Line chart with different "colors": Values not available are displayed as 0
Hello,
I defined a line chart with more than one lines (aka "colors" in the chart wizzard) - each line representing the (monthly) values of a year. x axis are the 12 months of the year; y axis are the values.
When one defines such a line chart in BIP client there is a choice between sum, average and count for the data values.
This is no problem for my template as there is only one value per month/year - so I used sum.
The problem: for the actual year there are no values for future months . But bip nevertheless shows 0 for this month/year... Can one prevent this?
Regards
Peter
Solved it finally - unavailable values must explicitly be passed to the report with nothing contained in the value tag.

Line chart with different length series?
Hello,
I would like to draw a line chart with three different series.
1. Previous year
2. Current year (until now)
3. Estimate (2 months)
I've got 12 values for the previous year, 4 values for the current year (January to April) and 2 estimated values for May and June.
When I define the three series, each is stretched over the whole width of the chart. How can I avoid that and force for instance the April values to be displayed above each other? Is it possible at all with this type of chart? (In Excel, it's quite easy...)
Thanks for any help!
SabineHi,
Youll have to write a query for your series 2 and 3 that has the same number of data points as your series 1 query, in your example that would be 12. Line series charts are always stretched over the full width by design. The months for which you have no data, would have a value of NULL. Please note that there is one issue, which has been fixed in 2.2, that causes the charting engine to only render dots instead of lines for series 2, 3, , if they have a NULL value at the last data point. So if I understand your requirements correctly, you should try this on our 2.2 hosted beta instance, and then upgrade to 2.2 when it comes out.

Creating a multi series line chart with different data providers
I have 3 data providers of the same structure i.e ArrayCollection of DataElement and want to use them to create a multiseries line chart. I do not have just 1 dataProvider that can be used but 3 different data providers of the same structure that i want to use each for different series.
[Bindable] private var orangeSales : ArrayCollection =
new ArrayCollection(
[ { sales: 101000, month: new Date( '01/01/2008' ) },
{ sales: 960000, month: new Date( '02/01/2008' ) },
{ sales: 475000, month: new Date( '03/01/2008' ) },
{ sales: 425000, month: new Date( '04/01/2008' ) }
[Bindable] private var appleSales : ArrayCollection =

{ sales: 140000, month: new Date( '02/01/2008' ) },
{ sales: 565000, month: new Date( '03/01/2008' ) },
{ sales: 255000, month: new Date( '04/01/2008' ) }

{ sales: 295000, month: new Date( '03/01/2008' ) },
{ sales: 574000, month: new Date( '04/01/2008' ) }
I want to create a line chart with orangeSales, appleSales and bananaSales as three different lines on the chart for different dates specified.

<mx:LineSeries displayName="BananaSales" yField="sales" xField="month" dataProvider="{bananaSales}"/>
</mx:series>
</mx:ColumnChart>
Please help!Sorry for the confusion. Actually I must be doing some thing wrong like using ColumnChart to display a line chart or something like that.
I have now realized that a multi series line chart can be built by having a different data provider for each of the LineSeries object.
So the code below would create a multi series line graph :
[Bindable] private var orangeSales : ArrayCollection =
new ArrayCollection(
[ { sales: 101000, month: new Date( '01/01/2008' ) },
{ sales: 960000, month: new Date( '02/01/2008' ) },
{ sales: 475000, month: new Date( '03/01/2008' ) },
{ sales: 425000, month: new Date( '04/01/2008' ) }
[Bindable] private var appleSales : ArrayCollection =
new ArrayCollection(
[ { sales: 991000, month: new Date( '01/01/2008' ) },
{ sales: 140000, month: new Date( '02/01/2008' ) },
{ sales: 565000, month: new Date( '03/01/2008' ) },
{ sales: 255000, month: new Date( '04/01/2008' ) }
[Bindable] private var bananaSales : ArrayCollection =
new ArrayCollection(
[ { sales: 891000, month: new Date( '01/01/2008' ) },
{ sales: 147560, month: new Date( '02/01/2008' ) },
{ sales: 295000, month: new Date( '03/01/2008' ) },
{ sales: 574000, month: new Date( '04/01/2008' ) }
I want to create a line chart with orangeSales, appleSales and bananaSales as three different lines on the chart for different dates specified.
<mx:ColumnChart showDataTips="true" >

On a chart, can we set portions of a chart with different colors
My application involves with fuel cell conditioning during which the V-I curve with go many cycles. I want to distinguish these cycles with different colors but don't know whether it's doable because I think if we set a color, it will set the whole line with the same color. Or if we can stop the line after one cycle and start the second cycle as a new line, then it will be a new color. Anyone can give some suggestion about how it can work? Thanks in advance.
GuangdeBy bundling multiple points together you can get different plots on a waveform graph. And +Inf plots nothing. I attached an example that plots a random number. When the boolean button is switched, it switches to the other plot line, thus another color. This was only done for 2 different colors, but the case structure and the cluster could be expanded for more than 2 colors.

Column Chart with different Color
Hi expert, i need help here, below is my code
foreach (DataRow row in dtTest.Rows)
int intIndex = 0;
string strVLegendName = row["Vehicle"].ToString();
if (chart1.Series.IndexOf(strVLegendName) != -1)
chart1.Series[intIndex].ChartType = SeriesChartType.Column;
chart1.Series[intIndex].BorderWidth = 2;
chart1.Series[intIndex].ShadowOffset = 5;
chart1.Series[intIndex].LabelForeColor = Color.Black;
chart1.Series[intIndex]["DrawingStyle"] = "Cylinder";
int intYValue = (int)row["Value"];
chart1.Series[intIndex].Points.AddXY(row["SeriesName"].ToString(), Convert.ToInt32(row["Value"].ToString()));
chart1.Series[intIndex].IsValueShownAsLabel = true;
chart1.ChartAreas[intIndex].AxisX.MajorGrid.Enabled = false;
chart1.ChartAreas[intIndex].AxisY.MajorGrid.Enabled = false;
else
chart1.Series.Add(strVLegendName);
chart1.Series[intIndex].ChartType = SeriesChartType.Column;
chart1.Series[intIndex].BorderWidth = 2;
chart1.Series[intIndex].ShadowOffset = 5;
chart1.Series[intIndex].LabelForeColor = Color.Black;
chart1.Series[intIndex].Color = Color.Yellow;
chart1.Series[intIndex]["DrawingStyle"] = "Cylinder";
int intYValue = (int)row["Value"];
chart1.Series[intIndex].Points.AddXY(row["SeriesName"].ToString(), Convert.ToInt32(row["Value"].ToString()));
chart1.Series[intIndex].IsValueShownAsLabel = true;
chart1.ChartAreas[intIndex].AxisX.MajorGrid.Enabled = false;
chart1.ChartAreas[intIndex].AxisY.MajorGrid.Enabled = false;
intIndex++;
the output is below
the problem is, instead of the only "Yellow" color in the chart, how can i change it to make it different color for example, Sedan = Yellow, SUV=Red, 4ton=Blue, 8ton=Purple...
Thanks in advanced...All what you need is to create a small function to pass category and retrurn color as below:
private Color GetColor(string category)
switch(category){
case "Sedan":
return Color.Yellow;
case "SUV":
return Color.Red;
case "4ton":
return Color.Blue;
case "8ton":
return Color.Purple;
default:
return Color.White;
and then in your code you call it as :
chart1.Series[intIndex].Color = GetColor(strVLegendName);
Also note that you can create color from name as below, so if you saving colors in your DB/DT you can just pass as below and it will return color for you.
Color.FromName("Blue");
Which you will be able to pass in your code as below:
chart1.Series[intIndex].Color = Color.FromName(row["DBColor"].ToString());

APEX multi series line chart with different markers for each series
I am using APEX 4.0 and trying to create a multi-series line chart that will have a different for each series.
Does anyone know how to accomplish this?
Edited by: user4635837 on Apr 19, 2011 7:22 AMHello -
It is possible to do.
Another user in this forum has written some code snippets to assist in creating your own custom XML for charting. That reference can be found http://apex.oracle.com/pls/apex/f?p=36648:30:418355095936797::NO:::
Look this over and it should get you moving in the right direction.
What you are trying to do isn't terribly difficult. In fact, I did it fairly easily as can be seen http://apex.oracle.com/pls/otn/f?p=28155:4:362637005964920:::::
First, create a Hidden page item.
Next, create a process that runs before regions
That process will create the XML for your line chart and store it in the hidden page item. Use the above references for assistance in setting up the PL/SQL in the process
Then, create your custom XML for your chart. Replace the #DATA# tag in the custom XML with your hidden page item.
It is a bit daunting at first, but once you get the hang of it, it really isn't that bad.

Plot empty point in line chart with previous non empty value
Hello,
I have a problem to plot series data in SSRS line chart, with the empty point, I don't want use average and zero provided by the report builder, I want use the last non empty data to fill the empty point, tried to use expression =Previous(Field!Value), no
luck, any one have some good idea?
P.S. do not want to use query to fill the null with previous non null value, just from the performance point view. at last , the chart should have some line as square wave with different height, if I use average for empty point, it shows slop wave line which
is not reflect the real production.
Thanks
RichardHi Richard,
In Reporting Services, if the chart type is a linear chart type (bar, column, scatter, line, area, range), null values are shown on the chart as empty spaces or gaps between data points in a series. By default, empty points are calculated by taking the average
of the previous and next data points that are not null.
If we want to use previous value to replace the empty value, please refer to the following steps:
Right-click the field which displayed in Y axis (Height) to open the Series Properties.
In the Value field to modify the expression to look like this:
=iif(isnothing(Sum(Fields!Height.Value)),previous(sum(Fields!Height.Value)),sum(Fields!Height.Value))
The following screenshot is for your reference:
If there are any other questions, please feel free to ask.
Thanks,

Not able to color different rows with different colors in a column of table
Hi,
I am trying to to display different rows with different colors in a column of the table based on some decode condition.
I have gone through the following threads :
Can we colour the rows in the column of a table
Changing Color of a value in a column
This is what i have done :
1.Added the following code to custom.xss(changed the name to Custom.xss as suggested in one of the above threads) --- in path ---- jdev\myhtml\OA_HTML\cabo\styles
<style selector=".1">
<includeStyle name="DefaultFontFamily"/>
<property name="font-size">11pt</property>
<property name="font-weight">Bolder</property>
<property name="color">#008000</property>
<property name="text-indent">3px</property>
</style>
<style selector=".2">
<includeStyle name="DefaultFontFamily"/>
<property name="font-size">11pt</property>
<property name="font-weight">Bolder</property>
<property name="color">#FFFF00</property>
<property name="text-indent">3px</property>
</style>
2. Sql query of the VO is :
select comments,role ,decode(role,'REQUESTER','1','2') Colorattr from xxat_sars_action_history where request_id = :1 and event_name = :2 and action_code <> 'PENDING'
order by sequence_num desc
3. Coded the following in the process request of the controller:
OATableBean table = (OATableBean)webBean.findIndexedChildRecursive("CommentsTB");
OAMessageStyledTextBean roleBN = (OAMessageStyledTextBean)webBean.findIndexedChildRecursive("role");
OADataBoundValueViewObject cssjob = new OADataBoundValueViewObject(roleBN,"Colorattr");
roleBN.setAttributeValue(oracle.cabo.ui.UIConstants.STYLE_CLASS_ATTR, cssjob);
where 1 and 2 form the colors ( i have even tried with 'Red' and 'Yellow'...as it was not working replaced with 1 and 2)
4.The query returns data fine with corresponding 1 and 2 values.
But different colors are not getting reflecting on to the UI.
I am testing this on my local jdev.
Please do let me know if i am missing something.
Thanks ,
Sushma.Any Clues please.....

Line chart with more than 15 data series - color problem
Hi all,
I've built a line chart with 32 data series (user can control, which of them are displayed at a time). For series 16 to 32 I did manipulate the URL in the browser directly, because Application Express does only display parametrs for up to 15 series. This works fine so far except of displaying the colors. For each sieries I defined a different color. 29 of my 32 series are displayed in the desired color. But series 29, 31 and 32 are displayed in a default-color (#0099CC). It seems that this is a SVG-problem. In the SVG-source I find the wrong color. When I export my application, I see the right color.
Thanks for help,
ChrisHello,
Which version of APEX are you using?
Go to your Flash Chart attributes - get into your series (click the icon) in the section of Series Query you'll find the maximum rows.

Dimitri

Line chart with 2 different y axis
hi,
i have a question on line chart in apex. i'm using apex 4.2. is it possible to generate a line chart with 2 different y axis? here's a sample data to illustrates what i'd like the chart to look like.
date price percent
1/1 1 100
1/2 2 90
1/3 3 80
1/4 4 70
the x-axis will be the date column. the left y-axis would be the price column. and the right y-axis would be the percent column.
i know i can plot multiple lines in a chart thru different series. but they're based on the same x and y axis range. thanks
jimYou beat me to it.
One of the problems I'm having is that the begining and ending point(s) coincide. So, instead of two completely separate lines, I have an area bounded by the series 1 line on top and the series 2 line on the bottom. Since the points overlay, the values of those points also display one on top of the other. I'll have to see if there is a way to separate the series. I've had 3 separate series before, but never with two y-axis.

Cracked iPhone 6 screen and screen is all white with different colors going down it. What do I do???
Take it in for repair or exchange. Be prepared to write a pretty big check unless you bought AppleCare+.
If your iPod Touch, iPhone, or iPad is Broken
Apple does not fix iDevices. Instead, they exchange yours for a refurbished or new replacement depending upon the age of your device and refurbished inventories. On rare occasions when there are no longer refurbished units for your older model, they may replace it with the next newer model.
ATTN: Beginning July 2013 Apple Stores are now equipped to do screen repairs/replacements in-house on iPhone 5 and 5C. In some cases while you wait. According to Apple this is the beginning of equipping Apple Stores with the resources needed to do most repairs for iPhones, iPads, and iPod Touches that would not require major replacements. Later in the year the services may be extended as Apple Stores become equipped and staffed with the proper repair expertise. So, if you need a screen repaired or a broken screen replaced or have your stuck Home button fixed, call your local Apple Store to see if they are now doing these in-house.
You may take your device to an Apple retailer for help or you may call Customer Service and arrange to send your device to Apple:
Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information.
To contact product and tech support: Contacting Apple for support and service - this includes international calling numbers.
You will find respective repair costs in the appropriate link:
iPod Service Support and Costs
iPhone Service Support and Costs
iPad Service Support and Costs
There are third-party firms that do repairs on iDevices, and there are places where you can order parts to DIY if you feel up to the task:
1. iResq or Google for others.
2. Buy and replace screen yourself: iFixit -
IPad 1 display with different color line
My iPad display shows with different colors here & there. Is that defect? Some web page is ok. But most of time you can see that.
Mountpa-
Your iPad may be defective, but is probably out of warranty. An Apple Store may exchange it for a flat rate. Look for an iPad repair center for a less expensive repair. You can find an Apple Authorized Repair Center at <Apple Authorized Repair Centers>, but non-Apple repair centers may be less expensive still.
First check to see if your color happens to be part of your iPad's wallpaper. Go to Settings-Brightness & Wallpaper to see how it is currently set.
One thing you can try is to reset (reboot) your iPad. Hold both the Home and Sleep buttons for several seconds until the Apple logo appears. Ignore the "Slide to power off" arrow. The iPad will restart after a couple of minutes. Resetting this way will not hurt anything, and sometimes clears up mysterious problems.

front dia.JPG 122 KBHi all! This is my first post
My name is Francesco and I'm programming a keithley for measure some FET
using labview 8.6. I plot my output data on a XY graph but I have several curves,
one for each value of Vgs. Looking in your forum I've found the code
MultiplePlots.vi (21 kb) posted by Darin.K about a month ago that use Multiple
plots and it is perfect for my goal because with this I can plot every curve with a
different color. The only problem is that I like to plot my data in real time.
The code, however, use a Loop with N=50, accumulates the values on the edge
and plot at the end of the Loop the entire line.
My question is if someone can explain me how to modify the code to plot the line
point by point, so in real time and not at the end o the loop because I need to see
the current values during the measurement and not only at the end.
I think that I need to move the XYgraph inside the loop. I try but without lucky.
Can anyone help me?
thanks and sorry for my very bad english.

Multiple Line Charts with Column Chart
I want to show two line charts with a column chart. Everything goes on the screen fine, except the two line charts origination point always starts at the same point despite the numbers being different. For example, the ls1 might read 280, 190, 180 and the ls2 is 175, 188, 177 but both origination points start at 280. The other two datapoints should also be close together but they have a substantial gap of about 50 between them. Obviosuly I want to have two separate lines. I have also tried moving the line series below the first lines series with no success.
