Thanks

Here is a perfect example of what I cannot decipher:
http://flex.amcharts.com/examples/chart_with_multiple_value_axes
^ You can even see the source code here. I believe they call it a "chart cursor".
Any idea what the mouse is doing, and how to get that line into a standard FLEX Linechart?
I see this a lot but have no idea what it's called....

Line chart's marker size is not changing

Hi,
I am using Crystal Reports 2008 and trying to change a Line Chart's marker size. The default size is 35, but every time I change it, it returns back to 35 again. Is there a bug in the application?
Thanks,
Al

Hello Al,
You need to turn of Auto Arrange in Chart Expert > Options > Layout
Changing the marker size conflicts with the Auto Arrange so it is not possible to change the Marker size with it enabled.

Hiding lines on a line chart (Display marker only)

I would like to only view Markers along with bars in combination chart. Need to make lines transparent or hidden (disable).
The X category axis is (different companies), so connecting line is not appropriate.
There are setting to hide other elements: Markers (Enable or Transparency), Column (Transparency).

Hi,
I don't think that is possible out-of-the-box. What you could do is the following:
1) Create a Bar chart
2) Create a XY chart (this will be your markers). Create a new series on the XY chart. Point the x-values to the x-axis labels on you bar chart. Point the y-values to the values you would like to display as markers.
3) Disable display of most of the elements of the XY chart, e.g. chart back ground, legend, vertical axis, gridlines etc.
4) Move the XY chart on top of you Bar chart
This will work, but might take a little fiddling :o)

Using CSS to change line chart tick mark font

I apologize if this has been covered elsewhere, but I can't find any reference to help with this.
I have create a dark-background theme for my CSS and have run into a bit of a blind spot with the CSS. My chart has a dark background, and I can find no way to change the color of the font on the tick marks. I have resorted for now to setting the individual axis objects setTickLabelFill for now, but it would be nice to be able to set this in CSS.
With this, I can change the font size of the axis labels and tick marks, but the font name and color are ignored for the tick marks:
.axis {
-fx-font: 14px "Palatino Linotype";
-fx-text-fill: white;
Thank you for your help.

That did work in 1.3, and I hoped it made it into 2.0, but that setting didn't help.
Setting the -fx-text-fill in -axix-tick-mark .label doesn't work either, or any variation I tried.

Line Chart

Hi There, I relatively new to Flex. Can anyone please help me
out in this Flex problem. Here is the problem.
I have 2 graphs which needs to be plotted on one Flex line
chart layout. I have date as x-Axis for these graphs. both the
graph starts with different date, example, graph 1 starts from
Nov7th and ends on Nov 22nd and second graph starts from Nov 27th
and ends on Dec 5th. when I plot these two graphs, the second graph
is overlapping onto first graph which is wrong, both shud be
plotted at different dates. How do i display both the graph
accurately?
Graph always starts from x axis base. Is it possible to make
the graph start from middle instead of start of x-Axis?
Pl advice. Thanks

I gave the outputs to know wheather the data is compatible for the chart. Because I have not done anything but just followed the wizard .
Navigation is..
Create Page-->Chart-->Line
and the rest are default except the query.
I even tried vertical bar which is also not working.
Note: I even tried after removing the ORDER BY clause.
This is the query which is working fine
select distinct sd_cnt_module_type, sd_metric_id, sd_weighted_violation
from cau_tr_si_detail t
union all
select distinct sd_cnt_module_type, sd_metric_id+2, sd_weighted_violation
from cau_tr_si_detail t
Problematic Query
select
prj.cau_ma_pr_name name,to_char(t.qi_date,'mon-yyyy') month,
round(sum(t.qi_finalindex)/count(1),2) as metrics
from cau_tr_qualityindex t,cau_ma_project prj
where
to_char(qi_date,'YYYY') = '2004'
and t.qi_project_id = 21
and
prj.cau_ma_pr_id = t.qi_project_id
group by t.qi_project_id,to_char(t.qi_date,'mon-yyyy'),prj.cau_ma_pr_name
order by t.qi_project_id,to_char(t.qi_date,'mon-yyyy')
Thanks In advance.

Line Chart glitch - grid lines thick at certain heights

The Flex Line Chart control does not display correctly at certain heights. The gridlines that are supposed to be 1px pin stripes are sometimes displayed up to 100px wide. This can be demonstrated with 1 line of code
<mx:LineChart height="33000" x="200" y="0" id="chart_1" width="100" ></mx:LineChart>
I also have another small app that uses a timer to demonstrate how as the height increases the gridlines increase from:
1px to 100px
then back to 1px
.... then as the chart's height increases another 7000px the 1px gridlines display correctly
then it repeats going back to thick, then thin etc... almost a pulsating effect

Are you able to acheive this.?
PCXML script is used for chart rendering, and with that I think you can't demark the Gridlines.
The following Xml file gives the definitions for the chart components including gridlines.
chartviewtemplates.xml
Which inturn refers to the following js for gridlines
i think you have to work on the Js here demark the grid lines by default
<Oracle_BIHome>\web\app\res\b_mozilla\views\chart
dlggridlineseditor.js
Before doing any changes take the backup.
Thanks,

How to dynamically add new line series to the line chart in flex?

i need to add line series dynamically..and each line series should have a different data provider...

A chart can have only 1 dataProvider which in my case is an ArrayCollection.
The chart will update every time the dataProvider changes if you use binding.
So you have to write a function that periodically populates the ArrayCollection with data from the server and the chart will update automatically.

Goal Line Chart in Flex

Hello All,
I'm creating a project that consists of flex chart componnents. However, client requires a goal line in the charts. I've googled allday on this and cant seem to find any samples. Is this even possible? If so, can you please lead me to the right direction.
Kinda like this example..but just have the goal line horizontal.
Jeff

Can you just take the min and max from the data source feeding your line chart, build a separate line chart with start and end corresponding to those two points and y-value corresponding to your goal, and add a second series to the chart? You may need to build a custom lineSegmentRenderer if you want a dashed line but a thin, low-alpha line may look fine.

Line chart and vertical line repeats according period

Hej,
I have line chart and horizontal axis displays many months, thus is possible to vertical line from horizontal axis be displayed after years period and be color diferent?? My example, start displays January 2007,......finish December2007->DISPLAY VERTICAL LINE as LONG TICK, start January2008....and so on... is possible to set such repeater for line chart...thank for response.

Hi 1234alex,
According to your description, you want to create a non-vertical target line in top of bar chart to show different target.
In Reporting Services, it’s impossible to create a non-vertical target line in top of bar chart. Because StripLines can only return a vertical target line even we put expression to make it dynamically . In this scenario, we can show the target line as values
and use switch() function to specify different values based on different category. Then we just need to change the chart type for that series only. However, it only support horizontal line chart type in Reporting Services, so we suggest you use column chart
instead of bar chart. Please refer to detail steps below:
1. On Chart Data region, set an expression looks like:
     =switch(Fields!month.value=”A”,”4”,
     Fields!month.value=”B”,”8”,
     Fields!month.value=”C”,”2”,
     Fields!month.value=”D”,”5”)
2. Right click expression in Chart Data region, choose Change Chart type, select a line chart.
3. Click Preview, the results look like:
If you have any question, please feel free to ask.
Best regards,
