a href="http://service.sap.com/sap/support/notes/1064448">1064448</a> for more information.
Best regards

I tried to create 3D Pie Chart using the code below but it come back with no chart data available. I tested the select statement in sqlplus, it works. Is there something wrong with my select statement??
SELECT NULL LINK, 'Saturday' LABEL, DECODE(SUM(hours1),NULL,0,SUM(hours1)) VALUE
FROM Ewbs e,
Timesheet t
WHERE t.Company = 'A1000'
AND t.Entity_item = '504586'
AND t.Timesheet_date > NVL(TO_DATE('07-NOV-2008','DD-MON-YYYY'),TO_DATE('01-JAN-1900','DD-MON-YYYY'))
AND t.Timesheet_date <= TO_DATE(SYSDATE,'DD-MON-YYYY')
AND e.Ewbs_code = t.Ewbs_code
AND e.Hour_class = '13'
AND TO_CHAR(t.Timesheet_date,'YYYY') = TO_CHAR(SYSDATE,'YYYY')
UNION
SELECT NULL LINK, 'Sunday' LABEL, DECODE(SUM(hours2),NULL,0,SUM(hours2)) VALUE
FROM Ewbs e,
Timesheet t
WHERE t.Company = 'A1000'
AND t.Entity_item = '504586'
AND t.Timesheet_date > NVL(TO_DATE('07-NOV-2008','DD-MON-YYYY'),TO_DATE('01-JAN-1900','DD-MON-YYYY'))
AND t.Timesheet_date <= TO_DATE(SYSDATE,'DD-MON-YYYY')
AND e.Ewbs_code = t.Ewbs_code
AND e.Hour_class = '13'
AND TO_CHAR(t.Timesheet_date,'YYYY') = TO_CHAR(SYSDATE,'YYYY');Hello,
Can you create the same query you use for your chart as a report please?
Just to make sure you get actual data. One other thing, you can write DECODE(SUM(hours1),NULL,0,SUM(hours1)) as NVL(SUM(hours1),0)

Hi
I wrote a program that is supposed to call a method that returns 21 numbers with doubles from the user, then the program is supposed to call a method that displays the highest and lowest numbers entered as well as the average of the numbers. But... I get 2 errors that say cannot resolve symbol for lines 17 and 18 (which is this part number(arrays) and display(arrays) and another one that says cannot resolve symbols for line 40 int average = numbers.getAverage(); heres the program
import javax.swing.JOptionPane;
import java.util.*;
public class array
public static void main (String [] args)
number(arrays);
display(arrays);
int[] numbers = new int[21];
public static double number(int[] numbers)
for(int i = 0; i < numbers.length; i++)
numbers[i] = Integer.parseInt(JOptionPane.showInputDialog("Choose a number"));
public static double display(int[] numbers)
Arrays.sort(numbers);
System.out.println(numbers[0] + "is your lowest number");
System.out.println(numbers[21] + "is your highest number");
int average = numbers.getAverage();
System.exit(0);
}thanksyou loop through and assign the numbers in numbers to
a variable called sum then divide by numbers.length,
would that be how you do it?It might just be a case of sloppy wording, but as written, no, that's not quite what you'd want to do.
for (...) {
sum = numbers[ix];
} That's what your wording says to me. That may not be what you meant, but if it is, try it and see what happens. -
Errors with variable declarations
Hi,
Is it possible that when I declare a variable using the scriplet tags:
<% String test; %>
That it is not being declared properly and I cannot use it later on in the page?
<% test="Hello"; %>
I keep getting error messages and they seem to be centered around some of my variables that have been declared with scriptlet tags.
Thanks,
PreetiInstead of
<% String test; %>
use
<%! String test; %>
Then test will be accessible throughout instead of just the service method.
If the problem persists just post your code & specify the exact error.

hiwa -
I am new to Java and am having problems and I am in need of some help. I have written the code for my Mortgage Calculator but do not know how to get my chart to work. I found an example of the chart code in my text book but I am not sure if I wrote it wrong. When I run the MortCalc code it compiles but the Pie Chart code won't. I tried to run the chart code by itself but it prints out another calculator. My question is 1.) Is my chart code written wrong? and 2.) How do i enter it into my MortCalc code so that I get my chart?
**Below I have included the assignment(so you know what I am doing exactly) and below that the pie chart code just in case you have questions. Thanks for any advice you can give.
**If you need the rest of the code I can post it too. It was too long to post with the pie chart code.
Assignment:
Write the program in Java(w/ a GUI) and have it calculate and display the mortgage payment amount from user input of the amount of the mortgage adn the user's selection from a menu of availible mortgage loans:
--7 yrs @ 5.35%
--15 yrs @ 5.5%
--30 yrs @ 5.75%
Use an array for the mortgage data for the different loans. Read the interst rates to fill the array from a sequential file. Display the mortgage payment amount followed by the loan balance and interest paid for each payment over the term of the loan. Add graphics in the form of a chart.Allow the user to loop back and enter a new amount and make a new selection of quit. Please insert comments in the program to document the program.
CODE:
import java.awt.Color;
import java.awt.Graphics2D;
import java.awt.Rectangle;
//Class to hold a value for a slice
public class PieValue {
double value;
Color color;
public PieValue(double value, Color color) {
this.value = value;
this.color = color;
// slices is an array of values that represent the size of each slice.
public void drawPie(Graphics2D g, Rectangle area, PieValue[] slices) {
// Get total value of all slices
double total = 0.0D;
for (int i=0; i<slices.length; i++) {
total += slices.value;
// Draw each pie slice
double curValue = 0.0D;
int startAngle = 0;
for (int i=0; i<slices.length; i++) {
// Compute the start and stop angles
startAngle = (int)(curValue * 360 / total);
int arcAngle = (int)(slices[i].value * 360 / total);
// Ensure that rounding errors do not leave a gap between the first and last slice
if (i == slices.length-1) {
arcAngle = 360 - startAngle;
// Set the color and draw a filled arc
g.setColor(slices[i].color);
g.fillArc(area.x, area.y, area.width, area.height, startAngle, arcAngle);
curValue += slices[i].value;// Draw each pie slice
double curValue = 0.0D;
int startAngle = 0;
for (int i=0; i<slices.length; i+) {
// Compute the start and stop angles
startAngle = (int)(curValue 360 / total);
int arcAngle = (int)(slices.value * 360 / total);Look here and i think you will find some syntax errors.

Create Multiple Pie Charts with Drill Down capability(foreach in mainreport
Hello All,
i need to create a report with 4 pie charts, which should have drilldown capability. i tried to do that, and i can do only for two charts. i need for the rest 2 also.
Please help.

BO Design studio Chart Component issue ...!! | SCN
If Chart is bound to DS_1 and On Select event of chart is as below:

Hi Experts!!
I've a little problem with a Pie Chart, I want to present a Pie Chart with 3 values which are defined on the Data Series, when I deploy I get the message: "Expected exactly 1 data series in XXXXX chart. Extra data series ignored". I don't understand why, because if I try to do a Column Chart with the same information, it works Ok!
Can anybody help me please?.

Hello,
I found this example of pie chart, I tried to use several pie charts but the label square move in some chart. It shows the square moved down when it uses the vi.
I attached the example with 4 pie charts and sometimes it show the 4 sqaures and sometimes down one. Any way to fit it?.
I would like to see some example with 3d pie chart. Do you know any example?.
Thanks in advance!.

Error with cursor position on Chart
Hello
I'm getting an error with a simple Chart. I'm trying to show the chart position (using labels and a crosshair) and I'm getting an exception ONLY (it seems) when the program starts up with the cursor above the chart. If I move the cursor off to
the side or something I don't get the error.
Error: PositionToValue method cannot be called prior to calculating position of all chart area elements.
The error occurs in the MouseMove event handler.
private void crtPlotData_MouseMove(object sender, MouseEventArgs e)
Point mousePoint = new Point(e.X, e.Y);
crtPlotData.ChartAreas[0].CursorX.Interval = 0;
crtPlotData.ChartAreas[0].CursorY.Interval = 0;
crtPlotData.ChartAreas[0].CursorX.SetCursorPixelPosition(mousePoint, true);
crtPlotData.ChartAreas[0].CursorY.SetCursorPixelPosition(mousePoint, true);
lblXposition.Text = "Pixel X Position: " + crtPlotData.ChartAreas[0].AxisX.PixelPositionToValue(e.X).ToString();
lblYposition.Text = "Pixel Y Position: " + crtPlotData.ChartAreas[0].AxisY.PixelPositionToValue(e.Y).ToString();
HitTestResult result = crtPlotData.HitTest(e.X, e.Y);
if (result.PointIndex > -1 && result.ChartArea != null)
lblXvalue.Text = "X-Value: " + result.Series.Points[result.PointIndex].XValue.ToString();
lblYvalue.Text = "Y-Value: " + result.Series.Points[result.PointIndex].YValues[0].ToString();
}...etc.
The exception occurs at the "lblXposition.Text" statement.
For whatever reason if the cursor is above the chart at start up I get the error but I don't know how to prevent it long enough for "calculating position of all chart area elements".
Any help would be appreciated.
ThanksYet the event DOES work as long as the cursor is not within the chart boundaries at start up. ???
It happens to, but I would rely on the documentation. However, you can set a flag to true in the Paint event of the chart, and in the mouseMove handler, exit if the flag has not been set yet.

How to show pie chart in Oracle Map?
I created predefined theme with pie chart style using MapBuilder. When I requested map using XML map request, the pie chart are shown with background and base map behind. Unfortunately, I tried to use Oracle Maps JavaScript Client API and it showed only background with base map behind.
I’m using this code
themebasedfoi = new MVThemeBasedFOI('themebasedfoi1','geoadmin.pie_province ');
themebasedfoi.setBringToTopOnMouseOver(true);
mapview.addThemeBasedFOI(themebasedfoi);
geoadmin is my username and pie_province is my pie chart predefined theme
Sorry for my English
Many thanks

You can create chart by chart wizard in layout model in report 6i.
1. Create Query in data model
2. Go Layout model and right click
3. Select Chart Wizard then select Chart type
4. Select Axis (X axis column and Y axis column)
5. Choose your chart placement
