Horizontal Axis X doesn't cross at $0

I have a column chart with negative values. I need to have a clean design of the dashboard and i took off all horizontal gridlines
In Excel charts you have an option to show your X Axis at 0 value on the chart, but it looks like we don't have this option in dashboard charts.
Does anyone knows any creative solution how to show the Z Axis at 0 value???
Thank you.

Hi Alex,
Try changing your scale in the 'Behavior > Scale' tab to "Manual" scaling. You will need 2 formulas for the min/max.
A = rounddown(min([range of all values]),-4)
B = roundup(max([range of all values]),-4)
These will give you your lowest and highest values being plotted, and round down or up to the nearest 10,000.
In the Divisions section below that, bind "Size of Division" to the following formula:
(B - A) / 4
Then in 'Appearance > Axis' tab change show only major grid lines, and change them to be the same color/size as your horizontal axis. You should get something similar to the attached result. Slightly different than what you're looking for, but the closest you'll get without custom graphics/layering multiple charts.

Number: chart: set the horizontal axis (x-axis) crosses at

When creating a chart in number, how can I set the horizontal axis (x-axis) crosses the y-axis at the point I want it to be? In other words, when I create a chart, the x-axis is automatically set to be at the bottom, but what if I don't want it always to be at the bottom?

If you want the axis line somewhere else, you can draw a line on the chart using the graphics tools, having deselected the option for an automatic Axis line.

I want the minimum of the horizontal axis to be the first day of the month.

I have a situation where I want the minimum of the horizontal
axis(with date time axis) to be the first day of the month. I
attempt it like so:
var max:Date = new Date();//current date is our max from
which we will calculate the min
var min:Date = new Date(max.fullYear,max.month,1);
dateTimeAxis.minimum = min;
However this first date on this axis is the last day of the
previous month for example 31 August instead of 1 September. Any
ideas how to fix?

Nikos, the only thing I can think of (off hand) is that it's
defaulting to "zero" hour on that date, if you tried:
var min:Date = new Date(max.fullYear,max.month,1,13);
Would that make it work? That would set the date to 1pm.
Have you considered defining the axis with the data you are
binding to?
Cheers,
David

OBIEE 11G: Can I set limit on number of ticks only on horizontal axis and zoom in if I want to?

Hello
Is there a way I can restrict the total number of ticks on horizontal axis only? Say I want to set it to show only 24 ticks on horizontal axis. I am putting date and hour on the horizontal axis, if I take 3 dates of data, I will have 3X24 = 72 ticks on the chart, but I want the chart to show only 24 ticks. So it's pretty much ticks for 3 hours on the horizontal chart in this case.
Can this be done?
Second, if the first can be done, then can I then zoom in to any ticks on the horizontal axis, and it would show be the break down of this ticks, which is made up with 3 hour's performance separately?
Thanks

The zooming feature was ok, but what if I want to zoom in on just a specific area between the ticks when only 1 click?
Any thoughts?

Feedback on impementing second horizontal axis using Flex 2.0.1

I am attempting to use the concept of a second horizontal
axis using Flex 2.0. It is not clear to me if it is supported by
the Flex 2.0.1 sdk although livedocs does provide an example using
secondVerticalAxis. A snippet of my code is attached with this
message. At runtime, the second series does not display. Any
feedback about usage of the component would be greatly appreciated.
Thanks.

>>That data base is fine for a development environment.
Thanks edbrendel.
So, since I am able to run Apache 2.2 as I want to, would I
be better of to use MySQL 5 or MS SQL Express if I want it to be
largely development, but also for my own stuff (my galleries etc.)
actually running pages served to the web?
I know of the technotes, a couple of them (incl. the MySQL
note on installing V. 5 as a datasource and all that), but never
saw that one...so thanks very much. I've manually added the Apache
2.2 file line in httpd.conf and added the file in the config area,
which always worked in the past with XP Pro and XP64...hope it does
with 2003 I had 2003 server when I first started playing, it was a
nightmare, I hope now that I've bought everything I can wrap my
head around it!). I just make sure I don't try to configure CF
until after manually adding the files, and changing the Apache
config file and restarting. Then I go into the administrator for
the first time.

PlotXY manual X Axis Scaling doesn't rescale Y-Axis auto-scaling

I'm using PlotXY(..) to display data on a graph.
I use SetAxisScalingMode(...) to set set VAL_LEFT_YAXIS to VAL_AUTOSCALE.
I use SetAxisScalingMode(...) to set set VAL_TOP_XAXIS scaling to VAL_MANUAL.
I make various calls to SetAxisScalingMode(...) which change the min & max values for the X-Axis.
Everything thing seems to display correctly except that changing min & max values using manual scaling on the x-axis does not seem to change the range of data used to auto-scale the y-axis.
For example say you have a peak in your data that you want to exclude so the auto-scaling on the y-axis will zoom in.
So you change the max, min manual x-axis scaling to leave out the peak but scaling but the y-axis scaling doesn't change.
Is this the way it should work?
Ideas for a work around?
Thanks,
Kirk

Hi Kirk,
As you've noticed, the autoscaling of an axis in the graph is based on the entire data of each plot, not just on the portion of the plot that is within the range of the other axis.
If you use only integer limits for the min and max of the x axis, if you plot only 1D arrays, and if you don't mind re-plotting every time that you want to manually change the x-axis, there's a possible workaround, consisting of replacing PlotY with PlotWaveform, so that you can offset the data to plot.
I've adapted the code that you attached earlier to illustrate this:
int xmin = 40;
int xmax = 90;
SetAxisScalingMode(handle, PANEL_GRAPH, VAL_BOTTOM_XAXIS, VAL_MANUAL, (double)xmin, (double)xmax);
PlotWaveform (handle, PANEL_GRAPH, datapoints + xmin, xmax - xmin, VAL_DOUBLE, 1.0, 0.0, xmin, 1.0,
style, VAL_EMPTY_SQUARE, VAL_SOLID, 1, color);

Labels are not clearly visible on Horizontal Axis

I want to display a full timestamp on the horizontal axis of a LineSeries. But the labels are not clearly visible. The below is the screenshot.
I have already tried using LabelRenderer and set a larger font size and also tried increasing the width of the label itself. But, it didnt work. It seems there is some container for the lable which has fixed width. Does anyone know how to increase this width and make the text clearly visible.
Thanks

Hi Mohd Fayaz,
Have you tried setting the larger fontSize on LineChart.
<mx:LineChart fontSize="18" />

Horizontal axis Labels in tabular style

I have a weird requirement. I want to draw the horizontal axis of a column chart in a tabular style, like a table with one row. each label will become one cell. I am trying to tweek it out, since I can see labelRenderer of AxisRenderer is the only way for that. I had a small lead, when I used opaquebackground to give the backgound color. But since am using label renderer for formatting the labels, the opage background is painting in too much thickness. please give any input if anyone have any other lead.

Hi Stewart,
I could not try this yet, but how about 'Enabling the Contains HTML Markup' for the columns for Heading and including a '</br>' tag at the end of the name.
Ex: Column - >Properties -> column Format -> Column Heading -> Enable Contains HTML Markup -> Column Heading's suffix =less than symbol /br greater than symbol (Oracle forums is even break the line too!! ;) So included the text)
Hope this helps.
Thank you,

Horizontal Axis labels display

I have a graph with the a daily value for a whole year which
means I have 365 values on one graph the lineseries are readable
but the fact to have 365 labels on the X-axis makes it not
readable. Does anybody knows how to display only one label over ten
of the horizontal axis.
Thank you for your help.

Anyone help me in this ???
some time i need to hide them also. how to do ?

Break for Horizontal Axis Labels in OBIEE 11g Bar Chart

Hi all,
I have a vertical bar chart created in OBIEE 11g. The horizontal axis (x-axis) is a compound of Scenario, Year, and Month. The chart width is already long enough so it cannot be made any longer.
The chart looks like this (the label of horizontal axis is staggered):
___llllllllllllll_________llllllllllllll_________llllllllllllll_________llllllllllllll
___llllllllllllll_________llllllllllllll_________llllllllllllll_________llllllllllllll
___llllllllllllll_________llllllllllllll_________llllllllllllll_________llllllllllllll
___llllllllllllll_________llllllllllllll_________llllllllllllll_________llllllllllllll
Actual Feb 2012____________Actual Apr 2012
___________Actual Mar 2012_____________Actual May 2012
How can I force the labels for the horizontal axis to be broken into 2 lines (or even 3 lines), so that it will look like this:
___llllllllllllll_________llllllllllllll_________llllllllllllll_________llllllllllllll
___llllllllllllll_________llllllllllllll_________llllllllllllll_________llllllllllllll
___llllllllllllll_________llllllllllllll_________llllllllllllll_________llllllllllllll
___llllllllllllll_________llllllllllllll_________llllllllllllll_________llllllllllllll
___Actual________Actual________Actual________Actual
__Feb 2012_____Mar 2012_____Apr 2012______May 2012
Any advice? Thanks a lot!

Chart horizontal axis show whole year

Hi All,
How to display whole year month as horizontal axis even if no data? for example, currently I have data for FY13 up to Jan 13, no data for Feb 13, Mar 13, Apr 13, May 13 and Jun 13 yet, in the chart it will automatically showing horizontal axis from July 2012 to Jan 2013, but I want to show horizontal axis from July 2012 to June 2013, if not yet data, line stops.
Thank you,
Ling

Hi,
Apart from the option mentioned above, you can also create an right outer join in the BMM layer of the RPD.
This is only recommended if the data expected by you is the same in all the reports using this combination of the tables.
Thanks,

Line graph, How do graph month only on Horizontal axis?

I'm trying to graph year trends by month on the horizontal axis. However, it keeps breaking up the months by adding the year, so I have three separate line trends. How do I fix this?

Hi,
You should move to the production version of JDeveloper 11g that was just released:
http://www.oracle.com/technology/products/jdev/index.html
However I have a answers for your questions:
1. Setting time tick labels to hours: This should work by setting continuousTimeAxisInterval="CTAI_HOUR" on the advanced graph tag.
Here's the tagdoc for that attribute.
continuousTimeAxisInterval
Specifies the interval along a continuous time axis only if you want to override the value that the graph calculates automatically. Valid values are as follows:
* CTAI_AUTOMATIC - (Default) Graph calculates the interval automatically.
* CTAI_YEAR - Sets the interval to years.
* CTAI_MONTH - Sets the interval to months.
* CTAI_DAY - Sets the interval to days.
* CTAI_HOUR - Sets the interval to hours.
* CTAI_MINUTE - Sets the interval to minutes.
* CTAI_SECOND - Sets the interval to seconds.
2. Vertical gridlines can be set by using the o1Axis tag and setting the tickStyle. This should change all o1Axis ticks to gridlines. For different lineStyles, you can also use the lineStyle attribute.
<dvt:graph>
<dvt:o1MajorTick tickStyle="GS_GRID"/>
</dvt:graph>
Hope this helps

Crosstab missing horizontal axis fields

I have a crosstab discoverer report with the following structure:
====================================================
.............|Y | Y | Y |
X1 X2 X3 |Z | Z | Z |
X1 X2 X3 |Z | Z | Z |
X1 X2 X3 |Z | Z | Z |
X1 X2 X3 |Z | Z | Z |
Y = verticle axis item
X1, X2, X3 = horizontal axis item
Z = datapoint item
Discoverer Desktop Edition v4.1.48.06.00
====================================================
For a particular row, X2 and X3 are always blank, but I know that they actually have a value.
If I go into edit sheet and change X2 and X3 to datapoint items and refresh the sheet, then I can see their values. If I then go into edit sheet and put X2 and X3 back to horizontal axis items, then their values appear. However the next time I open the sheet I have to do the same.
Any ideas??? Please note that upgrading to a newer version of Discoverer is not an option.
Thanks

Hi Gareth
That's actually the way drilling works behind the scenes. Think of how you would do it yourself. If you wanted to drill up, essentially collapsing, you would remove the item(s) that were causing the details to be displayed and add a condition to only display by the items you want.
Even though you didn't ask Discoverer to do it, in effect you did when you told it to collapse. The answer is - don't drill or collapse and then save. This saves SQL which you probably will not want.
Of course I appreciate that this is not what you wanted to hear but please don't shoot the messenger. I don't work for Oracle you see, I just know how Discoverer works.
Best wishes

The actual age(months) values is up to 240.5 months. So this
xml is kind of too long to post. ;)
Anyways, the goal is to present this data into a line chart
with the elements:

-the values of P5,P10,P25,P50,P75,P85,P90,P95 in vertical
axis.
The values are plotted so well in the chart and so is the
vertical axis. The problem is in displaying labels in the
horizontal axis. Primarily, I made use of CategoryAxis but the
labels are not displaying at all. And then i utilized LinearAxis
and created a labelFunction renderYears(). However, I noticed that
it takes a different value for the month. Why is it that the age
values taken by LinearAxis is the index instead of the month value
in the xml? Say, the age month value in the xml is 24, the value it
evaluates is 0, then if the month value is 24.5 it takes 1, so on
and so forth. How can LinearAxis takes month as the value to be

Horizontal Axis not showing when initial loading

Hi,
We are on Dashboard 4.1 SP3.
I have drilling down configured on the Dashboard report. The issue is when initial loading the dashboard. the horizontal text are not showing completly, untill I click the other column of the parent column, it shows the child horizontal text.
Could you please help.
Thanks,

Hi Dave,
There are some issues still in displaying the horizontal axis.
1844514 - Dashboard X axis labels are cutoff
As a workaround what you can do, use the range slider to make the date text to display vertically rather than horizontal or you can enlarge the size of the chart at the max to make them to display vertical.
Hope this helps!!!
